There’s a whole range of veg to sow in September (and right up until October in fact), and now’s the time when your cold frame and greenhouse come into their own. If you want to sow your September seeds outside, use a fleece of perforated polythene to protect them.

Transplant spring cabbage into their final growing positions. For a supply of herbs during the winter, pot up basil, marjoram, mint, oregano and parsley plants and grow them on the kitchen windowsill. You can also pot up cut-and-come again salad varieties pots for tasty leaves in the autumn. 

Crops should be picked regularly ensuring they are always fresh and tender, and items such as courgettes and beans shouldn’t be left too long prior to picking.

It’s also time to grow autumn-planting shallots and onions, and you will be able harvest June to July (Shallots until September) the following year.
