Nectarine tree: mites, ants, leaf curl, stunted growth.
I planted a dwarf nectarine tree a couple months ago and it's showing some problems. There are lots of ants crawling up the trunk and all over the leaves. There are what appear to be black/grey mites on many of the new leaves which are curled and drying out. The ants and mites seem to be working together. I've been spraying off the ants and mites with water but they keep coming back.
The tree also seems like it should have grown more by now. At this point, it is still just under 2 feet high with just some additional leaves which are the curled ones. The tree was planted with a mix of native clay soil, some compost and a potting soil blend. Any ideas on how I can save it? Thanks!
