Upside-down tomato planters have become a staple in garden centers. They are sold as a space-saving garden device for apartment dwellers or those who are otherwise limited in space. The planters are hung in a sunny area, and the tomato plant grows from a hole in the bottom. Like most containers, an upside-down planter may not grow a plant that produces as many fruits as a garden-grown tomato, but the method is a viable alternative if a traditional bed isn't available. Instead of purchasing an expensive planter system, make your own.
Draw a 2-inch square in the center of the bottom of a 5-gallon bucket. Cut the square out with a sharp utility knife, cutting away from yourself to avoid injury.
Cut a circle from landscaping fabric that is 3 to 4 inches larger in diameter than the bottom of the bucket. Line the inside of the bucket with the fabric and cut an X in the fabric over the square hole you cut out.
Prop a broomstick up on two tables, and hang the bucket handle over the broomstick. This elevates the bucket off the ground as you work.
Slide the roots of the tomato seedling through the hole in the bucket and landscaping fabric, from the outside in. Hold the roots in one hand as you scoop soil into the bucket with the other hand. Firm the soil lightly around the plant's roots to hold it in place.
Fill the bucket half full with soil, then water the soil until the excess moisture begins dripping out around the plant's stem. This collapses any air pockets in the soil. Finish filling the bucket with soil, then water a second time.
Place the lid on the bucket to help retain soil moisture. Hang the bucket by the handle in an area that receives at least six to eight hours of sun a day.
