How to Place Styrofoam in Glazed Pots


Extra large glazed pots make attractive decorative containers for potted plants. When filled with a variety of flowers, a large container can support a beautiful living bouquet. Before you plant in a large, clay pot, you must you must modify it. If you just dump in the amount of soil required to fill it, you will end up with water-logged soil and plants that are susceptible to root rot. Avoid this problem by filling the excess space in your pot with Styrofoam packing peanuts. Your soil will drain more readily and your pot will be much easier to move.

Step 1

Scrub the interior of your pot with a stiff brush dipped in a bucket of soapy water to which 1/4 cup of bleach has been added. Rinse out the interior thoroughly with a hose, then allow it to air dry or wipe it dry with a clean, lint-free towel.

Step 2

Estimate how deep you will need the soil in your pot to be and how large a plant will fit. In general, the depth of a plant's roots are equal to the height of its foliage. Research the plant's potential height; this is how deep your soil needs to be. For more precise measurements, consult the garden center where you purchased the plant.

Step 3

Fill the container with styrofoam packing peanuts, leaving enough room at the top of the container for the amount of soil your plants will need.

Step 4

Place a few sheets of newspaper over the styrofoam peanuts to keep the soil from falling through.

Step 5

Add soil and plant.
