Small batches, steady harvest
Sow fast crops (lettuce, radish, beans) in small batches every 1–3 weeks rather than all at once. When one batch finishes, replant the space with a different family if you can, to reduce pest and disease build-up. Keep a simple notebook of sowing dates — that record is worth more than any app for next year. Use the seed quantity calculator per batch, not for the whole season at once.
