You should reread that post. Fruitgrower said it stopped raining in early April and turned hot and windy. His June Pride came off in late June as I recall. That’s 2.5 months with little rain or irrigation and lots of 100+F weather. If you had 2.5 months like that in NY I think you’d call it dry, forest fire dry. Which by the way is exactly what happened near him in CA starting in June.
But then again this question is about fertilizer not water. I just keep my trees green and thin for size. Works for me.
