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.
Humidity
Coastal Onion doesnât 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
Coastal Onion 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
Coastal Onion 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!
Native Region
Coastal Onion is native to the Northern Hemisphere, South America, and Africa.
Growth Pattern
Coastal Onion grows vertically and new growth will emerge from the top of the plant.
