July 2026 Allotment Checklist 

July is one of the most rewarding months on the allotment. The hungry gap is behind us, crops are filling baskets daily, and plots are bursting with colour and life. However, July can also bring prolonged dry spells, heatwaves, water restrictions, and an increase in pests and diseases.

This is the month when regular attention pays dividends. A little time spent watering wisely, harvesting frequently, and planning ahead for autumn and winter crops will keep your plot productive throughout the rest of the season.

Soil Preparation & General Maintenance

Keep Hoeing - A sharp hoe remains one of your best tools in July. Regular hoeing on dry days removes young weeds before they establish and reduces competition for valuable water and nutrients.

Mulch, Mulch, Mulch  -If there is one task that makes a difference during hot weather, it's mulching. Apply a thick layer of compost, leaf mould, grass clippings (in thin layers), or well-rotted manure around thirsty crops such as:
  • Courgettes
  • Pumpkins and squashes
  • Sweetcorn
  • Beans
  • Tomatoes
  • Outdoor cucumbers
Mulching can dramatically reduce evaporation and help soils retain moisture for longer.

Water Efficiently
-With many areas experiencing increasingly dry summers, water conservation is more important than ever.
  • Water early in the morning or late in the evening.
  • Water the soil, not the leaves.
  • Use watering cans rather than sprinklers where possible.
  • Install water butts if you haven't already.
  • Consider using grey water on ornamental plants where appropriate.
  • Deep watering once or twice a week is generally more effective than frequent shallow watering.
  • Watch for Signs of Heat Stress
Leaves may wilt during the hottest part of the day. Check whether plants recover in the evening before assuming they need more water. Overwatering can sometimes cause as many problems as drought.

Vegetable Tasks

Feed Hungry Crops
Many crops are now reaching peak production and benefit from regular feeding.
Feed weekly with a high-potash liquid feed:
  • Tomatoes
  • Peppers
  • Chillies
  • Cucumbers
  • Courgettes
  • Aubergines
  • Sweetcorn also benefits from additional feeding during dry periods.
Continue Succession Sowing
Don't let empty spaces appear on your plot.
Sow:
  • Lettuce
  • Rocket
  • Mizuna
  • Pak choi
  • Spring onions
  • Beetroot
  • Turnips
  • Coriander
  • Dill
Small, regular sowings provide a continuous harvest rather than a glut all at once.

Start Thinking About Winter
July is the perfect time to prepare for colder months.
Plant out:
  • Kale
  • Winter cabbage
  • Purple sprouting broccoli
  • Brussels sprouts
  • Leeks
These crops need time to establish before autumn arrives.

Harvest Frequently
Regular harvesting encourages continued production.
Pick:
  • Courgettes while small
  • Runner beans every few days
  • French beans regularly
  • Cucumbers before they become oversized
  • Peas while pods are tender
A neglected crop can quickly stop producing.

Earth Up Leeks and Celery
Continue earthing up leeks to encourage long white stems. Self-blanching celery may also benefit from additional soil or protective wrapping.

Fruit Tasks

July is one of the busiest fruit-harvesting months of the year.

Harvest Soft Fruit

Pick regularly:
  • Strawberries
  • Raspberries
  • Gooseberries
  • Currants
  • Cherries
  • Early blueberries
Frequent picking improves quality and reduces losses to birds and wasps.

Protect Fruit Crops
Birds quickly discover ripening fruit.
  • Use netting carefully to protect:
  • Cherries
  • Blueberries
  • Currants
Ensure netting is securely fitted to prevent wildlife becoming trapped.

Summer Prune Trained Fruit Trees
Prune:
  • Cordons
  • Espaliers
  • Fans
Reducing new side shoots helps maintain shape and encourages fruit bud formation for next year.

Thin Apples and Pears
Where fruits are clustered heavily, remove smaller fruits to improve size and quality while reducing the risk of branch breakage.

Finish Harvesting Rhubarb
Take the final harvests of rhubarb this month and allow plants to rebuild energy reserves for next year.

Greenhouse & Polytunnel

Ventilation Is Essential Temperatures can rise dangerously quickly under cover.
  • Open vents daily.
  • Leave doors open where safe.
  • Install automatic vent openers if possible.
  • Shade glass during extreme heat.
Support Climbing Crops
Continue tying in:
  • Tomatoes
  • Cucumbers
  • Melons
  • Cucamelons
Remove unnecessary side shoots on cordon tomatoes.

Prevent Blossom End Rot
Inconsistent watering causes many tomato problems.
Maintain:
  • Even soil moisture
  • Regular feeding
  • Good ventilation
  • Avoid allowing compost to completely dry out.
  • Check for Pests Daily
Watch for:
  • Red spider mite
  • Whitefly
  • Aphids
  • Thrips
Early intervention is far easier than dealing with a major infestation.

Flower Tasks

July is peak flowering season.
Deadhead Regularly
Remove spent flowers from:
  • Sweet peas
  • Cosmos
  • Dahlias
  • Calendula
  • Marigolds
This encourages continuous flowering well into autumn.

Harvest Cut Flowers
The more you pick many annual flowers, the more blooms they produce.

Support Pollinators
Keep flowering plants around your plot, including:
  • Borage
  • Calendula
  • Cosmos
  • Lavender
  • Nasturtiums
  • Sunflowers
These provide valuable nectar during summer and help improve pollination of fruiting crops.

Pest Control & General Allotment Maintenance

Potato and Tomato Blight
Warm, humid conditions increase the risk of blight.
Watch for:
  • Brown patches on leaves
  • White fungal growth
  • Blackened stems
Remove affected foliage immediately and dispose of it responsibly.

Cabbage White Butterflies
  • Inspect brassicas frequently for eggs and caterpillars.
  • Protect crops using insect-proof mesh or netting.
Aphids
Large colonies can develop rapidly in warm weather.
Encourage natural predators such as:
  • Ladybirds
  • Lacewings
  • Hoverflies
  • Wasps
Wasps become increasingly noticeable around ripening fruit. Harvest regularly and remove damaged produce.

Final Thoughts

July is often the month when allotments are at their most productive and beautiful. The key to success is consistency. A little time spent harvesting, watering, feeding, and observing your crops every few days can make the difference between a good season and a great one.

Enjoy the rewards of all your hard work, share surplus produce with neighbours and friends, and remember to take time to sit back and appreciate everything your plot has achieved so far this year.
