Affected plants may appear normal and resume growth in the spring, only to weaken or die in late spring or early summer because the amount of new growth produced is greater than the weakened root system can support. Lawn grasses also are prone to winter damage. Newly established lawns, whether they are started with seed or sod, are especially susceptible to damage in dry weather. Pay particular attention to turf on south exposures.
If you have any questions or comments about how to ensure the survival of your landscape plants, shrubs and trees, give us a call at 827-5296 and ask for Tim, our residential landscape specialist.Trees and shrubs at risk from dry winters include recent transplants, evergreens and shallow rooted species such as lindens, birches, and Norway and silver maples. Evergreen shrubs, particularly those growing near a house, may suffer root system damage during dry spells.
Water during winter only when air temp is above freezing.In the future, you should plan onwatering plants when the leaves start to fall in the autumn. This will send them into winter with adequate soil moisture. For recent transplants, a soil needle or deep-root-feeder can be used on low water pressure for one minute at each site to water the root ball and surrounding soil.
Water during winter only when air temperature is above freezing. Apply water early in the day, so it will have time to soak in before nighttime freezing. If water stands around the base of a tree, it can freeze and damage the bark.
In most years, one or two winter waterings will be enough to keep plants from suffering winter damage.
