I've moved back onto my family's farm, and there is an old orchard - about 20 trees, mostly apple. The trees are spaced about 20 feet apart, and grass grows right up to their trunks. What is the best thing to do for them, when I don't have time or energy to really take on the orchard yet? Can I mix clover seed in with the grass? I've mulched around a few of the younger trees with shredded wood and soybean stalks, but my hens tear it right up. The trees are bearing pretty well, but especially after two years of drought, I'd like to help them. Any ideas that are fairly low input, to last a few years until I get other parts of the farm in order?
