How to Germinate Succulents

Mix 50 percent pumice with 50 percent peat and spread it out on a baking sheet. Place the cookie sheet in the oven at 350 degrees Fahrenheit for 30 minutes to sterilize it. Unsterilized potting mix could contain pathogens harmful to seeds and seedlings.

Fill a plastic pot with the sterilized potting mix and sprinkle the seeds on top of the mix. Cover the seeds lightly with coarse sand. The pot can be any size. You can even re-use yogurt cartons as long as they are clean and you poke drainage holes in the bottom.

Place the plastic pot with seeds into a small plastic tub. Fill the tub with water until half of the pot is submerged. Overhead watering can dislodge tender germinating seeds or even kill them. Submerging the pot in water allows water to seep up through the bottom, providing moisture without damaging the seeds.

Stretch plastic wrap over the tub to help trap moisture and raise the humidity level. Place the entire container outside in a bright location, out of direct sunlight. Check the water level periodically as it may take two or three weeks before the seeds germinate.

Lift one or two sides of the plastic wrap once the seeds have germinated, but don't remove it. This will gradually reduce the humidity level and prepare the seedlings for transplanting.

Remove the plastic wrap after a few days and use a misting nozzle on your garden hose or a spray bottle to keep the seedlings moist. Keep the soil moist but not soaking. Once the seedlings are 1 inch in diameter, they can be transplanted to individual containers.
