Your Garden in Summer

Your Garden in Summer

With the warm sun (fingers crossed) beating down as you lovingly tend to your flowers, veggies and fruit; summer is a wonderful time to spend long lazy days in the summer. Your garden should be looking its best during the summer months, so a lot of the jobs are simple maintenance and upkeep tasks. Meaning you get more time to sit back and relax, with a nice, cooling drink in hand.

Flower Beds

Guard the Borders – June

The extra hours of sun mean your garden may be visited by some unwelcome guests during June. This makes it important to ensure you hoe the boarders of the garden and any gaps in paving to stop unwanted weeds from sprouting. The Capital Gardens Weeding and Weed Control section can help you keep on top of all weeding and removal tasks.

Prune the Spring Flowers – June

As spring draws to a close, it is time to prune the spring-flowering plants of your garden – helping prolong their life and keep their appearance. The Capital Gardens Tools and Machinery range contains a number of products well-suited to pruning the spring flowers and keeping your garden looking neat and beautiful.

Plant out the Summer Bedding – June

And the last task is perhaps the most highly-anticipated – the chance to finally plant the summer bedding. Getting the garden looking its best and brightest – the summer bedding is one of the most rewarding garden jobs.

Lift and Divide Overcrowded Bulbs – June

If it starts to get overcrowded under the topsoil, the bulbs will be competing for vital nutrients – running the risk of none of the bulbs growing strong and healthy. Divide the bulbs so an appropriate amount remains in any one place.

Check for Clematis Wilt – July

Check all shoots, buds and leaves for signs on Clematis Wilt – removing any occurances to reduce the risk of it spreading. The affliction often manifests itself in the wilting and dying of leaves, buds and shoots. When affect leaves and shoots are identified and removed – make sure they are properly disposed of in domestic waste.

Take Cuts from Tender Plants – July

If you want to over-winter your favourite plants indoors, now is the time to take the cuttings and move them into your house.

Deadhead the Perennials – August

Regularly deadheading flowering plants can help them continue to bloom and blossom. Although it may seem counter-intuitive to prune away beautiful flowers, this process can help ensure your perennials continue to produce beautiful flowers for longer.

Collect the Seeds – August

It’s never too early to be planning for next summer’s garden – so collect the seeds of the plants which have grown strong and beautifully this year. Keep these organised and ready to plant again next year for another bumper crop of beautiful flowers.

Plant Trees, Shrubs and Perennials – August

Planting trees, shrubs and perennials will help them take root and grow stronger over the coming months. Ensure they are well watered and maintained for long-term gains.

Dead-Head Lilies – August

It can be difficult to force yourself to dead-head beautiful lilies, but it will be worth it. This will help produce an even more beautiful flower display next year.

Veggie Patch

Pinching the Tomatoes – June

Pinching out the side shoots on any tomato plants you are growing can help concentrate the plant’s growth towards bearing fruit. This simple task can help your plant grow bigger and more delicious tomatoes.

Harvest the Salads and Potatoes – June

Just in time for the start of barbecue season, June is the ideal time to start harvesting many salad items such as lettuces and radishes. Some early potatoes may also be ready to be harvested at the start of the month.

Harvest Courgettes – July

If you have been growing courgettes for summer veggie dishes and BBQ side plates – now is the time to dig them up before they grow into marrows. If you leave the courgettes to grow and develop into marrows, the flesh within can often grow a little bit tougher and lose some of the flavour. However, if you are trying to grow prize marrows – keep them in there.

Plant the Christmas Spuds – July

Now is the right time to plant any potatoes you are hoping to harvest in time for Christmas dinner. Make sure you plant plenty of potato seeds if you are planning on entertaining a lot of guests this year who will be expecting plates full of roast, boiled and mashed potatoes. Plant the seeds in pots or bags so they can be brought under cover before the first frosts hit. The Botanico Spud Bag is the perfect medium in which to grow potatoes in time for the Christmas roast.

Harvest Sweetcorn and Other Veggies – August

The vegetable patch will start bearing gifts at this stage of the year, and it is the perfect time to start harvesting them. This is another job which can be shared with the children and grandchildren, giving them a better understanding of where their food comes from.

If you are harvesting potatoes – it is important to ensure you find and dig them all up. You don’t want any volunteer potatoes next year!

Cut Back Herbs – August

This may be the last chance you’ll have to cut back herbs and encourage fresh growth of another crop of tasty leaves before the frost takes over. These herbs could come in handy over the winter months when you’re looking to make delicious, warming stews.

Tie Up Tomatoes – August

Cordon tomatoes may be starting to outgrow their support stakes. Keep these tied down and trimmed to ensure they don’t weaken. Remove all lower leaves to help air circulate and promote healthy growth.

Fruit Garden

Protect Developing Fruits – June

Developing fruits will attract the interest of birds and squirrels, so be sure to protect the blossoming plants with a little netting. Making sure any bird and squirrel feeds are full of treats will also help keep their attentions away from your developing fruits.

Thin Out Fruit Trees – June

Some fruits will start to drop from branches (the June Drop), but it’s best to give this process a helping hand by thinning out congested branches. This will help bigger, juicier fruit grow over the summer.

Feed Citrus Fruit Trees – July

Starting in July, it is important to feed lemon trees and other citrus fruit trees with special citrus fertiliser. This will help promote the growth of big juicy citrus fruit for your morning juice.

Check for Sawfly Larvae – July

Most commonly found on the branches of gooseberry bushes, sawfly larvae are devastating little creatures, capable of completely stripping foliage in a matter of days. You can remove the larvae by hand or using a jet of water.

Generously Water Raspberries – July

As the heat grows stronger during the month of August, the shallow roots of raspberry plants will appreciate being generously watered. So make sure you give them plenty to drink.

Harvest the Apples – August

Early-cropping apples will now be ready to eat this month. A great job to share with the children and grandchildren – there are few finer treats on a hot summer’s day than a juicy yet crunchy apple plucked fresh from the tree.

And Cherries, Plums, Peaches, Nectarines and Apricots – August

Towards the end of the month, all these beautiful fruits will be ripe and ready for the plucking. Delicious sweet treats to be enjoyed whilst soaking up the sun in the back garden.

The Lawns

Feed the Grass – June

Despite the rainfall we are ‘enjoying’, it is almost guaranteed that we are just around the corner from a hosepipe ban. This can make food for the lawn scarcer and compromise the health of your grass. Keep the grass sustained and healthy by treating it to some quick-acting summer feed.

Let the Indoor Plants Out – June

If you have been keeping any plants in your conservatory or on your windowsills throughout the spring – now is the perfect time to get them outside. This will give them a chance to benefit from direct sunlight and offer a little extra colour and beauty to the garden.

Adjust Mower Blades – July

If the UK is currently enjoying a dry spell, your lawn may be suffering. Adjust the blades on your lawn mower so they are higher – this will reduce the stress on the grass, reducing the risk of breakages and damage.

Increase Hydration – August

Keeping all plant life watered and hydrated is vital during the month of August. This includes the watering of all plants in containers and especially new plants. Try to use grey recycled water or stored rainwater wherever possible, to reduce the amount of fresh water which is used during the long, hot month.

Diligent Weeding – August

August is one of the months you’re most likely to spend relaxing in the garden – so you don’t want your views ruined by unsightly weeds. This makes it even more important to ensure your regular weeding jobs are carried out with extra diligence.

Around the House

Note the Successes and Failures – July

Judge which summer-blooming flowers, veggies and fruit have been successful this year, and keep a record. This will help you plan future gardens, and increase the chances of producing beautiful summer displays year after year.

Freeze Berries – August

If you want to enjoy beautiful raspberries, blackberries or loganberries throughout the winter (just think about hot fruit crumbles on a snowy day), now’s the time to pop them in the freezer to store them for months.

Start Sketching – August

On a lovely sunny day, get out in the garden and start sketching next year’s plans. Taking into account what has worked this year, you’ll be able to draw inspiration for next year’s plan.
