Lychee tree problems
I'm having trouble with my lychee tree. It has leaf tip burn, lots of leaf notcher weevil damage (this I know about and am now controlling), but also a strange black speckle on leaves, some leaves are turning red, new growth is often distorted and black at the tips, and it seems to lose a lot of leaves when I shake it to collect the weevils.
Any idea what's wrong? Thanks!
