What to Plant in January in the UK

January is one of the quietest months in the UK vegetable garden, but it marks the beginning of a new growing season. While most outdoor planting is still paused due to cold weather and short days, there are a few small steps gardeners can take to get ready for spring.

January is mainly about preparation, planning, and starting a few crops indoors.

Vegetables to plant in January

Outdoor planting is usually limited in January, but in mild conditions you may be able to plant:

  • garlic

  • broad beans (in some areas)

If the ground is frozen or waterlogged, it’s best to wait.

Seeds to start indoors

January is a good time to begin growing a few vegetables indoors if you have a warm, bright space.

You might start:

  • onions from seed

  • early lettuce

  • herbs

Seeds will grow slowly due to limited daylight, but starting early can give plants a head start.

Using greenhouses or cold frames

Protected growing spaces can help extend the season.

If you have a greenhouse or cold frame, you may be able to grow:

  • winter lettuce

  • spinach

  • herbs

Growth will still be slow during winter.

Preparing for spring

January is an excellent time to prepare for the growing season ahead.

You can:

  • plan what to grow

  • order seeds

  • clean tools

  • check compost supplies

  • prepare containers

These small tasks make spring gardening easier.

A quiet start to the gardening year

January may feel slow in the garden, but preparation now helps the growing season begin smoothly.

As daylight gradually increases, planting opportunities will soon follow.

The gardening year really begins to pick up in February and March.
