Top Tips for a Thriving Peace Lily

A peace lily is a beautiful, classic houseplant. Its timeless foliage is perfectly complemented by white, tropical flowers. Peace lilies tend to flower in the spring but with the right indoor conditions, they can bloom more regularly.

Peace Lily Care

Light requirements

Peace lilies thrive in indirect light. They are natural lovers of shade, so their sunlight should be filtered down. Bright, direct light can cause scorching and affect the health of your plant.

Temperature and humidity

As tropical plants, peace lilies enjoy warm, humid environments. Cold temperatures can make for an unhealthy peace lily, and can eventually kill the plant. Make sure to keep it away from cold drafts and windows, especially in the winter.

You can increase the humidity around a peace lily by placing it near a humidifier, misting the leaves, or using a pebble tray. You could also place this plant in a bathroom so it enjoys the humidity from baths or showers.

Watering

Peace lilies are very vocal about when they need to be watered. You’ll be able to spot a thirsty peace lily by the sad-looking, droopy leaves. Don’t worry – as long as you don’t leave it too long, they’ll bounce right back after they’ve been watered.

To water this plant, thoroughly soak the soil and let the excess water drain from the holes in the pot. Make sure the excess drains completely before you put it back in its cover pot or on its tray. Remember to reduce watering in the colder months when the plant isn’t actively growing, so is using less water.

Potting soil

Regular houseplant mix works well for peace lilies. If you want to improve the drainage of your soil, however, you could mix in some perlite or orchid bark to improve the drainage.

Fertilisation

These plants will benefit from regular fertilisation in the spring and summer. Use a regular houseplant fertiliser, making sure to always follow the instructions on the product. Peace lilies don’t need to be fertilised in the autumn or winter.

Pruning and rotation

Remove any dead or damaged leaves with a clean cutting tool. Remember to rotate the plant every couple of weeks in the warmer months to make sure it gets equal sunlight on each side.

Repotting

Repot your peace lily in the spring or summer when it becomes rootbound. These plants are happy to remain rootbound for a while as long as it isn’t significantly suppressing growth. When you repot it, choose a pot that offers two inches of room around the root system.

Pests and diseases

Watch out for scale and mealybugs. If your plant becomes infested, remove any heavily affected leaves and treat the rest of the plant with horticultural soap. Peace lilies aren’t as susceptible to other common houseplant pests.

FAQs (Frequently Asked Questions)

Will my peace lily die back after it has flowered?

No. Your peace lily can live for many years, blooming once or twice a year. Cut off any dead flowers to keep your plant energized and healthy.

Why are the leaves of my peace lily curling?

Curling leaves (which are often also pale in colour) are usually a sign of your plant getting too much sunlight. Move your plant to a place with less direct light.
