Cacti can be propagated through several methods, including offsets (pups), seeds, and stem cuttings.
1. Offsets (Pups)
Many cacti, such as the Echinopsis or Mammillaria, produce offsets that can be removed and replanted.
- Steps:
- Gently separate the offset from the mother plant using a clean, sharp knife.
- Allow the offset to dry for a few days to form a callus.
- Plant it in a well-draining cactus mix and water lightly.
2. Seeds
Growing cacti from seeds is a rewarding but slower process.
- Steps:
- Start seeds in a shallow container filled with cactus mix.
- Lightly sprinkle the seeds on top and mist with water to moisten the soil.
- Cover the container with plastic wrap to retain humidity and place it in a warm, bright location.
- Once seedlings emerge, remove the plastic and care for them as you would mature cacti.
3. Stem Cuttings
Some cacti, like Opuntia (prickly pear), can be propagated from stem cuttings.
- Steps:
- Cut a healthy stem segment using a sharp knife.
- Allow the cutting to dry for a few days to form a callus.
- Plant it in well-draining soil and water lightly.
