🌿 Your First Seed Sowing of the Year: What’s Safe and What’s Too Early



February is the month when seed packets start calling to you. You open the tin “just to check what you’ve got,” and suddenly you’re halfway to sowing tomatoes on a windowsill that barely gets light.

The truth is simple: you can sow a few things now — but most seeds need you to wait. This is the honest guide to what’s safe, what’s risky, and how to avoid the classic February mistakes.

Seeds you can start now

These are the seeds that genuinely cope with low light and cool conditions. They won’t sulk, stretch, or collapse.

  • Broad beans (if you didn’t autumn‑sow)

  • Chillies (the slow ones — they need the head start)

  • Onions from seed

  • Leeks

  • Hardy herbs like parsley

  • Sweet peas (if you haven’t already)

These are slow, steady growers. They don’t mind taking their time.

Seeds you shouldn’t start yet

This is where most February enthusiasm goes wrong.

Avoid sowing:

  • Tomatoes

  • Peppers (unless you’re growing super‑hots)

  • Courgettes

  • Squash

  • Cucumbers

  • Runner and French beans

  • Anything that says “needs warmth and good light”

These will germinate, stretch, and then spend the next six weeks trying to die gracefully.

If you want to save yourself the heartbreak, the Tools You Don’t Need Yet post (No. 2) explains why greenhouse heaters and early trays don’t help.

Why light levels matter

February light is improving, but it’s still weak and short. Plants don’t just need warmth — they need energy.

Low light creates:

  • long, pale stems

  • floppy seedlings

  • plants that can’t support their own leaves

  • seedlings that fail the moment you harden them off

If you’ve ever wondered why your early sowings look like they’re trying to escape the pot, this is why.

How to avoid leggy seedlings

You don’t need special kit — just good habits.

  • Sow thinly

  • Keep seedlings as cool as the variety allows

  • Turn trays regularly

  • Give them the brightest spot you have

  • Don’t overwater

  • Don’t rush to pot on

If you’re tempted to buy lights or heaters, remember: February rewards patience more than equipment.

A simple windowsill setup

You don’t need a mini‑greenhouse or a heated propagator.

A good February setup is:

  • a bright windowsill

  • a tray to catch drips

  • a few modules or small pots

  • a clear cover you can remove once seedlings appear

  • a notebook to record what you sowed and when

If you’re unsure what tools are actually worth having, the Tools post on the Allotmenteer blog keeps things refreshingly simple.

The real rule of February sowing

Sow the slow, hardy things. Wait for the rest.

If you get February right, March and April become a joy instead of a rescue mission.
