Zygopetalum mackaii problems — and how to fix them
Zygopetalum mackaii (Zygopetalum mackaii) 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.
Crown and leaf rot
Water lodged in the crown or on the pleated leaves causes black soft rot. Always water in the morning, keep the crown dry, and ensure good air movement.
Black fungal leaf spots
Dark spots on the foliage are common in still, humid air or with hard water. Improve airflow, water with low-mineral water, and remove badly affected leaves.
Accordion-pleated new leaves
Like its relatives it pleats when watering is uneven during growth. Keep moisture steady while new growths expand.
Reluctant flowering
Too little light or no cooler winter dip suppresses blooms. Brighten the light and allow a modest seasonal temperature drop.
