Q.Avocado tree leaf curl

Zone Uk | Gabriel8500 added on August 26, 2019 | Answered

I have this small avocado tree and I cut it down to 3 inches when it hit six, and then I went on vacation for 22 days and couldn’t cut the new growth down. I had someone water it but the leaves have started to curl under themselves. There are no signs of brown or black on them. What’s wrong?

It looks like the classic symptoms of overwatering, or a pH swing. These are definitely the early signs of root rot.

From here, you will need to treat with a fungicide, and provide the tree with full sun (meaning higher than window lighting can give) or at least 200 watts of horticultural lighting- Whichever is easier.
