The successful grower I met in Washington irrigates Bud 9 every 5 days. This is under-tree sprinkler irrigation. I do the same and water 1 - 1.5" with each irrigation every five days on average in the summer. If the weather is really hot, say 95F everyday, then I might shorten that to every 4 days. My soil is a silt/loam that has good drainage, high organic matter and holds moisture well. In fact, I was amazed at how much water HC/B9 needs. I believe if you are not irrigating Honeycrisp on Bud 9, you are in trouble. Bud 9 seems to like "wet feet," but at the same time the soil needs air. My philosophy is to water an inch plus, and then let that drain down and give the trees a chance to have air for a couple of days, and then do it again. I can see stunting if the trees get dry, as the roots will send a chemical signal to the upper part of the tree and tell it to "stop growing." My sense is that Bud 9 has a hair trigger on sending that signal. I just assumed that all orchards back East have irrigation, if not, then I would bet a cheeseburger that this is the problem with runted out Bud 9's.
If I had a stunted Bud 9 block, I would get a soil test and a tissue test and POUR the nutrients on the block and NEVER let the trees dry out too far. I would crank up the NPK and minors at the expense of fruit quality for a season and then back off the N for fruiting if the trees recover. My two cents...
