can rape grow well in winter?

Well not being a farmer, I can only guess. In our area, winter wheat is sown, but never rape. It always grows and flowers at about this time of year, so I reckon the answer is probably 'no'.

I see that Thamson lives in Zambia so, assuming he is talking about oil seed rape, I would suggest that the best source of information would be the Zambian Agricultural advisory service.

Whoooppps! Well spotted, Bulbaholic! I missed that! Sorry, Thamson.
