February sown sweet peas build deep roots and flower earlier. Here’s a no‑fuss method—root trainers vs. pots, pinching, feeding, and hardening.
Sowing Method (2 Ways)
- Root trainers / tall modules: 1–2 seeds per cell, 1.5–2 cm deep.
- Pots: 9 cm pot, 4–5 seeds; transplant as a clump to minimise shock.
Light & Temperature: Bright, cool (10–15°C) to avoid legginess.
Pinch tips at 3–4 pairs of leaves for bushier plants.
Feed lightly once growing on; avoid excess nitrogen.
Harden in a cold frame before planting out.

Supports & Spacing
- Train on netting, obelisks, or pea sticks; 30 cm apart.
- Keep roots cool with mulch; water consistently through dry spells.
Pollinators & Cutting
- Sweet peas draw bees early; regular cutting extends flowering.
- Remove spent blooms to prevent pod formation and slowdown.

FAQs
Do I need to soak seeds?
Optional; nicking a hard seed coat can help, but fresh seed usually germinates well.
Can I autumn‑sow instead?
Yes—autumn sowing is great in mild regions; February is the safer universal window.
Why are my plants leggy?
Too warm/low light—move to cooler, brighter conditions and pinch.
