Q: During a heavy rain my Leyland cypress fell over. This has happened twice before. Each time, I anchored it with rope and thought roots would grow and stabilize the tree. What else should I do?
A: It’s hard to get a tree to stand up strongly after being blown over. The roots on one side are pulled from the soil and those on the other side are folded and kinked as the tree comes to rest on them. A tree can regenerate roots but it may take five years of staking before it is solidly anchored again. Leyland cypress anchors well only if the roots spread 5 – 10 feet in all directions from the trunk. The roots on your tree are so compromised that I’d deeply install a permanent anchor post one foot from the trunk and use a wide nylon strap to join the two.
