Shining Sinningia problems — and how to fix them
Shining Sinningia (Sinningia micans) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Failure to flower despite healthy tuber
Allowing too many growth points to develop causes the tuber to put energy into foliage rather than blooms; pinch back to one or two shoots when growth begins to encourage bud set.
Fungus gnats in soggy compost
Larvae damage fine roots when compost is kept too wet; allow the top layer of compost to dry slightly between waterings and use yellow sticky traps to monitor adult populations.
