Reblooming Poinsettias and Preventing Fungus Gnats

Reblooming Poinsettias and Preventing Fungus Gnats

Old potting soil left in a shed harbors fungus gnat eggs. Repotting into it brought them indoors.

Gnat Prevention

  • Use fresh, well‑draining potting mix.
  • Empty drainage tray 1 hour after watering.
  • Water only when soil surface has been dry 4 days and pot feels light.

Strict Rebloom Schedule

  1. June: Move outside, partial shade, continue care.
  2. Early July: Pinch each stem by 1 inch.
  3. Mid‑August: Pinch new growth, leave 3–4 leaves per shoot. Bring inside to brightest window.
  4. September: Keep above 65°F.
  5. Oct 1 – Nov 30: 12 hours darkness (5 pm–8 am) – use opaque box or closet. Daytime in sun.
  6. Late November: Stop darkness; buds should show.
  7. Dec 15: Stop fertilizing. Water normally. Bloom for Christmas.

Follow this exactly; any light leak during darkness delays blooming.
