Some of the Streptocarpus are deciduous and a lack of light will cause yellowing of the leaves and drop-off. Have you checked out wikipedia? They may have some information for you.

Hello suzie what makes you think that ?lol x .

Spring in the air, do you mean, Noseypotter? Robins, sparrows and now blackbirds singing before the sun is up, crocus and daffodil in flower ... apart from the odd couple of days of frost the winter has been incredibly mild. As I said before, Suzie, check out the wikipedia site for your plant - very detailed and informative. Leave the leaves alone until they fall off or come away easily. There are so many varieties of this one, it is difficult to answer your question directly.

yes it has as it goes avkq47 i still cant weight for spring when i will of sprung lol into the garden that is lol .

Hi, thanks everyone for your comments. I will post a photo of the plants in question later today and perhaps it will clarify the problems. The streptocarpus are in the conservatory so they have as much light as possible.
Thank you x

your more than welcome .

Streptocarpus:

I have done some research and it is quite a common problem in winter, it is call an "abscission line" as the tip of the leaves die back but the base keeps growing.
As I am writing this it is snowing a blizzard, yuck (so much for spring - spoke too soon me thinks).

oops not to worry i doubt it will last long hopefully x .
