I went to a dayschool on sowing seed and received a comprehensive list of when is the best time to sow in Bristol and the only suggestion for sowing from mid-Jan. onwards were Bergenia semperflorence, Canna,Gazania and Sweet Pea. The earliest veg. was mid-late Feb. for broad bean, early cultivars of sprouts, ditto cabbage, calabrese,cauliflower, lettuce, onions, peas(early cultivars) But I already have well-grown lettuce which I sowed in the conservatory before Xmas and basil seedlings. It's fun to try and seed is not too expensive 'tho my friend has just spent £150 on seeds for her allotment! Aubergine,pepper,tomato all need heated glasshouse in mid-late Feb. in Bristol. Good luck for a great crop, Kate.
