Does each planting of a succession get its own days to maturity?

Yes, with Use climate-adjusted DTM on: each planting gets the days to maturity of its own date, so your April and July sowings no longer share one number and each harvest lands on the right week. Without it, every planting of a succession keeps the same days to maturity.

When late plantings fall outside the good weeks, the message in the planting window gives the date from which the succession’s days to maturity have been capped, so you know which plantings to question. See Use climate-adjusted days to maturity in a planting.
