Gardeners with vegetable patch urged to do one simple thing for abundant crop

Some key steps – and a trip to the garden centre – now, will mean enjoying homegrown produce including courgettes, pumpkins and carrots later on in the season, says top gardener

The growing season is well under way, frost is just a memory now and vegetable patches are starting to show signs of growth. So now is the time to plant out young courgettes, pumpkins, and squashes. If you didn’t grow these from seed, there are plenty available in garden centres.

Meanwhile, thin out carrot seedlings – remove these thinned seedlings because if they are left about their scent will attract carrot fly. You can cover with horticultural mesh to keep this away.

Collect seed from candelabra primulas and sow fresh. Pop a few nasturtium seeds in pots for a late summer vibrant display. Start feeding tomatoes in grow bags with high potash feed to encourage flowers and fruit formation. Fruit will also need your attention – put netting over soft fruit such as gooseberries before the birds tuck in.

Here are my other jobs to do in the garden this week:

Borders are filling up with colour. Oriental poppies have begun to bloom in the front garden, bringing with them a riot of colour and drama. Their flamboyant, bright orange-red petals are striking, each flower marked with a dark, almost black blotch at the base, encircling a regal-looking purple centre.

Though their display is brief, typically lasting around ten days, their perennial nature makes them a reliable and rewarding addition to a mixed border, returning year after year. These poppies grow on stout, hairy stems that can sometimes flop under the weight of their impressive blooms.

A little forward planning can help here — staking the stems early in the season provides much-needed support to keep the flowers upright and looking their best. There’s also a wide array of stunning cultivars to explore. ‘Royal Wedding’, for instance, produces silky white petals with a dramatic purple blotch at the base, while the beloved ‘Patty’s Plum’ is admired for its maroon, ruffled flowers

After flowering, oriental poppies can be cut back to tidy up the plant, though many gardeners choose to leave the ornamental seedheads in place for their sculptural beauty. While these cultivars don’t grow true from seed, they can be propagated through root cuttings — a task best tackled in autumn.

Simply dig up the plant, snip healthy roots into 4cm lengths, and plant them in cuttings compost. The parent plant can then be returned to the soil to re-establish itself.

Among annual poppies, the corn poppy, Papaver rhoeas, is perhaps the most iconic. Also known as the field or Flanders poppy, it has become a powerful symbol of remembrance for those lost in war. Its seeds are remarkably resilient, capable of lying dormant for decades until disturbed.

During the First World War, the upheaval of soil on battlefields in France and Belgium caused these poppies to bloom en masse, creating vivid displays that inspired Lieutenant Colonel John McCrae’s famous poem: In Flanders fields the poppies blow, between the crosses, row on row…

Another notable species is Papaver somniferum, the opium poppy. Historically associated with the Opium Wars between Britain and China in the 19th century, this species is still cultivated today for medicinal purposes as the natural source of morphine and codeine.

In the garden, however, it’s prized more for its striking ornamental forms. These hardy annuals are best sown directly into the ground in spring or autumn, as they dislike being transplanted.

Varieties such as ‘Black Swan’, with its finely cut, deeply coloured petals, or the heirloom ‘Hungarian Blue’, known for its simple, silky purple blooms, make bold, beautiful statements.

For gardeners with acidic soil and cooler, damp climates, the elusive Himalayan blue poppy, Meconopsis betonicifolia, might be worth a try. Native to the mountainous regions of Nepal, Tibet, and Myanmar, this rare, short-lived perennial is often considered the “holy grail” of blue flowers.

Though notoriously tricky to grow, it thrives in the cooler, wetter conditions of northern England and Scotland. However, even a brief spell of strong sun in dry weather can quickly damage these delicate, captivating blooms.

With their dazzling beauty, fascinating histories, and evocative symbolism, poppies continue to enchant gardeners, poets, and nature lovers alike.
