Summer
Heathers

Heathers are low-growing, shrub-like perennials
that blossom into a sea of color. They look great planted with dwarf
conifers, especially when a variety of shapes, colors and textures
are used. Interplant late flowering varieties with deciduous plants
that have colorful foliage in the fall for a striking display, and
use them in
camellia and
rhododendron beds to add summer color. They are also used in
rock gardens and as groundcovers.
Heathers enjoy an sunny site
with good air circulation and an acid soil that doesn't dry out or
become waterlogged. Acid soil is a must for summer heathers, and if
your
pH is too high, you should amend with aluminum sulfate before
planting if necessary. Pale leaves and slow growth indicate that the
soil is not acid enough.
You can help the soil retain
moisture in the heat of summer by applying a
mulch. Two inches of bark chips or cocoa shells make a good mulch
for a bed of heathers.
Care and Maintenance
Use a fertilizer designed for acid-loving plants in
spring and at regular intervals through the growing season as the
package directs. It's best to use a soluble fertilizer rather than
one that has to be worked into the soil because the roots are very
shallow, and you can easily damage them by trying to cultivate
around the plants. To encourage strong growth, shear off the plants
in early spring before flowering begins.
Heathers are susceptible to
fungus, and if your summers are hot and humid, you may want to have
a
fungicide on hand so you can treat your plants at the first
sign of infection.
Taking Cuttings
The best time to propagate heathers is mid- to late
summer. Fill a pot with a mixture of half sand and half sterile peat
moss, and make holes for your cuttings with a thin twig.
Clip a 1-1/2 inch piece from
the tip of a non-flowering shoot. Make sure the shoot is from the
current season's growth. Strip the foliage from the lower half of
the stem with your fingers, taking care not to damage the stem, and
dip the lower end of the stem in rooting hormone. Make sure the
rooting hormone covers the part of the stem where you have removed
the foliage, then tap gently to remove the excess.
Place the cuttings in the
holes that you have prepared and water the pot thoroughly but gently
so as not to disturb the cuttings. Once the pot has drained, cover
it with a plastic bag, making sure the sides of the bag don't touch
your plants. If necessary, insert a few twigs in the soil to hold
the bag away from the plants. Leave the bag in place for 6-8
weeks.
