What to Plant in December in the UK

December is a quiet month in the UK vegetable garden. Cold weather, short days, and frosty conditions mean most planting stops until early spring.

While there is very little to sow outdoors, December is still a useful time for garden maintenance and planning next year’s crops.

Vegetable gardening naturally slows down during winter.

Vegetables to plant in December

In most parts of the UK, there is very little planting to do in December.

In mild areas, you may still be able to plant:

  • garlic

  • overwintering onions

If the soil is frozen or waterlogged, planting should wait until conditions improve.

Growing under protection

Some vegetables can continue growing under protection.

If you have:

  • a greenhouse

  • a cold frame

  • cloches

You may be able to grow:

  • winter lettuce

  • spinach

  • herbs

Growth will be slow due to limited daylight.

Winter garden jobs

December is a good time to focus on simple maintenance tasks.

You can:

  • check stored vegetables

  • clean and organise tools

  • protect containers from frost

  • add compost to empty beds

  • review notes from the growing season

These small tasks prepare the garden for spring.

Planning next year’s garden

December is an ideal time to plan the next growing season.

You might:

  • choose vegetables to grow

  • plan garden layout

  • order seeds

  • review planting calendars

Planning ahead makes spring gardening easier.

A winter pause in the garden

December is a resting period for most vegetable gardens in the UK.

Although planting is limited, preparation and planning help ensure a strong start when the growing season returns.

Gardening becomes active again as winter ends.
