Help! I think I killed my cacti or succulent!
Both are hardy plants. They can handle much neglect and still flourish but WHOOPS you over watered it.
Thank you for not giving up your cactus baby. Mistakes happen!
To rid your cacti of brown spots, simply cut them off by using a sharp sterile knife to dig out the damaged flesh and allow the hole to dry out. Rotting can be caused by a fungus so check the soil to see if it is soaked. If it is, repot the cacti in a porous soil mix and let the plant dry out.
If the roots are infected, carefully dig out your cactus without damaging or pulling the roots. Wash the Cacti roots thoroughly and cut the dead roots off (soft black roots or dried-up roots that appear dead). Please note to cut just up to the part of the root that appears to be living. Afterward, let the cactus sit for about a week out of its soil. You want your freshly cut roots to form a callus over them. Let the cactus roots sit out of the sun in a cool environment. Afterward, you may repot. Replace the diseased soil with new, clean, porous soil mix. It is important to use a terracotta pot that is appropriately sized for your cactus to help avoid overwatering
If your cactus appears to be mushy, take the non-mush part cuttings and let them root into a new cactus. You must allow the callus to dry completely before inserting it into sand or porous soil mix. Please note that the roots will take almost 2 months to appear. This is called propagation. A new baby cacti friend will appear for you to enjoy.
