June Tips for your Garden

“It is the month of June, the month of leaves and roses, when pleasant sights salute the eyes and pleasant scents the noses.” – Nathaniel Parker Willis

After the sunniest spring on record, it’s a wet start to June this year! Don’t let that dampen your spirits, it’s a great time to be a gardener!

Once the risk of frost has passed it is safe to plant out all your summer bedding plants into borders, containers and hanging baskets.

Lift and divide clumps of snowdrops and bluebells once the leaves start to yellow.

Remember to deadhead roses if they are repeat-flowering types, to encourage more flowers.

Plant out cannas and dahlias once the danger of frost has passed.

Divide hostas as they come into growth.

Protect lilies, delphiniums, hostas and other new shoots from slugs and snails.

Deadhead and cut back oriental poppies after flowering. Cutting them close to ground level will stimulate new foliage.

Train and tie Sweet Peas into their supports to encourage them to climb making a good display of flowers.

Keep tubs, hanging baskets and alpine troughs well-watered. Use collected rainwater or recycled grey water wherever possible.

Cut back tender shrubs such as Penstemon, Caryopteris and hardy fuchsias after danger of frosts has passed.

Rhododendrons can be lightly pruned after flowering. More severe pruning should wait until the following early spring.

Clip evergreen hedges such as Privet, Box and Yew whilst they are in active growth.

Prune deciduous magnolias once the plant is in full leaf. If this is done in winter, when the tree is dormant, dieback can occur, and pruning in late winter or spring can result in bleeding. Midsummer is therefore recommended.

Prune out any remaining frost damage from affected evergreen shrubs.

Hoe borders to prevent annual and perennial weeds from spreading and seeding themselves.

As soon as the risk of frost has passed plant out tender vegetables such as courgettes, squash, tomatoes and sweet corn.

Pinch out any side shoots from your tomato plants and feed once the first truss is setting fruit.

Apply grease bands to young fruit trees or paint grease strips on to larger trees to protect crops from damage caused by earwigs and ants.

Clean and top up birdbaths regularly, especially in warm dry weather. Keeping a birdbath clean helps to prevent birds catching diseases.
