Hi, I'm John Banks, a retired brewer from Ceritos, California. Relief at last! An Exceptionally fine Book! I like to garden and I spend a great deal of time outdoors. I also have allergies, worst in the spring and summer. I met the fellow who wrote this book at the LA Arboretum one day last year and he sent me a copy of the manuscript before it was actually printed. Wow! This book is full of information you just can't find any place else. I made some major changes in my own yards after reading this. Got rid of a bunch of male plants and replaced them with females. This book is the only one that lets the reader know exactly what to use and what not to use. Already this spring I noticed that I'm not having nearly the allergy I was having last year, and I'm sure the changes I made are what did it. I've never gone to the trouble to review a book before but Allergy-Free Gardening is so useful I felt like I just had to write one. If you have allergies or your family members do, check this book out. Actually, if you have friends who have allerguies ( and nowadays who doesn't?) I'd be sure to tell them about it too. You'll be doing them a real favor. One last thing, Ogren wrote this book so it would be useful anywhere in the world. It covers all the kinds of landscape and garden plants grown in the US, in Canada, Europe, Asia, New Zealand, Australia, the tropics, all over. It's a very thourough, readable book.
