|what type of fertilizer would I use on my apple trees.They really took a beating last year. bugs, rust,all the leaves fell off
|While good nutrition is important, it may be that your apple tree needs to be put on a regular spray schedule to help it avoid diseases and insect problems next year. To avoid diseases, your apple trees can be sprayed with Bordeaux (lime-sulfur). This fungicide must be applied early and thoroughly to protect new growth. Apply according to label directions; as the buds break until the leaves are fully expanded. Do this at prepink, pink, calyx, and first cover. Since the fungus overwinters in fallen leaves and fruit, be sure to thoroughly clean up and dispose of plant debris in the fall months. Horticultural oil is effective against overwintering scale insects and insect eggs and should be applied in the winter. It is sold as dormant spray. Hope this answers all your questions.
