Hairy Kohleria problems — and how to fix them
Hairy Kohleria (Kohleria hirsuta) 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.
Rhizome rot
Overwatering during the growing season or keeping rhizomes too wet during dormancy causes rot. Let the soil dry more between waterings and store dormant rhizomes in slightly moist (not wet) perlite or compost over winter.
Leggy, weak growth
Insufficient light causes Kohleria to stretch toward the light source, producing weak stems and few flowers. Move to a brighter position or add grow-lights. Pinching tips early in the season promotes bushy growth.
Thrips
Thrips can damage flowers and leave silvery streaks on hairy foliage. Inspect new growth and flowers regularly. Treat with spinosad or insecticidal soap, repeating applications weekly for three to four weeks to break the pest cycle.
