These lightweight concrete planters are ideal for succulents or alpine plants, which have adapted to growing on rocky ledges and shallow soil. While the process to create these can take some time, the final product is definitely worth it. Be sure to wear a mask and gloves when making these vessels.

How to do it

Part 1

Step 1

Make the cement mixture in a bin using one gallon peat, one gallon "Portland" cement, and one gallon perlite. Wear a mask to avoid breathing dust and use gloves when mixing, as concrete can burn the hands.

Step 2

Slowly add approximately 2 1/2 quarts of water as if you were making dough, being sure to add the last part of water slowly. Humidity can affect how much water you need. The mixture should clump in your fist and hold its shape.

Step 3

Transfer the mixture to a smaller bin. Use any container to shape. If you use metal, oil the interior to prevent binding. Next, shape the mixture into the bin. To avoid suction, use a flexible container. Pack it very tightly to the bottom and sides.

Step 4

Place a lid on the bin to prevent the mixture from drying unevenly, which affects curing. Then, place it in plastic bag.

Step 5

Leave the mixture in the bin for two to three days to dry.

Step 6

Remove the planter from the bin by turning it upside down, being careful not to drop it. Dust loose concrete from the top edges.

Step 7

Let this air dry for another week.

Step 8

To create optional drainage, we recommend drilling holes in the bottom.

Step 9

Finally, fill the planter with shallow-rooting arrangement.

    Difficulty: Kind of Easy
    The video doesn't show the process of actually making the planter, just how to plant it. A walk-thru process of the actual making of the planter would be great!
