Ants causing problems on Cherries?
I am still trying to figure out if it is disease or pests destroying the new growth on my 1st yr cherries. I have posted some pics before but so far havn't figure it out. The buds of the young leaves dry up and turn brown before they come out. The leaves that mature look healthy. There are 4 varieties in 1 huge raised bed. The utah Giant is doing well. The other 3 are in dire straits.
There has been these tiny red balls on the leaf stems. On some they are tan/yellow. After bird netting i noticed ants walking up and down limbs and doing something at those little nodules. I had seen these little nodules on cherry leaf stems before and thought they were normal.
BTW the utah G. has the little nodules too and it has been able to put up a canopy. Please help!
