Troubleshooting
Mackay's Zygopetalum problems — and how to fix them
Mackay's Zygopetalum (Zygopetalum mackayi) 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
Dark necrotic spots on the soft foliage are typical of the genus and largely cosmetic, aggravated by wet leaves and stagnant air. Water at the roots, keep foliage dry, and improve airflow.
Reluctant flowering
Leafy but flowerless plants need more light and feeding. Provide bright Cattleya-level light and feed regularly during growth to trigger spikes.
Pleated new leaves
Accordion folds in fresh growth signal the plant dried out or humidity fell while growing. Keep evenly moist and humid through the growing season.
Salt build-up and tip burn
Hard water and heavy feeding scorch leaf tips. Use low-mineral water, feed at half strength, and flush the mix monthly.
