1) Helps them drain, and
2) Reduces contact between a flower pot and, if on a deck, the wood, which in turn reduces the chance of rot.
We are offering a group of three pot risers or pot lifts. If you wish to purchase one more for an extra large pot or for a square or rectangle pot, just convo me and I will add another listing with four risers.
Our own designed shell pot risers are made out of concrete, the concrete is our special blend of materials that produce an extra strong concrete that is frost resistant.
The shells are around 3 1/2'' high, the part that the pot sits on is 2'' x 1 3/4'' and 3/4'' thick.
