🥬 10 Winter Crops to Plant Before the End of Summer

ByAllotment Kitchen

As summer reaches its peak, it’s tempting to sit back and enjoy the fruits of your labour. But if you want fresh, homegrown produce through autumn and winter, now is the time to sow. From leafy greens to hardy roots, these ten winter crops can be planted in late July and August — giving you months of harvest even as temperatures drop.

Whether you’re working with raised beds, containers, or a full allotment plot, this guide will help you make the most of your growing space year-round.

🧤 Why Plant Now for Winter?

Planting winter crops before the end of summer gives them time to establish while the soil is still warm and the days are long. Many of these varieties are frost-hardy, thrive in cooler weather, and will continue to grow slowly or hold in the soil through winter.

👉 Tip: Clear out finished crops like garlic, onions, and early peas to make space for your winter garden.
