Jobs to Do in the Garden This Month

Start With the Soil and the Weeds

Before you reach for the seed packets, spend twenty minutes walking the plot with a cup of tea in hand. British weather changes its mind quickly, and the jobs that matter most this month depend on whether you have had a fortnight of warm drizzle or a dry, breezy spell. Push a fork into the top few centimetres of soil. If it crumbles, you can work it. If it clags together and sticks to your boots, leave it alone and get on with something else.

Weeding now saves you weeks later. Annual weeds are easiest to kill while they are still small enough to be hoed off at the root on a dry, sunny morning. Perennials are a different matter: dig out every last scrap of couch grass, bindweed and ground elder root, or you will be pulling them out of your carrots for years. On a no-dig bed, simply lay cardboard and a generous mulch of well-rotted compost over the worst patches and plant through it.

It is also the perfect moment to top up beds with compost or homemade leafmould, and to check that your water butts are clean, connected and not leaking at the downpipe. A full butt in spring is worth its weight in gold in July.

Sowing: Little and Often

The single best habit for a small plot is to sow small quantities regularly rather than a whole packet in one go. A row of salad leaves sown every fortnight gives you cut-and-come-again leaves from May to October; one big sowing gives you a fortnight of glut followed by nothing.

What you sow depends on the month, but the principles hold:

• Hardy crops such as broad beans, peas, spinach, chard, parsnips and early carrots can go direct into prepared ground from early spring.
• Tender crops — courgettes, runner beans, sweetcorn, French beans and squash — should wait until the soil has warmed and the last frost has passed. In most of the UK that means late May or early June, later in the north.
• Salad and herbs are worth sowing in modules so you can transplant thinnings into gaps rather than wasting seed.
• Brassicas — cabbages, kale, sprouts and purple sprouting broccoli — are best started in a seedbed or modules and moved on once they are sturdy.

Sow thinly, label everything (you will forget which variety is which), and water the drill before sowing rather than after, so the seed is not washed into a heap. Once seedlings are up, thin them in stages: crowded seedlings compete for water and never reach a decent size.

Greenhouse and Windowsill Jobs

A greenhouse earns its keep this month. Ventilation is the first job of the day — open the door and vents early, or you will cook your tomatoes by mid-morning and invite botrytis with the damp, still air that follows. On cold nights, close everything down again and throw fleece over anything tender.

Prick out seedlings as soon as their first true leaves appear, moving them into individual modules or small pots. Tomatoes, peppers, aubergines and cucumbers all want warmth, good light and steady moisture. Turn them regularly so they do not lean towards the glass, and start feeding tomatoes once the first truss has set.

Harden off anything destined for the plot. A week on a sheltered bench, then a few days outside during the day, then a night or two under fleece, will save you from losing plants to a late frost. It is a slow business, but far quicker than resowing.

Allotment Priorities

Allotments have their own rhythm, and there is usually a committee eyeing up neglected plots. Keep the edges strimmed, the paths mown, and the compost heap turned. If you cannot keep on top of a bed, sow it with green manure — field beans, phacelia or mustard — rather than leaving bare soil for weeds to colonise.

This is also the time to earth up potatoes, stake your peas and beans, and net brassicas against pigeons. Put up supports before plants need them; wrestling canes into a collapsing row of runner beans in July is nobody's idea of fun. If you grow fruit, thin apples and pears where clusters are tight, and tie in new raspberry canes.

Watering, Feeding and Weather Watching

Water deeply and less often, aiming at the roots rather than the leaves, and do it in the evening or early morning to cut evaporation. Newly planted seedlings, courgettes, tomatoes and anything in a container need the most attention. A layer of mulch will halve your watering within a fortnight.

Feed hungry crops — tomatoes, courgettes, beans and leafy greens — with a liquid feed every week or two once they are growing strongly. Keep an eye on the forecast: a warm, humid spell brings blight warnings for outdoor tomatoes and potatoes, while a cold snap means fleece over tender seedlings. Slug patrol after rain, and check under leaves for aphids and cabbage white eggs.

Harvest and Glut Management

Pick little and often, and pick before you think things are ready — courgettes, beans, cucumbers, peas and salad all lose quality fast once they pass their best. Regular picking also keeps plants cropping for longer. Cut herbs in the morning for the strongest flavour and freeze what you cannot use.

When a glut arrives, deal with it the same day: blanch and freeze beans and peas, turn tomatoes into sauce, make chutney from the windfalls, and share the rest with neighbours. That, more than anything, is the quiet pleasure of a British vegetable plot — a bit of planning earlier in the month, and a kitchen full of produce later on.
