Maritime Zamia problems — and how to fix them
Maritime Zamia (Zamia maritima) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Root and caudex rot from overwatering
The most common cause of death. A soft, discoloured caudex base indicates rot. Remove from soil immediately, cut away all affected tissue with a sterile blade, dust with sulphur fungicide, and allow to dry for several days before repotting in fresh, dry gritty mix.
Scale insect infestation
Armoured and soft scale insects cluster on the underside of leaflets and along the rachis, causing yellowing and weakened fronds. Treat with horticultural oil or neem oil applied to all frond surfaces. Severe infestations may warrant systemic insecticide.
