July is the perfect growing month, as long, warm days stretch out late into the evening. With vegetable gardens full of produce and borders at their peak, you’ll be busy watering, monitoring for pests and keeping on top of weeds. If you’re planning a holiday, invest in an irrigation system to look after fruit, flowers and veg while you’re away.

Here’s what you should be sowing and growing in July:

Here’s what to sow and grow in the vegetable garden this July:

In the greenhouse / indoors

  • Sow gherkins indoors by early July, to transplant outside later. Pick the fruits when small and expect to start harvesting in late summer.

Direct sow outdoors

  • Sow basil in pots to keep on your patio now and to bring indoors for the winter.

  • Make your last direct sowings of beetroot so they mature in time for autumn.

  • There is still time to direct sow fast-maturing carrots such as 'Nantes Frubund', 'Adelaide' and 'Amsterdam Forcing'.

  • Sow fast-growing herbs such as coriander, dill, and parsley directly into the ground or into containers.

  • Sow hardy corn salad directly into drills for crops throughout autumn and winter.

  • Direct sow endive for a tasty autumn crop.

  • Make more sowings of French beans and runner beans if space allows - this will extend your cropping season well into the autumn. Direct sow or start them off in small pots. Expect to start harvesting in late August.

  • • For something more unusual grow kohl rabi - direct sow it now for a crop in approximately 8 weeks.

  • Continue to direct sow lettuce seeds every three weeks for a continuous supply.

  • • July is the perfect time to start your first direct sown crops of pak choi as they’re prone to bolting if grown before midsummer.

  • Make your last sowings of peas outdoors now so that they develop before the frosts.

  • Direct sow perpetual spinach for autumn and winter cropping.

  • • Add colour to stir-fries with raddichio. Seeds can be sown directly into the soil now.

  • Make small direct sowings of radishes every few weeks to ensure a constant supply. Be sure to water frequently in hot weather and expect to start harvesting within a month.

  • Direct sow salad leaves regularly throughout the summer. Pick the leaves when small and remove any spent plants. Expect to start harvesting in three weeks.

  • • Spring cabbages such as 'Durham Early' should be sown now in a well prepared seed bed for transplanting later.

  • Continue to sow spring onions in drills outdoors for a quick crop to add to salads and stir fries.

  • • Add some colour to your plot by direct sowing Swiss chard 'Bright Lights'. This will over-winter to give a bumper crop in the spring.

  • Direct sow turnips 1cm deep. Thin seedlings to 15cm apart and keep moist. Expect to start harvesting in 60 days.

Plant outdoors

  • Plant out sprouting broccoli, spacing the plants 60cm (2ft) apart. Calabrese plants can be spaced closer together at 30cm (1ft) apart.

  • Plant out winter cabbages, allowing about 45cm between plants as they get quite big!

  • Plant out winter vegetables such as hardy cauliflowers, kale and leeks now.

  • • Plant out Brussels sprouts early this month.
