Columnar Aspen
Gardening Question From Barb:
I have a group of columnar aspens in my yard and this year they have grown huge leaves at the very top. The leaves are easily 5 times larger than the other leaves and have appeared only on the new growth. The trees are bent over on the top due to the weight of these monster leaves. Why did this happen? Should I prune that new growth off to avoid this problem next year? I live in Edmonton, Alberta, Canada.
Answer From Pat:
Large leaves on the top of aspens are natural to this species of tree and apparently nothing can be done about it. Here is a link that explains the phenomenon: http://forums.
