Pruning is a vital gardening task that enhances plant form and encourages vigorous growth. While the process itself is straightforward, timing is crucial for optimal results, according to Hillier Nurseries and Garden Centres. Using clean, sharp equipment is essential to avoid harming plants and ensure proper recovery.
The experts advise: "It is always advised to make a cut above a bud or set of buds, as that is where the plant will regrow from and avoid leaving a stem which could die back. Generally, a sloping cut away from the bud will shed water from the wound and assist healing. After pruning, it's sensible to sterilise your tools to ensure there's no cross-contamination of disease between plants."
Nine Plants to Prune in July
Here are the specific plants that benefit from July pruning, as recommended by Hillier Nurseries.
Convolvulus
Trim convolvulus once flowering has finished. Cut it back hard to maintain a neat, bushy form.
Lavender
"Prune lavender to around 30cm from the ground once the flowers have gone grey," the experts said. "Cut it back to just below the flower stem but not as far as the bare wood."
Philadelphus
Trim philadelphus after flowering, if necessary, by reducing approximately 20% of its stems to ground level.
Wisteria
Summer prune wisteria by cutting back this year's long, whippy shoots to roughly five or six leaves. This promotes flowering next year.
Weigela
This easy-to-grow shrub looks stunning in the garden. Thin out older stems now to promote strong new growth.
Clematis
Early-flowering clematis can be pruned after flowering, if required, to manage size or remove dead wood.
Hedges
For hedges such as box, July is the ideal time to maintain the desired shape and prevent legginess. Privet and yew can also be trimmed to keep them tidy and encourage dense growth.
Apple and Pear Trees
Apple and pear trees need summer pruning to limit growth and improve fruit quality. Gardeners should focus on thinning out congested areas and removing dead or diseased branches for the best flowering.
Roses
Deadhead repeat-flowering roses consistently by cutting back to the first healthy outward-facing leaf to promote more flowers.
