CONTAINER GARDENS MADE FOR THE SHADE

We all seem to have that dark corner of our garden or porch that looks uninviting, cold, and in major need of color. Have no fear—Janet Loughrey offers solutions for livening up that shady area, including insights into the best plant combinations that will thrive in low light.

Nearly every gardener has experienced the problem of too much shade, which can cause plants to become too leggy or fail to thrive. Whether it's a wooded suburban lot or a north-facing apartment balcony, low light means more growing challenges. Rather than being problematic, these dark areas can be viewed as an opportunity.

Pots in this shaded entry garden are grouped together for greater impact. Phyllostachys nigra (black bamboo), offers structure and height. Other plants include ‘Kong’, ‘Sedona’ and ‘Chocolate Mint’ coleus, ‘Mardi Gras’ and ‘Margarita’ sweet potato vines, and ‘Bonfire’ begonia. (Photo by: Janet Loughrey. Design by: JJ De Sousa.)

Adding containers to shady spots is a practical way to optimize these spaces. By using brightly colored or shiny metal pots, combined with lighter or contrasting hues of foliage and flowers, these decorative arrangements can brighten up even the darkest corner of a porch, deck, or entryway.

The emphasis is on woodland foliage, with hart’s tongue and deer ferns, moss, and native sedums. A small hellebore and Hosta ‘Tiny Mice’ complete this serene combination. (Photo by: Janet Loughrey.

Choosing the right plants is essential to successful shade gardening. Woodland natives, ferns, and hostas are just a few plants that prefer lower light levels. Many garden specimens will thrive equally well in containers, given the right conditions. A single plant, such as Japanese maple or bamboo, can be just as compelling as a combination.

For shade containers, Vina Winters chooses a foliage specimen such as Hypoestes (polka dot plant) and pairs it with a similarly hued flower such as tuberous begonia. Soft shield and maidenhair ferns provide contrasting texture and shape. (Photo by: Janet Loughrey. Design by: Vina Winters.)

Plants with attractive foliage offer reliable season-long color. Coleus are workhorses of the shade garden, with a nearly endless array of colors. Other reliable foliage standbys include Japanese painted fern, sweet potato vine, and Rex begonias.

An underutilized alternative to annual bedding impatiens is Torenia (wishbone flower), which blooms consistently over several months in colors of blue, purple, pink, and yellow. Other prolific bloomers include fuchsias and begonias such as ‘Bonfire’.

Optimal growing conditions are essential to healthy shade container plantings. Landscape designer Lucy Hardiman uses high-quality potting soil, replenishing it annually. She mixes a time-release fertilizer into the top several inches of soil before planting. Because containers need frequent watering during hot summer months, nutrients quickly leach out of the soil. In midsummer, Hardiman supplements with a water-soluble bloom booster fertilizer every other week.

There are no hard and fast rules to mixing and matching plants for shade containers. Breaking the rules can result in some unexpectedly delightful surprises.

Organic Container Gardening Tips

Growing plants in containers can be the perfect solution for gardeners with limited space. But even if you have an abundant in-ground garden, you might appreciate the flexibility of growing organic plants in pots.

Brighten up a patio or deck with colorful flowers, grow your own vegetables, or create a rooftop garden. You can move the pots around to capture the sunlight and move them to the shade when it gets too hot. Hailstorm? No problem — just move the containers inside.

For people who live near wildlife, like Debbie Christopher of Estes Park, Colo., growing in containers may be the only way to maintain a garden. “The deer and elk like to visit our yard and eat everything in sight,” she says. “Growing plants in pots on our enclosed deck is the only way we can enjoy a garden.”

Type of container

Most nurseries offer a huge selection of terracotta, ceramic and plastic pots, but container gardening also offers the perfect opportunity to recycle something from the garage or basement. Watering cans, spatterware bowls, buckets, kitchen canisters, vintage cowboy boots, tires and even an old footed bathtub can all be used as planters.

You’ll want to consider how much weather the pot can handle; an old can that is prone to rust wouldn’t be appropriate in a rainy climate, for instance. Also, consider the size of plantings you’ll be adding; If you are going to grow vegetables, for example, the pot will need to be large enough to hold plenty of water and allow roots to develop.

“Beware of decorative planters that lack drainage holes,” says John Pohly, Colorado State University Extension Horticulturist. “This creates water-logged soil and rotting roots. Research shows that the old practice of placing a layer of gravel in the bottom of the container, to give some room for water to accumulate without saturating the soil, doesn't really work. If you want to use a decorative planter that doesn't have a drain hole, put your plants in a regular flower pot and place that inside the decorative container.”

Depending on what material the container is made of, you may also be able to drill or punch holes in the bottom of it. You can also recycle a used plastic milk jug or soda bottle as a pot liner; just punch drainage holes in the bottom with a nail.

Growing medium

You can buy special organic container mix at many garden centers, or you can make your own by amending dirt from your garden for container gardening; simply mix together one part garden soil, one part compost and one part sand. You may also want to add some peat moss, which will help the mixture hold water. To improve drainage you can also add organic perlite, which lightens the soil mixture and has a neutral pH.

What to plant

People grow nearly every plant under the sun in containers. Most annual flowers are well suited for organic container gardening, and their long blooming season makes them ideal candidates for pots.

You can also successfully grow many vegetables in containers; just remember that most will grow best with about six hours of sunlight a day so you’ll need to place them in a fairly sunny location. Look for special dwarf varieties of tomatoes developed just for patios, and compact cherry tomatoes and peppers are also good choices for container gardens.

Lettuce, greens, spinach, herbs, onions and carrots all grow well in pots. If you provide a trellis or vertical support, you can also grow trailing vegetables like beans, peas and cucumbers.

More tips for success

PLANTING: Just before planting, wet the soil mix well; you can do this in a bucket or wheelbarrow, or you can even add water to the bag if you’re using a premixed organic potting soil. Arrange the plants in the pot, add the soil around them, and gently pat it down around the plants. Don’t fill the soil too close to the top of the pot; you want to be able to soak the plants well without water overflowing.

WATERING: Most container plantings tend to dry out quickly and will need very regular watering; during hot spells they may even need to be watered twice a day. Hanging baskets are especially prone to evaporation and should be watered until the water runs out of the bottom of the pot; wait until the soil is barely dry to water again.

During extreme heat or a weekend away you can temporarily put the pots in a tray with standing water, but don’t leave them longer than a day or two or the roots may rot.

FERTILIZING: Flowers and vegetables grown in containers will benefit from regular feeding throughout the growing season. With their promises of giant crops and big blooms, it may be tempting to use nonorganic bagged potting soil mixes and commercial fertilizers, but it’s just as easy to utilize organic growing techniques with container gardening and reap the benefits of pesticide- and chemical-free vegetables and naturally grown flowers and plants.

There are many organic fertilizers available that can safely be used on container plantings; many are fish- or compost-based. Worm castings are also an excellent organic fertilizer for container plants and they are good for indoor houseplants as well, since the mixture is relatively odor-free.

CONTROLLING PESTS: Troublesome insects are a fact of life when gardening. Since garden bugs do the most damage when plants are stressed or starting to wilt, be sure to keep them well watered. The best way to rid plants of pests like aphids is just to remove the pests with your hands. You can also move the container to your kitchen sink and use your water sprayer to spray the plants — especially under the leaves — to remove bugs.

If you have a large infestation, mix equal parts of water and liquid detergent in a spray bottle and spray the bugs. There are also commercial organic pest sprays you can buy; it’s best to apply these mixtures in the cool of the evening rather than in the hot sunshine when they can damage delicate foliage.

MAINTENANCE: Deadheading will keep flowers looking fresh, and removing dead leaves will help control bugs. One of the best aspects of container gardening is its forgiving nature; if a plant isn’t thriving or starts to wither, you can use a garden spade to carefully remove it and simply plant something else in its place.
