Instead of buying an upside down tomato planter, you can make one for yourself that will cost nothing except what you spend on the soil and the plant. You could easily make your own topsy-turvy tomato planter in 30 minutes. Once the planter is complete, you can hang the planter anywhere you have plenty of sun to keep the tomato plant healthy so it produces fruit. Planting the tomato in an upside down planter will give you a longer growing season as well.
Make a hole 1 inch in diameter. The bag can be a grocery bag with handles or a gallon size garbage bag with handles.
Place the bag on a table with the bottom of the bag smoothed out. Place the bag on a surface where the bottom is open so that you place the plant through the hole. Two planks over the chair arms will work well.
Gently place the tomato plant through the hole from the inside. On the outside of the bag on the bottom, wrap a piece of paper towel around the base of the plant to prevent the soil you will be adding from pouring out.
Add soil to the bag. Fill the bag up 3/4 of the way up. Pack down the dirt slightly, but not tight.
Pick the planter up and hang on a hook somewhere in the sun.
Poke a hole in the top of the bag for watering. Make sure that you aren't to close to the handles or the bag could rip. Add water to the plant. Use a watering can with a thin spout to make sure that the water gets into the bag. Note: If the handles are far enough apart, you can water through the handles instead of making a hole.
