Seeds to Sow in September – resources list

What to sow in September. For many gardeners September marks the start of autumn. Food crops are harvested and also the garden starts to shut down for the winter. Growing beds are cleared and put to rest for the next few months. However, there are plenty of seeds that can be sown in September. Because this gives the opportunity for a continued supply of fresh vegetables through the coming months and early next year.

Below is an at-a-glance guide with links of where the seeds can be purchased (updated in August 2021). I have listed seed sources for USA and UK. At Byther Farm we grow most of the fruit and vegetables we need to feed our small family each year.

Until our recent relocation to Carmarthenshire I also ran a small veg box scheme. I plan to start a new market garden in 2022 and offer veg boxes again as a CSA (Community Supported Agriculture) project.

Together with these monthly articles, I also publish a video guide of what to sow in that particular month. If you haven’t already subscribed to my YouTube channel, you can do so here. I publish a new video weekly offering hints, tips and ideas for gardening and preserving food.

For a full list of all the productive plants, fruit, vegetables and herbs that we grew in Monmouthshire , see our what we grow page.
