May is a very promising month for the vegetable gardener. The birds are singing, the sun is (usually) shining and the soil is beginning to think about warming up. 

If you're short on propagation space (and who isn't), then May is a brilliant month to begin sowing the bulk of your heirloom vegetable seeds outside - either in pots or directly into the soil. 

Here's my list of what to sow in May, broken down into what to sow undercover, what to sow undercover OR outside and what to sow outside directly into the soil. When I say sow 'undercover' I mean sowing in pots or trays on a windowsill, greenhouse or in a polytunnel.

 

Sow undercover:

Pumpkins, Butternut and Winter Squash

Courgettes

Sweetcorn

French beans

Basil

Greek Basil

Stridolo

Agretti

 

Sow undercover or outside

Lettuce

Leeks

Spring onions

Parsley

Chard

Beetroot

Broccoli

Kale

Cabbage & Brussels Sprouts

Perennial Herbs

 

Sow outside direct into the soil

Carrots

Parsnips

After mid-month:

Swede

Courgettes

Squash

Sweetcorn
