COMMON WEEDS & PESTS OF MARYLAND
Japanese Stiltgrass
Crabgrasses
This weed is an aggressive species resembling tiny bamboo. It is very invasive in lawns and needs repeated applications with special herbicides to limit its spread.
Several varieties of related annual grasses pop-up in our lawns over the summer and stifle our perennial species. Weed controls as well as dense turf are needed to manage them.
Wild Violets
Bagworms
A perennial broadleaf weed with a waxy leaf surface and vine-like root system that creeps throughout lawns. Special herbicides are usually required to control this weed.
Bagworms feed on weakened evergreens, and an infestation can kill a small tree in a single season. They can be controlled by an environmentally friendly spray in summer.
Beetles and Grubs
Emerald Ash Borer
As adults, they feed on our flowering trees and shrubs, especially cherries, plums, and roses. As grubs, they eat the roots of healthy turf. Both stages can be treated to prevent damage.
This invasive species has killed a large number of ash in our area, but there is are treatments that can prevent or minimize damage to susceptible trees.
