Germination of
Puya alpestris
Sapphire Tower: Blue cactus, Pincushion cactus
Puya alpestris seeds can be sown in a well-draining, sandy or gritty soil mix. The seeds should be soaked in water for 24 hours prior to sowing to improve germination rates. Sow the seeds about 1/4 inch deep in the soil mix, and cover the container with plastic wrap or a clear lid to create a humid environment. The container should be placed in a warm location with bright, indirect light. Keep the soil moist but not wet, and mist the seeds with water as needed to maintain humidity. Germination should occur within 2-3 weeks.
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.
