What Soil Eliminates Fungus Gnats?

“What soil will eliminate gnats on my Meyer lemon tree?” Question from Mokocody of Greenwich, Connecticut

Answer: Fungus gnats and their larvae live in and are attracted to all soils that are high in organic matter and moist. So, the soil and plant need to be maintained in a way that eliminates fungus gnats. I encourage you to watch the following video about how to remove fungus gnats if you have them.

How to Stop Fungus Gnats Organically

Whenever I buy a new plant or purchase a new bag of potting mix, I make sure the bag has no holes and the soil has no gnats. If any bag of soil you buy seems to have gnats, remove the bag from your home and return it immediately.

Happy Gardening!

Indoor Orchids Help Beat The Winter BLAHS!

 

Orchids will add a touch of glamour to those winter blue periods when you start counting the days until spring just for something to do. Most people have had only a passing acquaintance with an orchid, possibly as part of a corsage worn by you or your date to the high school prom or maybe a wedding party.

Their exotic coloration and growth habits add a whole new level of cool to the household. And orchids are cosmopolitan. They can be found in most terrestrial habitats of the world except glaciers. But the tropics harbor most of the known species (28,000+). Most tropical orchid species are epiphytes. That is they grow on tall plants like trees and vines to gain access to sunlight, a scarce commodity in a dense rainforest. But they do not get water or nutrients from them. Orchids from higher latitudes are rooted in soil. And all orchids are often incredibly picky in their habitat preferences. On top of that, European and American horticulturists have produced some 1,000,000 hybrids and cultivars since the 19th Century.

I suggest that you buy one or more orchids from a reputable dealer and raise them indoors. It will be good for the merchants, good for the orchids, and good for you as you embark on a brand new hobby. Everybody wins!

Popular Orchids to Buy

Phalaenopsis (foreground) are the most available orchid at stores in addition to Oncidium (background).

At this point, we have to dive into the practical aspects of orchids and orchid care. Unless you live in or near a big population center abounding with specialty stores, you should order online from a reputable dealer. I recommend going for a big show and buying tropical epiphytes. They are more glamorous and rewarding to grow. Temperate zone natives tend to do better outdoors where they get picked by the neighbor’s kids or chomped by chipmunks or mice.

Best bets for purchase include corsage orchids (Cattelya spp.), boat orchid (Cymbidium spp.), moth orchid (Phalaenopsis spp.), tropical slipper orchids, (Paphiopedilum spp.) and dancing ladies (Oncidium spp.). Epiphytes such as these may be potted in wood chips or secured to a piece of tree branch or piece of bark that mimics their forest habitat. Epiphytic aerial roots collect water and nutrients from air, rainwater, and organic debris that collects around the plant.  Despite the multiplicity of exotic forms, patterns, and colors, most orchids have no discernible scent.

You should buy mature plants that have blooms and/or live buds. They should be shipped in 4 or 5-inch pots on a wood chip substrate. Barring a shipping disaster they should provide you with instant orchids.

Cymbidium orchids come in shades of ivory, green, orange, pink, purple, and yellow.

Requirements for Home Orchid Care:

  • Position your plants on a bright windowsill facing east or west.
  • Most orchids require water once a week. When the orchid arrives, water thoroughly, then routinely as indicated above thereafter. Do not disturb the planting medium the plant comes in the first year or those first buds/flowers will not bloom!
  • Unless stated otherwise, Indoor air temperature should be no less than 60 degrees F. at night and no more than 90 degrees F. during the day.
  • Unless stated otherwise, Indoor relative humidity should range from 40% to 70%’
  • Feed weekly with a liquid fertilizer designed for orchids. We recommend a 10-10-10 formulation
  • Repotting with fresh orchid mix when your orchid stops blooming for the year. We recommend Black Gold® Natural Organic Orchid Potting Mix.
  • All of this verbiage notwithstanding, You will receive (or should receive) a set of care and maintenance instructions from the nursery. Follow those
Moth orchids are the most common type available at stores.

Happy New Year and please stay safe!

African Violet Care 101

It is that time of year when I start feeling desperate for flowers. Christmas, with all the decorations and lights, is past, and there are three whole months until April, with its early daffodils and crocus. So what is a perfect, ever-blooming houseplant, to brighten things up at this time of year?  The answer is African violets, and they are easier to grow than most think.

Basic Overview of African Violets

A happy African violet will bloom off and on throughout the year.

African violets (Saintpaulia ionantha) were discovered in 1892, in tropical rain forests in Tanganyika, a small country in eastern Africa. Baron von Saint Paul, the imperial, district governor of the colonized country, found them on the forest floor. He then sent plants and seeds back to his father in Europe, and after passing through several hands they made their way to the Royal Botanical Gardens, Kew, where the first breeding to develop them into houseplants began. They came to the United States in 1894 and by 1946 were so popular that police had to be called in to help with traffic, at the first US National African Violet Show in Atlanta, Georgia. The African Violet Society of America was founded shortly afterward in the same year.

As with any new plant, developing fancy varieties took off quickly, and now with modern breeding, there are fabulous African violets available. Plants range in size from 3 to 16 inches and can have single or double flowers in shades of pink, purple, violet, rose, or white. Some have frilled edges and others are bi-colored, with contrasting edges and centers. Violets that are splashed or speckled with two or more colors are called fantasy types.  Some have variegated leaves with edges, centers, stripes, or spots of white or yellow. Other have leaves with ruffled edges, quilted puffs, or an oak-like shape that add to the beauty of the plants.

Buying African Violets

Fantasy African violets are some of the most spectacular now available.

All garden centers that carry house plants should have a nice African violet selection, but specialty plants must typically be purchased online unless you have a specialty grower nearby. The Violet Barn is an outstanding online nursery for African violets, and, of course, looking at all of their wonderful varieties means that I plan to order some new African violets right away. They have an outstanding selection of unusual trailing varieties, and the fully-double, trailing-pink ‘Cirelda‘ caught my eye. The award-winning, heavy flowering, speckled-violet ‘Rob’s Boolaroo‘ looks unbelievable, as does the pretty pink-flowered ‘Ma’s Debutante‘ with its wonderfully white speckled variegated leaves. I was also attracted to some of the Saintpaulia species, such as Saintpaulia grandifolia, which is elegant and promises prolific violet-blue, butterfly-shaped blooms on long stems. Pretty African violet pots and a bag of Natural & Organic Black Gold African Violet Potting Mix are also on my to-buy list.

Growing Basics for African Violets

African violets require pots with drainage and bottom saucers.

Now, it is true that African violets have a bit of a reputation for being tricky to grow, but with a few instructions, you will easily have beautiful plants that bloom heavily and repeatedly throughout the year.

  1. Light: Providing the right amount and kind of light is important to keep plants blooming. African violets like bright, indirect light, which means putting them in a west- or east-facing window (large north-facing windows also work) and turning them every week for uniform growth. Artificial grow lights can also be used, if they provide consistent, uniform light. Keep the plants no farther than 12 inches away from the light, and provide 12 hours of light a day. If they start having fewer flowers, change the amount of light to 14 hours a day for a few weeks, and then go back to 12 hours. (Note: Grow lights really help in winter when you lack windows. This year, I brought three huge fancy geraniums in for the winter, but I lacked window space for them. I bought grow lights to keep them going until spring, and they are doing very well.)
  2. Water: Proper watering is essential for African violets. They require highly drained soil that is just moist. Room temperature water that is low in minerals is also preferred. When watering, avoid getting water on the leaves, which can cause leaf spots and damage. Instead, either bottom water or water from the top with a narrow-spouted watering can, while being careful to avoid the foliage. Allow water to stand in the bottom saucer for about 1 hour, and then pour it out. Allow the soil to dry out a little before watering again.
  3. Temperature & Humidity: The perfect humidity is 50-60% and temperatures close to 70 degrees F are just right.
  4. Fertilization: Fertilize with a specialty African violet fertilizer, which you can find online. Be sure to follow the manufacturer’s application instructions, because they may vary. I tend to feed them lightly each time I water.
  5. Soil & Drainage: Choose a specialty growing mix, such as Natural & Organic Black Gold African Violet Potting Mix, and always plant African violets in pots with drainage holes and a bottom saucer to catch water. When the plant becomes root bound, upgrade to a pot 1-2 inches larger to encourage new growth.

If your African violet stops blooming, check the number of rows of leaves. If there are 5 or more rows, cut the outside rows of leaves off at the base, back to 2 rows. Each row produces its own flowers, and the crown of leaves can take over the plant.  The most common cause of lack of flowers, however, is not enough light, so move it closer to your light source if plants stop blooming.

With new African violets on the way, I am thinking of places to put mine. My new trailing ‘Cirelda’ will look beautiful in a hanging basket. I cannot wait to see its pretty pink flowers and cascading stems. It should give me gorgeous blooms to brighten the winter and times beyond. For more information, please watch the helpful video below.

Bold, Sculptural Potted Succulents

These upright basketweave pots are texturally different, attractive, and add to the interest of the golden-edged ‘Laurentii’ snake plant and Aloe elegans they hold.

Some succulents have a real presence and panache. The best can fill a large pot, creating unmatched indoor or outdoor living sculptures. Most are long-lived and effortless to grow if provided a few cultural basics. These are the succulents to choose for bold, effortless gardening.

Before choosing your sculptural succulent, be sure to pick out an equally large, attractive pot that will hold it for several years. The container should be well-made, have drainage holes, and a reliable saucer at the bottom to catch water. Those that are glazed or sealed will hold water better. I tend to favor tall, upright pots in bold, monochrome colors or pleasing textures. low, broad pots can also be very attractive if you can find a sturdy plant stand to hold them. For succulents, I recommend planting in Black Gold® Natural & Organic Succulent and Cactus Potting Mix. It has excellent porosity and drainage as well as ample mineral components. If you prefer a little more organic matter, supplement with a bit of Black Gold® Peat Moss Plus, which is easily wetted and holds water well. The addition of a little peat is most useful with Sansevierias and Aloes.

Choose quality pots in bright colors, or muted TerraCotta tones, like these. Bottom drainage is essential.

The Best Bold, Sculptural Succulents

My preference is to purchase large plants from the start for instant gratification. They may cost a bit more, but they are worth it because many succulents are slow-growing. Here are some of my favorites for bold pots. Please make a note of those that have sharp tips or edges, because they are not safe for homes with small children or curious pets.

Agave

There are hundreds of Agave from which to choose as potted specimens. Each is unique and wonderful.

There are literally thousands of Agaves from which to choose,  and I love them all for their substantial rosettes of bold foliage. Some remain only a foot tall while others can reach 12 feet or more! Some have slender, needle-like leaves, such as the silvery Porcupine Century Plant (Agave striata ‘Live Wires’, Zones 7-10, 18 inches tall), while others have big, beefy, contorted leaves, like Twisted Tongue Hybrid Century Plant (Agave x amourifolia ‘Twisted Tongue’, Zones 7-10, 36 inches tall)–both of these are quite sharp. The sharp, tri-colored Joe Hoak Variegated Century Plant (Agave desmettiana ‘Joe Hoak’, tropical, 36 inches tall) is considered one of the finest variegated agaves. For an equally colorful, but softer agave, try Ray of Light (Agave attenuata ‘Ray of Light’, tropical, 36 inches tall), which produces big, voluptuous rosettes of bright green with fine ivory edges.

Aloe

Fan aloe has spectacular flowers and foliage. Flowers only appear on mature specimens that are several years old.

There are hundreds of aloes, and several are truly unique and wonderful. One that I recently ordered and await is the fantastic Swordfish Aloe (Aloe ‘Swordfish) with its wild, succulent, blue-green leaves edged in bright orange teeth. I plan to put it in a bright azure-blue pot for contrast. The tree-like aloe, fan aloe (Aloe plicatilis, tropical) can reach up to 8-feet when planted in the ground but stays much smaller in a pot. It looks much like a jade plant, but it has unusual fans of silvery blue leaves. Mature specimens will produce spikes of coral-red flowers in spring. The upright elegant aloe (Aloe elegans, image above) looks particularly lovely in upright containers that show off their form.

Mangave

Mangave ‘Bad Hair Day’ is a lovely (and funny) succulent for containers indoors or out. (Image by Jessie Keith)

Mangave are hybrids between the two succulents, Agave and Manfreda, and they make beautiful specimens for the home. Some are even hardy and suited to outdoor growing, particularly in more arid climates. Each year, more and more of these bold succulents are being offered. One of my favorites is the striking ‘Bad Hair Day‘ (Zones 7-11), which forms a rosette of cascading, purple-speckled leaves that fall down like a head of hair. The large ‘Blue Mammoth’ (Zones 7-11) is a larger form that reaches 2-feet high and a little wider when mature. Its undulating blue-green leaves look beautiful in either bright or equally muted pots. If you prefer variegated foliage, then Navajo Princess Mangave, which has bold, ivory-edged leaves that reach 20 inches, is an excellent choice. Plant

Sansevieria

Sansevierias large or small enliven indoor spaces with their flowing texture and appeal.

Snake plants or mother-in-law’s tongues (Sansevieria species and hybrids) are African natives with a well-earned reputation for being some of the toughest plants around. Not only do they grow well indirect light, but they withstand minimal water–two to three times monthly. They are also striking and attractive, especially those with long, variegated leaves. The long-leaved ‘Laurentii‘ is a classic variety with striated light and dark green leaves edged in yellow. The clumps slowly widen to form a sturdy, vertical specimen. ‘Moonshine’ has extra broad, pale silvery-green leaves that brighten up a room in the wintertime. The bright and beautiful ‘Gold Flame‘ has leaves with large vertical streaks of dark green and gold. These are just a few of the many snake plants available. You can’t go wrong with any of them.

Zanzibar Gem or ZZ Plant

ZZ plant (Zamioculcas zamiifolia) is another nearly indestructible house plant that adds color, texture, and interest to indoor spaces. It is commonly found in most house plant sections ar garden centers, so you should have no trouble finding it either. They can be quite slow-growing, so it is wise to start with a sizable specimen. Treat them as you would snake plant, and you will be gifted with lots of arching stems laden with glossy dark green leaves. The only thing that will kill a ZZ plant, aside from severe pests, is overwatering. So, refrain from giving it too much liquid care.

The durability and low-care status of these plants make them just as appealing to home gardeners. You might experience some problems with pests or diseases. If spotted, treat them right away.

Cool Succulent Hanging House Plants

Don’t underestimate the length and weight of some hanging succulents, like these donkey’s tails and string-or-dolphins. Over time, they can become quite weighty and substantial. (Note: These Vintage Italian Majolica Pottery Face Vessels are difficult to find but beautiful.)

Succulents have had a place in my home since I was in college. In fact, as life became busier and busier, I began to replace more tender, needy house plants with resilient succulents. By the time I had children, I only had succulent indoor plants. Then I realized that hanging succulents were even more convenient because they were out of reach from the kids and cats. They are beautiful and convenient if you have lots of windows that stream sunlight into your home. Some can even take the partial sun.

Another perk is that succulents lack the woes of average, needier hanging plants. They don’t need to be constantly watered and tended to due to higher exposure to the elements. Succulents are much slower to dry out and far more forgiving if the soil runs a little dry. The foliage will continue to look lush as long as you keep giving them a little care each week.

Hanging Succulent House Plant Care

 

Hanging succulents like these string of pearls and rattail cactus (far right) often look best if upgraded into prettier, more spacious pots once you bring them home.

All hanging baskets should drain well and be filled with a porous, well-drained potting mix that also holds moisture. Black Gold Waterhold Cocoblend or Black Gold Natural & Organic Ultra Coir are both excellent choices that are also OMRI Listed for organic gardening. Black Gold Moisture Supreme Container Mix is another good choice. To each of these mixes consider adding additional Black Gold Perlite to increase porosity and drainage. (Click here to learn more about repotting house plants.)

It is good for the health of any house plant to be taken outdoors during the frost-free growing months. Hang them along a bright porch or patio where they will get some protection from the high midday sun and strong winds. Regardless of their drought-tolerant status, they will still require weekly to twice-weekly water when outdoors. Light, slow-release fertilizer, and intermittent water-soluble fertilizer will encourage robust growth. They must be well-rooted and established in their baskets before they are fully tolerant of dry heat and winds, so keep a more watchful eye on new plantings.

When you take them indoors in fall as house plants, give them direct sunlight or bright filtered light. Water much less during the cold months–excess water can induce crown or root rot. Thorough water two to three times a month should be sufficient, depending on the plant, pot, temperature, and humidity. (Click here to learn more about winter succulent care.)

Securing Hanging House Plants

If you have a mantle and little inclination to secure hooks to your ceiling, place hanging plants along the edge. Tall, sturdy plant stands also work. Otherwise, hanging plants should be hung from hooks or brackets. Strong hangers and hooks hung over wooden rafters or securely mounted to a wooden ceiling beam are your safest options. Proper installation is key.

Choose a large, solid metal hook to mount in a ceiling joist (supporting beam) to hang a plant. Start with the basic materials: a step ladder, stud finder, pencil, and cordless drill set with the right bit (it should be a little smaller than the hook’s threaded shaft). Stud finders make it easy to find joists. Once you find the right spot, mark it with your pencil, and then drill a straight hole in the spot that is a little deeper than the length of the hook’s threaded shaft. Twist the hook’s base in until flush, and you’re done.

Hanging Succulents for Foliage

This variegated string-of-pearls shows the plant in full bloom.

Burros, Dolphins, Donkeys, Pearls, and Pickles: There are several senecios that are uniquely attractive. Each grows to great lengths–up to 3 feet or more–and has whimsical succulent strands.  Blue Pickle Vine (Senecio radicans ‘Glauca’) has strands of fun, blue-green, pickle-like leaves. String of Dolphins (Senecio peregrinus) is somewhat similar, but its curved fleshy leaves look almost dolphin-like. Burro’s Tail (Sedum morganianum ‘Burrito’) has dense strands of rounded, succulent leaves that look a bit like tails. Donkey’s tails are nearly identical, but the succulent leaves have sharper tips, and the stems tend to grow longer. Finally, Variegated String-of-Pearls (Senecio rowelianus ‘Variegatus’) is one of the easiest and prettiest succulent hanging plants to grow. Its grey-green stems are lined with round baubles of foliage with streaks of ivory and pink highlights. This one’s a little harder to come by, but Mountain Crest Gardens carries it often. Unusual white or lavender-pink flowers rarely appear on each of these plants.

Dancing bones has dense, slender, bone-like stems that produce tiny yellow flowers in winter.

Dancing Bones (Hatiora salicornioides) is a unique spineless cactus. Though delicate, yellow flowers often grace its stems, its glorious, mop-head of foliage is the main show. Grow it in a strong, sturdy hanging basket or tall container. Happy plants mature quickly and become large, so be sure you hang it from a strong hook secured to a beam.

String-of-turtles has unusual leaves that truly look like tiny turtle shells.

String-of-Turtles (Peperomia prostrata) has flattened, translucent leaves that look much like tiny turtle shells. In time, the plant will form a dense mat of dangling stems. This one can take a little less light.  On rare occasions, it may produce spikes of reddish-brown flowers that rise from the foliage.

String-of-hearts has silvery hearts touched with pink.

Variegated String-of-Hearts (Ceropegia woodii ‘Variegata’) has delicate, heart-shaped succulent leaves of silvery-white, pink, and dark green that dangle from the dark stems for an impressive show. It is one of the easier house plants that you can grow, and it does not disappoint when it comes to good looks.

Hanging Succulents for Flowers and Foliage

A chandelier plant in full bloom is a fine thing. (Image by David J. Stang)

Chandelier Plant (Kalanchoe manginii) becomes massive with age, so choose a substantial container from the start. Its dense stems have rounded succulent leaves. From late winter to early spring, copious orange to salmon-pink bells bloom for weeks. During the rest of the year, the lush foliage of this Madagascar native looks attractive. Thin out excessive older growth to encourage new.

 

Silvery white leaves and pink flowers make flower dust plant a very attractive choice for hanging baskets.

Flower Dust Plant (Kalanchoe pumila) has very bright silvery-white, almost dusty leaves that spill from any container or hanging basket. When this Madagascar native becomes laden with pretty pink flowers, it looks even prettier. Like chandelier plant, it flowers in late winter and spring.

The slender stems of rattail cactus become covered with flowers.

Rattail Cactus (Disocactus flagelliformis) develops long strands of finely-spined stems that cascade down to form a hair-like mop. Spectacular, large cactus flowers of pink, reddish-pink, or purplish-red appear from spring to summer. Prune off any excessive stems or those that become damaged or tangled.

Easy to Propagate and Share

Here the leaves of Sedum morganianum have rooted and developed plantlets on a porous base of potting mix.

Most succulents and cacti can be propagated from leaf or stem cuttings. The rarer your plant, the more you will want to propagate it for gifting and friends. Here is what you will need to take stem or leaf cuttings from your hanging succulents.

Materials

  1. Succulents
  2. Sharp knife
  3. Shallow pots with bottom saucers/tray
  4. Perlite or porous growing mix
  5. Grow lights or a bright window
  6. Rooting hormone with an anti-fungal additive (optional)

Use a sharp knife to gently cut healthy leaves from the stem. Dip the bases of the leaves, or a stem tip, into rooting hormone; rooting hormone hastens the rooting process and reduces rot but is not necessary. Gently moisten the perlite or potting mix in your shallow pots, and nestle the bases of the leaves into the mix. Place the pots in a spot with bright, filtered light and keep the perlite or mix lightly moist to almost dry. Over a matter of weeks, the bases will root and small plantlets will appear. You can pot them up once they have several leaflets.

How To Repot House Plants in Six Steps

Your once beautiful house plant has begun to look stressed. Maybe it’s lost some leaves, quit growing, needs more frequent watering, and has visible roots on the soil surface. Then you remember that it’s been three years since you repotted it…That means it’s time to upgrade its container home to improve better growth and overall appearance.

General House Plant Repotting Notes

All of these plants need to be repotted. To save money, I plan to pot the aloe in the red pot of the Ming fern asparagus. (Image by Jessie Keith)

Different plants have different potting needs–cacti need excellent drainage, most orchids grow best in bark, and hanging baskets like moisture-holding mixes–but there are also a lot of general requirements. Unless you are growing aquatic plants, all potted plants need pots and soils that drain well. Good light is required, so know a plant’s light needs before you try to grow it in your home to make sure that you can support its needs. Supplemental light is an option, but it is never as good as natural light. All potted plants require fertilization at different levels with different foods. When growth ramps up, all plants need more water, and when growth slows down, all plants need less water.

Pick the right-sized pot with drainage holes and a saucer to catch water. I like thick. heavy ceramic pots that last for years. (Image by Jessie Keith)

Finally, repotting is best done in spring, before house plants do most of their active growing, or in late summer to fall when they can grow a little before winter. I find that most house plants grow best if brought outdoors in summer. Just be sure to clean them up well before bringing them back inside before frost. (Click here to learn how to clean plants before bringing them indoors.)

Repotting House Plants in Six Steps

Good repotting technique is done in six easy steps. You just need a new pot, fresh potting soil, fertilizer, water, gloves, and pruning shears.

After cleaning the red pot, and preparing my potting soils, my aloe is ready to pot! (Image by Jessie Keith)
  1. Pick Your Pot: Select something beautiful that you will want in your home for the long haul. There is no reason to have plain plastic pots when you can have elegant ceramic ones Pick pots that are 2 to 6 inches bigger than the original. Small, slow-growing plants need pots that are just a bit bigger, and large, fast-growing plants need larger pots. Deep-rooted plants need deeper pots and shallow-rooted plants need shallow pots. All containers should have good drainage holes unless you are growing an aquatic plant. (Click here to learn how to plant potted water lilies.) Fast drainage encourages water flow and aeration, which roots need. Pick a sturdy saucer to catch water. Water-impermeable pots, like resin, grazed ceramic, or stone, hold water better. Pots made of TerraCotta and cement are porous and lose water more quickly. If you inherit a pot with no drainage holes, drill holes in the bottom with a pointed drill bit. (Be sure to wear gloves and safety goggles.)

  2. Pick Your Soil: Common house plants grow well in any good-quality, all-purpose potting mix, such as Black Gold All Purpose Potting Mix or Natural & Organic Potting Mix. Some plants, like African violets, cacti & succulents, or terrestrial orchids need specialty mixes with different levels of drainage and water-holding capacity.  That’s why we make Black Gold African Violet, Cactus and Succulent, and Orchid Mix. Hanging baskets need extra moisture, so we recommend mixes with high water retention, like Black Gold Natural & Organic Ultra Coir or Waterhold Cocoblend. All of our soils are natural & organic, and many are OMRI Listed for organic gardening.

    The roots of this Aloe were pot-bound but have been slightly loosened for better growth in the new pot. (Image by Jessie Keith)
  3. Prune Shoots and Unbind Roots: Remove any dead or unwanted stems and loosen any intertwined (pot-bound) roots, so they will grow well into the new pot and mix. Gently tease tightly-bound roots apart. If they are very dense, make cuts along the base and loosen the roots along the cuts. If your plants look good and their roots are not tightly bound, then bypass this step.

    The aloe is being planted in 1/2 Black Gold Cactus Mix and 1/2 Black Gold Natural & Organic Potting Mix. Provide enough soil to leave a 1-2 inch space at the top for watering. (Image by Jessie Keith)
  4. Repot: Remind yourself to leave at least 1-2 inches at the top for water. Place screen or a few pebbles over the bottom holes to hold soil (not necessary for my red pot with a built-in saucer and side drainage holes). Then add a layer of soil at the bottom. Place the plant in the pot and center it. Make sure it is not too high or low. Add mix to the sides and gently pack it in for good root-to-soil contact. Make sure there are no holes in the soil. Level the top, and add any decorative pebbles, moss, or shells along the soil, if you like.

    Lightly pack the soil along the sides. This is a good time to add slow-release fertilizer. (Image by Jessie Keith)
  5. Water: Use a watering can to gently water until all the soil is saturated and water fills the bottom saucer. In general, rewater when the soil is dry down to a knuckle’s depth. (Click here for a detailed article about how to water house plants.)
  6. Fertilize: Pick a fertilizer that’s well-matched to your plant. There are many specialty types for orchids, succulents, and foliage plants. Be sure to follow the product instructions. I like using slow-release fertilizer, such as Proven Winners Continuous Release Plant Food.
Topdress with shells of pebbles, if you like, water the plant in, and it is potted! (Image by Jessie Keith)

Newly potted house plants will not produce new top growth until they set new roots, so give them extra good care and a little time. Very soon they will be growing happily as if they had never had a problem in the first place.
