What's eating my crassula hemisphaerica?

Crassula Hemisphaerica (pagoda crassula) is most vulnerable to mealybugs lodging between its stacked, tightly-packed leaves. Root mealybugs silently attack the roots, and spider mites appear in low-humidity rooms. The compact architecture makes pests hard to spot — inspect stem crevices closely and treat at the first sign of white wax.

White cottony deposits between tightly stacked leaf pairs; stunted growth; honeydew Use a fine cotton swab dipped in 70% isopropyl alcohol; follow with diluted neem oil spray; repeat weekly

Wilting and leaf drop despite correct watering; white powder on roots when unpotted Remove from pot, wash roots, soak in diluted neem drench, repot in fresh fast-draining mix

Fine webbing at leaf margins; pale stippling on upper leaf surfaces Improve airflow and humidity; spray with insecticidal soap or diluted neem oil; repeat every 5–7 days
