  • 1 1/2 parts Sphagnum peat moss
  • 1 part Portland Cement
  • Optional: 1 part water mixed with cement tint

Step 1:  Spray inside of plastic pumpkins

Plastic trick or treat buckets will be the mold for your hypertufa pumpkins. Using your no-stick cooking spray, completely cover the inside of all containers and the outside of all plastic cups or small plastic containers you will use to add indents in the pumpkins.

Step 3: create hypertufa 

Now put on your gloves, safety glasses and a mask. In a well-ventilated area, add dry Portland cement to your moss and perlite mixture to create the hypertufa. Blend these dry ingredients by hand.

Next, slowly add water and begin mixing with a concrete trowel to work in all the ingredients. To get the right consistency, squeeze a handful in your hand. It’s just right when very little water seeps out.

Step 4: Fill Hypertufa Pumpkin containers and cover

Take handfuls of the hypertufa mixture and fill the plastic pumpkin containers to the top. Pack down as you go. When full, push in plastic cups or small plastic containers as inserts. Continue filling all other pumpkin containers with the mixture in the same manner. 

Now place all your hypertufa pumpkin containers inside a plastic garbage bag for curing. After a few hours of hardening, remove the plastic inserts.

Step 5: cut away plastic from hypertufa pumpkins

After two days, remove the hypertufa pumpkins from the plastic garbage bag. Use hand pruners to cut away the plastic pumpkins. Cut along the indentations on both sides of the pumpkin. Peel away the plastic until the hypertufa pumpkin slips out.

At this point, it’s important to soak the hypertufa pumpkins with water once a week to remove residual lime from the cement because it could harm plants. 

 

Plant succulents in your hypertufa pumpkins for a decorative look ll The Home Depot Garden Club

Step 6: plant succulents in hypertufa pumpkins

When your pumpkins completely dry, add decorative touches.

For the hypertufa pumpkins with planter tops, plant succulents and surround with decorative moss. They look pretty in a decorative setting with your hypertufa pumpkins with stem tops.

Be sure to surround your decorative hypertufa pumpkins with plants of the season. In addition to succulents, add garden mums, brightly-colored coleus, plus pumpkins and gourds, available at your local The Home Depot Garden Center. For added ambiance in your fall decor, don’t forget lanterns with LED candles

No matter where you place your hypertufa pumpkins, whether on your porch, balcony, by your entryway or fireplace, these decorative pumpkins for Halloween can be reused year after year.
