Gardeners warned over common mistake that could kill plants in heavy rain

As tempestuous weather sweeps across Britain, green-fingered enthusiasts are being warned about a common blunder that could spell doom for their cherished plants.

With this week poised to deliver lashing rain and fierce gales throughout the UK, countless gardening enthusiasts may unwittingly be preparing their outdoor spaces for catastrophe by committing one straightforward yet prevalent error.

According to Josh Novell, horticulture specialist and director atPolhill Garden Centre, positioning pots and planters straight onto the earth, especially amid storms and deluges, can trigger devastating results. He clarified that whilst numerous gardeners believe rainfall is beneficial or even advantageous for vegetation, inadequate drainage and standing water can genuinely inflict severe harm.

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 exists a straightforward remedy, Mr Novell revealed. Simply elevate your plant containers two to three inches above ground level using bricks, plant feet, or gravel so moisture can escape freely and this will assist in maintaining root health.

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."

Making sure pots have proper drainage holes is just as crucial to stop water from collecting at the bottom, reports the Express. What's more, gardeners ought to steer clear of positioning pots in dips where rainwater naturally accumulates, as this heightens the chance of waterlogging, the expert explained.

Putting down a thin layer of mulch can shield the soil from becoming compacted and cut down on splashing onto the leaves, whilst stakes or supports will help stop tall or heavy plants from being knocked over by fierce winds.

He did mention that there are exceptions to the rule and some plants actually flourish 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 blunders frequently made during wet spells. Wrapping plants in plastic or waterproof sheets, for instance, might appear like a smart way to shield them from rain, but it often does more harm than good.

Trapping dampness beneath plastic creates conditions perfect for fungal infections. Instead, breathable coverings are advised, or if the plants are tough enough, leaving them exposed is often preferable.

Furthermore, gardeners should examine pots frequently to prevent water from gathering and should avoid feeding just before rainfall, as nutrients can get washed away and put plants under stress. Following storms and downpours, it's also vital to check roots for harm and relocate delicate potted plants to safety where possible.
