Supplies you will need:

  • Various containers- You can use almost anything, plastic and cardboard containers are recommended because they separate easily from the cement. In order to make your mold you will need to nest two containers together. Both should have sides that are straight or taper out and make sure that there is a gap of at least 3/4 between them.
  • Peat Moss- fine textured, crushed
  • Perlite- fine textured, crushed
  • Portland Cement- Make sure that you use real Portland cement and not a quick-set material
  • 1 quart measuring cup
  • Wheelbarrow or Rubbermaid bin for mixing
  • Gloves
  • Dust Mask
  • Mold Release Spray –non-stick cooking spray could work too
  • Sand
  • Plastic bags/sheeting
  • Rubber mallet
  • {For a birdbath or tabletop -concrete/masonry waterproof sealant}

1. Mix together equal parts perlite, peat moss and Portland cement in a large container. The amount you use of each does not matter as long as they are equal parts. I used 2 quarts of each. Make sure you wear gloves!

2. Slowly begin to add water and mix until mixture is the consistency of cottage cheese.

3. Coat containers with mold release spray.

4. Pour mixture into the outer mold until it is an inch thick. Add the inner container and start adding mixture around all the sides.

5. Fill the inner mold with sand or water to steady it. Pack mixture in tightly.

Cover the containers with plastic.

6. After 24 hours remove the inner mold. Use a rubber mallet if needed to knock the container loose from the mold. Replace plastic.

7. After 36 hours remove outer mold.

8. After removing molds, you can drill holes using a masonry bit in the bottom of the container for drainage. Use a planer file or sand paper to smooth out any rough edges.

9. Re-cover containers with plastic and let sit for several weeks in order to finish curing.

Finally, your pots will be finished!
