Begin with quality seeds from a reputable dealer. Fresh seeds bought will germinate better, so determine the source carefully. Soften the outer skin of the seeds by soaking them in hot water for two hours before sowing. This will cause them to germinate quickly.

Use a good draining soil mixture for the germination of the seeds to be successful. Combine sand, perlite, and cactus potting soil to create a loose and light soil medium. Sterilize the soil by baking it in an oven at 180°F (82°C) for 30 minutes to kill the deadly fungi and bacteria.

Place the prepared mixture of soil in a shallow pan. Press seeds gently on the surface but don’t cover them as they require light to develop. Water the soil with mist water uniformly. Seal the container using a clear plastic cover or plastic wrap to ensure humidity.

Put the container in a light, warm location with filtered light. The temperature for germination should be 70-80°F (21-27°C). A heat mat can provide consistency of heat. Water the soil lightly but not too much, as water will cause rot. Mammillaria spinosissima can be good friends

Germination will take place within two to four weeks. Once the seedlings emerge, gently take off the plastic cover so they can get used to normal humidity. Give them light but filtered sunlight to avoid sunburning. Continue to keep the soil lightly moist.

When, after several months, there are very few spines on them and half an inch (1 cm) high, transplant them individually into small pots. The same soil mix originally, and the least amount of root manipulation, is used here. Take sips slowly on them in an attempt to provide the roots with strength that will maintain them well-developed.

After the cacti have grown, put them in bright indirect light and water the soil sparingly when dry. Water hardly at all during winter since Gymnocalycium capillaense is dormant. Provide light feed in spring and summer with weak cactus plant feed to promote growth.

It takes a while to grow Gymnocalycium capillaense from seeds, but it is easy if you give them the right conditions. Just do these steps, and you will easily be able to grow these lovely cacti and enjoy their special beauty for years to come also.
