How to fertilize Bishops Cap

Most potting soils come with ample nutrients which plants use to produce new growth.

Thereās something wrong with my Bishopās cap cactus and I donāt know what to do I just noticed today that thereās a dark spot on my Bishopās cap cactus. Itās extremely squishy and it looks like thereās a ring of brown around the darker, squishy spot. Itās pretty big too, it goes about halfway around my cactus and at one point reaches about halfway up his side. What can I do? What have I been doing wrong? Can someone please help?

š¶ š š¶ Toxicity
Greg does not have confirmed data on this plantās toxicity. If you, a family member, or a pet consumes plant material of unknown toxicity, itās 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 atĀ US (888) 426-4435.
šØ Humidity
Bishops Cap prefers dry environments. Providing extra humidity or misting your plant allows water to linger on leaves, which can create the perfect environment for harmful types of fungi.
šŖ“ Soil
Bishops Cap is very sensitive to wet soil, so choose a potting soil that drains very well and doesnāt retain too much moisture. A good soil will have lots of perlite or vermiculite for drainage and some organic matter for nutrition. A few handfuls of perlite added to regular store-bought cactus soil will do the trick!
š© Fertilizer
Bishops Cap 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!
š Native Region
Bishops Cap is native to North America.
šø Flowers
Bishops Cap produces flowers in the wild, but does not flower when kept as houseplants.
š§ Troubleshooting
When troubleshooting a sad-looking houseplant, start by checking for signs of distress in its leaves, such as yellowing, browning, or drooping, which can indicate overwatering or nutrient deficiencies.
Inspect the soil moisture; too dry or too wet soil can cause problems.
Ensure the plant is getting the right amount of light, as too much or too little can stress it.
Finally, consider environmental factors like temperature and humidity, and adjust care routines accordingly to revive your plant.
