Brits told 'keep a lookout' as garden's nuisances to be 'at their worst' next month

British gardeners are being urged to stay alert as the peak season for According to , June is expected to be one of the most challenging months for green-thumbed Brits, as a surge in common garden nuisances could threaten everything from delicate blooms to greenhouse crops.

"Pests and diseases will be at their worst, so keep a lookout," they said, highlighting the importance of regular garden checks and preventative care to combat the .

One of the most notorious invaders is the lily beetle, a vivid red insect known for decimating lilies and fritillaries. These beetles not only chew through leaves but also lay larvae that can quickly defoliate entire plants.

Country Living recommends carefully inspecting lily foliage and removing any beetles by hand. "If you've been growing lilies, check foliage for the dreaded lily beetle, and if found remove and dispose accordingly," they said.

In greenhouses, the threat comes in the form of red spider mites, microscopic pests that thrive in hot, dry conditions.

Their damage includes mottled leaves and weakened plants, which can go unnoticed until significant harm is done. To keep mite populations under control, experts suggest increasing humidity and improving ventilation.

"Red mite may start appearing in greenhouses, so it's a good idea to dampen down the paths each day to deter them, and keep doors and windows open for plenty of ventilation," they advised.

But the lily beetle and red spider mite are only part of a broader list of common summer nuisances. Other frequent offenders include aphids, whitefly, and fungal diseases such as powdery mildew and rust, all of which can spread rapidly in warm, moist conditions.

Garden experts stress the importance of proactive gardening throughout June. Techniques such as crop rotation, the use of insecticidal soaps or neem oil, and companion planting can help deter unwanted visitors naturally.

Regular pruning and removing diseased leaves can also prevent infections from taking hold.
