As June arrives and garden enthusiasts begin sprucing up their outdoor spaces, horticulturist Peter Dowdall, known as The Irish Gardener, is urging caution. With over 30 years of experience, Dowdall advises against trimming hedges this month because many birds are still actively nesting.
Speaking to this publication, Dowdall said: 'I would never recommend cutting hedges before the end of August. People are often surprised at how late birds continue nesting and raising young. What looks like an ordinary hedge can still be full of active nests during summer, and trimming at the wrong time can destroy them.'
Dowdall also emphasised that plants often thrive with less interference. 'Gardening is not always about doing more. Very often the best gardeners are the ones who learn when not to act. A slightly looser, more natural garden is often healthier, more resilient and far better for wildlife as well,' he explained.
He stressed the importance of focusing on improving growing conditions rather than merely keeping things tidy, especially in the face of climate change. Healthy soil is fundamental, and mulching around plants can help suppress weeds, reduce evaporation and improve soil structure over time.
Additionally, Dowdall warned against pruning hydrangeas even if they look unruly, as floppiness is often due to stress or lack of water, not a need for cutting. He also highlighted a common watering mistake: watering little and often. Instead, a single deep soak is far more effective, and watering should be done in the morning or evening to avoid evaporation.
