Protect Your Trees & Shrubs from Winter Burn

Did you know trees and shrubs can become dehydrated just like you? 

You might have noticed a few evergreens and shrubs turning brown last winter. This damage, called winter burn, can affect many outdoor trees and plants including Arborvitae, Boxwood, Yew, Rhododendron and Holly.

Some people believe winter burn is caused by cold temperatures. While this is somewhat true, winter burn actually occurs because of drying, specifically when water evaporates from needles and leaves. When the plant gets energy from the sun through photosynthesis, water is released. But when the ground is too dry or frozen, the plant can’t replenish its water supply, which causes dehydration and can lead to winter burn.

Luckily, you can prevent this from happening in your yard with the help of Wilt Stop, which helps keep trees and shrubs from drying out. By applying Wilt Stop twice during the fall, you can inhibit the development of winter burn. Here are a few tips when using Wilt Stop:

  • Apply Wilt Stop once in mid-to-late October and again 30 days later in November.
  • Only spray Wilt Stop when temperatures are 40 degrees or above.
  • Make sure the ground remains moist until it freezes.
  • Continue watering trees weekly until the ground completely freezes.
  • Mulch around the plant to help retain moisture.
  • Cover both the top and bottom of leaves until they begin to drip.
  • If thawing occurs mid-winter, water the plant to keep the roots moist.

Using these tips to avoid winter burn, your trees and shrubs should be winter-ready and look great next Spring. For more tips on winterizing plants, visit our Seasonal Garden Maintenance Calendar.


Remember, trees and shrubs need care year-round and are susceptible to dehydration just like you. If you have these plants, stop by your nearest Earl May Garden Center to pick up your bottle of Wilt Stop today!
