I have had my Coral Cactus for approx 4 years. Noticed brown spots developing on the fan part of cactus..never noticed this before. I am wondering what is the cause and what I can do to fix it enter image description here

  • Good question; if could include an overall illustration & closer illustration of the discolorations, overall height, stem diameter, current watering amount & frequency, current nutrient amount & frequency, sunlight hours it receives, if some coarse gravel in the bottom and a hole in the bottom for good aereation & drainage, average daytime temperature, and average night time temperature, could also be helpful. We encourage you to take the Tour, and browse through the Help center to learn more about how the site works! Thank you! Welcome to the site!
