How to Put Foam in Containers for Plants


Floral foam works to help individuals and florists design flower arrangements that will stay in place. Stems can easily be pushed into the foam. Floral foam comes in many shapes and sizes to fit almost any plant container. The foam can also easily be carved to fit a container. If you are looking for a quick and easy way to create an arrangement, floral foam is your answer.

Step 1

Mix a floral preservative together with some water. Follow the mixing instructions on the floral preservative packet.

Step 2

Soak your floral foam in your water/preservative mixture. Let it sit for half an hour.

Step 3

Carve your piece of foam to fit the container you plan to use if you didn't buy a piece of foam that was an exact fit. This can be done with a sharp knife. Just carve off edges until it fits tightly in the container.

Step 4

Set the floral foam in the bottom of the container.

Step 5

Choose your flowers and stick them in the floral foam one at a time. Push the stems in at an angle so that they stay in place.

Tips and Warnings

  • Only add candles to your flower arrangement if you purchased fire-retardant floral foam.
