Colossal Chestnut Tree Has More Dead Limbs Than Usual This Spring

Question From: El Dorado Hills, California, United States
Q: I have a 20 year old colossal chestnut tree. As it has grown over the years the tree has suffered annually from branch or limb die back. The tree has filled in the gaps and grown normally. This year as it is leafing out it has produced many more dead limbs. I have searched the internet to see if this is normal. I still have not found the answer. Does my tree have a disease? Is it normal for colossal chestnut trees to have limbs die back to then be replaced by limb growth from the trunk?

A: If it were my tree I would have had it looked at by a tree doctor. Limb die back is never normal, but I live in Michigan. My guess is your tree has some sort of disease. If you value it I would have it looked at ASAP. To find a certified arborist in your area go to www.tcia.org and enter your zip code. Best And Happy Yardening, Nancy
