Seeds to Sow in March

Buckle up! We’re going full throttle on seed sowing this month. March is a month where we can sow a lot, but it’s still quite chilly so protection is paramount.

Indoors

• Tomatoes, peppers, chillies and aubergines. If you didn’t start these in February then now is the time. These need a long growing season.

• Courgettes (late March)

• Pumpkins and squash (late March, under cover)

• Basil and tender herbs

• Cosmos, zinnias and other half-hardy flowers
  

Outdoors using cloches, fleece or tunnels

• Carrots (early varieties)

• Beetroot

• Lettuce, spinach and salad leaves

• Radishes

• Spring onions

• Early peas
  

Direct sowing outdoors in milder areas or well-prepared beds

• Broad beans

• Parsnips

• Onions from seed

• Swiss chard

• Rocket

• Hardy annual flowers (calendula, nigella and cornflowers are some of my favourites)

A Gentle March Reminder

March rewards time spent, not speed.

• Don’t rush everything at once—cold snaps are still possible.

• Succession sow little and often rather than all in one go. Salad leaves are a great one for succession sowing.

• If you want to sow outdoors but the soil sticks to your wellies, it’s still too wet to sow into.
