Cardboard Seed Tubes
For an easy and green way to start seeds, save your toilet paper and paper towel tubes. Cut the tubes into 2 in. lengths and set them in a waterproof tray. Fill the tubes with potting soil and plant your seeds. When the seedlings are ready to move to the garden, plant them right in their cardboard tube. The cardboard will decompose. Be sure to keep the tube below the soil surface, so it doesn’t wick moisture away from the roots.
