There's lots to harvest in the vegetable patch, including spinach, peas, beets, carrots, salads, potatoes and globe artichokes; shallots and spring-planted garlic may be ready as well.

Pick courgettes before they become marrows.

Over Wintered onions can be lifted and used.


Fruit picking can begin in earnest, with strawberries, cherries, summer-fruiting raspberries, currants and the earliest of the plums. Remember to harvest red, and white, currants in bunches, still on the stalk - they will keep and taste better. Blackcurrants can be picked singly or in clusters, as preferred.

Sideshoots that form on pinched-out grape laterals can be stopped at one leaf. Leaves that are shading grape bunches can be removed, to speed ripening of the clusters. 

Later in the month summer pruning of restricted fruits (e.g. cordons, espaliers, fans) can begin. Cherries and plums can be summer pruned after cropping.

Thin apples after the June drop if still overcrowded. Remove blemished and central fruits from the clusters first. Branches still heavily laden after thinning can be supported with a V-shaped stake.

When summer-fruiting raspberries have finished cropping promptly cut out the old canes.

Continue to peg down strawberry runners if new plants are needed.

Continue to tie in and train new blackberry canes.

Propagate blackberries and other cane fruits with long, lax stems by tip layering.

Cut back sideshoots on gooseberries to four or five leaves, or just beyond the fruit clusters. This will speed ripening, encourage fruit bud formation for next year, and control aphids on the new growth. Red and white currants may be pruned in the same way.


Herbs can be harvested to keep the young shoots coming throughout the summer.

Excess pickings can be dried for use throughout the year.

Around the Garden

Continue to hoe off weeds in dry weather. 

Carrots can still be sown, but beware carrot fly when thinning existing seedlings

Plant out leeks and brassicas for a winter supply, if not yet done.

Summer cauliflowers may need shading to prevent the curds scorching in bright sun.

Stop cordon tomatoes by removing the main shoot. Look for the leaf that's above the fourth truss and cut it off. This should ensure that all the fruits ripen by the end of the season. Bush tomatoes can be left to their own devices.

Climbing beans may also need stopping, to maximise cropping on existing sideshoots. Stop them when they reach the tops of their supports. Beans need sufficient watering to help the seed pods set.

Remember to pick your bean and pea pods as they mature, to stop them becoming tough and stringy later in the summer.

Any non self-blanching celery cultivars will need earthing up.

Watch out for early leaf rots caused by potato blight and tomato blight.

Stunted potato plants should be lifted to check the roots for the tiny nodules of potato cyst eelworm.

Keep an early eye out for the sunken brown patches of blossom end rot on tomatoes, especially if the weather has been dry. It can be a sign of irregular watering. Pale, haloed ‘ghost spots’ can be avoided by not splashing the fruits when watering tomatoes.
