The avocado trees look terrible and it happened all of a sudden. Well not really, but we have had a warm winter and in the right spots, the trees are beginning to baalllooon with flowers. They look kinda ragged at this time, even when they are in good health. Add a little bit of Persea mite damage to a young tree, with some leaf drop, a little bit of root rot and they look a bit haggard. This is a hopeful time, when you can start expecting to see some fruit set and possible prospects for good yields. Make sure they are getting the water they need, that their roots are in good health and maybe a little bit of nitrogen depending on the fall leaf analysis.
