Rather than going to a nursery or supermarket to purchase pots, the gardener using newspaper pots has all the essential material for the pots on hand. By wrapping strips of newspaper around an old soda pop can and then gently removing the can, a gardener suddenly has a full collection of pots on hand to start seedlings for the growing season.
Not only is the newspaper flower pot a bonus for the gardener, it has real advantages for the sustained growth of the plant itself. When seedlings have to be moved from ceramic or other permanent pot structures so they can be planted in the ground, there is a serious risk of root damage. Delicate hairs that help the plant absorb water from the soil can be injured, and growth can be set back as much as three weeks because of the transplant process.
While almost every other kind of pot costs money, the creation of flower pots from old newspapers is generally free. Even if there is not a stock of old newspapers in your house, it doesn't take long to acquire donations from neighbors and friends who would prefer to see their used newspaper recycled to a new and useful life.
Neither the newspaper itself nor the ink actually add nutritional content to the soil when they are put into the ground as the seedlings are planted. The ink contains carbon, which is good for the plants, and the paper is beneficial in maintaining the moisture content of the soil.
