Has a nice, folksy, honest feel to it. Lots of pictures is great. People like pics.
As far as just picky little stuff . . .
On the HOME page, phone number only. No need for the word "Contact."
Pruning page, under We Do and We Don't, no need to repeat the We Do's/Don'ts, but at least be consistent with all items. Either repeat, or don't. Under When to Prune, in Fall or in the Winter, "the" on both, or neither. Late Winter or early Spring, no comma. Under Why Prune, put the "I mean" sentence in quotes, like someone else is saying that, not you.
The logo is beautiful! Background colors and pics are excellent. I think I'd sneak in my phone number discreetly somewhere on all pages.
