I use toilet paper rolls to make seed starter pots.
* Cut each roll in half
Fill the “pot” with potting soil, plant your seeds and water gently. Put the seed pots on an old cookie sheet (should hold about 18 pots) and placeunder grow lights or ina sunny window until they are ready to go outdoors. When you are ready to plant, you can either pull the cardboard away from the soil and put the plant in the ground, or simply plant the whole pot — the cardboard will slowly disintegrate.
