Question From: B. Lesesne - Myrtle Beach, South Carolina, United States
Q: Our 20 year old River Birch is a clump of 4 trees. It seems healthy except my husband is very concerned that where they come together at the bottom of the clump of trunks, the area holds water and forms a sort of 8 inch deep hole. He is concerned the area may rot and one of the four clumps will easily fall in a storm. He wants to put cement or foam or something similar in the area. I think that may rot it and I say leave the tree alone. What do you think? Do we have a hazard on our hands most likely or unlikely? Thank you so much.
Cementing or using foam is not a good Idea. You need the advice of a professional. I recommend you get an on-site inspection by a certified arborist. To find one in your are go to www.tcia.org and enter your zip code. Best And Happy Yardening, Nancy
