Fall Bulbs by Mike Darcy

I think that it is fun to deviate and plant some bulbs that, perhaps, are new to you. Here are a few suggestions.

Relatives of the edible onion, Ornamental Alliums can make a beautiful showing in the early to mid-summer garden. The flowers usually appear in clusters on bare stems. There are many different sizes to choose from with some only getting 6 inches in height with others reaching 5 feet or more. Usually, the flowers are shades of blue but there are some pink and white forms. ‘Lavender Bubbles’ is a small compact type that would fit into most garden settings.

Galanthus (Snowdrops) are among the first of spring bulbs to bloom. Their nodding, white, bell-shaped flowers are a signal that spring will soon be here. These are ideal for planting in rock gardens, under flowering shrubs, or to grow in pots. I have found that they like a little bit of shade or filtered sunlight. Galanthus ‘Flora Pleno’ has a double layer of white flower petals that are tipped green.

When we think of daffodils, we usually think of the yellow flowering trumpet type. The trumpet types are very easy to grow and tend to naturalize much more so than tulips. Technically all daffodils are Narcissus’, but we usually refer to the trumpet type as daffodil. The selection ‘Julie Jane’ has a very unique flower form and is ideal in a pot.

If you don’t mind waiting a few years, and your garden has the space and the right conditions, and if you want to make a spectacular statement with summer flowering bulbs, Cardiocrinum giganteum, (Giant Lily), might be the plant for you. This is sometimes referred to as the Giant Himalayan Lily, and with good reason. Even though it might take it 5+ years to bloom, depending on the size of the bulb, it is well worth the wait. The flowering stem can reach 8 feet or more in height with 20+ fragrant flowers on a single stem. This bulb prefers a light shady location, a woodland setting could be ideal, and a soil rich in humus. Black Gold® Natural & Organic Garden Compost Blend would be a good addition at planting time.

It seems as though the selection of fall bulbs expands every year and garden centers are offering more choices. That is good news for gardeners. If you have a special bulb you are looking for, buy early. With supply and transportation issues, garden centers do not always have an option to reorder. Think ‘out of the box’ when planting and don’t limit yourself to only planting in rows. Plant bulbs in mass plantings or groups. The reward in the spring will be worth it!

Plants That Perform In the Hot Summer Sun

We have had some very hot weather here in the Pacific Northwest and in some cases previous high temperature records have been broken. Not only have we had very hot and sunny days, but there has been no recent rain and the ground is very dry. It is not unusual for us not to have rain in the summer months, but with no rain and high heat, plants can suffer. The diversity of plants always continues to amaze me with some being able to thrive in the hot sun, while others wilt, and the leaves burn.

Most gardeners have their favorite plants for sunny locations and much of the information on these plants is probably trial and error. I have certainly had my share of plants that I thought would perform well in a sunny location, only to find out that I was mistaken and they either died or the leaves became scorched. A helpful hint, that I have mentioned in previous articles, is adding Black Gold® Natural & Organic Just Coir over the soil surface. Coir has high water-holding capacity which is a helpful addition to summer plants growing in containers.

The following is a listing of plants that seem to thrive in the sun and provide summer color with flowers and/or foliage,

One of my favorites is Bougainvillea ‘Raspberry Ice’. While Bougainvillea is mostly known as a tall and fast-growing vine, ‘Raspberry Ice’ is a low mounded spreading form which makes it ideal for pots and hanging baskets. With variegated foliage, this plant is attractive even when not in flower with the typical purple flowers, actually bracts. Bougainvillea is a tropical plant and will not survive our winters and I treat it as a summer annual.

What’s not to like about Zinnias. An old-fashioned flower that continues to be popular in gardens of today. The color range is vast with colors of red, yellow, cream, white, pink, purple and shades of all of these. The plants have a wide range of height, some are low growing, others tall, and many in-between. They bloom all summer, and the flowers are excellent for cutting.

There are two new Coreopsis in my garden this year and both have been blooming since I bought them in early June. This easy to grow member of the sunflower family has flowers and foliage that are quite diverse. Coreopsis ‘Lightning Bug’ has fern-like foliage and small flowers that cover the plant. Coreopsis ‘SuperStar’ has larger flowers and foliage. With their vibrant flowers, a grouping of either provides a bright spot of color in the garden.

With hundreds of small flowers on a single plant, Cuphea is known not only for the prolific flowers it provides all summer, but the flowers are also known as a hummingbird magnet. Sometimes call the cigar plant because the flowers are orange-red with a white tip and a dark rink at the end. For a plant that gives continuous color, it’s hard to beat Cuphea!

The large bold leaves of a Canna can give a garden a tropical look. With the leaves varying from solid green to different variegations, they can provide color when the plant is not in bloom. Two that I particularly like are ‘’Bengal Tiger’ and ‘Cleopatra’, both of which have outstanding foliage. ‘Bengal Tiger’ has yellow-striped variegated leaves with a narrow maroon margin and bright orange flowers. ‘Cleopatra’ has leaves that may be partially a dark chocolate color and green or all green or almost all dark chocolate. The flowers are equally variable and can be red, yellow, and often of combination of both colors. It is a very eye-catching plant in the garden.

 

These are just some sun loving plants that perform well in Pacific Northwest gardens. I find it interesting to try some new plants every year to test their summer sun worthiness. Many of these plants are available at garden centers and can still be planted. The plants will probably be larger than they would have been in the spring and can provide some instant color in the garden. Try one that is new to you!

 

Happy Gardening!

Summer Color by Mike Darcy

With the cool and rainy wet spring that we had here in the Pacific Northwest, most plants seemed to be about two weeks behind what would have been their ‘normal’ schedule. The weather delayed many gardeners from doing what would be some of their early spring chores. Not only was the weather not conducive for working in the garden, but the soil was too wet and muddy from all the rain.  Then in May, spring arrived with warm sunny days, and it was as if plants exploded with growth and bloom. Suddenly plants were no longer two weeks behind schedule but were on schedule.

As I walk around my own garden, as well as other gardens that I have recently visited, I am in awe of all the color that I see. Most gardeners always have room for another plant and the following are some of my favorites for summer color. Many of the plants that I use for color are in containers and I have found that adding a mulch across the top of the soil is a benefit to helping the plants thrive. Black Gold Natural & Organic Garden Compost Blend is an ideal mulch to help retain moisture. Another option is Black Gold Natural & Organic Just Coir which has excellent water holding capacity.

Hardy fuchsias would have to be near the top of the list for summer color. There is such a wide variety to choose from with size and color of the flower and the growth habit of the plant. Some will get quite tall, often up to six feet or more in one season, while the height of many stays in a three-foot range. Some varieties will even hug the ground and grow as a ground cover. Plant tags will often say sun to shade exposure, I have found they do best with some protection from the hot afternoon sun. One of my favorites is Fuchsia ‘Debron’s Smokey Blues’.

The flowers on Abutilon ‘Red Tiger’ do not look real but look like a fine stained glass art piece. This is a shrub and in a mild northwest winter, it will survive. A large plant in full bloom is stunning.

If there was ever a plant that was a work horse for blooming, I think it would have to be the dahlia. Most dahlias will begin flowering in June and there will be non-stop bloom until frost. The color range is vast and there is almost every color except blue. The flowers are also variable in their shape as is evident by the photos. These pictures were taken last summer in the trial garden of the Portland, (OR), Dahlia Society which is located on the ground of Swan Island Dahlias in Canby, OR. These photos give a good example of the wide range of color and shape of flowers. Dahlias also make excellent cut flowers.

Our summer deck would not be complete without several containers of Salvia. Keep the flower stems picked when the blooms are gone, and many will bloom throughout the summer. Two of my favorites are Salvia ‘Black & Blue’ and Salvia ‘Amistad’. The flowers on ‘Black & Blue’ tend to be cobalt blue and ‘Amistad’ has flowers that are deep purple. Both are magnets for butterflies and hummingbirds,

Sometimes, I think it is fun to grow plants that are known not to be winter hardy, but nevertheless will perform well during the summer. The Princess Flower, (Tibouchina), is one such flower. It will bloom with purple flowers all summer and into the fall. It will not survive our winters outside and so mentally; I consider it an annual. It is fast growing and flowering can be profuse. Excellent for growing in a container.

I realize that I have barely touched the list of plants for summer color, but the above-mentioned ones should all be readily available and easy to grow. Perhaps one is new to you, and you will give it a try. Most gardeners are always trying something new. Who knows, it might just become a favorite!

Hanging Baskets by Mike Darcy

Hanging baskets and the month of May seem to go together. On a recent visit to several different garden centers, the selection of colorful hanging baskets was vast. It was not that many years ago that fuchsia baskets were the most common, but that is not the case today. Yes, there are certainly fuchsia baskets but there are so many more options available. Many of the baskets today, do not have just one type of plant, but multiple different plants in any one basket.

If I had to pick one plant that I saw consistently in multiple baskets, it would be calibrachoa. Whether planted singly or with other plants, this petunia relative is ideal for trailing in baskets or pots and blooms all summer. Plants in garden centers are blooming now and with the wide range of colors available, it is easy to pick specific flower colors. Other plants that are widely used include, petunias, verbena, begonias, fuchsias, bacopa, geraniums, and lobelia.

Before making a purchase, consider where the basket will be in the garden. There are baskets made for sun, for shade, and for a sun/shade mix. There are two choices in purchasing hanging baskets, buying one that is already made, or making one yourself. Keep in mind that the already made baskets have probably been in somewhat of a controlled environment and might need a little extra care until they get established. For example, a basket made for a sunny location, might not have been in a full sun location and so it may need some protection on hot sunny days until it becomes adjusted to its new  environment.

Making your own basket can be a fun project and you get to pick exactly the plants that you want. Making a basket is also a good way to get kids involved. Once you have selected the container, use Black Gold® Moisture Supreme Container Mix as your potting mix. This mix has excellent water retention qualities and on hot summer days, hanging baskets can dry out quickly. Select your plants and place them closer together than they would normally be in a flower bed. This will give you a blooming basket sooner than if the plants are spread apart.

An herb basket can be ideal if a kitchen door is close by. Try planting basil in the center and plant thyme along the sides. This can be both beautiful and functional.

Watering and fertilizing are both key to keeping baskets looking good all summer. Being exposed to the elements, especially the sun and wind, baskets can become dry quickly. They will often need to be watered once a day. The city where I live has had a hanging basket program for many years and a maintenance is contracted to water them once a day, even if it rains. As the season progresses, the plants will get thick with leaves and the leaves can prevent the rain from reaching the soil. Because the plant is being watered so often, nutrients are often leeched out and need to be replenished. Fertilize weekly with a water-soluble plant fertilizer.

The choices for a basket are limitless. Try something new and enjoy your creation all summer!

Camellias in the Garden by Mike Darcy

Camellias have been a part of American gardens for several hundred years. Native plants to China, Japan, and SE Asia, some plants were probably brought to England in the 1700’s. At this time, they were primarily grown in conservatories or greenhouses. Camellias would be grown in containers taken outdoors in the summer and back to a protected location for the winter. In probably the early 1800’s, they began to appear in the United States. They quickly became popular in the southern US because it became known that they were not quite as winter tender as had been previously believed. In many southern states, Camellias would thrive as shrubs in the garden.

 

Today, camellias are found in many regions in the US except some of the coldest. With thousands of varieties to choose from, some are more winter hardy than others and a local garden center is a good place to check out which varieties they carry. The bloom shape and color range of camellias is vast. Over the years, it seems as though camellias have had a love/hate relationship with gardeners. They have been very popular, then they went into a decline, and now seem to be staging a strong comeback.

 

While there are probably overt 200 different species, the two that are most widely planted are Camellia japonica and Camellia sasanqua. These two species would also be the most prevalent in garden centers. As a general rule, the japonica type is what most gardeners have in mind and is what they think of when they hear the word camellia. Some names to look for are; ‘Bob Hope’, deep red with gold stamens, ‘Kramer’s Supreme’, very large red peony shape flower, ‘Carter’s Sunburst’, large pink flowers with deep pink stripe, The japonica types usually have a peak blooming season in late March and April. Bloom times can vary greatly depending on the particular variety so be sure to check the plant label tag.

The sasanqua types are also popular, but usually have smaller flowers and bloom in late fall and early winter. ‘Yuletide’ is a popular red that usually blooms during the Christmas holiday season. The flowers are single but can be profuse and continue to bloom for several months. Many of sasanqua types can be easily trained to espalier on a wall or trellis. In my garden, I have the sasanqua variety ‘Setsugekka’ trained on a trellis. It has a long season of bloom during the winter and is covered in single white flowers.

 

Camellias like a similar environment to that of rhododendrons. While there are many examples of them being planted in full sun, I believe they prefer some shade from the hot afternoon sun. They like a well-drained soil that is rich in organic matter. Black Gold Natural & Organic Garden Compost Blend would be a good choice at time of planting. Also, Black Gold Natural & Organic Cocoblend Potting Mix would be a good choice to use in areas that might be susceptible to particularly drying conditions. Camellias are often planted under the protection of trees with roots that might be robbing a camellia of moisture. Coir, used in this mix, has excellent moisture retention properties. Newly planted camellias will need supplemental water during the summer months. On older and established plants, supplemental watering may not be necessary. Sometime due to space considerations, pruning may be required and if so, it should be done right after flowering.

April is an excellent month to plant camellias and many plants will be in bloom so selecting the right color and bloom form is easy. As mentioned earlier, the selection available is vast and garden centers usually have their best selections at this time. The delicate looking flowers of camellias can be deceiving to the tough and easy to grow plants that they are. Camellias also make excellent plants for container gardening.

Prepping for Spring by Mike Darcy

I like to refer to February as the month to get ready for spring. Most of us have some garden tasks that we have yet to complete, and this is a good time to get them done. Living in the Pacific Northwest, this winter has been a mix of temperatures, both mild and very cold, (for us). In late January/early February, temperatures dipped into the low 20’s and we will have to wait until spring to really discover what damage was done to our plants.

Years ago, I was given a Musa basjoo, often called ‘Hardy Banana’ because the tops will die to the ground after a freeze, but the roots will survive, and new banana shoots appear in the spring. Musa basjoo is fast-growing and likes a soil rich in humus. When planting, add Black Gold Natural & Organic Compost Blend into the soil.

Photo above, is what my plants looked like after a frost. This was a major winter cleanup chore because I cut all the stalks to ground level and then put the leaves in my compost bin. This is a rather barren spot right now, but I know what it will look like in late spring and summer.

Hardy fuchsias are treated differently. I have found that after freezing weather, the leaves on hardy fuchsias all turn brown and the stems look as though they are dead. However, it is difficult to tell just how far back the stems have been killed. If hardy fuchsias need to be pruned because of space considerations, I suggest waiting until later in the season because I have often found that on many of the stems that I thought were dead, new shoots will appear.

While it is too late to plant bulbs of Galanthus, well known by their name ‘Snowdrop’, some garden centers will carry pots of blooming plants which can be planted now. Bulbs should be planted in the fall. These are among the first bulbs to bloom in late winter/early spring. Plant them in an area where they can naturalize such as under a shrub or in a woodland setting. They like a moist soil and adding Black Gold Natural & Organic Garden Compost Blend at time of planting would be a benefit.

We should also think about what, I would call some of the more mundane tasks. Before pruning, check pruners and make sure they are sharp and well oiled. Shovels, rakes, and trowels should be cleaned. February is also a good month to get the lawn mower tuned up, so it is ready to mow once spring arrives.

While the February weather is not always ideal for working outside, we usually have some days, or partial days, when there are sun breaks. As you walk around your garden, when you see new growth emerging, check for signs of slug damage. I have seen many very small slugs in the garden, and they can do significant damage on newly emerged plants. Take appropriate control measures.

 

The garden is meant to be enjoyed, don’t let the tasks overwhelm you!

 

Happy gardening!

The November Garden

 

 

November is a sort of in-between month. Our warm days are gone, and we are into, what I would call, a typical Oregon fall season. The daylight hours are shorter, the rainy season is here, day and nighttime temperatures are cool and sometimes cold. Yet, there are still many plants providing color with flowers, foliage, and berries.

On this November day, my hardy fuchsias are still blooming and show no signs of letting up. In my own garden and others that I visit, hardy fuchsias have been amazing this year. They seem to perform equally well in both pots and planted in the ground. Contrary to popular belief that they need shade, many in my garden receive sun for most of the day. They should continue blooming until we get a frost, although with continuing days of rain and cold weather, their bloom will diminish.  As an added precaution to give the roots some protection during the winter months, I add 3-4 inches of compost around the base of each plant. Black Gold Garden Compost Blend would be ideal. Some gardeners prune the branches severely after a frost, but I have found that sometimes branches that appear to be dead are actually not and new buds will appear in spring.

It is not too late to plant spring flowering bulbs, favorites like tulips, daffodils, hyacinths, and crocuses are the most common. All of these do well in pots, and it can be fun to try different combinations. Using Black Gold Natural & Organic Potting Mix should get your bulbs off to a good start. Try planting crocus around the rim of the pot and then plant pansies over the top for instant winter color.

Many gardeners like to try new plants or bulbs in their garden. While tulips, daffodils, hyacinths, and crocuses are the mainstream spring flowering bulbs, Galanthus, (Snowdrop), should not be overlooked. Bulbs can be planted now and, in the spring, they will be among the first bulbs to bloom as the winter is ending. Their clumps of nodding bell-shaped flowers are pure white and are a delight to see on a winter day. Snowdrops are a good plant for a rock garden as well as for under shrubs where they can be allowed to naturalize. They prefer a soil rich in humus such as Black Gold Garden Soil. Work this into the soil at the time of planting.

There are also many deciduous trees that provide us with some spectacular fall color.

Certainly, one of the best is Oxydendrum, (Sourwood). The autumn foliage can be in shades of orange, red, purple, and all shades in between.

There is a huge array of Japanese Maples to choose from. The leaves can vary widely in shape and color. This is an excellent time to visit an arboretum or your local garden center to see what varieties are available. It is often more accurate to see the leaf color in person rather than relying on a photo. The two below are favorites in my garden.

Acer palmatum ‘Shishigashira’:

Acer palmatum ‘Fairy Hair’:

Of course, the work in the garden is never done and a few non-plant winter tasks would be to clean and oil the lawn mower, clean and oil and sharpen pruners, rake and compost leaves, and look through seed and plant catalogs to get ideas for spring!

Enjoy the fall garden and don’t be limited to the plants mentioned here, especially regarding leaf color.  The list for trees and shrubs for fall leaf color is vast. Walk around your neighborhood and visit other gardens to get ideas.

Summer Garden Tasks

by Mike Darcy

The spring season of 2022 will not go down the annals of ideal gardening weather here in the Pacific Northwest. We had record rain and cool, (cold), days and nights which delayed the typical planting season for many gardeners. Warm season vegetable crops like tomatoes, squash, beans, etc. were delayed until late May and early June. Many gardeners also delayed buying their hanging baskets and flowering annuals as well. While this cool and rainy weather put the garden season behind the usual schedule, it did not take long for plants to put on vigorous growth and now it appears that they are where they should be for July.

There are lots of tasks for July but most important is to enjoy your garden and don’t get overwhelmed.

With container gardening, keep in mind that potted plants will dry out much faster than if they were in the ground, Usually, daily watering is necessary especially for hanging baskets. Adding Black Gold Just Coir to the soil surface of pots will help to hold moisture. Also, check pots to be certain that they are draining adequately. I’ve found that drainage holes can get plugged and it may be necessary to take a piece of rebar or heavy wire to unplug them.

It is not too late to add some color to your garden. Most garden centers carry summer blooming annuals, and these can easily be potted in your own containers for some instant color. No one has to know that you just planted them! Be sure to use a potting soil that will help hold moisture. I like to use Black Gold Natural & Organic Potting Mix, because with pumice or perlite, it will also ensure good aeration.

 

Dahlias will be coming into bloom this month and should continue through the fall or until there is a frost. Keep the flowers picked for continuous bloom. Earwigs seem to prefer dahlia flowers over many others and if you see the flower petals being eaten, that is probably a sure sign of earwig damage. Take a flower apart and you will probably see them. Control as necessary, always following label instructions. Dahlias need regular summer watering and if the soil constantly dries out quickly, add Black Gold Garden Compost Blend. Tall growing dahlias usually need to be staked

As the name suggests, Hydrangea is a moisture loving plant. While some can grow in a full sun location, I’ve found they do best with some afternoon shade. They are quick to wilt with lack of moisture, but also quick to bounce back. A mulch of Black Gold Just Coir, especially during the summer months would be beneficial.

Some of the smaller fruited tomatoes may be beginning to ripen. Be sure tomato plants have good drainage and adequate water. Tomatoes have an extensive root system so water them deeply. If they stress for water, they may drop the fruit. Plants often get very dense with growth, and it is a good idea to thin some of the branches and leaves to increase air circulation which can help prevent some diseases. While it is too late to plant tomatoes, if you did not get a spring vegetable garden planted, make plans for a fall one in mid-August. While the crops will vary from spring, there is much that can be planted for a fall harvest.

 

 

Take some time to enjoy your efforts. I like to have a walk through the garden in the early morning and just enjoy the peace and quiet. I have many plants that attract hummingbirds, and it is a delight to watch them in action. I have other plants for attracting bees and other insects as well as an assortment of birds and several sources of water for all. I strive to be respectful of our planet.

The Best Reblooming Clematis

When visiting older established gardens, if there is a border garden, it will probably contain at least one of these three plants: peony, bearded iris, and clematis. These are often considered old-fashioned plants because they have been regularly planted in gardens for so many years. All three of these plants are generally considered reliable spring bloomers and once blooming. The bloom period can be over several weeks, and there are usually early and late-season varieties, but their flowering time is usually spring and early summer with additional flowers not expected until the next spring. There are, however, exceptions.

Over the past several years, there has been a resurgence of interest to select those that will rebloom. This is especially true with clematis, and with a little effort, a gardener can have plants that will rebloom once and sometimes even twice. I recently discussed reblooming clematis with Linda Beutler, curator of the Rogerson Clematis Collection in Lake Oswego, Oregon, and here are some of her thoughts.

Reblooming Clematis Care

Most clematis grow best in the full to partial sun and like to have their roots shaded and their tops in the sun. After a clematis has flowered, deadhead it, (remove old flowers) and do some light pruning if necessary. Deadheading prevents the plant from setting seed and light pruning removes any dead stems and opens the plant up to more sunlight. Fertilize the plant at this time. Linda said a rose & flower fertilizer is generally good. At the Rogerson Clematis Collection, they use a fertilizer with an NPK, (Nitrogen- Phosphorus-Potassium nutrient numbers on the bag or box) ratio with numbers under 10. Currently, they use a 5-7-2. Often, 30-45 days after fertilization, the plant will re-bloom. For a full list of care tips, visit the Rogerson Clematis Collection page on clematis care (click here).

Five Recommended Reblooming Clematis

Naturally, some plants will consistently rebloom easier, and for that consistent rebloom the following are five clematis varieties that Linda recommends.

  1. Clematis alpina ‘Pamela Jackman’ (Zones 3-9) flowers first in April and reblooms well, often in late summer. It requires trellising and can also be grown well in a container. With this clematis, you can have April in August.
  2. Clematis ‘Elegant Rhythm’ (Zones 5-9) is a handsome herbaceous perennial clematis named and introduced by Joy Creek Nursery. If you do not allow it to set seed, it will rebloom through late spring and summer, just like annual Scabiosa or perennial Astrantia.
  3. Clematis ‘Duchess of Edinburgh’ (Zones 4-9) is a double that can bloom as many as three times in a long growing season. Deadhead the spent blooms and fertilize with most any fertilizer for roses. The fully-double flowering clematis will often produce flowers that are less doubled when they rebloom.
  4. Clematis ‘Blue Ravine’ (Zones 4-9) is an excellent large-flowered variety and has the added advantage of flowering well—if paler—in partial shade. The photo above was taken in September 2020 and looks as though it were in spring.
  5. Clematis ‘Niobe’ (Zones 4-9) is a deep-red variety (pictured below reblooming in the autumn). Look closely at the image and you can see this clematis is growing through and is supported by another plant. This particular support plant is Osmanthus heterophyllus ‘Goshiki’.

Clematis are often grown in this way using another plant for support. Often some of the old garden roses are used because they not only offer a good support system, but the clematis will flower again when the once-blooming roses are finished.

If you are visiting the Pacific Northwest, and have any interest in clematis, be sure to visit the Rogerson Clematis Garden, which is part of the Lake Oswego, Oregon, Parks & Recreation system. With over 900 taxa represented, it is the most comprehensive collection of clematis within a public garden in North America. Admission is free.

Spring Garden Tasks for a Happy Garden 2022

Spring is here! Officially it was March 20th, but I knew it was spring as soon as I saw the daffodils emerge. The hellebores have been glorious this year, but as their late-winter flowers slowly fade, new colors appear in the garden. The red stems of the peonies have started to peek out after being dormant all winter, the early magnolias are blooming, and the sweet fragrance of daphne lets my family know that spring has begun.

This is a wonderful time of year in the garden, with lots to do but so much to be thankful for. Yes, there are many tasks required, but most of those tasks are not burdensome. Instead, they are rather enjoyable because as gardeners, we are getting ready for a new growing season with lots of promises in store.

Refreshing Garden Containers

By refreshing the potting soil in your spring and summer containers, you will find that they perform much better!

One of my early tasks is to freshen up my many containers, of which I have 100+ scattered throughout the garden. It is a chore, no question about that, but I always like to add new potting mix to containers as needed. In some of the large pots, instead of removing all of the older potting mix, I take out about half and add new and mix the two together. In most of the smaller pots, if the mix has not been changed for a couple of years, I empty the old and add new. With the old mix, I use it around established trees and shrubs in the garden as a mulch.

My planting mix of choice is Black Gold Natural & Organic Potting Mix. Last year, we had some extremely hot days, and it was difficult to keep pots adequately watered. This year, I am going to add some Black Gold Just Coir to the mix because it should help with moisture retention when temperatures are high.

Prune Early Spring-Blooming Shrubs

Prune spring-flowering shrubs, like this Viburnum, just after they flower to keep from removing next year’s flower buds.

As some of the early-blooming flowering shrubs, such as Forsythia, finish their blooming period, it is a good time to do some pruning if necessary. Remove any branches that tend to be older and weaker because this pruning will encourage new growth that will then bloom next year.

This has been a superb spring for Camellias, and I cannot remember a time when I have seen so many plants with so many flowers. As the flowers fade, they should be removed. Often plants grow much larger than we had intended when they were planted, and I think Camellias are a good example. After they bloom, it is an excellent time to do any necessary pruning.

Get Spring and Summer Vegetables Started

Now’s the time to plant spring herbs and vegetables, such as this dill, lettuce, and cilantro.

While it is too early to set out tomato plants and other summer vegetables, there are many cool-season vegetables that can be planted now. Vegetables, like lettuce, cabbage, broccoli, and cauliflower can be planted now, and garden centers should have a good selection available. Tomato seeds can be started indoors, and the plants will then be ready to set outside in late May or early June. Peas can be sown outdoors, both edible peas and flowering sweet peas. Sweet pea seeds have a very hard coating, and I have found that soaking the seeds overnight in a bowl of water prior to planting, will speed up germination. (Click here to discover more seeds that appreciate soaking.)

Prune Roses

If you failed to prune your roses earlier in the season, there is still time.

Roses should have been pruned in late winter or earliest spring, but if not, it is better to do it now rather than not at all. Your flowers will probably appear later, but the bushes will be more compact, and the flowers will be within reach.

Don’t let the many tasks of the spring garden overwhelm you. A garden is meant to be enjoyed and to be a place of peace and tranquility. Take the time to enjoy it, most plants are resilient and can stand some neglect. The garden never has to be perfect. It is a growing entity that is constantly changing. Enjoy the changes with it.
