I read this book and I use it as a reference for my job. I am a horticulture Specialist with Lincoln University Cooperative Extension. I received some great tips like cutting the seedlings of onions and scallions in half after three weeks of growth to help them come back stronger. The pictures and tips are wonderful. The passion that the authors have for gardening definitely show through in this book. This book is great for the beginner as well as the advanced gardener.
