Full list of vegetables to sow in September for a plentiful spring harvest
Gardeners are being urged to sow a variety of different vegetable and flower seeds this month to be ready for next spring.
A recent guide from gardening enthusiast 'allotmentality' is providing home growers with valuable insights into extending their harvest well beyond the traditional growing season. Uploaded on September 6, 2025, the video details a comprehensive plan for sowing vegetables and flowers in September, aiming for continuous produce through winter and into early spring. The guide highlights specific winter-hardy varieties such as 'Winter Giant Spinach,' 'Jack Ice' and 'Winter Marvel' lettuce, and various oriental greens like Claytonia, Mizuna, and Wa Wa Ga Choi stem mustard. "Now that the temperatures have cooled, it's a great time to sow spinach without the plant bolting," the gardener explains, emphasizing the benefits of late-season planting. She also demonstrates the process of sowing kale and turnips, which can be harvested as baby roots later in the year. Beyond vegetables, the video encourages planting flowers like Calendula, Breadseed poppies, and Viper's Bugloss, noting their usefulness around the vegetable patch. "Viper's Bugloss is my favourite, which the bees love, and it makes a lovely cut flower," she states, highlighting the ecological benefits. For those feeling adventurous, the guide also mentions planting saffron crocuses, albeit with a note on timing. The gardener, based in Hampshire, UK, advises holding off on broad beans and winter-hardy peas for a couple of weeks due to warmer early September temperatures in her region, ensuring optimal conditions for overwintering.
