Troubleshooting
Miniature Sinningia problems — and how to fix them
Miniature Sinningia (Sinningia pusilla) 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.
Drying out in open air
Its tiny size means it desiccates fast outside a humid enclosure. Grow it in a covered terrarium or jar to keep humidity high and stable.
Tuber or crown rot
Excess water around the small tuber rots it. Keep the mix lightly moist, never saturated, and ensure the medium is airy.
Stopping flowering
Too little light or low humidity halts the near-constant bloom. Provide bright indirect light or a grow light and maintain a humid environment.
Mould in the terrarium
Stagnant, over-humid air can encourage fungal growth. Give occasional ventilation and remove any spent flowers or decaying leaves promptly.
