As we approach the end of winter, March brings with it the promise of warmer, more milder days – and homeowners need to be aware.

A warning has been issued to UK households who have houseplants in their homes in March. As we approach the end of winter, March brings with it the promise of warmer, more milder days – and homeowners need to be aware.

The change in circumstances and conditions could see houseplants massively impacted. Gardeners’ World explained: “All house plants need water to keep them alive, but how much depends on their country of origin and the environment they evolved in. For example, a plant native to the jungles of South America will need more water than a cactus from the Mexican desert.

“Knowing how much water to give your plants is key to their survival.” On h ow to save wilted house plants, they added: “ It pays to know the signs of under- or over-watered plants. Plants will ‘tell you’ if you’re not doing it right.

“If your plant is looking sickly, first check the compost. If it’s dry, immerse the plant’s pot in a bucket of water and hold it down – air should bubble up. Leave it until the compost is soaked through and the plant shows signs of perking up. Allow the water to drain before returning it to where it was growing.

“Wilted yellow leaves can be a sign of overwatering. If the compost is damp, let it dry out before you next water.” On its own website, RHS gardening advisors warned not to overwater, explaining: “With lower light levels and lower temperatures, plants will be growing less – so they will need less water. In particular, watch out for plants sitting in water. If you’re using pot covers (i.e. decorative clay or metal pots that hide the plastic pots the plants are growing in), revisit your plants 10 minutes after watering and tip away any excess.”

Winter presents a double set of challenges for houseplants. Being too near radiators or fires can crisp delicate leaves and being left in the cold on windowsills and behind curtains can damage some plants. The RHS says, if you can, place your houseplants away from any extremes of temperature and avoid draughts, too.
