Your trees and shrubs face many challenges to remain healthy year-round. Environmental conditions, disease, fungus and insects can threaten the health of your plants. Some common insects found on trees and shrubs in our area this time of year include lace bugs and aphids. But proper identification, and preventative and curative treatments can protect your landscape investment. Let’s dive deeper.
Lace bugs are common pests found on azaleas, rhododendrons, sycamore, broad-leaved evergreens and many deciduous trees and shrubs. Though in small numbers they cause no real harm, they can be a major problem when present in high numbers.
Lace bugs are about 1/8 of an inch long, bronze in color and have transparent wings held flat on their backs. Nymphs are black. Both adults and nymphs are always found on the underside of leaves of infected shrubs and cause damage by sucking the chlorophyll from the plant. Their damage causes the leaves to be bleached or bronzed instead of green and causes the plants to poorly grow or bloom.
To avoid excessive lace bug damage to your plants, make it a point to regularly check the undersides of plant leaves for their presence. If you have severe damage, it can take some time for the plants to recover.
Aphids are small, soft-bodied insects that attack plants by using a piercing and sucking mouthpart to suck “juices” from the plant. They tend to congregate on the new growth and underside of leaves where they will grow in large numbers over time. Aphids may be winged or wingless, measure 1/16 to 1/8 of an inch long and can be green, yellow, orange, red, black or white in color.
Aphids excrete a sweet, sticky honeydew which attracts ants and can cause sooty mold to develop. They are commonly found on roses, crepe myrtles, viburnums, euonymus, hawthorns and pines, just to name a few.
Scale and aphids, among other insects, can not only be a nuisance, but can cause damage to your plants. Professional Tree & Shrub Care is an important service to ensure healthy plants and blooms.
