Things to be doing in the garden in July!

• Cut back faded perennial plants to keep borders tidy.

• As your penstemon flowers fade, cut them back to just above a bud to encourage more flowers.

• Cutting back growth in hanging baskets can encourage new flowers and foliage and will revive the display. Make sure you that feed your baskets well after doing this.

• Cut back hardy geraniums and delphiniums after the first flush of flowers to encourage new growth and further blooms.

• Continue to tie in and train new growth on climbing plants.

• Prune wisteria now. Just remove the whippy side-shoots from the main branch framework to about 20cm from their base (about five leaves from the main stem).

• Prune lupins to encourage further flowers.

• If you need to prune your deciduous magnolia, now’s the best time to do it.

• Divide clumps of bearded Iris so they have time to form roots and flowers buds for next year before the cold weather arrives.

• Take cuttings from your favourite tender plants for overwintering indoors. Cuttings can also still be taken from shrubs and herbaceous perennials.

• Deadhead bedding plants and perennial plants to stop them self-seeding and to encourage further flowering.

• Deadhead your roses to keep them looking tidy. Leave the flowers in place if your rose produces attractive hips (seed pods).

• Deadhead sweet peas regularly to keep them blooming. Water daily in dry weather.

• Capture seed heads from dandelions and other weeds. Collect them before they get a chance to release their seeds and spread throughout your garden.

• Keep an eye out for pests on plants, early treatment is best.

• Stop rust damaging hollyhock foliage by pruning out affected leaves and/or spraying with a fungicide.

• Look out for clematis wilt. Symptoms include wilting leaves and black discolouration on the leaves and stems. Cut out all affected material and dispose of it in your household waste.
