mesemb seeds

instructions

  1. Use gritty mix. Coconut fiber or cactus mix plus extra sand or perlite(nothing too chunky), watered well.
  2. Surface sow. Sprinkle seeds on top, mixed with a pinch of sand. Don't cover.
  3. Dome on. Cover with a humidity dome at 65–80°F in bright light. Cooler nights help.
  4. Keep consistently moist. Bottom water the planters to avoid pouring water on the seeds and removing the dome.
  5. Air out slowly after they sprout, then start to let the mix dry slightly between waterings as they grow.

  • Light: very bright: a sunny window or a grow light close above.
  • Water: let the soil dry fully between waterings once mature.
  • Rest periods: most rest in summer or winter. Water much less when growth stops.
  • Soil: very gritty and fast-draining.
  • Feeding: rarely. A weak feed once a year at most.

faqs

What are mesembs?

Small South African succulents in the ice plant family, including lithops, baby toes and tiger's jaws.

Why are my seedlings stretching?

Not enough light. Move them closer to a grow light.

How often should I water?

Seedlings: keep lightly damp. Mature plants: only when fully dry.

Are mesembs pet-safe?

They're generally considered non-toxic, but don't let pets chew them.

these are key aspects of your setup

check your setup!

  • 💡light: is your setup away from direct sun? these seeds should stay in indirect or filtered light, or better yet, under grow lights.
  • 💧moisture: does the soil feel very moist to the touch?
  • 🌡️temperature: is the setup away from direct sun, open windows, or heat vents? make sure it stays consistently between 70F-90F (use a heat mat if the temperature falls under 70F)
  • ☁️humidity: do you see condensation on the humidity dome? if not, make sure the dome is fully sealed, the setup is warm enough, and there's enough moisture in the soil.
  • 💚care: leave the dome on and only open it once a week to add water.
