As colder mornings approach, it’s time to prepare our gardens for the chill. Brits are now being encouraged to give their plants a little extra care, including offering them a surprising treat – a cup of tea.
This unusual gardening tip comes from plant expert Millie Durback, the brand manager at Prestige Flowers. She explains that tea, particularly caffeine-free varieties like chamomile or rooibos, can be a gardener’s “secret weapon” against the cold. “Tea contains tannins that strengthen plant cell walls, making them more resistant to frost,” Millie says. “It’s a natural defense against freezing temperatures that many gardeners overlook.”
However, she advises using only unsweetened, dairy-free tea to avoid any negative effects on the soil. In addition to providing protection, tea leaves can also be beneficial for plant growth, as they are rich in nitrogen. Used tea bags can even serve as an excellent fertilizer thanks to their tannic acid content.
Millie also suggests protecting plants from snow damage by covering them. “Think of it as tucking your plants in for a winter nap,” she says. Using burlap or landscape fabric can create a barrier that insulates plants, shielding them from harsh winds and helping retain warmth from the ground.
For potted plants, Millie recommends raising them off the ground to prevent freezing. Placing them on bricks helps keep them away from frozen soil, reducing the risk of root damage. Adding extra protection by wrapping pots in bubble wrap or foam insulation is also a good idea.
Finally, for succulent plants, which store water in their leaves, Millie advises bringing them indoors during the colder months. Their excess moisture makes them particularly vulnerable to freezing temperatures.
