Toilet Paper Roll Plant Starter

Save the cardboard tube in the center of your toilet paper for starting seeds for your garden.
Bend one of the ends in, to make a base. (If you want to get super neat about it, set the tube up and use a brush handle to push the ends from the other side as well.) Fill with soil, put your seeds in, water. When it is time to transplant these, open the bottom and place directly into the ground, no need to remove the cardboard, it will decompose.

If the plant you are growing is attractive to slugs, use paper towel tubes instead. Cut these in half (for a longer tube) follow the directions, but instead of filling the tube, leave a space on top. This will create a dry collar that the slugs will not want to climb.

You have to start saving these tubes early, if you want to use them for your garden, because you will need one per seedling.
