A stack of flower pots creates a focal point in your garden. This vertical structure can be filled with exotic tropical flowers, cascading creeping vines, strawberries, herbs or a variety of different plants. When choosing plants, look for their light and water needs and pair them up accordingly. Use clay or plastic pots in all the same size, or start with a large pot, stacking increasingly smaller pots as you go up. Whatever way you decide to make your stacking flower pot stand, the end result looks impossibly tilted.
Clear an area outdoors for your stacked flowerpot stand. Check to be sure it will be on level ground and then remove any weeds from the area.
Hammer a long piece of reinforcing bar (rebar) into the ground. Measure the length you will need by calculating the height of all your pots. Add an extra 60 cm (2 feet) to your calculations to account for the part that will be keeping the stacked pots stable in the soil.
Slip the largest pot on the rebar so that it sits flat on the ground with the stake through the drainage hole. Pour landscape rock into the pot. Fill it halfway up to provide a heavy base and allow water to drain.
Thread the next pot through its drainage hole into the rebar. Tilt it to one side and then fill 3/4 of the way with potting soil. Do not fill to the top since the pot will be tipped and the soil can spill out when watering. Part of the base of this pot will be resting on the soil of the first pot at a 45-degree angle.
Continue adding pots, tilting each one in different directions and angles. Fill with soil as you go.
Plant flowers as you fill the pots with soil, or wait until the structure is complete. Leave a section of the soil unplanted in all the lower pots so that the next flower pot can rest on it.
Plastic pots can also be used. They are lighter than clay pots. Stacked flower pots can also be made to hang off a shepherd's hook. Instead of sticking the rebar into the ground; bend a loop at the bottom to hold it on the bottom pot. Once the top pot is put on, bend a loop at the top and hang from a strong tree branch or shepherd's hook.
Take the stacked pots apart if you live in an area with harsh winters. Lift each pot off the rebar and store in a warmer area.
