Your gardening advice for June.

Summer is here and the garden is blooming! Will Clark shares his top 10 jobs for the glorious month of June.

Coming up roses

As we’ve seen at the Chelsea Flower Show, an English country garden filled with romantic roses never goes out of style. We’ve got some gorgeous varieties to choose from this year including the golden Arthur Bell, David Austin’s pure white Desdemona, flushed pink Olivia and Gabriel Oak which is a deep cerise.

New Rose Now In Store

Just launched at The Chelsea Flower Show this year is the David Austin Emma Bridgewater rose. This new variety is now available to purchase in store!

Happy partners

Lavender pairs really well with roses because they have similar growing conditions, like full sun and well-draining soil. Munstead and Hidcote are two very good varieties that will last up to 10 years if you don’t forget to prune them.

Purrfect plant

Nepeta, commonly known as catmint, is a hard-working perennial that will thrive in free-draining soil and full sun. In the right conditions, it can flower right through to October. The zesty scented plant is also a big favourite with our feline friends.

Flower power

Summer bedding is in full flow and the garden centre is brimming with Geraniums, Begonias, Marigolds, Lobelia and Petunias to fill your containers and hanging baskets. Make sure to deadhead regularly and add Vitax Q4 plant food to ensure the best blooms. And don’t forget to water regularly!

Blooming buddleia

Also known as the butterfly bush, the fragrant flowers of Buddleia are a wonderful source of nectar for wildlife. This undemanding plant comes in a wide range of colours including purple, blue, pink and white and even yellow.

Water wisely

If you’re planning a holiday maybe think about installing an irrigation system. Fitted with a timer, this will enable you to control when and how much your garden is watered. Alternatively ask a neighbour!

Grass roots

I like to seed the lawn now as the warmer weather means there’s a better chance of germination. Scrape any moss off bare patches and add a layer of good topsoil or lawn sand and level off before applying seed and working it into the soil. Water well.

Salad days

You only need a little space to grow a lot of lettuce. There’s still time to sow seeds directly in the ground or to speed things up buy a pack of little plug plants.

Weed control

The extra warmth and light will give weeds a boost so try to keep on top of them now to avoid being overrun in July. Shallow hoeing in dry conditions will kill most weed seedlings.

Cream of the crop

It’s a good time to start feeding your strawberries with Vitax Q4 liquid fertiliser. With any luck you’ll be enjoying freshly-picked strawberries and cream in time for Wimbledon. Happy days!

October on the Veg Plot...

October is a great month to get ahead in the veg patch, writes Ruth McNamee.

Choose a sunny sheltered spot to sow broad beans. The variety Aquadulce Claudia does well from autumn sowing. Sow a double row with seeds 20cm apart. These plants should germinate, stand over winter and quickly establish when the weather warms. The crop can be enjoyed a couple of weeks earlier than spring sown seeds.

You can start to plant out garlic this month 15cm apart in rows 30cm apart. This can be left to next month if preferred. And there is still time to plant out overwintering onions. Make a shallow drill and place the sets pointy end up 15cms apart in rows 30cms apart. Onions are ready to harvest early next summer. Try onion and garlic in big pots and keep in a sheltered spot for the best results.

October is a great month to get your permanent planting done. It’s a good time to establish your fruit and asparagus beds while the soil is still warm from the summer heat. Rhubarb and asparagus crowns will now be available in the garden centre. Prepare the beds by removing all weeds. These crops will be in these beds for many years so it helps to give them a good start.

May is the month where strawberries flower so mulch plants with straw.

Prune early flowering shrubs such as the Forsynthia and Weigela.

Direct sow basil next to tomato seedlings to help draw white fly away.

Veg seeds that can be sown outdoors include courgette, beetroot and sprouts.

Lift and divide your spring bulbs and plant where you want for next year.

Check all foliage for lily beetle and greenfly and dispose of any found.

Gardening Jobs for January

Buy seeds to be sown in January or February.

Buy seed potatoes, onion sets and garlic.

Appraise the garden for form and structure, and plan alterations and additions.

Plant window boxes and containers for seasonal colour.

Protect vulnerable plants from frost and wind damage.

Firm in any autumn-planted shrubs and border plants lifted by frost.

Knock snow off branches, especially on conifers and hedges, if they are bending under the weight.

Check stakes and ties on newly planted trees.

Remember the birds in the garden and put out food for them, especially when it’s frosty.
