Water an indoor poinsettia when the top inch of soil feels dry, which is usually about once a week, but it can range from every few days to every 1–2 weeks depending on room temperature, light, and pot size.

Quick Scoop

  • Check the soil with your finger every day or two; water only when the top 2–3 cm (about 1 inch) feels dry.
  • In many homes this works out to roughly once a week, but in warm, bright rooms you might water 1–3 times per week, while in cooler rooms it can stretch closer to every 10–14 days.
  • Always water thoroughly until a bit comes out of the drainage holes, then empty the saucer so the roots never sit in standing water.

Simple watering routine

  1. Gently press a finger into the potting mix up to your first knuckle.
  2. If it feels dry, give the plant a slow, thorough drink with room‑temperature water until excess drains out the bottom.
  1. Wait about 10–15 minutes, then discard any water left in the cover pot or saucer so you avoid root rot.
  1. Skip watering if the soil still feels moist; poinsettias handle slight dryness better than being constantly soggy.

Seasonal and indoor tweaks

  • In warm, heated winter rooms, soil dries faster, so you may need to water more often than “once a week.”
  • During the plant’s rest period after flowering, it needs less water—usually a light watering about once a week just to keep the soil from fully drying out.
  • Smaller pots dry out faster than large ones, so mini poinsettias often need more frequent but smaller drinks.

Signs you’re over‑ or under‑watering

  • Drooping, yellowing lower leaves and constantly wet soil usually mean overwatering and possible root rot.
  • Wilting, crisp leaves and soil pulling away from the pot edges signal underwatering; a deep soak should help it recover if caught early.
