Swiss chard through the year
Against the frost risk in Victoria
Why these dates
One spring sowing usually lasts until hard frost. In mild climates it overwinters and produces an early spring flush before bolting.
Takes -5C without protection. Under a cloche it will hold through much colder weather and resume growth in late winter.
Seed packets and extension guides express timing as weeks either side of the last spring frost, because that is the only reference point that travels. Swiss chard are timed from 5 weeks before that frost for an indoor start, with planting out 1 weeks before it, and this page simply resolves those offsets against the frost date computed for Victoria.
The median frost-free season here is 294 days, against 50 to 60 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
