Colocasia Antiquorum problems — and how to fix them
Colocasia Antiquorum (Colocasia antiquorum) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Leaf-edge scorch
Brown crisping margins signal the soil dried out or humidity is too low; this plant will not tolerate drought.
Stunted or small corms
Too little sun, a short cool season, or insufficient feeding produces tiny corms; give full sun, a long warm season and rich soil.
Spider mites in dry air
Indoors or in arid heat, stippled, dusty undersides indicate mites; raise humidity and rinse foliage.
Corm rot in cold wet soil
Although it loves water, cold standing water in winter rots dormant corms; lift and store corms dry in zones below 8.
