Care of alocasia or arrow leaf

  • Proper care of Hebe or shrub veronica

Spray the leaves with water more often to increase the humidity.

When and how is the arrow sheet fertilized?

It is fertilized every two weeks from April to September. Use a regular fertilizer for foliage plants. Cut the indicated dose in half.

Do you need to cut alocasia?

You are allowed to cut the arrow leaf when the plant has grown too big. It's best to do this in the spring. Cut the shoots back to two thirds.

You can remove dead leaves as well as the flower.

What should be considered when repotting?

When the roots of the Alocasia have completely rooted the substrate, you should repot them, in early spring.

Put them in a larger pot that you have previously filled with loose potting soil or a mixture of leaf soil, gravel and clay granules. Create a drain in the bottom of the pot to prevent waterlogging.

Which diseases and pests can occur?

If the substrate is permanently too moist, the roots will rot. In addition, Alocasia is susceptible to various pests:

  • Whiteflies
  • Thrips
  • Spider mites

Check the plant regularly for infestations and take control measures immediately.

How do you care for alocasia in winter?

Alocasia is cared for in the room all year round. The temperatures must not fall below 15 degrees even in winter. Water a little less in winter, but make sure that the humidity remains high enough.


The arrow leaf belongs to the arum family and, like all members of this plant family, is poisonous. The milk juice can cause skin irritation. You should therefore avoid an alocasia if there are small children or pets.
