What to do in the garden in August

You never know what the great British weather will bring so our gardens may need extra attention to get the best from your planting and growing earlier in the year. August is the month when flowers are at their best and sunshine, BBQs and outdoor fun is the tonic we all love!

What to do in the garden in August

Vegetables

August is a great month to reap the benefits of all those vegetable seeds you planted in the Spring. As well as harvesting veggies for tasty meals, here's a few other things to do:

  • Feed tomato plants weekly with liquid plant food and remove lower leaves to encourage growth
  • Cut back herbs to encourage new growth and dry or freeze for later use
  • Start harvesting carrots and beetroot planted in the Spring
  • Main crop potatoes can also be harvested - store them in sacks or paper bags out of the light
  • Pick runner beans as soon as they're a decent size so they don't get stringy

There are some veggies you can still plant this month:

  • August is the last month to sow Spring cabbages outside
  • Keep sowing salad leaf seeds for a continuous supply
  • Fast-growing radish can be sown up to the end of August

Flowers

August gardens are typically full of dazzling displays of colour and provide that much-needed space to relax with family and friends. To keep the colourful blooms going here's a few ideas for what plant seeds to sow now:

  • Hardy annuals such as marigolds, cornflowers and poppies can be sown at the end of this month for early colour next year (cover with a cloche or fleece if winter is severe)
  • For colour in the cooler months sow winter-flowering pansies now
  • Get a gorgeous early Spring display of colour by sowing Viola this month

With a little bit of effort here and there you can also keep on top of the flowers that are blooming in the garden right now:

  • Keep camellias and rhododendrons thoroughly watered this month to help next year's buds develop
  • Use liquid plant food to keep flowers and plants healthy
  • Dead head bedding plants and perennials to encourage further blooms
  • Trim lavender plants after they've flowered to keep them tidy
  • Tie back long rose shoots to prevent weather damage

Watering

In this country the weather can be unpredictable to say the least! In August we can get the heaviest of downpours and then ten minutes later it's boiling hot and the ground is dry. So, how do you keep the garden looking good with this topsy-turvy weather? Make sure that your plants and flowers don't dry out in the heat by watering them regularly. If you water plants when the sun has gone off them in the evening or in the early morning the roots will retain more moisture.

Using rainwater is a definite environmental win for gardeners and is easy to do with a water butt. Collecting water this way also means you'll have something to water the garden with even if there's a hosepipe ban! You can use grey water too but be careful! This waste water from your washing-up, shower and bath can be useful for short-term watering of non-edible plants especially during a summer drought.

Watering the lawn in a heatwave

We often find ourselves with a parched, sad-looking lawn after dry weather, and you’ve probably found yourself wondering if it will ever come back to life. The good news is that most grass is very hardy and will start to turn back to its former glory as soon as we start getting some regular rain again. If you want to keep your green lawn, there’s nothing for it but to keep it hydrated before it starts to show excessive signs of stress – but you must always check before switching on your hose pipe for any restrictions that may be in place in your area. Be sure to follow these tips for the most effective way to look after your lawn in a heatwave:

  • Raise the height of your lawn mower to avoid weakening the grass.
  • Leave grass cuttings on the lawn to act as a mulch to keep any moisture in the soil
  • Don’t water lawns any more than every 7 – 10 days, and only when the soil is dried out
  • If the ground is hard, aerate the soil before watering so more water can get down to the roots.
  • Remember it will be green again when the rain comes back!

Outdoor Dining

Make the most of cooking outdoors and enjoying every second in your garden before the weather starts to cool off. Fire up the BBQ, whether it’s a disposable BBQ for days out, or a massive family grill perfect for summer feasts. Don’t forget all your barbecue accessories, like coal, utensils skewers for kebabs and of course BBQ brushes for cleaning up when you’re done.

August is great for getting out there and enjoying your little slice of the great outdoors, so make sure you have somewhere to relax in comfort and style. Find time to slow down and just be. Put your feet up – you’ve earned it. If you haven’t already, choose a spot (or a few places if you’re lucky) where you can put some outdoor furniture – perfect for extending your living space outdoors.

Why not grab some of our gorgeous outdoor furniture cushions. They're made with water repellent polyester so will dry quickly and they're hard-wearing, too! With a soft cotton removable cover, you can even use them indoors.

Keep the kids entertained

Enticing the kids outdoors and away from screen time is no mean feat but when will there be a better chance for achieving it than over the summer holidays? Arm yourself with a range of fun garden games everyone can get involved with for some healthy competition. And a paddling pool is just the thing for some fun water games when it’s a hot day. You’re sure to be onto a winner – who doesn’t love to be outdoors splashing around, exploring and playing games? And if you’re looking to create some fun shade for little ones, how about their very own play house?]It's so important to keep your skin safe and protected in the sun and that's especially true for the little ones as well as the whole family. Did you know that even on mild days when there's cloud cover, you still need to protect your skin? The sun's rays are very powerful! Pop on a hat and sunglasses and lots of sun cream. Our wilko sun creams are 5-star UVA rated - that's a little win!
