If you don't own a greenhouse, you might think I'm crazy for saying this already, but winter is a great time to plan your garden. Plus, this simple activity reminds us that spring is coming and one day winter will be gone (maybe that doesn't excite you, but it sure does me!).
So grab yourself a pencil and some paper and get busy.
Decide what areas of your home you're going to spend time on. Petunias in hanging baskets? A shrub by the front door? Something around the mailbox? Don't forget these little areas.
I'm a visual person and like to sketch the outlines of my garden and draw miniature plants with labels on my paper. If I were a really good artist, I wouldn't need labels, but I'll be satisfied with my artistic abilities for now. It's just a garden sketch, and I don't need to impress anyone.
Then make two lists, one for the things you can pick up now (potting soil, garden tags, seeds, mulch, garden tools) and one for the things you'll have to buy just before you need them (plants). Spend some time picking up things on the first list and save the second list for when the earth starts to wake up.
I promise you, you will be glad you did this when the snow was blowing and you were getting depressed with the dark evenings and short days. It will give you hope for the future and save you some time in the spring.
