root rot on Mammillaria Plumosa
Quick answer
If your Mammillaria Plumosa has root rot, the most likely cause is: Clive Innes's complete handbook of cacti and succulents names root rot as one of the most prevalent difficulties for the cactus family that includes Mammillaria plumosa, and ties it to watering errors: giving a teaspoonful every day keeps the compost perpetually wet, and on the other hand letting the root system dry out completely so the roots shrivel and then rot when water is renewed.
Start here:
- 1. Water well only when the compost has actually dried, never applying water while it is still moist, so the roots are not kept in a saturated medium that invites root rot.
- 2. During the cool rest period give only enough water to keep the root system just moist, never wet, so the roots do not dehydrate then collapse and rot when watering is renewed.
