Step 1

Find a sterile seed starting mix and cut it with 25% limestone sand to increase drainage. Fill your container two-thirds full with your mix and water in thoroughly.

 

Step 2

Use a flat tool to tamp down the surface so that it is smooth.

 

Step 3

Sow cactus seed evenly on the surface. Do not cover the seed (unless planting Opuntia spp). Sow during late spring and early summer for best results.

 

Step 4

Place tray in partial shade and protect from afternoon sun. Use a misting nozzle to water in the cactus seeds after they are sown.

 

Step 5

Keep soil moist by hand misting or with a misting system. After germination begins, feed once a week with fertilizer. Keep seedlings moist until winter.

 

Step 6

Keep mostly dry during winter. Do not fertilize during cold weather. In the spring, you can transplant your cactus seedlings into individual pots.
