instructions

  1. Pointy side up. Most bulbs have a pointed top; plant that side up. Caladium tubers go knobby side up.
  2. Depth. Caladium and oxalis 1–2" deep; paperwhites with the top third showing (or on pebbles in water); daffodils with tips just covered.
  3. Water once, then wait. Water well after planting, then keep barely moist until shoots appear.
  4. Warmth or chill. Caladium and oxalis: 70–85°F. Daffodils: 12–15 weeks at 35–45°F first. Paperwhites: no chill.
  5. Light. Move to bright light once shoots appear.

things to know

  • Caladium: huge, painted leaves; loves heat and humidity.
  • Oxalis: shamrock leaves that fold at night; easy windowsill plant.
  • Paperwhite: the easiest holiday bloom: fragrant flowers 4–6 weeks after planting.
  • Mini daffodil: needs a cold period before it will bloom indoors.

plant care tips

  • Water: keep lightly moist while growing; reduce as leaves fade.
  • Dormancy: caladium and oxalis rest after their season. Let leaves die back, keep dry, and regrow later.
  • Floppy paperwhites? A splash of alcohol in their water (1 part 40% spirits to 7 parts water) keeps them shorter.
  • Feeding: light feeding while leaves are growing.

faqs

How long do paperwhites take to bloom?

Usually 4–6 weeks after planting.

Do daffodils need to be chilled?

Yes, 12–15 weeks of cold before forcing indoors.

It's going dormant. Rest it dry for a few weeks, then water again.

Are bulbs pet-safe?

No. Caladium, paperwhite, daffodil and oxalis are all toxic to pets.

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.
