Many households are preparing to clear away decorations and dispose of their Christmas tree.
But one gardening expert says the tree’s usefulness does not end when the lights come down.
Instead, it could become an unexpected asset during the coldest weeks of winter.
A second life
Garden expert David Denyer says real Christmas trees can be repurposed in January as natural mulch.
Speaking on behalf of flower delivery specialists Eflorist, he said many people underestimate the value of a tree once it leaves the living room.
“Many people don’t realise just how valuable a Christmas tree becomes once the decorations come down,” Denyer said.
“When broken down into mulch, your Christmas tree can be endlessly useful for your garden. Once mulched, the needles and branches of a Christmas tree can help your garden soil retain moisture, suppress any weeds, and gradually enrich the soil as they decompose.”
Winter protection
According to Denyer, timing is crucial. January and February are when plants are most vulnerable to frost and harsh weather.
“A layer of mulch during January or February will also help protect any plant roots from frost, giving plants extra protection during the coldest weeks of winter while preparing the garden for early spring growth,” he said.
He added that mulch helps reduce soil erosion during wet spells and preserves moisture during dry, cold winds.
Which plants benefit
Christmas tree needles are naturally acidic, making them particularly suitable for certain plants.
“Christmas tree needles are naturally acidic, so you should use this mulch on acid-loving plants such as blueberries, azaleas, camellias, and rhododendrons,” Denyer explained.
However, he stressed that gardeners should not worry about long-term soil damage.
“As pine needles break down, they quickly neutralise, meaning you can safely use them around most shrubs, perennials, and fruit bushes.”
He also noted that strawberries can benefit, as the sharp needles may help deter slugs and snails.
Simple methods
For those with access to a shredder, Denyer recommends breaking the tree into small pieces for faster decomposition.
Without one, he suggests leaving the tree outdoors to dry so the needles fall naturally and can be collected.
Leftover branches can be composted or stacked to create shelters for wildlife.
“Any leftover branches can become a real winter lifeline for wildlife,” he said, adding that such piles provide refuge for insects, frogs and hedgehogs.
