As the days get longer (hurrah, it's not dark by 4pm anymore) and the soil starts to warm up, it's the perfect time to get out into the garden and give your plants a strong start.

From fruit to herbs and veg, there's a whole host of seeds to sow now that'll leave you with beautiful blooms and tasty crops in the months to come.

Just make sure the ground is workable – not frozen or waterlogged – grab your gloves, trowel, rake and labels, then get ready to grow.

So, alongside your other March gardening jobs, here's what to plant before we bid farewell to the month:

Dahlia tubers

Delightful dahlias are one of the most diverse blooms: coming in a riot of rainbow colours, shapes and sizes. Julian Palphramand, head of plants at British Garden Centres, advises: "Now is the perfect time to start dahlia tubers off outdoors, potting them up in barely moist compost somewhere bright and frost-free. They'll begin to shoot in the coming weeks, giving you sturdy young plants ready to go out after the last frost in mid-May."

What to Read Next

The reward for this small act of planning is great, blowsy blooms from July right through to the first frosts of autumn. 'Cafe au Lait' remains a firm favourite, but wide, inky varieties like 'Karma Choc' are equally irresistible.

Broad beans

Delicious stirred into creamy risottos, fresh salad leaves or lemony pasta dishes, the culinary uses are endless with broad beans. But before we can take them into the kitchen, we've got to get growing.

Julian says: "Hardy, unfussy, and one of the most rewarding crops you can grow from seed, broad beans can be sown directly into the ground now and will shrug off a late frost without complaint. By early summer, you'll be rewarded with armfuls of plump pods and fresh beans. Try 'Aquadulce Claudia' for reliability, or 'The Sutton' if space is tight."

Shallots

This miniature member of the allium family is highly prized for its delicate, sweet, slightly piquant flavour.

"These need to be ground before April," Julian advises. "Push sets into soil with just the tips showing, in rows around 25cm apart, and let the season do its work. By July, you'll be lifting clusters of golden bulbs to dry on slatted shelves in the shed.

"'Jermor' is a long, elegant French variety; 'Red Sun' adds a welcome splash of colour to both bed and kitchen."

Sweet peas

One of the nation's favourite flowers, sweet peas are beloved for their fragrance and cutting and climbing potential.

To introduce them to your garden, Julian suggests: "Sow into deep modules in a cold frame, pinch out the growing tips at around 10cm, and you'll have strong, fragrant plants ready to climb come late April. The old-fashioned Spencer varieties have a scent that is simply incomparable and also make great cut flowers."

Hardy annuals

Some of the easiest flowers to grow, hardy annuals self seed so come back year after year, making them a great budget-friendly option, too.

"Cornflowers, nigella and calendula need to go into a prepared bed now, and they'll establish strong roots before the spring rush," says Julian, "Hardy annuals actually prefer cooler conditions, and an early sowing will always outperform one made in summer."
