Zygopetalum 'Redvale' problems — and how to fix them
Zygopetalum 'Redvale' (Zygopetalum 'Redvale') 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.
Black leaf spotting
Brown-to-black necrotic spots on the soft leaves are common and usually cosmetic, worsened by water sitting on foliage and poor airflow. Water at the roots, keep leaves dry, and improve air movement.
No flowers
Lush growth without spikes means insufficient light or feeding. Give brighter (Cattleya-level) light and feed regularly through the growing season.
Accordion-pleated new growth
Folded new leaves indicate the plant ran too dry or humidity dropped while growing. Keep evenly moist and humid during active growth.
Salt and tip burn
This heavy feeder still suffers from hard water and salt build-up; flush the pot monthly with low-mineral water and feed at half strength.
