Many garden centers and other stores now offer upside-down tomato planters. The planters are hung outdoors from the roof or a patio cover, taking up very little room. The tomato plant then grows upside down, requiring no staking or support to grow straight while supporting its fruit. While different brands may have slightly differing instructions, most of the planters are planted and cared for in the same way. They are a good choice for you if you do not have a traditional garden bed available to grow your tomatoes in.
Place a well-draining, quality potting mix into a 5-gallon bucket. Mix in a slow-release tomato fertilizer following package instructions for application amounts.
Wet the potting mix thoroughly. Mix it together and break up any large lumps in it with your hands. Make sure all of the potting mix is evenly moist.
Hang the planter from a heavy-duty hook that is screwed into a wooden support or rafter. Ensure the hook and bag are in a location that receives at least eight hours of sunlight a day.
Remove the foam or plastic rings inside the planter, if applicable. Pass the roots of the tomato plant through the hole in the bottom of the planter and pull the plant through until the bottom leaves of the plant are snug against the bottom of the planter.
Place the foam circle that has a split in one side around the stem on the inside of the planter, pushing it snugly against the bottom of the planter.
Fill the planter 1/3 full with the moistened potting mix. Set one of the larger foam rings on top the soil, if applicable with your planter, then fill the planter 2/3 full with the potting mix. Place the last foam ring on top of the soil, then finish filling the planter with potting mix.
Water the planter from the top every one to two days. Fertilize with a soluble fertilizer once a month.
