This is a fantastic little booklet. It covers everything you need to know to grow dahlias. Dahlias have some specific needs that are different from other flowers, tubers or bulbs. This book covers it all from soil type, fertilizer, pest control, staking, starting in pots, cut flowers, winterizing, etc. I've purchased multiple copies and give them away to friends with tubers I have divided. If you follow the info in this book, you'll have no problem growing beautiful dahlias!
