What to Sow in January in the UK

As the crisp air of January sweeps across the United Kingdom, it brings with it the promise of a new year and the anticipation of a flourishing garden. While the landscape may seem dormant, for gardeners, this month is an opportune time to begin the journey of growth and rejuvenation. In this guide, we’ll explore the diverse array of plants that can be sown in January, setting the foundation for a vibrant and bountiful garden.

Hardy Vegetables – A Robust Start

The cool climate of January is ideal for sowing certain hardy vegetables, which can endure the lower temperatures and give you a head start for the year.

  • Broad Beans: These robust beans are perfect for an early start. Sow them under cover, such as in a cold frame or a greenhouse, to protect them from the harshest winter weather. Planting broad beans now ensures an earlier harvest, often by late spring or early summer, rewarding you with fresh, tender beans that are a delight in various dishes.
  • Onions and Shallots: Starting onions and shallots in January is a smart move for any gardener. Begin by sowing them in trays in a greenhouse or on a bright windowsill. This early start allows the bulbs to develop strength before being transplanted outdoors in spring. Not only does this extend the growing season, but it also leads to larger, more flavourful bulbs.
  • Garlic: If you missed autumn planting, fear not – January is still a suitable time to plant garlic cloves. Garlic planted now will have enough time to establish roots before the spring warmth encourages leaf growth. Choose a sunny spot and well-drained soil to ensure the best growth.

Leafy Greens – Embrace the Chill

Leafy greens are not only nutritious but also remarkably resilient, making them excellent candidates for early sowing.

  • Lettuce: Opt for varieties that are tolerant of lower temperatures. Sowing lettuce seeds in a greenhouse or under a cold frame can yield an early crop of fresh, crisp leaves. This is especially rewarding for salad lovers, as homegrown lettuce is unmatched in flavor and texture.
  • Spinach: This fast-growing leafy green is perfect for a January start. Spinach can germinate in cool temperatures and mature quickly, providing you with a bountiful crop of tender leaves that are perfect for salads, sautés, and smoothies.
  • Kale: This superfood thrives in cooler weather. Sowing kale in January means you’ll get an early crop of its nutrient-rich leaves. Kale is versatile in the kitchen, ideal for everything from hearty stews to crispy baked snacks.

Blooming Beauties – Flowers to Start Indoors

Flowers sown in January can bring an early burst of colour and life to your garden.

  • Sweet Peas: These fragrant beauties are a favourite among gardeners. Sow sweet pea seeds in pots indoors and nurture them until they are ready to be moved outside. Their delightful fragrance and vibrant colours will be a highlight in your garden come spring.
  • Pansies: Pansies are hardy flowers with charming faces. Starting them in a greenhouse in January prepares them for an early spring display. They’re perfect for adding splashes of colour to your garden or in containers.
  • Dahlias: For a more dramatic display, start dahlias indoors in pots. These bold and beautiful flowers require a frost-free start, so keeping them indoors until the risk of frost has passed is essential. Dahlias are known for their stunning blooms and will be a showstopper in any summer garden.

Herbs for the Hearth

There’s nothing quite like the convenience of fresh herbs grown right in your kitchen. In January, start sowing herbs like parsley, basil, and chives on a sunny windowsill. They not only add freshness to your cooking but also bring greenery and life to your indoor spaces.

Soil and Bed Preparation

While you sow seeds indoors, don’t forget to prepare your outdoor garden beds. Clearing away debris, adding compost or well-rotted manure, and planning out where each plant will go are crucial steps in ensuring a successful gardening season.

Safeguarding Early Plantings

Protecting your early plantings is key. Use cloches, cold frames, or even a greenhouse to shield young plants from frost and cold winds. This extra care can make a significant difference in the survival and growth of your plants.


January may be the coldest month of the year, but in the gardening world, it is a time of potential and preparation. By choosing the right plants to sow and taking steps to protect them, you can set the stage for a year of gardening success. With patience and care, the seeds you sow now will transform into a
