Guide at a glance
  1. SeedsSuit direct-sown crops and need germination care.
  2. Check originUse traceable, compliant planting material.
  3. Young plantsSave early time but still need the right season.

Use seed when direct sowing protects the root

Carrots, radishes and several legumes are often simpler when sown where they will finish. The seed packet remains the primary instruction for cultivar depth, spacing and current treatment information.

Use young plants to save early time, not to bypass season

A sturdy young plant can shorten protected propagation, but it still needs suitable frost risk, soil warmth, light and remaining maturity time. Avoid root-bound, damaged or unidentified material.

Check origin and the relevant UK rules

Plant-health arrangements differ between Great Britain and Northern Ireland and can change. Check current official rules before bringing, posting or ordering plants, seeds, soil or other regulated material.

Harden off gradually

Increase exposure to outdoor light, wind and temperature in controlled steps. Bring plants back to safety when conditions exceed the plan rather than treating one exposure as proof of hardiness.
