How to Grow Cat Grass Plant?

The peculiarity of the cat grass plant is that you can grow it indoors and outdoor. If you get direct sunlight outdoor and the temperature does not go below freezing point, you can grow the grass outdoors. In the case of indoor cat grass, you can plant it on a windowsill where bright sunlight is available. 

 Growing Cat Grass Plant Indoors

Cat grass is a fast grower and needs bright light for its healthy growth. 
  • Take the container where you want to grow the grass and fill it with soil. The soil should be ½ to 1 inch below the container’s rim. Now moisten the soil.
  • Take seeds from cat grass kits and moisten them. But do not soak it in water. Now scatter the seed on the soil. You can fill the container with the seed as the plant grows straight up. 
  • Cover the seeds with more soil and moisten them. 
  • Place the container in an area where bright sunlight is available. 
  • Mist the seed every day until sprouting takes place. 
  • Water the indoor cat grass once in 2-3 days.  

Growing Cat Grass Plant Outdoors

Cat grass is different than lawn grass. You should grow cat grass in the spring after all frost has subsided. Growing cat grass outdoors is easy and involves the following steps. 
  • Remove all the weeds and till the soil. Now level and smooth it. 
  • Sow the grain about ¼ inch deep into the soil. 
  • Moisten the soil well. 
  • The grain will sprout in 1-2 weeks. 

How to Care For Cat Grass Plant?

Cat Grass Plant is a mixture of grain grasses primarily composed of oat grass, wheat grass, barley grass and rye grass. Cat grass plant care involves the following. 


You should water cat grass once every two days. Check the top of the soil to see whether it is moist. Water the plant only when the soil moist level is low. Overwatering should be avoided at all costs as it can cause mold formation. 


Though cat grass requires abundant sunlight for healthy growth, you should avoid placing it in direct sunlight. This can result in the plant dying off due to overexposure to the sun. In the case of an indoor plant, place it on the windowsill with indirect, bright light where abundant sunlight is available. 


The ideal temperature for cat grass is 60-66 degrees Fahrenheit. You can keep it on a windowsill where you can maintain the temperature. But remember not to expose it to direct sunlight. As long as the plant has enough water content, it can take the rising temperature. But the plant cannot tolerate cold weather. Thus, once frost begins, you should bring the plant indoors if you're growing it outside.


Humidity is not a problem for cat grass. If the humidity levels are very high, you will notice the plant drooping. On the other hand, if the humidity level is low, you can use a spray bottle or humidifier and mist the plant. It is best to moisten the seeds before sowing them. 


Organic potting soil is best for growing cat grass. You can also use regular garden soil provided it can hold moisture. If you use a soil-less medium, you can opt for two-part coconut coir, half part vermiculite, and one part perlite. 

Cutting and Pruning

Once the grass blades have grown to around 5 inches tall, you can prune them with shears. This promotes new growth. You can sprinkle the cut portion on your cat's food or water. Make sure you use sterilized garden shears to avoid any bacterial infections.

How to Propagate Cat Grass Plant?

Cat grass is very easily grown from seed. Below are the steps for propagation
  • Fill the pot with organic potting soil. You should stop 1-2 inches from the top of the pot. 
  • Scatter the seed on the pot and cover it with some potting soil. 
  • Pour around ½ cup of water to keep the soil moist. 
  • Cover the pot with plastic wrap. It would help if you left a small opening for airflow. 
  • Keep the pot in a dark and warm location. The seed starts sprouting on the second or third day. 
  • Once the plant has grown a bit, you should remove the wrap and place it in a bright area. 

Common Cat Grass Plant Pests and Diseases

Like most other houseplants, cat grass is also not free from pests and diseases. Keep in mind that you should never use pesticides on cat grass as your feline friend feeds on the same. You can use neem oil to treat pests and diseases as it's not toxic to pets. Since most bugs do not harm cats, you need not worry if the grass is infested. 
Below are a few of the pests that can infest cat grass


  • Aphids: Aphids are sucking insects found underneath the leaves of the cat grass. They are either black, red, or green in color. Aphids leave a sticky residue on the leaves that can attract ants. The best way to get rid of aphids is to attract natural predators like lady beetles and wasps that feed on aphids. Use neem oil for natural treatment.
  • Armyworms: These are dark-colored worms that leave holes on the leaves, eventually making them skeletonized. You will notice a cotton-like covering on the leaves, which are the worm’s eggs. You can use neem oil to treat and make sure to pick off all the armyworms off and wash the plant to wick away any larvae. Another way to get rid of them is to use natural enemies. But these enemies can be dangerous for your pet. If the infestation is unmanageable, it is best to throw away the grass. 
  • Whitefly: These are white-colored flies that fly up when you disturb the grass. You can try neem oil to control them. If it does not work, it is best to throw away the grass.
