January is quiet on the surface, but it’s one of the most important months in the gardening calendar. The days are short, the soil is cold, and the garden is resting — which gives you the perfect chance to plan, prepare, and set yourself up for a calm, successful year of growing. Think of this month as your reset button: slow, steady, and full of possibility.

Jobs for the Garden

  • Sort through your seed tin and make a simple plan for the year.
  • Clean pots, seed trays, and tools — it prevents disease later.
  • Check stored crops (squash, potatoes, apples) for any signs of rot.
  • Brush snow off shrubs if it settles heavily.
  • Order seeds early to avoid missing favourites.

This is a low-pressure month. Anything you do now is a bonus for later.

Seeds to sow this month

Vegetables

  • Onions & leeks — Start indoors for a long, steady growing season.
  • Chillies & aubergines (if you have warmth and light) — They need a long head start.
  • Microgreens — Fast, easy, and perfect for windowsills.

Flowers

  • Sweet peas — Can be sown now in a cool, bright spot.
  • Hardy annuals (cornflowers, calendula) — Only if you have a cold frame or unheated greenhouse.

Herbs

  • Parsley — Slow to germinate, so January is ideal.
  • Chives — Easy to start indoors for early growth.

Seedlings & Young Plants

If you’re starting early seeds indoors:

  • Give them as much light as possible — a bright windowsill or grow light.
  • Keep compost just moist, not wet.
  • Rotate trays so seedlings grow straight.
  • Don’t worry if germination is slow — January light levels are low.

This is a month for patience, not perfection.

Indoors, Greenhouse & Windowsill Growing

A sunny windowsill is enough for onions, leeks, and herbs.

If you have a greenhouse, keep it ventilated on mild days to prevent mould.

Protect anything tender with fleece on frosty nights.

Avoid sowing too much too early — light levels, not enthusiasm, decide success.

Harvesting in January

Depending on what you grew last year, you may still be picking:

  • Kale
  • Leeks
  • Parsnips
  • Winter salads in a greenhouse or cold frame

Everything grows slowly now, so harvest sparingly to keep plants going.

Wildlife & Garden Care

January is tough for birds and beneficial insects.
A few small actions make a big difference:

  • Keep bird feeders topped up.
  • Put out fresh water daily.
  • Leave some seedheads standing for shelter and food.
  • Avoid over-tidying — a little mess is habitat.

Nic's Tip Of The Month

Choose one small gardening task each week — not a list, not a project, just one thing. It keeps January gentle and stops the overwhelm before the season even begins.

Looking Ahead

January is all about preparation, not pressure. The more calmly you set things up now — seeds chosen, tools cleaned, a loose plan in place — the easier the rest of the year will feel. Spring will be here before you know it, and you’ll be ready.
