I am beyond ready for spring. Last weekend I started getting my flower beds ready, and soon I want to buy some pansies and perhaps some perennials. I hope that this year David won’t pick all my flowers off.
Here’s a book I’ve found helpful: 
The Perennial Care Manual – A Plant-by-Plant Guide: What to Do & When to Do It by Nancy J. Ondra
I love how the book is organized – there is a plant reference section that contains tips for each season. For example, there is an iris section that explains what to do in the spring, summer, and fall/winter – just for irises. She includes information for 125 perennials, plus other information such as pest control and propagation. I love perennials and I seem to collect them from many people, but I don’t always know what to do with them. (And the photos are helpful for when I get a plant from someone and they don’t know the name of it!)
Happy Spring!
