Crape myrtles are called the lilacs of the south and
rightfully so. They look like lilacs, begin to bloom at
about the time the northern lilacs finish their spring
displays and have lilac-like colors. All that is really
missing is the fragrance. Even though we are familiar
with crape myrtles many questions do arise.
Someone always feels they are being left out of the
neighborhood display at least for a while. A common
question is why isn't my crape myrtle in bloom? Well,
not all crape myrtles bloom at the same time as there
are many different varieties. Also have you noticed
crape myrtles near the street lights are some of the
first to bloom. They are influenced by the length of the
day and street lights can extend the day to bring them
into flower. Crape myrtle receiving some shade and those
that have been heavily pruned may also be the last to
bloom.
Sometimes it is a little scary and many
gardeners want to know why the bark is peeling. This is
natural and it's the plants way of renewing the outer
layer. When the bark peels it helps remove unwanted
moss, lichens and sometimes insect pests. Often the
inner layer of new bark is a creamy to cinnamon color
gardeners enjoy.
Here is another question
gardeners ask. Can crape myrtles be pruned at this time
of the year? Many practice removing the seed pods formed
during the summer by cutting the stems back to about the
thickness of a pencil or larger. This encourages new
growth and more blooms. This type of pruning can be
continued through early September. Suckers from the base
can be removed as well as entangle limbs and shoots
growing out of control.
One final question is
what care is needed during the summer? Crape myrtles are
drought tolerant but grow best in a moist soil. So, if
you want growth and good flowering water when the rains
fail to provide adequate moisture. Plantings also like a
feeding in June and again in August. This keeps them
growing and flowering. Some gardeners also notice black
sooty mold on the leaves during the summer. This is due
to aphids or whiteflies feeding in the new growths. It
can be ignored or you could use an insecticidal soap or
horticultural oil spray to get all these pests under
control - just follow label instructions.
