Peace lilies will require special care during winter since they are native to tropical climates and thrive in warm and humid conditions.

If not properly cared for in winter, peace lilies can suffer from wilting leaves and discolouration and may even die.

Houseplant experts at Simplify Plants have warned that peace lilies don't struggle in temperatures above seven degrees and remain healthy. However, if it falls below four to seven degrees, “peace lilies start showing problems”.

They explained: “The care routine of the peace lily during the summer and the springtime is different and should be discontinued in the winter season. You might be unintentionally killing your peace lily by doing the same things in winter.”

The experts have outlined the “correct requirements” all peace lilies need in winter to ensure positive growth.

Light

The pros stated that light is a “vital requirement” for these plants as “they depend on light for their survival”. The lack of light in winter can lead the plant into dormancy.

The experts suggest finding a spot in your home with the most light during winter and moving your peace lily there. They even say the plant can be kept under direct sunlight for a few hours daily during the colder months.

However, they urged households to “never” keep the plant near a window during winter as this could expose it to cold drafts or low temperatures, which can be “very detrimental” to the peace lily and “will not guarantee the growth of blooms”.

Artificial lights can provide extra light to the peace lily during winter, but this may not be necessary if the plant is healthy.

Water 

Water is a “fundamental requirement” for all houseplants, but the needs change with the seasons. When the plant gets less light in winter, the soil takes longer to dry out.

The plant experts advise reducing watering of the peace lily during winter and waiting for the soil to dry out. If you're using artificial light and providing extra heat to your peace lily, the soil will dry out faster, and the plant will need more water.

They also warn against using cold water, which can shock the plant. For best results, use room-temperature water.

Temperature

Simplify Plants have warned that peace lilies "do not prefer cold temperatures and often die if kept cold for an extended period". The temperature between seven and 12 degrees is tolerable for the plant and should be maintained if you want it to "survive the winter".

They’ve flagged that temperatures below seven degrees are “dangerous” for peace lilies, and such chilly conditions could potentially be “life-threatening for the plant.”

They suggest using a fireplace or any heating source in the room to keep your peace lily cosy, but caution is against placing the plant too close to heat to avoid damage. Maintaining a few feet of distance is recommended.
