What To Do in the Garden in July

Long, hot days and beautiful blue skies are frequent throughout the entirety of July. Perennials will be in full bloom and gardens will be alive with the sounds of butterflies, bees and insects feeding. Fruiting plants and vegetables are plentiful providing our kitchens with home grown produce to feast on throughout the long summer evenings.

Much of the work that needs to be completed in the garden in July is a continuation of your hard work from June. The warm weather brings more colour into the garden and causes repeat flowering of some of the most popular British garden plants. Take a look at a few of the things we recommend taking care of in the garden throughout July.

What To Do in the Garden in July

Plants and Flowers:

  • Continue the good work started in June and keep on top of the blooms reaching the end of their cycle. Deadhead bedding plants and repeat flowering perennials to encourage more flowers to develop. Particularly focus on Roses and Sweet Peas throughout July.
  • Use a similar technique for your hanging baskets to encourage repeat flowering, keeping your garden in bloom for longer.
  • As the warm weather encourages continued growth continue training climbers on Clematis and Honeysuckle to maximise the area decorated by their blooms.
  • Prune Lupins to encourage new growth and collect seeds to plant next year.
  • Ensure that plants that have been tied to reduce wind damage are not tied too tightly after more growth has taken place, loosen and reposition where necessary.

Lawn Care:

  • Keep up with lawn feeding, particularly during dry spells.
  • For long periods of dry weather, to help with moisture retention, leave cut grass on top of the lawn and cut at longer intervals and higher heights.
  • Trim lawn edges to neaten the appearance of the lawn.

In the fruit and vegetable patch:

  • Warm July temperatures will cause tomato plants to bear and ripen fruit quickly. Trim tomato shoots each week and cut off those beneath the lowest ripened fruit to stop competition.
  • Tomato plants should be regularly fed with specific food at this time of year to ensure the plant thrives whilst producing fruit.
  • Courgettes throughout July should be picked whilst they are young to encourage more growth and repeat harvest.
  • Beetroot, peas, carrots, potatoes, salads and tomatoes should all ripen and be picked at this time of year.
  • Continue thinning out fruit trees of excess fruit to encourage better quality of harvest.
  • Peg runners on strawberry plants for increased crop numbers next year.

Pests and Weeds:

  • As July causes a boost in fruit production place meshing around fruit trees and the vegetable garden to deter birds from stealing your harvest.
  • For mature weeds cut seed heads from the plant before the seeds are released and spread around the garden. Dandelions should be trimmed and a weed killer applied to stop growth.
  • Keep on top of slug and snail repellents to stop loss of produce. Always apply after following the instructions of the particular product you are using and keep out of reach of children and pets.
  • Whilst hydrangeas are in bloom keep an eye out for hydrangea scale, a sap sucking insect which will cause leaf loss and failure to grow.
  • Look after your Ladybird, Hoverflies and Lacewing population as they will help to control the number of aphids on your plants and flowers.
  • Regularly weed through borders to reduce the competition for your flowering plants and shrubs.

Watering Tips:

  • As July will bring hot temperatures dampen the greenhouse floor each morning to help reduce stifling temperatures.
  • It is best to water plants in the early morning and in the late evening to reduce water lost through evaporation and improve water retention.
  • Ensure fruiting plants and vegetables are constantly moist to improve yield.
  • Use water butts and rainwater to water plants where possible rather than tap water.
  • Keep bird baths and water bowls topped up to provide for wildlife and insects each day.


  • Remember to plan ahead for your plant watering if you are going on holiday to ensure your garden is still thriving on your return.
  • Take note of what is doing well in your garden this year and what you would like to change and improve on next summer. It is easiest to do this in July when the majority of your plants are in bloom, providing fruit and are at the height of their growth cycle.

Something for the little ones:

Work on creating a ladybird paradise for your garden together by creating a designated area including plants such as Fennel, Dill, Marigold and Angelica. Creating a Ladybird hotel is also a great activity for the little ones which can be left in a sunny spot in the garden to encourage these handy little aphid eaters to take up residency in your garden.

July is a perfect opportunity to see the vast beauty that your garden has to offer.
