Colocasia Care Guide – Everything You Need to Know

Colocasia, often called Elephant Ear, is a stunning tropical plant known for its bold, dramatic foliage. Popular among UK gardeners for its exotic look, Colocasia can transform any garden into a lush paradise. But how do you grow it successfully in the UK climate?

Is Colocasia Hardy in the UK?

Colocasia is not fully hardy in most parts of the UK. It thrives in warm, frost-free conditions, so it needs protection during colder months. In mild coastal areas, some varieties may survive outdoors with heavy mulching, but generally, it’s best treated as a tender plant.

How to Overwinter Colocasia in the UK

To keep your Colocasia healthy through winter:

Step 1 – Lift Before Frost

Lift the plant before the first frost to prevent damage.

Step 2 – Trim and Store Tubers

Trim back foliage and clean the tubers. Store them in a cool, frost-free place (around 5–10°C) in slightly damp compost or peat.

Step 3 – Pot Indoors

Alternatively, keep the plant in a pot and move it indoors to a bright, frost-free spot.

What Is the English Name for Colocasia?
