When would you recommend David? I have never sown in autumn before so not sure of the best time?
There really isn't an exact time.....it's broadly accepted that sowing should be done in the autumn, but then, it isn't even autumn yet.
I tend to sow according to the prevailing weather conditions rather than a specific time. The best case scenario is to sow when there is still sufficient warmth to germinate the seed followed by cold weather to prevent them putting on growth. This could be as late as November.
