polka dot plant seeds

instructions

  1. Moisten the mix. Fill a soil pod or small pot with moist, light seed mix.
  2. Sow shallow. Scatter 2–3 seeds per cell and barely cover them, about ⅛". They need some light to sprout.
  3. Dome on. Cover with a humidity dome and keep at 70–80°F. A seedling heat mat helps in cool rooms.
  4. Bright, not direct. Place in bright indirect light. Mist when the surface looks dry.
  5. Thin and harden off. Once seedlings have 2 true leaves, keep the strongest one per cell and open the dome a little more each day.

things to know

  • Fast and forgiving: one of the easiest houseplants to grow from seed.
  • Color comes with light: the pink, red or white speckles get stronger in bright light and fade in low light.
  • Soil: light, well-draining coir or peat-based seed mix.
  • 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 12–14 hrs/day.
  • Water: keep evenly moist. It droops dramatically when dry but bounces back fast.
  • Pinch: pinch the tips every few weeks for a bushy plant, and remove flower spikes to keep it leafy.
  • Feeding: diluted liquid fertilizer every 2–4 weeks in spring and summer.
  • Pests: watch for aphids, whiteflies and fungus gnats.

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.
