spider mites on Mammillaria Grahamii
Quick answer
If your Mammillaria Grahamii has spider mites, the most likely cause is: Eight-legged spider-mite arthropods are so small that their damage generally shows up before the pests themselves; they form fine, dense webbing over Mammillaria grahamii stems and destroy the epidermis as they feed, leaving an infested plant lighter in colour and eventually silvery-yellow, with extensive scarring on the youngest growth around the hooked-spine tubercles.
Start here:
- 1. Inspect neighbouring cacti upwind and downwind from an infested Mammillaria grahamii to locate the source and any new colonies, since mites drift into a collection on a breeze of silk.
- 2. Apply a miticide following the label directions closely and plan on multiple treatments, since one application is virtually never 100 per cent effective against either the mites or their eggs.
