I don't know if many of you have fruiting trees or other plants that seem to always have an insect issue, but this book tells me exactly what I need to know to get rid of the problem. And guess what? The advice really works. They haven't left anything out in this book and I got it at a real bargain on O-stock. This book retails for over ***, upwards of *** on some websites, so I feel blessed it's now part of our horticulture arsenal. It'll come in real handy when I take my botany classes I think.
