Succession sowing at 2-3 week intervals extends harvest for short-DTM crops.
Promising · suboptimal if ignored → advise
How it works
Sowing the same crop in batches two to three weeks apart staggers when each batch matures, so the harvest arrives as a continual succession instead of one glut. It pays off only for short-DTM crops, whose quick turnaround lets several sowings ripen within a single season.
