As winter approaches, plants should be thoroughly watered before the ground freezes to help ensure roots are well hydrated. Winter sun and winds can cause plants to lose moisture through foliage and thin bark stems. Water that is frozen in the soil is unavailable for root uptake to replace moisture loss, resulting in scorched foliage or dieback of woody tissue. While all plants can experience winter desiccation, evergreen plants are the most susceptible.
Evergreens exposed to south and west winter sun and winds may require additional protection. Temporary fabric or wooden screens, such as burlap or snow fencing, will reduce exposure and decrease the chances of winter burn. Liquid anti-desiccant sprays may also be helpful, but they can break down over time. Newly installed plants are especially susceptible as they may not have had time to develop a sufficient root system. Avoid using plastic screening as it can cause plants to heat up during the day, increasing the chances of drying and browning.
Finally, remove all leaves from groundcover plantings. Groundcovers such as pachysandra, myrtle, ivy and junipers are evergreen plants that require air and light to prevent disease development on the leaves and stems. Allowing leaves and other debris to remain atop groundcover plants may result in thin or dead areas next spring.
Just a little bit of effort now will help give your plants a healthy start next spring!
