A useful place to start
Follow the plant from seed to establishment.
Start with the crop’s germination requirements, plan its indoor space, then ease it into outdoor conditions.
01 / Choose the sowing window
Work backward from your frost date to start seeds
Count back from a locally appropriate transplant target, then check the crop’s germination requirements.
02 / Check dormancy needs
Cold Stratification or Scarification? Match the Treatment to the Seed

03 / Choose the growing space
Match Seed Cell Size to the Crop, Its Schedule, and Your Available Space
Match cell size and potting-on time to the roots you are raising.
04 / Prepare for the garden
