To make your own biodegradable mini-planter (that's right, no transplanting!) How to make it: 1. Using scissors, cut six to eight small slits in the end of your toilet paper roll (if using a paper towel roll, cut the roll into three pieces before beginning this step). 2. Fold the strips down so they overlap. 3. Fill carefully with wet soil, and set in a baking sheet. 4. Plant one seed per roll. After germination, just plant the whole thing in your garden!
