How do you take care of Cat grass?


Cat grass grows best on a location with medium light to partial shade. They like shade better than direct sunlight. Direct sunlight will kill the plant rather than do it any good.


Water the cat grass regularly. About once a week to every 10 days is enough. It is not necessary to keep the soil continuously moist. We do, however, recommend placing the plant in a flowerpot with a saucer. This prevents wet feet and eventually root rot.

Repotting Cat grass is not necessary. Most cats enjoy Cat Grass so much that the plant becomes bald really soon.


The most ideal temperature for growing Cat grass is between 15 to 24 degrees Celsius. It thrives in moderate temperatures and can be grown indoors or outdoors.


Pruning Cat grass is not necessary for its growth. However, regular pruning helps to remove any yellowed or dried-out blades of grass and encourages fresh growth. Pruning also helps to ensure that the cat has access to fresh and tender grass blades, which they often prefer to eat.
