I’m aware of spring fairs coming up for local groups for each of the next three weekends, where plants will be on sale. They are often a way local gardeners get rid of surplus seedlings and cuttings and support a cause they believe in, and for those without the time, inclination or greenhouses, a chance to pick up plants cheaper than they might from a garden centre.
Anyway - here’s my current listing, but please anyone else add to it
Saturday May 6th, 11 - 3 pm, Sydenham Garden Spring Fair, Wynell Road, SE23
Saturday May 13th, 11 - 2 pm, Forest Hill and Sydenham CND Spring Plant Fair, Venner Road Hall, Venner Road, SE26
Sunday May 21st, 11- 3 pm, Kent House Leisure Gardens Open Day, 91/93 Kent House Road, SE26
Reminder that Kent House Leisure Gardens has its open day today , 11 till 3. Plants for sale, plus usually local honey, burgers, books, bric a brac, cakes plus a chance to look around this large allotment site.
