How to Care for Cyperus (Umbrella Grass) – Expert tips for thriving plants

Cyperus alternifolius ‘Zumula’, often called Umbrella Grass or Umbrella Plant, is a playful houseplant with thin, grass-like leaves that grow in little umbrella-shaped clusters. Its fresh green colour and airy structure give your home a light, tropical look.

This plant originates from wetlands in Madagascar, which explains why it loves water more than most houseplants. Cyperus ‘Zumula’ grows quickly and is a great choice for bright windowsills, plant shelves or even bathrooms where humidity is higher.

5. Feed your plant once a month during spring and summer.
6. Keep temperatures between 18–25°C for best growth.
7. Cyperus enjoys higher humidity levels.
8. Trim yellow or dry stems to keep the plant looking fresh.

10. Check the plant occasionally for pests.

Cyperus care tips

Light requirements for Cyperus

Cyperus ‘Zumula’ grows best in bright, indirect light but can tolerate a little direct sun. A spot near a window with plenty of natural light is ideal.

Too little light can cause the plant to grow slowly or become less full.

Expert tip! If the stems start leaning or stretching, your Cyperus may need more light.

Watering

Cyperus is very different from most houseplants when it comes to watering. It naturally grows in marshy environments, which means it prefers consistently moist soil.

Water your plant regularly and make sure the soil never dries out completely.

Expert tip! Cyperus actually enjoys standing in a small layer of water. Placing the pot in a saucer with water can help keep the soil moist.

Nutrition

During spring and summer, feed your Cyperus with a balanced liquid houseplant fertiliser once a month. This supports healthy growth and helps the plant produce fresh stems.

In autumn and winter, fertilising is usually not necessary.

Expert tip! Because Cyperus grows quickly, occasional feeding helps maintain its vibrant green colour.

Temperature & humidity

Cyperus grows best in warm temperatures between 18–25°C. It also enjoys higher humidity levels, which makes it a great plant for kitchens or bathrooms.

Avoid placing the plant near cold drafts or heaters, as sudden temperature changes can stress the plant.

Soil & repotting

Cyperus prefers rich, moisture-retaining soil. Regular houseplant soil works well as long as it holds moisture but still drains properly.

Because the plant grows quickly, repotting every 1–2 years is recommended. Choose a pot slightly larger than the current one so the roots have room to grow.

Propagating Cyperus

Cyperus ‘Zumula’ is very easy to propagate and grows quickly from divisions or stem cuttings.

Here’s how to do it:

1. Cut a healthy stem just below the leaf cluster.
2. Turn the stem upside down and place the leafy top in water.
3. After some time, small roots and shoots will begin to grow.
4. Once roots have formed, plant the cutting in moist potting soil.
5. Keep the soil consistently moist while the new plant establishes.

Cyperus can also be propagated by dividing larger plants when repotting.

Most common pests on Cyperus

Cyperus is generally a strong plant but can occasionally attract pests such as spider mites, aphids or scale insects.

Regularly checking the stems and leaves helps catch any issues early. Keeping the plant well-watered and clean will also help prevent pest problems.

Is Cyperus poisonous for your pets or children?

Cyperus alternifolius ‘Zumula’ is generally considered non-toxic to cats and dogs. In fact, some pets may even enjoy nibbling on the grass-like leaves.

However, it’s still best to discourage pets or children from eating houseplants.
