Toxicity
Greg does not have confirmed data on this plantâs toxicity. If you, a family member, or a pet consumes plant material of unknown toxicity, itâs always best to consult a medical professional.
If you or someone else ingested this plant, call Poison Control at US (800) 222-1222. If a pet consumed this plant, contact your veterinarian or the ASPCA at US (888) 426-4435.
Soil
Cnicus 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
Cnicus should be repotted after it doubles in size or once a year, whichever comes first. Fresh potting soil has all the nutrients your plant needs, so as long as itâs refreshed yearly, you shouldnât need to use fertilizer. Remember, plants get their energy from sunlight, not fertilizer!
