Mike Darcy on September Gardening and Outdoor Rooms

Once September arrives and school starts, I consider summer over. I realize it is not “officially” over yet, but September is a time to relax, enjoy the garden, and scale back.

Cuphea
Cuphea micropetala

As I walk through my September garden, it is bursting with color. The fuchsias, salvias, and abutilons are in full bloom, and all are hummingbird magnets. A relatively new plant in my garden is Cuphea micropetala.  While it is technically a tender perennial, I do not think it would be winter hardy here, so I am growing it as an annual. If it survives the winter, I will be pleasantly surprised next spring.

This Cuphea has been in full bloom since mid July and shows no signs of stopping. My plant is in a large pot and gets hot afternoon sun which it seems to love. With its tubular flowers, it is also a great hummingbird attractant. This is a plant I would suggest adding to your list for planting next spring.

Outdoor Rooms

Outdoor living spaces have become very popular, so I have added a small “outdoor room” to my garden.  Just having a quiet space with a table and chairs tucked away in the garden can create a feeling of relaxation. Sitting in the shade on a sunny day is very welcome and enjoyable.

More elaborate outdoor seating areas are also becoming more and more popular. I recently enjoyed seeing one at the home of Portland Garden Designer, JJ DeSousa. Her outdoor living space consists of a poured concrete patio fitted with appealing patio furniture surrounded by fenced garden. It is very inviting for conversations. When I have been at functions in her garden, this is the place people gravitate to. The photo of her patio garden might look large, but it is not. Her home and garden are on a small city lot, but she makes great use of the space.

Fall Garden Redesign

September is also a good time to walk through your garden and look at areas that could be improved. Consider places where plants can be taken out, added, or re-arranged.We all make garden mistakes, and this is a good time to correct them. In my own garden, I have plants that have grown too tall for their space and require transplanting to a new location. I also have bare spaces to fill with plants that will look good late in the season.

This is also a great time of year to consider adding garden art. A feature that I have seen in other gardens and have incorporated into my own is the use of large pots. At one time, I thought having a pot meant that it needed to be filled and planted. This is not the case. Many beautiful pots I consider to be standalone pieces of garden art that I strategically place throughout my garden.

As I write this column in early September, we are having temperatures in the 80’s. It is what I consider perfect fall weather with warm days and cool nights. However along with the warm days, there have been some drying winds. With hot sun and drying winds, exposed container plantings quickly dry out, so I maintain a rigorous watering schedule and use Black Gold Natural and Organic Potting Soil to help roots hold moisture.

BG-GRDNCMPST-BLND_1cu-FRONTAs I look at the soil in my garden beds, there is a big difference in the areas where I worked in Black Gold Garden Compost Blend. Those without compost are hard, dry, and cracked. The areas where compost was look great and require much less water.

Consider September as the month to review what was good in your garden and what was not so good. Take pictures to make a record of your successes. I am going to do that as I continue to improve and make changes in my own garden.

 

Enjoying Summer Gardening

Here it is July and summer has finally arrived in the Pacific Northwest.  It took quite a long time for this to happen as our spring was one of the coolest and wettest on record.  But now that summer is here, what a glorious time of year it is.  As some garden friends have told me; this is why we live here and perhaps it is because we have had such a gloomy winter that when we do see sun, it is a cause to celebrate.

Finally summer herbs and vegetable gardens can safely be planted.  In my own garden, I have finally planted Basil.  This is a plant that loves the heat and if planted too early will often die.  A nursery grower told me earlier this spring that she tells people not to plant Basil until July 4.  In my garden, we have two ‘trough like’ planters and that is traditionally where the Basil goes.  It is an area that receives hot sun in the afternoon and in previous years the plants have thrived here and I do not expect anything less this year.

For Basil and other herbs in containers, I use Black Gold Natural & Organic Potting SoilThis has proven to be an excellent soil and one that I have used for many years.  Just prior to setting the Basil transplants in the containers, I add an all-purpose fertilizer.  I find that generally one application of this fertilizer at planting time is usually sufficient for the season.  Some varieties of Basil will tend to reduce leaf production if the plants are allowed to flower and I always try to remove the flower stalks.  This prolongs the usefulness of the plants and we generally are harvesting leaves until cool weather arrives in the fall.  It is also a good idea to apply some slug/snail bait around new plants.

Another great container plant and one we have had on our deck for the past several years is Cyperus papyrus (Giant Egyptian Papyrus).  I treat it as an annual plant in our climate as I have not had success with it surviving a winter, especially in a pot.  This is a very striking plant and always draws attention.  The tall green stems can reach 6 feet or more and the stems are topped with clusters of thread-like green parts.  We have our plants in front of a tile garden art piece and while the plant is native to Africa, it fits very well in an Asian garden.  This is a plant that requires plenty of water and an excellent mix to use is Black Gold Cocoblend Potting Soil.  This potting soil is a mix of coconut fibers (coir) and peat moss with the addition of earthworm castings and pumice.  The coconut fibers are excellent at retaining water which is ideal for a plant like this.

Veriegated BrugmansiaIn previous web articles I have mentioned Brugmansia (Angel’s Trumpet) and what a great show of flowers these plants can provide.  For one that will provide color even without flowers, consider a variegated type.  We have two of these in urns placed in the entryway as one would enter our back garden area and with all the solid green leaves surrounding them, the variegated leaves really make the plant stand out.  Brugmansia is fast growing and likes both heat and water.  It makes good sense to use Black Gold Waterhold Cocoblend Potting Soil to help retain water.  At this time of year, many garden centers will have Brugmansia available in 5 gallon size containers and thus you can get an instant effect.  Fertilize every ten days to two weeks as Brugmansia is also a heavy feeder.  I always add some blood meal at time of planting to encourage growth.  Be careful using blood meal when the weather is hot as it can burn if applied too heavy.  At this time of year, I would just add a light application at time of planting.

Showy Garden Flowers

If you have read my columns before, you know I am a fan of Salvia.  While my favorite is ‘Black and Blue’, I like to try new varieties.  A new one for me this year is Salvia ‘Oceania’ with sky blue flowers.  I have three plants in a pot on our deck and they have not been without flowers since they were planted in May.  The blue color of this Salvia is sure to draw attention of anyone visiting your garden.

If the soil in your vegetable garden seems to be drying out, this is an excellent time to apply Black Gold Garden Compost Blend.  Work this lightly into the soil around vegetable plants and it will improve water retention and give the garden a more finished appearance.

At this time of year with so much happening in the garden, don’t forget that one of the purposes of why we garden is to enjoy it.  Make some time to enjoy your garden and let it be a calming place.  In my own garden, one of my favorite times is early morning and to water the plants by hand.  It is usually a quite time and I enjoy the solitude which I do not mind sharing with the hummingbirds.

If you have some bare spots in your garden, check out your local garden center as most will have blooming summer flowers in pots to set out for instant gratification.  Enjoy!

Cool to Warm Weather Gardening in Spring

Raised bed gardening in the Pacific Northwest.

Here in the Pacific Northwest temperatures seem to be getting warmer and warmer in the spring. We have finally had some sunny days, and the temperature actually reached the 80’s. How nice it was to see the sun, and what a wonderful feeling to get outside in the garden without a jacket.

I always like to visit other gardens and made a recent visit to the garden of a friend to check on the status of his garden peas. Since peas like cool weather, they have done just fine. It is so nice to see his raised vegetable beds. He worked Black Gold Garden Compost Blend into the soil at time of planting, and the plants look great. The fine compost gives his beds a ‘finished’ look.

If you have held off on planting your summer vegetable garden, it should be all right to do so now. Beans are very easy to grow BG-GRDNCMPST-BLND_1cu-FRONTfrom seed. Once the soil has warmed, they germinate quickly and are a good crop for children to grow. Cucumbers, squash, pumpkins, and corn can also be planted from seed. If you just need a few plants, save time by buying individual starts at your local garden center.

With the arrival of warm weather, basil can finally be planted. Basil definitely needs heat and is one of the last plants I set out in spring. I wait until the nights and days are both warm. Try growing basil in containers on a deck or patio. As long as it has full sun, it should thrive. At our house, we always have basil in several pots on our deck. Black Gold Natural & Organic Potting Soil is a great mix for basil planting. (Basil deserves to be planted in an organic potting soil!)

There are many different types of basil to grow. In addition to the familiar large-leaf Italian sweet basil, consider growing ‘Dark Opa” for its flavorful dark-red leaves or ‘African Blue’ for its purple-tinted leaves. A new one for me this year is ‘Pesto Perpetuo’, which has variegated leaves that are light green with a cream margin. The contrasting color of the leaves make this basil stand out nicely against the reddish stems.

This shaded bed shows the large leaves of my Gunnera towards the back behind the hostas.

Gunnera tinctoria is a plant that always amazes me with its giant leaves and fast growth. Mine are already over 6 feet tall and growing. My Gunnera is also sending up a flower stalk which looks somewhat like a corn cob. Sometimes garden centers will label Gunnera as “The Dinosaur Food Plant” because it is an ancient plant and is found in fossils. Here in the metro Portland (Oregon) region, I have had good success with Gunnera even though it is not considered winter hardy here. Once we have had a frost, I cut the huge leaves and cover the crown of the plant with them for winter protection. I then cut the stems and insert them through the leaves and into the soil to help anchor them. This has provided enough protection for my plant that it has survived for the past five years even though we have had some very cold temperatures.

My experience is that Gunnera does best with some shade, especially protection from the hot afternoon summer sun. It also requires plenty of moisture and a soil rich in humus. I planted mine with about a 50% mixture of Black Gold Garden Compost Blend and good garden loam. I also use two applications of an all-purpose fertilizer later in the season.

Roses should be coming into bloom, and this is the time to fertilize them with a quality rose food. Roses expend so much energy with their continuous flowering, it is wise to fertilize on a regular basis (perhaps every four weeks) during the growing season. I always like to make one application of blood meal because of the high- and fast-acting nitrogen content. For an easy-care shrub rose, consider a Knock Out®rose. While not the traditional cutting rose, ‘Knock-Out’ bears flower clusters that bloom all summer, and it has never had a trace of disease.

Knock Out® Rose

The hardy banana, Musa basjoo is another good summer plant for Pacific Northwest gardens. When the word ‘hardy’ is used, it refers to the roots as being hardy, not the leaves. Like a perennial, this plant will die to the ground in the winter and return from the roots in spring. I have had it planted in my garden for over 10 years. When the first frost comes, I take the old leaves and cover the entire ground area with them.

I am amazed at how tall my hardy banana has already grown this year, considering our cool weather.  Typically, I apply a quality all-purpose fertilizer as it begins to grow. By the end of August, it will reach 12 feet and tower above most other plants in my garden.

Romneya coulteri

A final plant to mention is Romneya coulteri (Matilija Poppy). Each bloom has magnificent white crinkled petals with a cluster of yellow stamens in the center. The foliage is bluish, so the plant attracts attention in the garden, even when it is not in bloom. If you are looking for a plant that will grow well in sunny, hot, dry space, this is it. The only other requirement is that it needs good drainage. Once established, no summer watering is required.

So many plants to choose from! Check out your local garden center, and try something new. I always try to find some plants to add to the garden that are not familiar but look exciting.
