Poinsettias are one of those festive favourites that brighten up our homes over Christmas, but with the right care, they can stay lush and colourful long after the holidays have passed. The secret? Getting the watering just right.

How often to water

Your poinsettia will tell you when it needs a drink – you just have to pay attention. Water only when the top layer of soil feels dry to the touch. Simply press a finger into the soil; if it feels dry about a centimetre down, it’s time to water. On average, that’s about once a week, but it can vary depending on your home’s light, temperature, and humidity levels. 

The right way to water

Pour water slowly over the soil until it begins to drain out the bottom of the pot. Allow any excess water to run off completely before putting the plant back in its saucer. Avoid letting your poinsettia sit in standing water – soggy roots are a quick way to kill it. Also, try not to splash the leaves; they prefer to stay dry. 

What affects how often you water

Light: A poinsettia placed in a sunny spot will need more frequent watering than one tucked away in a cooler, shadier corner. 

Soil: Most store-bought poinsettias come in a peat-based potting mix that holds moisture well. If yours is in a sandier mix, it may dry out quicker. 

Pot size: Small pots dry out faster than large ones, so check them more regularly. 

Temperature: Poinsettias like a steady environment. Avoid placing them near heaters, fireplaces, or cold draughts, as sudden temperature changes can cause stress and leaf drop. 

How to spot a thirsty poinsettia

If the leaves start to droop or look limp, your plant needs water. Don’t wait too long to fix it – once the leaves wilt repeatedly, they can fall off. 

When it’s had too much

Yellowing leaves or a heavy, soggy pot are signs of overwatering. If the roots sit in wet soil for too long, they’ll rot, and the plant will struggle to absorb water properly – causing even more wilting and leaf loss. 

A few extra tips

  • Always use a pot with drainage holes. 
  • Turn your poinsettia every few days so all sides get equal light. 
  • Keep it in a bright, warm spot, but out of direct sunlight. 

With the right balance of water and light, your poinsettia can stay vibrant long after the last Christmas decoration comes down – and maybe even bloom again next year.
