How to water ‘sensitive’ peace lily houseplants correctly to avoid root rot in winter


Peace lilies are introduced into the home for several reasons including filtering indoor air as well as adding colour into a space.

The indoor plants can also help to absorb airborne mould when cared for properly, ideal for the winter months.

According to one expert, they are “sensitive” to tap water. Natalie Devereux, product specialist at Serenata Flowers, told Express.co.uk: “Peace lies are considered easier than some other plants to look after in the winter months when there are fewer sunlight hours, despite being a tropical plant.

“They grow well in moderate to low lighting conditions. They will flower in spring if a minimum temperature of around 15C is maintained in the home throughout winter and their soil remains moist in a pot with good drainage.”

They are extremely susceptible to root rot so it is extremely important not to water them too much, especially in winter.

According to the houseplant expert, owners should not be using tap water when watering a peace lily, a “common mistake” made by Britons.

Natalie explained: “Peace lilies don’t like being overwatered, so don’t water on a schedule as it is likely they will need less in the winter than the summer when the external conditions are warmer.

“Overwatering can lead to root rot which suffocates the plant.

“Where possible, use filtered water and avoid tap water which can contain fluoride, which peace lilies are sensitive to.

“In winter, bring the water to room temperature before watering as water too cold can shock the plants.”

To correctly water a peace lily, make sure the top couple inches of soil are dry before going in with the water.

This can be done using a pencil or gently sticking your finger into the soil.

If you notice the plant is wilting, it most likely needs more water as this is a typical sign of dehydration.

However, if the leaves are drooping and turning yellow, hold back on the watering as this is a sign it has been overwatered.

Peace lilies are tropical plants so owners need to try and replicate their natural environment as much as possible.

The expert said to regularly mist the plant during the winter months to counteract the low humidity levels.
