Essential Garden Jobs for August

With the bank holiday weekend upon us and a heatwave on the horizon, it is the perfect opportunity to get out into the fresh air, enjoy the garden and finish off your summer gardening jobs in time for bulb planting season.

There’s lots to be getting on with in the garden, so here are our essential jobs for August.


  • Prune shrubs and climbers (Wisteria, Pyracantha) to keep your garden tidy.
  • Prune and shape hedges and evergreen hedges before they stop growing in the autumn.
  • Cut long-flowering perennials to the ground, such as Hardy Geraniums.
  • Trim back lavender after it has finished flowering.


  • Sweep your patio and trim any small weeds as they germinate.
  • Hoe the soil to keep weeds down. This should be done in warm, dry conditions to ensure that any weed seedling left on the surface will dehydrate and die.
  • Remove pond weeds with regular debris cleaning.


  • Water plants that need it regularly.
  • Water in the morning or late afternoon/evening to prevent the water evaporating in the heat.
  • During hot spells, splash water on the floor of your greenhouse to bring the humidity up.

 Lawn Care

  • Mow weekly but reduce frequency and raise blades if the weather is hot and dry.
  • Lawn weeds are usually prominent and need pulling or treating.
  • Apply a high phosphate fertiliser at the end of the month to benefit the grass roots.


  • Keep bird baths topped up with fresh water.
  • When deadheading, leave some flower seedheads as food for birds and small mammals.
  • Deadhead Buddleia bushes to keep them flowering into the autumn for bees and other insects.

Bulb planting

  • Start ordering your spring-flowering bulbs now. You can start planting bulbs such as Narcissi, Crocus and Hyacinths from September onwards.
  • Order Prepared Hyacinth and Indoor Narcissi bulbs and pot them up so that they will be ready for December.

  1. I just wanted to say thank you very much for your helpful website.
    I am recently retired and have always enjoyed the heavenly experience of being in a garden but never, previously had the time to develop my own tiny piece of land.
    I am now beginning to create my own little piece of heaven and much of that is down to people like yourselves who provide not only the plants to grow but, very important for me, advice on how to look after them.
    You are much appreciated!

  4. Hi I’m ordering the alpine perennial rockery 30 plant selection. Is this suitable for South Wales please?
    I want weed cover and lots of colour😊

    1. Hi Anne, yes they are. Remember to water and feed regularly during the growing season and avoid the soil from drying out by keeping a close eye on watering. Thanks for your question!

  5. What is the best mulch for weed control please? Can I use grass mowings that have no seed tops?
    How about hay?

    1. Hi Anne, Among the best mulch materials are leaf mould, garden compost, spent mushroom compost, wood chippings, processed conifer bark, well rotted manure, straw (for strawberries) and seaweed. Yes you can use grass clippings too. If using fresh clippings as mulch, only lay a layer of ¼ inch thick. This will allow the grass to start to break down before it begins to smell or rot. Thicker layers have a tendency to remain too wet and can invite mold and create smelly decay issues. Thanks for sending in your question!

  6. Thank you for the advice, it’s really helpful. Weeding is definitely essential in August, especially because it tends to be muddier and rainy in September so much more difficult to get the job done. Thanks for sharing!
