What differs for your space?
Dahlia is listed for full sun (6+ hours), while Poinsettia (Christmas Star) is listed for bright indirect light. Record how many hours of direct sun your intended spot receives and confirm the match locally.
Dahlia has a recorded range of 5–30°C; Poinsettia (Christmas Star) is listed at 10–30°C. The recorded ranges overlap from 10 to 30°C. That overlap compares the draft entries; it is not proof that either plant will suit the spot.
Both are marked moderate in the catalog. This shared estimate does not mean identical care.
Make the next care decision at the pot.
A comparison cannot set a watering date. Check moisture first: pot size, growing mix and current weather change how quickly a container dries. Record what you notice and decide when to check again.
Read the RHS guide to watering containers for general container advice, or use Plont’s plant observation checklist. The RHS source supports this general advice; it does not verify the species-specific draft values above.
