My first experiment with apple trees was the spring of 2012. I planted 500 trees, mostly on bud 9. I didn't do a soil test before planting as the USDA rates the soil here as being "prime farm land" with a Ph of 7. I planted and used a NPK slow release (Osmocote). The next year, before my next planting of 1100 trees (mostly bud 9) I did a soil test and found I was low on Boron,copper, Zinc and sulfates. I have since paid very close attention to the nutrient levels (tissue testing) and keep the levels way up. What I have found is that the new planting is nearly as big as the first planting, and it looks like some of the Bud 9 trees from the first year may runt out. My take away from this is that Bud 9 trees need high levels of nutrients to push them along in the early years, and may never recover if they lack plenty of food. I plant 3x12 and see no problem at all with filling the space. Fingers are crossed.
