In September, you can plant a variety of vegetables suitable for cooler weather and autumn or early spring harvests. Key vegetables to plant in September include:

• Spinach : Sow directly in shallow drills or pots for a late fall or early spring harvest. Cover with fleece from October to protect from frost

• Salad leaves : Sow mustard leaf, winter salad mixes, mizuna, and winter lettuces like 'Winter Density' either outdoors in sheltered spots or under glass

• Broad beans : Plant autumn-hardy varieties such as 'Aquadulce Claudia' to establish over winter and crop earlier in spring

• Peas : Sow hardy winter varieties like 'Douce Provence' or 'Meteor' for overwintering and early spring harvest

• Radishes : Fast-growing and suitable for late sowing to mature before frost

• Turnips : Plant in cool, moist soil for baby turnips ready in about six weeks

• Onions : Plant sets of autumn-hardy varieties such as 'Troy' or 'Radar' for earlier harvest next year

• Garlic : Plant in fall for harvest next spring or summer; choose hardneck or softneck varieties depending on climate

• Other cool-season crops : Carrots, kale, cabbage, broccoli, Swiss chard, beets, collard greens, arugula, and mustard greens can also be planted in September for fall or winter harvests

September is ideal for planting these vegetables because the soil is still warm, air temperatures are cooling, and plants focus on root growth, helping them survive winter and produce early crops in spring

. In summary, September is a great time to plant cool-season vegetables and overwintering crops such as spinach, salad greens, broad beans, peas, radishes, turnips, onions, garlic, and various leafy greens to extend your growing season and secure early harvests
