How to Treat & Prevent Crepe Myrtle Bark Scale

Crepe Myrtle bark scale has become a real issue in Hampton Roads, affecting our beloved Crepe Myrtle tree. Virginia has now joined the ranks of 12 other states in which this insect is unfortunately found.

Large infestations are easy to identify, as this is the only bark scale in the U.S that impacts crapemyrtles. Not to be confused with a heavy aphid infestation, crepe myrtle bark scale will also result in the occurrence of black sooty mold on the surface of the tree’s bark. Other identifying factors include small, Q-tip like white/light gray spots on trunks and small twigs, which are actually part of the female insect, under which the pupae grow. To treat, we recommend Fertilome Systemic Insect Drench.

Sweet Alysum, The Go-To Plant for Every Garden

An old-time favorite, sweet alyssum (also known as lobularia, pronounced lob-u-larry-uh), features an incredibly long blooming season from late spring to frost. This fabulous little plant is low maintenance, drought tolerant and produces a profusion of wonderfully scented flowers that will quickly cover beds and borders with a blanket of flowers that mix easily with other annuals and perennials. White is the most planted color, but it is available in pink, purple and apricot. The bright white pairs well with lots of other springtime favorites like bush daisy, candytuft and petunias and is gorgeous spilling out of window boxes, hanging baskets, or combination plantings. This annual grows best in full sun and cooler weather, however, it will tolerate partial shade and can survive light frosts.

Be sure to check out Lobularia, Frosty Knight®, from Proven Winners, a new hybrid that is much improved over the old seed varieties. Frosty Knight® features white flowers with variegated green and yellow foliage that provides color interest even when the flowers are not in bloom. Fragrant, just like the traditional alyssum, this one tolerates a wider range of temperatures - taking the heat and holding up much better in summer unlike traditional lobularia that just like it cool. It’s a good-sized, vigorous grower - getting up to 24-36" wide, making it a great filler in hanging baskets and patio pots. And, it does not require dead heading! Prefers full sun to partial shade.


High-Voltage Color, Pericallis

Pericallis produces a plethora of large daisy-like blooms in a unique, high-voltage color spectrum of blues and violets. These dynamite plants love cool, wet weather making them a perfect choice for early spring. The leaves are heart-shaped and range from medium to dark green. The center of the foliage is home to a rounded cluster of daisy blossoms that are a deep, blue-purple to magenta with petal bases being white around the central eye of the flower. Try planting them in the garden or in large patio containers to add vivid color in spring. Plant in full to part-sun locations.

And, be sure to check out Pericallis Primavera™Blueberry. Bred in Israel, this variety brings good heat tolerance compared to the competition. As with other pericallis, its tolerance of cool temperatures makes it an excellent choice for early, cool-season color. Its compact habit and continuous flowering is well suited in large containers and gardens.
