Poorly dwarf apple tree
I uncovered a dwarf apple tree, last year growing amongst brambles on the allotment. It's about 3ft tall, variety unknown. Sorry, I don't have pics. It was given a good mulch of muck in the spring and left to fruit/grow. It only produced one apple which has black spots, as do the leaves. I planted new fruit tree's near by, these are healthy. Q is...what's wrong with the apple tree...can it be treated or would it be better to replace it? What I don't want to happen is if I keep it, the healthy fruit tree's will develop the same problem and I'll loose them all.
