January can feel like the slowest start to the year. However, for me, it’s the month where all the promise begins. Let me show you what to sow in January in the UK for a great year of growing.
January can feel like the quietest time of year in the garden. However, it’s actually the perfect opportunity to kick-start your growing season. Even in the depths of winter, you can do plenty to get a head start on the new year. You can sow seeds indoors or under cover. You might even sow directly outside for the hardiest crops. This guide will help you make the most of those January days. It will also prepare you for a productive year in your garden.
Why January is an Important Month for Sowing
January might seem too early to start sowing. However, starting now has some great advantages. Starting seeds indoors helps you get a jump on the season, and certain hardy crops thrive with an early sow. Plus, sowing is an excellent method to maintain your gardening enthusiasm. It keeps your spirit alive while you wait for the warmer months.
Benefits of January Sowing
- Early Harvest: By starting in January, you’ll be able to harvest earlier, which can extend your overall growing season.
- Stronger Plants: Sowing early indoors helps create strong plants that can better withstand pests and diseases later in the year.
I remember my first attempt at sowing in January—I had doubts. But seeing those little seedlings break through the soil during the bleak mid-winter was a game-changer. It brought so much optimism to the coldest months.
Can I Plant Anything in January in the UK?
Absolutely! January might be cold. However, there are still plenty of seeds you can plant. This gives you a head start on the growing season. You can plant hardy vegetables that thrive in the cold. Consider early-start flowers as well. January planting involves using indoor growing spaces. Alternatively, provide some protection outdoors. Let’s look at what you can get started on.
If you’re like me, you might find the cold of January a little uninspiring for gardening. But trust me, there’s nothing better than seeing those early seedlings sprout—it’s a promise of warmer days to come.
Vegetables to Sow Indoors in January
Some vegetables need a longer growing season, making January an ideal month to begin sowing indoors. Gardeners World has some great ideas on what to so but here are some great choices to start in a heated greenhouse or on a sunny windowsill:
- Chillies and Peppers: These need a long growing season, so the earlier you sow them, the better. Start seeds in a warm propagator to ensure good germination. Aim for temperatures between 20-25°C. If your home tends to be cooler, use a heated propagator to maintain a consistent temperature.
- Aubergines: Another heat-loving crop, aubergines benefit from early sowing, giving them a head start for a summer harvest. Keep them in a warm spot. Make sure seedlings have enough light. Use a grow light if natural light is limited. (RHS)
- Tomatoes: January sowing is possible for those keen to grow tomatoes. You need plenty of light and warmth to support seedlings. Consider using grow lights to ensure your seedlings don’t get leggy.
One mistake I made in my early gardening days was not giving my seedlings enough light. They ended up spindly and weak. Since then, I’ve invested in a good grow light setup—it’s made all the difference!
Vegetables to Sow Outdoors in January
While it may be cold, some hardy vegetables you can still sow in January in the UK directly outside or under cover:
- Broad Beans: Varieties like ‘Aquadulce Claudia’ are hardy enough to be sown outdoors in January. Sow them under cloches to give them a little extra protection. Cloches help to keep the soil warm and protect against frost damage.
- Onion Sets & Garlic: If the ground isn’t frozen, you can plant onion sets and garlic. They’ll establish roots early and be ready for strong growth when spring arrives. Make sure the soil is well-drained to prevent rot.
Broad beans are one of the oldest cultivated plants and have been a staple in the British Isles for centuries. Their resilience in cold weather makes them perfect for January sowing.
What Seeds Are Best to Plant in January?
If you’re wondering what seeds are ideal to start in January, here are some of the best options:
- Chillies, Peppers, and Aubergines: These vegetables thrive with an early start indoors to make the most of the growing season.
- Broad Beans and Onion Sets: Hardy vegetables like these are perfect for direct sowing outdoors or under cover.
- Sweet Peas: These flowers can be started now for early blooms in spring. Soak the seeds overnight before sowing to improve germination.
Herbs to Sow in January in the UK
If you love cooking with fresh herbs, January is a great time to start growing your own indoors:
- Basil: Though it needs warmth, basil can be sown indoors and kept in a warm, bright spot. Use a heated mat if temperatures drop too low.
- Coriander: Perfect for windowsill growing, coriander grows quickly and will be ready for harvest before you know it. Ensure it gets plenty of sunlight and regular watering.
- Chives: Another good option for January, chives can be started indoors and later transferred outdoors when the weather warms up.
Flower Seeds to Start Indoors
January is also a great time to sow flower seeds that need a long growing period:
- Sweet Peas: These traditional flowers can be sown in January for earlier blooms. Keep them in a cold frame or unheated greenhouse, and use root trainers to give them a strong root system.
- Begonias: If you have a heated propagator, begonias can be started now for a colourful summer display. Light is crucial for these early sown plants, so keep them in a bright spot.
Tips for Successful January Sowing
- Provide Plenty of Light: Seedlings started in January need as much light as possible. A bright windowsill or grow lights can make all the difference. Ensure your seedlings receive 12-14 hours of light per day to keep them strong.
- Heat Matters: Many seeds benefit from bottom heat for germination. A heated propagator can help maintain a stable temperature. Keep temperatures consistent to improve germination rates or use horticultural fleece to protect plants from frost.
- Be Patient: Germination can be slower in January. Don’t be discouraged if your seeds take a little longer to sprout. Remember, conditions like lower light and temperatures can slow plant growth. This is normal for this time of year.
Stay Connected to the Garden
It’s still winter, but sowing seeds in January keeps you in touch with your garden. It helps you beat those winter blues. Watching seedlings emerge can be hugely rewarding. Before you know it, you’ll be nurturing strong young plants ready for spring planting. Consider keeping a gardening journal to track what you’ve sown, the conditions, and the progress of your plants.
I find that keeping a simple journal really helps keep me motivated—especially during the cold months. Write down what you sowed, how it went, and any surprises. Before long, it becomes a treasure trove of experience.
