What can I do to protect my delicate trees and shrubs this winter?
The Lower Tidewater region is unique because we enjoy warm summer weather that is ideal for tropical trees and succulents. Unfortunately, we can also experience harsh winter temperatures and high winds that can severely damage tender plants. Wrapping palms and other tropical trees in plastic sheeting is NOT advised in our specific area, because the winter temperature fluctuations can cause condensation inside the plastic, which can lead to rot and specific types of fungus. Our tree and shrub care expert, Dave Planelles, recommends applying an anti-transpirant product such as AquaLock to any ornamental plants that are susceptible to winter burn, because it protects by forming a “thin, flexible, water-repellent layer on plant surfaces” to insulate and prevent damage.
Other recommendations from Dave to keep your shrubs healthy this winter, include keeping the mulch level around the base of the plant at NO MORE than TWO inches deep. If the mulch layer is too thick, it may cause harm to the plant by preventing proper nutrients from being absorbed, and can (in some cases) suffocate the plant. In our region, two inches of mulch is more than enough to insulate and protect the roots and retain the right amount of moisture. Dave also recommends considering a light application of a low-nitrogen, organic 3-4-3 product, such as our “Replenish” top dressing compost fertilizer to help gently feed roots over the winter. If there are disease/pest concerns, having an application of dormant horticultural oil will help to smother any lingering scale bugs and their eggs, as well as protect against diseases like blight on new growth in early spring.
Over the next two weeks, Dave will begin applications for customers who purchase an AquaLock treatment for their delicate ornamentals. If you’d like an estimate for the cost of an AquaLock treatment for your at-risk shrubs and trees this winter, or for more information on Dave’s Annual Tree & Shrub Program, please contact our office and Dave will be happy to stop by to evaluate and quote pricing for you!
