Streptocarpus 'Targa' problems — and how to fix them
Streptocarpus 'Targa' (Streptocarpus 'Targa') 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
Typically too little light or no feeding. Brighten the position (indirect) and feed regularly with high-potash fertiliser in the growing season.
Crown and root rot
From overwatering or water in the crown. Water at the soil edge, allow the surface to dry, and use a free-draining mix and pot.
Scorched leaf edges
Direct sun damages the soft foliage. Filter the light or move away from hot south windows.
Limp, chilled foliage
Temperatures below about 12°C or cold draughts. Keep in a warm, stable spot, especially in winter.
