What to sow indoors, what to sow direct, and what to plant out each month.
A Growing Adventure Starts Here
A seed is a fascinating thing. Inside that tiny, dry shell is everything required to become a sunflower taller than your head, a tomato bursting with summer flavour, or a handful of fresh herbs for your dinner.
At Bees Seeds, we believe growing should be a joy, not a chore. Whether you have a sprawling back garden, a small balcony, or just a sunny windowsill, this calendar is for you.
Use this guide as a year-round companion. Think of it as a friendly nudge to get your seeds in the soil. Follow along, celebrate every green shoot, and remember that even the most seasoned gardener started exactly where you are now.
A quick note on timing: The UK is a large place. The south of England warms up several weeks earlier than Scotland or the north of England. Use this calendar as a general guide, but always keep an eye on your local forecast, particularly around the last frost dates in spring.
A note on succession sowing: Many seeds — particularly salad leaves, annual herbs, carrots, radishes and spring onions — appear across several months. This is intentional. Sowing a small amount every two to three weeks ensures a constant harvest rather than a glut followed by nothing.
The Monthly Sowing Calendar
January: The Quiet Before the Green
January often feels like the garden is sleeping. However, it is the perfect time for ambitious gardeners to get a head start indoors.
- What to sow indoors: Chilli peppers, aubergines, onions in modules, hardy salad leaves and oriental greens.
- What to sow direct: Nothing. The soil is too cold and wet.
- What to plant out: Nothing. Focus on planning and ordering seeds.
Bees Seeds Tip: If you do not have a heated propagator, January is a great time to organise your seed trays, compost and pots.
February: The First Stirrings
The days are getting longer, and the garden is waking up. You can start a good range of crops indoors.
- What to sow indoors: Tomatoes, peppers, chilli peppers, aubergines, broad beans, round-seeded peas, onions and salad leaves.
- What to sow direct: In the mildest parts of the south, broad beans may be sown under a cloche.
- What to plant out: Nothing. Protect all seedlings from frost.
Bees Seeds Tip: Tomatoes sown in late February will be strong, well-established plants by May. Avoid sowing too early if you lack good light.
March: The Season Begins
March is a turning point. The soil starts to warm, the light is returning, and the gardening year begins in earnest.

- What to sow direct: Winter salads, oriental greens, rocket, spinach, spring onions, broad beans, hardy round-seeded peas, garlic, coriander and parsley under cover.

Every Seed Is a Small Act of Hope
Gardeners are optimistic people. Every seed you sow is an investment in a future where that tiny thing becomes something beautiful or delicious.
You do not need to be an expert or have a perfect garden. You just need a seed, some compost, water and the willingness to watch and wait.
When that first green shoot appears, you will understand why people do this year after year. It is about the whole journey — the planning, the sowing, the nurturing and the harvest.
We are with you every step of the way.
Happy growing,
