Seasonal Planting Guide for UK Farmers and Gardeners

Timing is everything in farming and gardening. Planting at the right time ensures your crops have the best conditions to thrive and mature before autumn frosts arrive. Here's a practical guide to seasonal planting across the UK.

Spring (March to May) is the busiest planting season. In March, sow hardy crops outdoors like broad beans, onions, and peas. April is ideal for tender crops once frost risk passes – plant potatoes, courgettes, and squash. By May, the soil is warm enough for beans, sweetcorn, and tender herbs like basil and coriander.

Summer (June to August) is mainly maintenance time, though you can make succession plantings of lettuce and beans every two weeks for continuous harvests. Late July and August are perfect for sowing autumn crops like kale, cabbage, and broccoli that will mature in autumn.

Autumn (September to November) sees you planting garlic (October is ideal) and overwintering onions. Leafy greens like spinach and chard sown in September often produce through mild winters. This is also when you prepare beds with compost for spring.

Winter (December to February) seems quiet, but it's valuable planning time. Check stored produce, maintain tools, and order seeds. In milder southern regions, you can sow broad beans and early peas in February for spring harvests.

Consider your UK region's specific frost dates. Southern England enjoys a longer growing season than Scotland or northern regions, so adjust planting times accordingly. A good rule of thumb: wait until after your area's last frost date before planting tender crops.

Succession planting extends your harvest. Rather than planting all lettuce at once, sow small amounts every two weeks from spring through summer. This gives you continuous fresh crops instead of one glut followed by nothing.

Keep a planting calendar specific to your garden. Note when you planted things, when they germinated, when they were ready to harvest, and any problems encountered. This becomes your personal growing guide, more valuable than any generic advice because it reflects your exact location and conditions.

Start with a simple calendar marking key dates: last frost, first frost, and ideal planting windows for your favourite crops. As you gain experience, you'll develop an intuitive sense of timing that makes planning effortless.
