Environment & Pre‑treatment

No stratification or scarification required for most common garden vegetables; maintain appropriate temperature and moisture for reliable germination.

Stratification = a cold, moist period that breaks dormancy. Scarification = nicking/scratching seed coat or hot‑water soak to speed sprouting.

Planting instructions

Sow at the listed depth and keep the seedbed evenly moist until emergence. Transplant only after hardening off; grow in full sun and well‑drained soil.

Detailed planting instructions

Use the temperatures and spacing in At‑a‑glance. Keep moisture steady (≈1 in/week); mulch to reduce swings. Protect from cold/heat with row cover or shade cloth as needed; remove cover at bloom for pollination. Feed modestly with compost or balanced fertilizer to maintain steady growth.
