Hi I sowed melon seeds in modules in a heated sunroom 3 weeks ago no sign of a single germination from 15 seeds. It issue last years seed though still in date. Is it just too old or does anyone have any other tips?
I would suspect they are too cold. Instruction with my seed from Real Seeds suggests 25C. My squash, melon, cucumber and courgette seed certainly shot up in a few days at this temperature. I doubt they are too old: once again some info gleaned from Real Seeds – the seed saving instructions suggest they are good for 10 years
Have you got any more of the seeds? Try soaking for a few hours, then place in a poly bag in the airing cupboard for a few days, checking twice a day. Once they show signs of sprouting, gently plant and return to the cupboard. Check twice a day.Once cotyledons visible above surface, expose to light in warm (24 hr above 15deg C) window cill location.
