As Brits bask in the summer weather, spending more time in their gardens, they need to be wary of a particular garden hazard. Experts caution that moss, algae, and lichen, commonly found in gardens, are responsible for thousands of slips, trips, and skin reactions each year.
Research by RoSPA reveals that around 300,000 people suffer injuries in their gardens annually, with over 87,000 harmed whilst gardening or undertaking outdoor projects, and it’s often these silent hazards that pose the greatest risk. Patio and garden maintenance expert Alex Essex from Patio Black Spot Removal has highlighted five of the most common hidden injury risks lurking in plain sight. The expert also offered some top tips on how to stay safe this summer while enjoying your garden.
Slippery moss and algae:
One thing we have in abundance in the UK is rain, but these damp conditions encourage moss, algae and lichen to accumulate on patios, steps and paths, creating slick, slippery surfaces. These growths are particularly hazardous after rainfall or early morning dew, contributing to over 115,000 slips and falls in gardens each year.
Prevention tips:
Regularly clean patios and paths to remove moss, algae, and biofilm.
Use slip-resistant paving or outdoor mats in high-traffic areas.
Apply matte or low-sheen sealers on smooth surfaces.
Inspect steps and shaded areas, where algae thrive.
Repair uneven or sinking paving to prevent tripping hazards.
Wear sturdy shoes with good grip.

Lichen damage:
Despite its harmless appearance, lichen can trap moisture and gradually weaken patio surfaces, leading to uneven and unstable paving slabs. Over time, this creates trip hazards that can result in sudden falls, particularly for older homeowners or small children who may not be as steady on their feet.
Prevention tips:
Regularly inspect patios and steps following extreme weather conditions.
Remove lichen build-up before it causes damage to stonework.
Avoid aggressive pressure washing, which can loosen mortar joints.
Thorned and spiked plants:
Most gardeners will have experienced the pain of being cut by a thorn, but according to a report, 483 people were hospitalised due to thorns, spikes, and sharp leaves. Roses, brambles, and shrubs may look attractive, but their sharp thorns can easily cause cuts and skin punctures.
Prevention tips:
Keep thorned plants trimmed and well-managed.
Always wear thick gloves and long sleeves.
Exercise caution when using pruning tools on overgrown hedges or shrubs.
Toxic plant sap:
Toxic plant sap can come from common garden plants including euphorbia, giant hogweed, and even fig trees. This sap can irritate skin or even cause blistering when exposed to sunlight and it was found that 158 people required medical attention in 2023/24 from exposure to toxic or harmful plants.
Prevention tips:
Learn to recognise hazardous plants in your garden.
Wear gloves and wash your hands immediately after contact.
Seek medical advice if a rash or blistering develops.
Overgrown plants and visibility:
While we all desire our plants to flourish, overgrown plants don’t just appear untidy; they can also hide trip hazards and obscure steps and edges, leading to unnecessary falls.
Prevention tips:
Ensure walkways are free from overhanging plants.
Prune shrubs that obstruct lighting or create dark, damp areas where algae thrive.
Regularly inspect for roots or shoots lifting paving stones.
