February Heat‑Lovers: How to Sow & Grow Tomatoes, Peppers & Aubergines Indoors (UK)
Begin your summer harvests now. February is prime time to start tomatoes, peppers/chillies and aubergines indoors — but only if you can supply constant warmth and strong light. Here’s the step‑by‑step for reliable germination, sturdy seedlings, and smooth transplanting into your greenhouse when frosts are past.
Step‑by‑step Sowing
- Containers & compost: Fine seed compost in clean modules; lightly firm.
- Sow & cover: Surface‑sow, then a dusting of vermiculite/compost.
- Heat: Keep consistently warm (propagator/heat mat) — vital for aubergines and chillies.
- Light: From emergence, give bright south‑facing light or grow lights to prevent legginess.
- Moisture & air: Even moisture; ventilate to prevent damping off.
Grow‑on & Potting Up
- Prick out at first true leaves; gentle handling of stems.
- Pot on as roots reach edges; don’t let plants stall.
- Harden in stages via cold frame before the greenhouse move.
Troubleshooting
- Leggy seedlings → insufficient light; lower lights/boost lumens.
- Slow germination (aubergine/chilli) → increase bottom heat; be patient.
