As autumn progresses, focus on preparing the garden for winter. Clear spent crops and weeds, and consider adding compost or well-rotted manure to enrich the soil. Protect newly sown cold-tolerant crops with cloches or row covers if early frosts are anticipated. Ensure good drainage, especially for overwintering crops like garlic and broad beans, to prevent rot from increased rainfall. Begin tidying up garden beds and cleaning tools.
