What to Do in the Vegetable Garden This July

Published on July 11th 2020

This month, there's some harvesting, weed control and a need to keep a sharp eye out for troublesome pests and diseases.
Be sure to check out my weekly gardening tips for other memory joggers in July.

Home grown vegetables

  • Pick beans and peas early - when they are young. If you have a lot and don't have the time to freeze them, give them away to a friend or neighbour. Hopefully, they'll repay the favour!

  • Watch out for pests and diseases. Aphids- in all their colour forms- can multiply alarmingly fast! Keep a lookout for them on your climbing beans. A well-directed squirt of water to remove them may be all that is needed.
  • Mildew and other diseases can also quickly get a hold, and preventative treatment is the best form of attack. Spray prone plants with Fungus Fighter or other suitable fungicides.
  • Sow more courgettes. These will be fresh and young ready to replace those you planted earlier and those suffering from mildew.

  • Slug and snail protection gets easier this month but watch out for them moving into cabbage heads.
  • Cover your Brassicas with butterfly proof netting to prevent caterpillar attack.

Home Grown Fruit

  • If your fruit trees have a heavy crop developing, then it is wise to thin now. This will improve the fruit quality and the size too — thin apples to just two fruits per cluster and pears to a single fruit.
  • If plums have a massive crop set, then a drastic removal of excess fruits is needed to prevent small fruit and branch breakage later. Silver leaf disease often starts with a broken branch.
Plums on a branch
  • Wall or fence-trained gooseberries, redcurrants and white currants will need side shoots cut back to leave 4-5 leaves. This reduces vigour but also improves fruit bud production for next year's crop.
  • Plums, cherries and other stone fruits of all training styles should be pruned now but never in the winter.

Weed control

  • Regular hoeing between plants in borders and the vegetable patch will keep annual weeds under control and also reduce drying out of the soil.
