Vegetable Seeds to Sow in September: Extend Your Growing Season

September is a fantastic month for gardeners looking to extend their growing season and prepare for a bountiful autumn and winter. As summer draws to a close, the cooler temperatures and shorter days provide ideal conditions for a range of vegetable seeds. With a little planning, you can enjoy fresh, homegrown produce well into the colder months.

During September, temperatures typically range between 10°C and 18°C (50°F to 64°F), which is perfect for sowing hardy greens, root vegetables, and fast-growing crops. It’s also a great time to plant overwintering varieties that will reward you with an early spring harvest. Adding mulch or well-rotted compost to your soil can boost its nutrients and help retain warmth as the season changes.

Whether you’re sowing directly into the ground or using containers, September is a productive time to keep your garden thriving. This guide will explore the best vegetable seeds to sow this month, along with practical tips for successful planting. Make the most of September’s opportunities and enjoy the satisfaction of a garden that continues to provide fresh produce throughout the year.

Corn Salad

Sowing corn salad, or lamb’s lettuce, in September ensures a fresh supply of greens through autumn and early winter. This hardy, low-maintenance plant thrives in cool weather, making it ideal for extending your growing season. Choose a sheltered area with rich, well-drained soil, and sow seeds 1 cm deep in rows spaced about 10 cm apart. Keep the soil consistently moist with regular watering. Corn salad’s mild, nutty flavour makes it a versatile addition to salads and sandwiches. Its resilience means that you can enjoy fresh, home-grown produce even as temperatures drop, adding both nutritional value and a touch of green to your autumn table.

Lettuce – Winter

Plant winter lettuce in September to enjoy fresh greens throughout the colder months. Choose a sunny, sheltered site with fertile, well-drained soil. Sow seeds thinly in rows about 20 cm apart to allow for ample growth space. Keep the soil evenly moist with regular watering, especially during dry spells. Winter lettuce varieties are bred for hardiness, capable of withstanding light frost and offering crisp, delicious leaves all winter long. Whether in salads, wraps, or as a garnish, these greens add a fresh, nutritious touch to your meals, ensuring the delight of garden-fresh flavours well into the chilly season.

Radish

Sowing radish seeds in September provides a quick, rewarding crop for autumn. Opt for a sunny spot with well-drained soil, and sow seeds thinly in rows about 10 cm apart. Regular watering helps maintain soil moisture, essential for fast growth and tender roots. Radishes typically mature in just four to six weeks, offering crisp, peppery bites perfect for salads, garnishes, or snacks. By planting in succession every few weeks, you can extend your harvest period. Radishes are an easy and satisfying choice for gardeners seeking fresh, nutritious additions to their autumn culinary repertoire.
