I bought this book a couple of days ago. Utterly fascinating.
You can find it here as a download. I bought the .pdf, printed it, three-hole punched the pages and put it in a binder so I can read in bed at night and skip staring at a screen.
I’ll have to post a full review when I’m done reading. I’m half-way through it now and I believe it’s going to prove greatly helpful in my new quest to grow good apples in Florida.
