Q.Japanese Maple Winter Damage.

Zone Kettering UK | Sugar Maple added on May 13, 2021 | Answered

We have a beautiful Beni Maiko acer in a pot in our garden. When winter started it was moved from its usual prominent position in the centre of the garden to a sheltered spot between two house walls, we covered it as we usually do in the winter and protected the pot. Much to our alarm when we took off the covers to put it back in its usual spot we found that its bark appears to have been stripped by the frost, but on closer inspection it is more like something over the top of the bark. Enclosed are photographs of the winter damage for your advice please. We want to know how to treat it and how serious it is. Thank you.

That tree does not need winter protection. It will survive down to our USDA zone 5. In your country, there is not any place that gets that cold. Therefore, it will do more damage to cover your tree for the winter, than it will to let it go, naturally.

I would use a fungicide, and when next winter comes around it would be wise to let it acclimate, naturally.
