Troubleshooting
Yellow Gesneria problems — and how to fix them
Yellow Gesneria (Gesneria citrina) 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.
Poor flowering in low light
As a hummingbird-pollinated species, Gesneria citrina requires strong bright light to trigger bud set. Supplemental LED grow lighting of 12–14 hours daily markedly improves flower production indoors.
Root rot from overwatering
Wet, dense soil quickly rots roots in this warm-growing species. Ensure excellent drainage, use a light mix, and allow the top of the compost to dry slightly between waterings.
Low humidity damage
In dry indoor air, leaf margins turn brown and crisp. Maintain humidity above 60% using a pebble tray or humidifier; avoid placing near heating vents or air conditioning.
