Overview

Cactus enthusiasts inevitably find themselves wanting to increase their own collection. One way to do this is by planting cactus seeds from your own plant. Although cacti grown this way take longer to mature than those grown from cuttings, some gardeners consider seeds easier to establish. However, if you harvest seeds from your cacti's pods, these seeds will need to be prepared before they can be planted in early spring.

Step 1

Pinch a ripe pod from your cactus.

Step 2

Cut the pod open with a sharp knife.

Step 3

Squeeze the seeds out over a paper towel. Then spread them out and leave them to dry at room temperature.

Step 4

Fill your pot just below the top with cactus potting soil. Pat the soil down with your hand to firm it.

Step 5

Spread the seeds over the top of the soil.

Step 6

Sprinkle a thin layer of sand over the seeds. They should only be partially covered so that some light can still reach them.

Step 7

Water the soil from the bottom up. Place the pot in a shallow pan of water mixed with one capful of hydrogen peroxide (to discourage mold growth). Allow the soil to absorb the water until the top of the cactus potting soil is moist.

Step 8

Cover the pot with a clear plastic bag. Then place it in a spot where it will receive consistent but indirect sunlight. Then wait for the seeds to germinate. (this may take as little as one week or longer than a month, depending on the variety of cactus). Once the seeds sprout, remove the plastic bag. Then sprinkle a little more sand over the seedlings to support them as they grow.
