Stone fruits can be affected by fruit moths, aphids, leaf curls, brown rot, shot holes, cankerworms and rust. We recommend applying a pruning paste to seal the damage and prevent infection if you remove larger limbs. Therefore, we recommend pruning in autumn to avoid the spread of pests and diseases.
Although, it’s not necessary to prune at that time of the year if you only have a small number of fruit trees on your property.

They bear fruit on the same lateral spur branches from the main leading stem for many years, so it’s essential to avoid pruning these off because you won’t get any crop.Ī common pest found on apple trees is spider mites. Pruning apple trees is essential to shape them to the desired form for the first couple of years. The best way to stop the spread of this disease is to spray with a copper fungal product before and after the leaves come out. For example, peaches are prone to leaf curl, a fungal disease that makes the leaf curl. Unfortunately, apple and peach trees have the most pests and diseases. We recommend pruning apple and pear trees every winter after the leaf drop before the buds appear to ensure good fruit crops for the following season.
