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.
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.
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.
There is a garden philosophy: If you like it, it’s a flower; if you don’t, it’s a weed. It’s hard to have compassion for weeds, but they’re just plants growing in places where they’re not wanted. One approach is to pull the weeds out by hand but why not try a completely different approach? A thick mass planting of ground cover plants can control weeds by keeping the direct sunlight off the soil, which can cause weeds to germinate and can compete with the weeds for water and nutrients.
Here’s a guide to identifying the garden enemies in your garden.
Some are annuals and have a one-year life cycle that ends with them setting seeds for the next generation.
Others are perennials, like dandelions (having a lifecycle longer than one year). You may need to eradicate the main root of these to remove them.

To help you plant your ground cover this spring, here is our handy step-by-step tutorial, so that you can get the best performance and results from your garden this summer.
Which plants work the best for weed control?
Dense evergreen varieties are the best option if your main aim is to suppress weeds.
What do i need to do to prepare for planting?
Be sure to fully eradicate all existing weeds before you plant, especially perennials such as dandelions, as they will become near impossible to remove once your ground cover is planted.
Will the ground cover kill my other plants?
Place decorative rocks or stepping stones between ground cover and perennials to maintain a barrier for spreading stolons, or above ground perennials.
When planting more than one ground cover variety, spread mulch between the plants to conserve soil moisture and reduce unwanted plant growth.
What aftercare is required for ground cover?
Spread netting or old sheets over ground covers during autumn leaf drop. It can be difficult to rake leaves out of thick ground covers, and allowing the leaves to sit can create unhealthy conditions.
