yucca seeds

instructions

  1. Soak. Soak seeds for 24 hours.
  2. Sow. Plant 1–2 seeds per soil pod or deep pot, ¼" deep, in gritty mix.
  3. Warm and bright. Keep at 70–85°F under a humidity dome; a seedling heat mat helps.
  4. Remove the dome early. Take it off once seedlings appear; yuccas hate damp air.
  5. Deep pots. Move seedlings to deep pots; yuccas grow a long taproot.

things to know

  • Blue stem yucca (Yucca baccata): blue-green leaves, very cold- and drought-hardy.
  • Beaked yucca (Yucca rostrata): a striking blue 'pom-pom' of leaves on a trunk over time.
  • Slow but tough: expect a small plant the first year.
  • Pick a planter that holds moisture: plastic, rice hull or ceramic, with a dome. Skip terra cotta, peat pots, coco coir pots and egg cartons. They wick water away from the seed.

faqs

How long do yucca seeds take to sprout?

Usually 1–4 weeks with warmth.

Can yucca grow indoors?

Too wet. Use gritty soil and water less.

Is yucca pet-safe?

No. It's toxic to cats and dogs.

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.
