Best veg seeds to plant in December

For the easiest winter crop, try growing cress or sprouting seeds on a windowsill. We’ve got beansprouts, alfalfa, fenugreek, and sprouting broccoli to liven up soups, sandwiches, stir fries and winter salads. Read our helpful guide to growing vegetables from seed for more advice, and see the Frequently Asked Questions below for varieties.

What are the best onion seeds to sow in December?

Onion ‘Globo’ and Onion ‘Aisla Craig’ are both good varieties for cooking and exhibiting. Onion ‘Exhibition’ is a popular variety to start from seed, often sown for the show bench as it can produce bulbs of up to 1kg.

Is it too early to sow chilli seeds indoors in December?

Chilli seeds can be sown in December but, as light levels are low, you would need a grow light as well as a propagator to get the seeds to germinate. It’s often best to wait until January or February.

What veg seeds can be given a head start in winter?

Keep busy in the winter by sowing broad beans, Pea ‘Douce Provence’ and onion seeds. You’ll get slightly earlier crops and extend your harvest season.
