Gardening in the Shade

    • Marigolds are prolific bloomers that will add bright orange, yellow, mahogony and crimson to your sunny flower beds.
    • Prune rhododendrons, camellias and azaleas to shape them now. If you wait much longer, you will be cutting off next year’s flowers.
    • Remove suckers on rose bushes. These vigorous canes emerge from below the bud union and should be cut off as far down as possible.
    • Feed annual blooming plants and hanging baskets every two weeks for prolific bloom. Keep dead flowers pinched off.
    • Start seeds of broccoli, cabbage, cauliflower and other cool-season crops now. Transplant them to the garden next month and they will be producing for you this fall.

Gardening in the Shade

When the weather is too hot for working in the sun, gardening in the shade is much more pleasant. While some plants do not grow well in low light, many others thrive in these conditions. Just as moisture, temperature, and soil conditions may limit plant growth, the amount of shade present may determine which plants will grow successfully. The key is to discover which ones are adapted to the conditions in your yard or garden.

Landscapes change their degree of shade over time. As trees and shrubs mature, the landscape receives greater shade. What was once a sunny garden may evolve into a shady one.

Keep in mind that light patterns also change with the seasons. An area that is in full sun in summer when the sun is high in the sky may have medium shade in spring and fall, when the sun is at a lower angle. Also a shady summer area may receive more sun in the winter when the leaves fall. Study your garden through the seasons to accurately determine what type of shade is present.

Available sunlight may be increased by selective pruning. Removal of lower limbs on large trees can increase light levels significantly. Large shade trees are a valuable resource that in most cases should be preserved. However, removal of diseased, unattractive, or poorly placed trees improves the beauty of your property and increases the light available for plant growth.

Plants growing in the shade often must also compete with roots of shading trees for nutrients and moisture. Shallow rooted trees such as large maples, birch trees, redwoods, poplars, pines and willows are particularly troublesome. Roots competing for limited surface water may cause shade gardens to dry out more quickly than expected.

Adding organic matter to shade garden soils will help. Most woodland species are accustomed to growing in soils rich in leaf litter compost. Raking and removal of leaves each fall in the typical landscape disrupts this natural nutrient recycling process. If you are patient, earthworms will eventually incorporate organic matter into the soil.

Bright, bold colors are less common in shade tolerant plants than in sun-loving ones. Flowers are usually produced less abundantly in the shade as well. For these reasons, shade gardens are often more subtle and restful than sunny ones.

Plant textures become more important elements of the design. Large-leaved plants such as hostas have a coarse texture, while finely divided fern fronds create a fine texture. Strong contrasts in texture will help individual plants stand out.

Glossy leaves have more impact than dull or velvety ones. Variegated or yellow-green foliage is evident in the shade more than dark green or blue-green foliage. Light colors – white, cream, yellow and pastel pink – stand out in the shade, while deep reds, blues and purples may fade into the shade unless set off by a contrasting lighter color. To emphasize plantings in the shade, concentrate on plants with light-colored flowers or foliage.

Impatiens, begonias and coleus are by far the most successful flowering annuals for a wide range of shade conditions. Bedding or wax begonias come in pink, red or white with green or dark purple leaves. A spectacular sight is a bed or border of impatiens edged with wax begonias in a contrasting color. The color range for impatiens includes red, pink, white, orange, orchid and bi-colors. Plant a large-leafed Kong Coleus to the background and you’ll have a stunning display.

Add a fountain or birdbath and you will enjoy your shade garden all through the hot days of summer.
