Everything I'm about to share is book knowledge @seedcorn, not my own practices, as I can't save chard seed in my climate because it won't overwinter here, and can't really be dug up & stored for the 2nd year. But I do believe you need to wait until the stalks and seed itself is quite dry on plant. It needs to mature in place fully, and then you collect. Important is that beets weren't grown within 1/2 mile of it, as chard is not self pollinating and will cross with it. The seeds are are actually multiple seed bundles, so be careful not to break 'em apart when you're threshing. I'm not sure about the length of time for the seeds to ripen though, with the biennials some are quicker than others. I think it's also dependant on how early you planted the previous year, and your current seasons' weather. 'Midsummer' for dry seed in the Northern states, so says the books.Last year’s Swiss chard is now loaded with green seed. How long till it will mature so I can harvest and remove the plants?
