asparagus fern seeds

instructions

  1. Soak. Soak seeds in warm water for 24 hours.
  2. Sow. Plant 1–2 seeds per soil pod, ¼" deep.
  3. Dome on. Cover with a humidity dome at 70–80°F. A seedling heat mat speeds things up.
  4. Keep moist. Don't let the mix dry out while you wait.
  5. Uncover slowly. After sprouting, open the dome a little more each day.

things to know

  • Foxtail fern: upright, fluffy plumes.
  • Lace fern: flat, lacy fronds, a florist favorite.
  • Basket asparagus: arching stems, great for hanging baskets.
  • Bridal creeper: a climbing vine with glossy leaves. Keep it as a houseplant; it's invasive outdoors in some regions.
  • 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.

plant care tips

  • Light: bright indirect light or a grow light.
  • Water: keep evenly moist. Thick roots store water, so it forgives a missed watering.
  • Humidity: likes it humid. Yellow needles mean dry air or too little water.
  • Feeding: monthly in spring and summer.
  • Repotting: roots fill pots fast, so size up yearly.

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.
