Do any of you have good suggestions for a book(s) on pruning and trimming? I found one thread with some info: http://www.lawnsite.com/showthread.php?t=88765 Post #4, picture of a bookshelf I don't do very much trimming and pruning work (primary work is mowing), but have a customer wanting me to do things I don't think are appropriate. This customer has potential for much work (already did much work in the Spring - 26 hours worth, and more work recently). I want to have some authoritative source that I can use to help make my recommendations (or rejection of her decisions) on what should be cut when. The most important issue now is timing. I think I can do pretty well on technique (probably have fooled myself here too!), but the the timing issue is important. She wants some things cut NOW, and I don't think NOW is the right time, or best time. After 12 years of moving into a new home (very large, much landscaping work), she claimed never to have found a contractor who will do a "complete" job for her. Some come, work a day, leave and never return -- too big of job, too difficult. If I can do a good job for her (she was very pleased in early spring), I can have much work. But, I want to do the work right. Any suggestions beyond the comments in the thread I already found. I am in SW PA, so a book devoted to desert plants does me no good, nor one devoted to tropical plants is no good either.
