Our Maple got sun scald about 8 yrs ago when it was younger and when I didn't realize what it was. It's got a pretty big scald but has been healing in on the edges. Will it heal all the way shut? Doesn't look like its did much in the last couple of years. Also, I've been covering it every winter with a white plastic tree guard. Should I continue to do so? Thanks. DeeDee
The wounds may close but there is nothing that can be done about the damage that has been done. A few things can be done to try to protect the tree from more damage. The extent of damage is dependent on the weather. Watering, mulching, tree wrap help. Tree wraps also cause problems so it is important to install it properly and remove it in the spring.
