September planting and harvesting guide

September is when we can begin to welcome autumn into the garden. While this season and month is a little less about planting and a bit more about harvesting, it’s still and all-important time to prune and trim back certain plants and trees to help them survive well over the winter.

It’s possible that September can be mild, but certainly you can expect it to cool down through towards the end of the month. Keep an eye on your more delicate crops to ensure they’re protected from any big drops in temperature, and ensure that you’re feeding regularly as you come close to harvesting.

Below is our straightforward guide to which fruit and veg you can plant in September, as well as which will be ready to harvest if you’re already growing.

For instructions and advice on how to grow fruit and veg in containers and small spaces, read our guide.
