What to Sow in July: Vegetables, Herbs & Flowers to Plant Now

Midsummer has a sneaky reputation: the garden is in full swing, so it feels like sowing season is over. It is not. July is one of the most rewarding months to sow — fast salads race out of warm soil in days, there are last calls for autumn roots and greens, and it is the classic month to start biennial flowers for a spectacular display next spring. Here is exactly what to sow in July, and how to keep those sowings happy in the heat.

• Fast salads keep sowing every 2–3 weeks
• Autumn harvests last calls for roots & beans
• Biennial flowers sow now, bloom next spring
• Midsummer rule keep seedbeds moist & shaded

Why July sowings are so satisfying

Warm soil is a germination machine. Seeds that dawdle for three weeks in a cold April bed can be up in three days now, and because the soil is workable everywhere, most July sowing is easy direct sowing — no windowsills, no modules, no fuss. The only real enemies are drought and heat-stressed seedlings, and both are simple to manage with a watering can and a little shade.

Vegetables to sow in July

• Salads on repeat — lettuce (choose bolt-resistant types and give them light shade), rocket, radishes and baby leaves. Short rows, every couple of weeks.
• Roots for autumn — early July is the last comfortable call for fast carrots and beetroot; turnips can go in all month for tender autumn roots.
• Greens that love a late start — pak choi and other Asian greens bolt far less now the days are shortening, and chard sown now crops into winter.
• The autumn-salad classics — July is the traditional month for endive and chicory, with corn salad following from late July.
• One last bean run — sow dwarf bush beans in the first half of the month for a fresh flush of pods in September.
• Winter thinkers — kale sown now makes sturdy plants for autumn and winter picking, and bulb fennel is less likely to bolt from a July sowing.

If a packet promises speed, believe it this month — the whole fast-growing range is in its element, and the succession sowing rhythm keeps it all coming steadily instead of all at once.

Herbs to sow in July

Heat-sensitive herbs actually get easier from now on. Coriander sown from mid-July bolts far less than spring sowings, dill loves warm soil, and chervil sown late in the month gives tender autumn leaves. Sow parsley now and you will still be picking it in winter — it germinates much faster in July's warmth than it ever does in March. Browse the full herb seed range, and check the herb sowing calendar for exact windows.

Flowers to sow in July: think next spring

This is the sowing that separates the good spring gardens from the unforgettable ones. Biennials sown in July build strong roots this year and flower magnificently next May and June:

• Foxgloves — sow now for towering spires next summer. Our Dalmatian Peach foxglove even flowers reliably in its first year from an early sowing.
• Forget-me-nots — a July sowing of myosotis gives clouds of blue under next spring's tulips.
• Wallflowers, sweet william & honesty — the classic cottage biennials, all happiest sown in midsummer.
• Perennials from seed — delphiniums and other border stalwarts sown now establish before winter and flower next year.
• Still want colour this year? — a quick sowing of calendula in early July flowers by September and keeps going to the frosts.

The flower sowing calendar shows every window at a glance.

One July weekend: a simple sowing plan

1. Clear a spent crop Lift the last early potatoes, peas or bolted lettuce — that gap is prime real estate.
2. Refresh the bed Rake level and work in a little compost — no digging marathon needed.
3. Water the drill first Soak the seed drill before sowing, then cover with dry soil to lock the moisture in.
4. Sow short rows A little of each: salads, roots, autumn greens and a tray of biennials.
5. Shade & note the date Shade new sowings in a heatwave and jot down when the next short row goes in.

Sowing for autumn, or sowing for spring?

Every July sowing falls into one of two happy camps:

Common July sowing mistakes

• Sowing into bone-dry soil — seeds need constant moisture to germinate. Water the drill first, and keep beds damp with the tips in our watering guide.
• Letting lettuce cook — lettuce seed can refuse to germinate in very hot soil. Sow in the cool of the evening, in light shade.
• Missing the biennial window — wait until autumn and foxgloves or wallflowers will sulk; July and early August is their moment.
• Starting slowpokes too late — tomatoes, squash and other long-season crops sown now will not make it. Save those seeds for spring.
• One giant sowing — little and often beats a glut every time; that is the whole art of succession sowing.

Frequently asked questions

Is July too late to start a vegetable garden?
Not at all. Salads, radishes, turnips, beans and Asian greens all deliver a real harvest from a July start — pick anything from the fast-growing vegetables and you will be eating home-grown food by September.

What flowers can I sow in July?
It is the classic month for biennials — foxgloves, wallflowers, sweet william, forget-me-nots — plus quick annuals like calendula for colour this same season.

Can I sow during a heatwave?
Yes, with tactics: sow in the evening, water the drill before sowing, and shade the row until seedlings are up. Very hot soil pauses germination for a few crops (lettuce especially), so a shaded spot helps.

What can I sow in pots in July?
Almost everything fast: salad leaves, radishes, dill and coriander all thrive in containers — as do baby beetroot and dwarf beans in a deeper pot.

July rewards the gardener who keeps sowing. Browse all our seeds and the rest of our growing guides — and if you sow one thing this month, make it a row of something you will eat in September.
