Poinsettia care
Poinsettia problems, one clear next check.
Start with what changed: falling leaves, a limp plant, dark tissue or fading colour. Compare the pot and recent exposure before deciding on water or treatment. A healthy green poinsettia can also be kept beyond the holiday display.

Before you act
Check the plant part, root ball and timeline
1. Start with the visible change
Choose poinsettia in the diagnostic Finder, compare the symptom pattern and follow the next safe check. Leaf colour alone cannot identify a disease.
Open the poinsettia Finder2. Check the pot before adding water
Compare accessible mix with the weight of the same pot. Remove its cover and look for trapped water and drainage holes. Give bright daylight away from cold glass and direct heating; a limp plant in wet mix needs a different response from one with a genuinely dry root ball.
Check moisture and drainage3. Reconstruct the recent conditions
Record cold transport, a new position, heating and when the damage began. Examine leaf undersides if there are live insects or sticky deposits. Keep the plant out of reach of children and pets, avoid ingestion and protect skin and eyes from sap when handling broken stems.
Follow the leaf-loss checksBrowse problems by symptom

Leaves and urgent changes
Start here when the plant is changing unexpectedly. Leaf fall, wilt and dark tissue each have their own first decision. None of them identifies a specific disease from colour alone.
Why Is My Poinsettia Dropping Leaves?
Check the root ball and recent cold exposure before watering a poinsettia that is dropping leaves. A dry, light pot supports a water-shortage explanation; a wet, heavy pot calls for drainage and root checks. Separate falling green leaves from ageing coloured bracts, and inspect leaf undersides if there is stickiness or visible insect activity.
Open answerWhy Is My Poinsettia Wilting?
Feel the accessible root ball, lift the pot and empty any water trapped in the cover. Water is appropriate when the root ball is dry; it is not the next step when the plant is wilting in wet mix. A soft stem base, deteriorating roots or rapid collapse requires a closer assessment. Also consider recent cold exposure or a broken branch.
Open answerWhy Are My Poinsettia Leaves Turning Black?
Darkened poinsettia leaves or bracts after cold transport may be cold-injured, but colour alone cannot confirm that. Check whether the dark area is damaged tissue or a surface coating, whether the stem base is firm, and whether the root ball stays wet. Stabilise the conditions while you investigate. Tissue that has died will not become green again.
Open answerWatering and another growing season
Use a moisture-based watering routine. Keep a healthy plant after its coloured display; plan pruning and repotting around condition and growth. A new coloured display is optional and needs bright days plus consistent long nights.
How Often Should You Water a Poinsettia?
Check the mix and the relative weight of the pot rather than following fixed weekdays or a set volume. When the surface starts to dry and the accessible root ball is no longer wet, water the nursery pot thoroughly and allow excess to drain. Remove the decorative cover for the job, empty collected water and check again before the next watering.
Open answerHow Do You Get a Poinsettia to Turn Red Again?
Grow a healthy plant, confirm its expected bract colour, then follow one complete autumn light-and-darkness routine. A practical Illinois Extension example uses uninterrupted darkness from 17:00 to 08:00, with bright daylight outside that period, starting in late September for its northern-hemisphere cycle. This is one protocol, not a universal biological threshold or a guarantee of Christmas colour.
Open answerWhat Should You Do With a Poinsettia After Christmas?
Keep sound leaves, provide bright daylight and water according to the root ball while the poinsettia remains green and healthy. Do not routinely dry it out in a dark cupboard because Christmas has ended. Consider pruning and repotting when the plant is healthy and entering active growth. A new coloured display is optional and needs a separate seasonal light routine.
