Vegetables to Sow in March

March is an exciting month for vegetable growers, as many crops can be sown indoors or directly outdoors, depending on the weather.

Sow Indoors:

Tomatoes, Peppers, and Aubergines – These warmth-loving plants need an early start. Sow seeds in trays or small pots and keep them in a warm, sunny windowsill or heated propagator. For more tips on starting tomatoes indoors visit Gardeners World's 'How To' page.

Cucumbers and Courgettes – Start these in pots indoors so they’re ready to be transplanted outside after the last frost.

Lettuce and Salad Leaves – Perfect for continuous harvesting, these can be grown in trays inside or in a greenhouse.

Brassicas (Cabbage, Cauliflower, and Brussels Sprouts) – Sow in seed trays indoors so they’re ready for transplanting later in spring.

Sow Outdoors:

Carrots and Parsnips – These root vegetables prefer to be sown directly into well-drained soil. Protect young seedlings from frost using Hortiwool Garden Pads as an insulating mulch.

Broad Beans and Peas – Hardy crops that can be sown directly in the soil. Use Hortiwool Garden Pads around emerging plants to help retain moisture and suppress weeds.

Spinach and Chard – Perfect for growing in March! These leafy greens tolerate cooler temperatures and can be sown in early spring.

Onions and Shallots – Start sets directly into the ground or in pots for transplanting later.

Fruit to Plant in March

Strawberries – Plant bare-root or potted plants in well-prepared soil. Mulching around plants with Hortiwool Garden Pads helps retain warmth and moisture, promoting strong root growth.

Raspberry and Blackberry Canes – These can be planted directly into the ground while still dormant.

Gooseberries and Currants – Establish these fruit bushes early for a summer harvest.

Rhubarb – If not already in the ground, plant rhubarb crowns now for a delicious harvest later in the year.

Flowers to Sow or Plant in March

March is a great time to introduce color to your garden by sowing flowers that will bloom later in the season.

Sow Indoors:

Sweet Peas – Start these in deep pots to develop strong roots before planting out.

Marigolds, Petunias, and Geraniums – Early sowing ensures vibrant summer displays.

Lupins and Delphiniums – Perennials that benefit from an early start indoors.

Sow or Plant Outdoors:

Pansies and Violas – Hardy flowers that add spring color.

Hardy Annuals like Cornflowers and Nigella – These can be sown directly into the soil.

Bulbs such as Lilies and Gladioli – Plant now for a stunning summer display.
