December Care for Christmas Houseplants: Poinsettia, Amaryllis, and Cyclamen
Festive houseplants like poinsettia, amaryllis, and cyclamen are the stars of holiday decor during December. With their bright colors, elegant blooms, and seasonal symbolism, these plants deserve a little extra attention to look their best. Here’s how to care for your Christmas houseplants throughout December so they thrive all season long.
Poinsettia (Euphorbia pulcherrima)
Light:
- Place in bright, indirect light—avoid harsh midday sun.
Temperature:
- Keep between 15–21°C (59–70°F).
- Never let the plant touch icy windows or get a cold draught.
Watering:
- Water when the top of the compost feels dry.
- Ensure the pot drains fully; never leave the plant sitting in water.
Humidity:
- Poinsettias dislike dry air—mist foliage lightly or place a water tray nearby.
Other Tips:
- Remove decorative foils or punch drainage holes for healthy roots.
- Avoid moving the plant between hot and cold rooms.
Amaryllis (Hippeastrum)
Planting (if not bought in bloom):
- Pot up bulbs using peat-free compost, leaving the top third above the soil line.
Light:
- A bright, warm room is ideal during growth; follow the bud as it seeks light.
Watering:
- Water sparingly at first, then increase as the flower spike appears.
- Reduce watering after flowering.
Support:
- Tall stems may need a stake to prevent toppling.
Temperature:
- 18–20°C (64–68°F) for best results; avoid intense heat.

- Keep watering and feeding as foliage develops after blooms fade; move outside after frost for summer growth; dry off and rest the bulb in late summer, then pot again in autumn.
Cyclamen (Cyclamen persicum)
Light:
- Bright but cool location, out of intense direct sun.
Temperature:
- 10–18°C (50–64°F).
- Too much heat leads to yellow leaves and short bloom time.
Watering:
- Water when top soil feels dry, but avoid splashing the crown.
- Water from below (sink pot in water briefly) or around the edge of the pot.
Humidity:
- Enjoys a moist atmosphere with good airflow (but no drafts).
Other Tips:
- Remove yellow or faded leaves and deadhead spent flowers to prevent rot.
- Don’t let the plant sit in water—always allow to drain thoroughly.
General Christmas Houseplant Tips for December
- Avoid over-fertilizing during flowering—feed amaryllis lightly, but not the others while in bloom.
- Wipe leaves gently to keep them dust-free.
- Place away from ripening fruit (ethylene gas causes drop of poinsettia leaves and cyclamen flowers).
- Don’t place plants above radiators or fires—dry air kills quickly.
Cared for properly, your Christmas houseplants will stay beautiful well into the new year—filling your home with festive color, warmth, and healthy green cheer.
