When to start spraying apple trees?
I'm pretty excited to have just ordered my first apple trees (just moved to a place in the country where I can try out a small orchard!), and I'm pretty confident I know what to do regarding planting and pruning, but I'm not sure about spraying. I've heard that it's more or less impossible to get apples without spraying down here, so I'm all geared up to do that (planning on using the chart on the Johnson's Nursery website to start off), but I'm not sure when to start. Do I start right away when they're teeny baby trees, or should I hold off until they're a couple years old and ready to start producing?
