Gardeners are advised against pruning roses in June, despite the temptation to tidy plants during warmer weather. Experts warn that cutting roses this time of year can disrupt their growth cycle, reduce flowering, and weaken the plants.
Roses actively grow through summer, and pruning in June risks sap loss and makes them more susceptible to diseases, potentially resulting in fewer blooms throughout the season. The optimal time for pruning roses is late winter or early spring to encourage healthy growth and vibrant flowers, according to horticultural sources.
However, deadheading—removing spent petals by pinching with fingers—is encouraged during June, the peak blooming period. The Royal Horticultural Society emphasizes that deadheading promotes more flowers and keeps rose bushes healthy and attractive.
David Austin Roses outlines two deadheading stages: first, removing faded blooms to enjoy remaining flowers, and second, encouraging new growth and maintaining a compact shape. Gardeners should pinch or cut off wilted flowers just below the bloom’s base, leaving buds intact.
Other plants suited for June pruning include evergreen berberis, Buddleja globosa, and hardy fuchsias, while rhododendrons can be lightly trimmed after flowering, with heavier pruning postponed until spring.
By following these guidelines, gardeners can ensure their roses and other plants thrive throughout the summer season.
