July feels like the height of summer, and in the vegetable garden it quietly becomes two jobs at once. The spring garden is peaking – beans climbing, courgettes swelling, the first tomatoes colouring up – while the smart planting work has already moved on to autumn and winter. Knowing what to plant in July is less about starting the summer garden and more about keeping it alive through the heat and sowing the crops you will actually harvest from October to March.

This guide covers what still goes in the ground in July across European climate zones, why the autumn and winter garden is now the main planting event, and the maintenance jobs that decide whether your beds cruise through a heat wave or stall in it.

A Quick Climate Check for July

Climate shapes July more sharply than any other month, because heat is now the limiting factor rather than cold. Atlantic Cfb gardens (UK, Ireland, Netherlands, northern France) stay mild and moist – this is the easiest zone for July sowings, with soil warm and rarely baking. Continental Dfb zones (Germany, Czechia, Poland, Slovakia, eastern France) hit their hottest, driest stretch, with 28–32 °C days that stress seedlings and push lettuce and spinach straight to seed. Mediterranean Csa zones (southern Spain, southern Italy, southern France) are in full heat management: most summer sowing pauses until the August–September window, and shade cloth plus irrigation decide everything.

If you are not sure where your garden sits, our European climate zones guide explains how to find your zone and what it means for sowing windows.

What Still Goes in the Ground in July

July is the last practical window for several fast summer crops and the opening window for the autumn garden. Sow into moist soil, ideally in the cooler part of the day, and keep the surface damp until germination.

Crop	Sow / plant	Zone notes
French beans (bush)	Direct sow	Cfb and Dfb: last main sowing for an early-autumn crop.
Beetroot	Direct sow	Bolt-resistant varieties for autumn storage roots.
Carrots	Direct sow	Sow by mid-July for autumn roots; fleece against carrot fly.
Swiss chard and leaf beet	Direct sow	Reliable into autumn; very heat-tolerant.
Kohlrabi	Direct sow or module	Fast autumn crop; keep well watered.
Florence fennel	Module or direct	Bolt-resistant varieties for clean autumn bulbs.
Lettuce (heat-tolerant)	Module in shade	Sow in the coolest spot; transplant when cooler.
Pak choi and oriental greens	Direct sow late July	Less prone to bolting once the longest days pass.
Spring onions	Direct sow	Continuous succession through summer.
Turnips	Direct sow	Quick autumn crop from a mid-July sowing.
Autumn radishes and mooli	Direct sow late July	Larger winter radishes for storage.

The Autumn and Winter Garden Takes Centre Stage

This is the single biggest shift in July, and the one most gardeners miss. The beds that will feed you in November and through winter are planted now, while everything else is busy fruiting.

Transplant the brassicas you started in June. Purple sprouting broccoli, winter cauliflower, savoy cabbage, kale, and Brussels sprouts move from modules into their final beds in July. Firm them in well and net against cabbage white butterflies from day one.
Sow leeks' final batch and start transplanting. Leeks sown in spring go out now; drop them into deep dibber holes and puddle in. Harvests run October through March.
Start chicory, radicchio, and endive. These autumn and winter salads are sown in July for heads that stand through the cold.
Sow autumn brassicas direct where you have space. Turnips, kohlrabi, and quick cabbages can go straight in for an October crop.
Plan for overwintering. In milder Cfb zones, late-July sowings of hardy spring cabbage and overwintering onions set up next year's earliest harvests.

Net brassicas before you leave the bed

Cabbage white butterflies find young brassicas within hours in July. Put fine netting over the bed the same day you transplant – one afternoon of caterpillars can strip a row of kale to the stems.

Keep Succession Sowings Rolling

Peak summer is exactly when the salad and herb supply goes silent if you stop sowing. Small, frequent sowings in the coolest, most-shaded patch keep the kitchen supplied.

Lettuce and salad leaves – sow tiny amounts every 7–10 days, always in shade, always heat-tolerant varieties (oak-leaf, batavia, Salanova). For rhythm, see our succession planting guide.
Rocket, coriander, and dill – these bolt fastest in heat, so sow little and often and expect a shorter cutting window.
Spring onions and radishes – quick fillers for any gap that opens as summer crops finish.
Bush beans – a final July sowing in warm zones gives a tender September picking.

July Garden Tasks Beyond Sowing

Maintenance is what carries the garden through July. The plants are working hardest in the heat, and small daily jobs decide the yield.

Water deeply, early, and at the base. Long, slow soaks 2–3 times a week beat daily sprinkles that train shallow roots. Water in the morning to cut evaporation and slug damage. Our vegetable watering guide gives exact volumes.
Mulch every bare patch of soil. A 5–7 cm layer of straw or compost around tomatoes, beans, and squash halves your watering and shuts down weeds in the heat. See how to mulch your garden.
Keep pinching tomato side shoots weekly on cordon varieties, and remove the lowest leaves for airflow. The technique is in our tomato pruning guide.
Watch for bolting. Lettuce, spinach, and rocket race to seed in the first sustained heat. Shade, cool positions, and bolt-resistant varieties buy weeks – see why lettuce bolts and how to stop it.
Harvest daily. Courgettes at 15 cm, beans at finger thickness, cucumbers young. The more you pick, the more the plant produces.
Scout for blight and mildew through humid spells, especially on tomatoes and cucurbits.

Common July Mistakes

Skipping the autumn garden. July is the month for brassica transplants, leeks, and chicory. Miss it and the entire winter harvest disappears – there is no second chance in September.
Sowing salad in full sun. From July onwards, lettuce belongs in the coolest, shadiest bed you have, or it bolts before it hearts up.
Watering little and often. Daily surface sprinkles collapse in the first 30 °C day. Soak deeply, less often, at the base.
Letting courgettes turn to marrows. One missed picking and the plant slows right down. Check every day in July.
Leaving soil bare. Un-mulched beds bake, crust over, and lose water fast in mid-summer heat.

Plan Your July Garden With Plantory

July asks you to run two gardens at once – nurse the summer crops through the heat while planting the autumn and winter beds that most people forget. With Plantory, you can lay out your autumn brassica and leek plantings, set reminders for each succession sowing, track your watering rhythm through heat waves, and keep your harvest log and bed map in one place so the busiest, hottest month of the year does not quietly cost you the winter garden.
