Streptocarpus 'Harlequin Blue' problems — and how to fix them
Streptocarpus 'Harlequin Blue' (Streptocarpus 'Harlequin Blue') 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.
Sparse flowering
Lots of leaves but few blooms result from low light or excess nitrogen. Increase bright indirect light and feed with a high-potash formula.
Root and crown rot
Soggy soil or a wet crown causes rapid collapse. Allow the surface to dry between waterings and water at the soil edge.
Brown leaf tips
Hot, dry air, heat stress or salt build-up scorch the foliage. Raise humidity, keep cool below 25°C and flush the soil now and then.
Leaf scorch
Bleached, crisp patches follow direct sun. Move the plant to bright but filtered light to protect the soft leaves.
