Using the space that traditional hanging planters would take up, upside down hanging plants can produce as much food as a regular container-based plant. Instead of cherry tomatoes or flowers, the upper space in a container garden can grow full-sized tomatoes, cucumbers or peppers.
Place the seedling in the bottom of the hanging planter, with the leaves and stem on the outside and the root ball snug against the bottom of the planter inside. Hang the planter up to free up your hands, or have a friend hold it. The plant will be outside the planter, hanging upside down out of the bottom of the planter.
Add potting soil to the planter until you see that the root ball has been covered. Pat down the soil to make sure that there is firm contact with the entire root ball, and that there are no air pockets next to it.
Fill the rest of the planter with potting soil until you reach about 1 inch from the top. Water with soluble fertilizer and hang in a sunny place.
Water your plant whenever it seems to be drying out. In summer months, you may have to water every day, as these planters seem to dry out faster than traditional planters.
Watch your plants when they are first growing. When first planted, stems may try to bend around and go back into the hole and grow up through the dirt. If this happens, gently pull the stem back out into the air. After the plant has a good amount of leaves and some weight, this will no longer happen. The plant will adapt to growing upside down, and will continue to grow straight toward the ground.
