Tomato trees make use above-ground space, maximizing the amount of plants that can fit into a small garden. This makes them ideal for urban gardens, container gardens and small planting spaces. If you don't have a garden, tomatoes can still be grown on a patio, balcony or sidewalk. These trees are variations of upside-down tomato planters but feature several planters tethered to a single "trunk" instead of individual hanging planters.
Place a Shepard's hook in a location that receives full sun for at least eight hours per day.
Cut a 3-inch hole in the side of the first coconut fiber liner using a utility knife. Position the hole approximately in the middle, equal distance from the top and bottom of the basket. Create two more holes, equally spaced, so that each basket has three planter holes in the sides of its fiber lining.
Cut the same size hole directly into the middle of the bottom of the fiber lining for each basket, creating three baskets with four holes each.
Hang the first empty basket on the Shepard's hook. Thread a tomato plant, leaves first, into the hole in the bottom of the basket, leaving a dangling plant whose root ball is inside the basket.
Hang the other two baskets. Repeat threading the remaining 11 plants into the remaining 11 holes. It's okay if the plants in the side holes droop a little. Reposition them later when soil is added.
Stand on a step stool, if necessary, and add soil to the hanging baskets. Fill them half-way and readjust the plants' root balls, if necessary. Fill the baskets to the top with soil.
Water the baskets until the soil is completely moist. Add more soil if watering caused the soil to settle. Fertilize with a solution suitable for edible foods every two weeks, following the label instructions for dosage details.
Water once of twice daily in the heat of summer to make sure the soil stays consistently moist.
