I planted one apple tree 4 years ago. 2 years ago it produced apples. Last summer and this summer it did not produce any yet my neighbour who only planted 2 years ago had plenty of apples. This summer neither of us got any apples. I also planted 2 more trees last summer (one of them had apples when I planted it) yet this summer I did not get any apples on either of them. I live in Fort St John and I see lots of other apple trees that prodcued lots of apples this summmer. Would appreciate any suggestions or answers why I am getting no apples????? I have never pruned the trees. What time of the year should I prune them?
