How to Make an Upside Down Planter

Since your planter will hang upside down, you’ll plant your herb through the bottom of the pot instead of the top. To fit it through, cut a 2-1/2-inch hole in the bottom of the pot using your hole saw. Use protective eyewear while cutting plastic.

Using the bottom of the pot as a guide, use a utility knife to cut a circle from the air conditioner filter of the same size. Fold the foam piece into a cone and, using scissors, cut the tip of the cone to make a hole in the center of the circle. Then, cut a radius in the filter circle. Your piece should look like a donut with a line going through one side.

Drill two 1/4-inch hanging holes on opposite sides of the pot. Place them 3/4 inch down from the top edge of the pot. You may want to drill over a piece of scrap wood to steady the pot while you work.

Thread one end of the rope through a hole from exterior to interior and tie a knot inside the pot to secure it. Repeat with the other side. You can use one continuous piece of rope or two single pieces depending on how you want to hang the pot. Hang the pot where you can easily access it to work on planting. (This doesn’t have to be its permanent location.)

Remove your plant from its nursery pot and carefully brush away enough soil from around its roots so that it fits through your container. Insert the root end of the plant in the hole you cut in the bottom of the planter. From the top opening of the pot, put the foam filter around the stems of the plant and press it into the bottom of the pot to prevent soil from spilling out. Add additional soil and hang in the desired location. Water your plant from the top end of the pot.
