Young oaks
Mar. 6th, 2020 12:03 pmThis winter has been unusually mild locally. The meteorologists says temperatures have been, on average, about 3 degrees Celsius above average. We have had some frost in the mornings, but rarely hard frost. We have not yet had to shovel snow.
Most of the trees lost their leaves in the fall as they normally do. This is the first year that I noticed most young oaks have wrinkled brown leaves that are still on the branches in March. The older oaks all seemed to lose their leaves.
Apparently, retention of dead material which plants normally shed called marcescence. It is a typical trait of young beech and oak trees to keep their leaves. Biologists are not sure why this happens.
