Toxicity
Sourgrass is not safe to consume. If you, a family member, or a pet has ingested any amount of plant material contact Poison Control, US (800) 222-1222, or your veterinarian. If you have children, cats, or dogs in the home, we suggest keeping this plant out of reach.
Humidity
Sourgrass doesnāt require additional humidity. Plants absorb most water through their root system rather than their leaves, so the best way to provide humidity for your plants is through watering the soil.
Soil
Sourgrass does best in well-draining soil. A good soil will contain lots of organic matter such as coco coir as well as perlite or vermiculite to help with drainage. Adding a handful of perlite to regular store-bought potting soil should do the trick!
Fertilizer
Sourgrass grows very slowly and doesnāt require added fertilizer. Replacing your plantās potting soil once a year should provide them with more than enough nutrition. Remember, plants get their energy from sunlight, not fertilizer!

Growth Pattern
Sourgrass grows vertically and new growth will emerge from the top of the plant.
