Most homeowners don’t think about the problems trees could have before they buy them. They base their decision on the tree’s aesthetics and what’s available at the nursery. However, many popular tree and shrub species in Northern VA are prone to diseases and insect attacks. Planting a tree or shrub species that is known to have lots of problems can cost you a lot of money in preventative care and maintenance. If you’re looking to plant a new tree or shrub this spring our arborists suggest you opt for a species that are considered problem free. To help you out, our Arborists have compiled a list of trees and shrubs that have very little to no issues with common diseases and insects in the area.

In fall, the Kousa Dogwood’s leaves turn a beautiful purple and scarlet adding intense color to your landscape.

This medium to large tree has a wide growth habit and sports attractive mottled bark. In the fall, the Persian Parrotia has showy foliage color which varies from yellow to orange to purple. It prefers well drained, slightly acidic soils and full sun but will still do well in light shade. The best aspect of the Persian parrotia is that it is disease-free and can withstand drought, heat, wind, and cold temperatures.
8. Lacebark Elm (Ulmus parvifolia)
Native to Eastern Asia, this species has become a popular landscape tree. This medium sized tree, is valued for its shiny, dark green foliage, rounded shape, and multiple colors/textures of its bark, hence its name. In contrast to the American Elm (U. americana), the Lacebark Elm is resistant to Dutch Elm disease, elm leaf beetle, and Japanese beetle, all of which cause significant damage to other elm species.

10. Southern Magnolia (Magnolia grandiflora)
Native to the Eastern United States, the Southern Magnolia and various species of other magnolias tend to be disease-free. This large tree produces large, showy, fragrant, cream-white flowers in June. This species tolerates high soil moisture; however, depending on location it needs protection from winter winds to avoid leaf scorch. If wind and cold is an issue there are several cold-hardy cultivars, such as ‘Edith Bogue’ and ‘Bracken’s Brown Beauty’. Other disease and pest resistant Magnolias include the Star Magnolia (M. stellata), the Saucer Magnolia (Magnolia xsoulangeana), and the Sweetbay Magnolia (M. virginiana).
