July in the Garden
July is high summer in the UK, with long, bright days and gardens growing at full pace. Warm spells can quickly dry containers, hanging baskets and thirsty vegetable beds, while heavy showers may encourage lush growth and fungal troubles. Harvests gather momentum: courgettes, beans, early potatoes, salad leaves and soft fruit should be coming steadily. Keep paths open, pick regularly and enjoy the busiest, most colourful part of the gardening year.
What to sow & plant in July
Sow little and often for continuity: lettuce, rocket, radish, spring onions, beetroot and coriander can all fill gaps. Start autumn and winter crops, including kale, winter salads, spinach and oriental leaves, in module trays or a sheltered seedbed. Sow spring cabbage now for planting out later in summer. Plant out leeks, brassicas and late courgettes only if they can be watered well. Under cover, sow basil and parsley for fresh late-season plants, and prick out young seedlings before they become crowded.
Garden jobs for July
Water deeply in the cool of morning or evening, aiming at the soil rather than foliage, and mulch beds to conserve moisture. Feed tomatoes, cucumbers, peppers and courgettes regularly, following the fertiliser label. Tie in cordon tomatoes, remove side shoots and improve airflow around plants. Harvest beans, courgettes and soft fruit frequently to keep crops coming. Lift early potatoes as needed, net fruit from birds and summer-prune trained apples and pears. Check tomatoes and potatoes for blight, removing affected leaves promptly and keeping foliage dry where possible.
Northern England & Scotland
In cooler northern England and Scotland, summer warmth may arrive later and evenings can feel distinctly cool. Keep fleece or cloches available for tender crops, especially sweetcorn, squash and outdoor tomatoes. Sowings for autumn use may need a protected spot or greenhouse to make worthwhile growth. Pick crops promptly during wet spells, as slugs and fungal problems can build quickly.
Southern England
In the milder south of England, crops often ripen earlier and watering can become the main concern during dry weather. Continue succession sowing outdoors in a lightly shaded bed, and plant a final batch of French beans or courgettes where space allows. Greenhouses may need daily ventilation and shading. Watch ripe fruit closely, as it can pass its best quickly in warm conditions.
