Good Fruit Grower magazine, good read
This month there are good articles on fire blight, irrigation, and grow regulators to promote branching and reduce excess vigor. Any serious fruit grower should consider a subscription, $75 for three years. About 16 issues per year. Since it's out of WA it centers on that industry. But there are frequent articles about the Eastern and Midwestern US.
I've been a reader since the 70s. No affiliation or any other reason to promote other than all I've learned over the years.
