Mammillaria spinosissima 

Sow Mammillaria spinosissima seeds in a cactus mix or well-draining soil. Plant the seeds on the surface of the soil and lightly press them in. Keep the soil consistently moist but not waterlogged. Maintain a temperature of around 70-80°F (21-27°C) and provide bright, indirect light. Germination typically takes several weeks to a few months.

Some of plants may have very have specific germination requirements that may not be covered in these general instructions. 

Many seeds require pre-treatment before sowing which we try to list here when we can, but this information may not be present here.  Germination times and germination temperatures are to be a guide only.  Many factors can DRASTICALLY affect this.


It's always a good idea to research the specific germination requirements from multiple sources for each plant before attempting to grow them from seed.
