Gardeners urged to stop leaving pots and containers on the ground

As stormy weather rolls into the UK, gardeners are being warned about a surprisingly common mistake that could cost them their beloved plants. As the weekend is set to bring torrential rain and strong winds across the UK, many plant-lovers may unknowingly be setting their gardens up for disaster by making one simple and common mistake.

According to Josh Novell, gardening expert and director at Polhill Garden Centre, placing pots and containers directly on the ground, particularly during storms and heavy rain can have damaging consequences. He explained that although many gardeners think rain is harmless or even good for plants, poor drainage and stagnant water can actually cause serious damage.

He said: "Even a short downpour can suffocate roots if pots sit on saturated soil.

"Waterlogged soil blocks oxygen, nutrients can't reach roots, and plants become prone to fungal diseases like root rot, powdery mildew, and leaf spot."

There is a simple solution, Mr Novell said. Simply raise your plant pots two to three inches off the ground using bricks, plant feet, or gravel so the water can drain freely and this will help keep the roots healthy.

He said: "Elevation is one of the easiest ways to protect your plants without complicated landscaping. It only takes a few minutes, but can make all the difference during heavy rainfall."

Ensuring pots have clear drainage holes is equally important to prevent water from pooling inside. Additionally, gardeners should avoid placing pots in low-lying areas where rainwater naturally gathers, as this increases the risk of waterlogging, the expert said.

Applying a light layer of mulch can protect the soil from compaction and reduce splashing onto the foliage, while stakes or supports will help prevent tall or top-heavy plants from being toppled by strong winds.

He did say that there are exceptions to the rule and some plants atually thrive under such conditions.

He said: "Some plants actually thrive in wet conditions. Aquatic plants, bog plants, and certain perennials like marsh marigolds or hostas enjoy soggy soil, so you don't need to elevate or aerate them."

Josh has also warned against other mistakes commonly made in wet weather. Covering plants with plastic or impermeable sheets, for example, may seem like a good way to protect them from rain, but it often backfires. Trapping moisture under plastic creates an environment conducive to fungal diseases. Instead, breathable covers are recommended, or if the plants are hardy enough, leaving them uncovered is often better.

Additionally, gardeners should check pots regularly to avoid water pooling and avoid fertilising just before rain, as nutrients can wash away and stress plants. After storms and rain, it's also important to inspect roots for damage and move sensitive potted plants to shelter if possible.
