What to Do in the Garden in August

August is an amazing time in the garden. Since summer brings an explosion of summer-flowering bulbs and perennials, you can see an assortment of colours and shapes in bloom everywhere.

While the August garden is the perfect time to put your feet up and enjoy all your hard work, don't forget about the essential gardening jobs that need to be done to keep your garden in the best shape possible.

Hydrate your Plants

In the peak of summer, heat and humidity levels are high so make sure to water your plants when needed.

Tip: The best time to water your plants is in the early morning or late evening.

Keep an Eye Out for Diseases

Stay vigilant with your plant care as high temperatures can lead to plant diseases, such as brown patches and mould. Keep an eye out for black spots on your Roses and pests like snails and slugs on your plants.

Prune Perennials and Climbers

Cut back perennials that are overgrown or have wilted flowers to tidy up their shape. Prune Wisteria and climbing shrubs such as climbing Roses, once they have finished flowering.

Tomato Care

While your tomatoes are growing, remove the lower leaves from the plant to help reduce the risk of disease. By removing these low growing leaves, the rest of the leaves have more space to enjoy the sun rays.
