How to save a peace lily with yellowing leaves in winter, and can they be pruned off?

The peace lily is a green plant that is rather sensitive to cold, so it very easily develops yellowing leaves in the severe cold of winter. So how should you save a winter peace lily with yellowing leaves? Can they be pruned off? Will it affect the growth of the peace lily?

1. Can yellowing peace lily leaves be pruned off in winter?

1. Look at the degree of yellowing of the leaves

If the yellowing is only slight and the stem connecting the leaf still feels fairly fresh to the touch, then you do not need to prune it off. You can take appropriate measures to remedy it; we will give a detailed explanation of the specific methods later.

2. The leaf has already turned completely yellow

If a peace lily leaf has already turned completely yellow and clearly feels lifeless to the touch, then at this point it is very difficult to restore it to green through remedial measures. Although winter is not the best season for pruning a peace lily, in order for the whole plant to survive the winter safely and bloom smoothly the following year, you need to cut off the yellowed leaf portion and the attached stem, so as to promote even distribution of nutrients.

2. How should you save a peace lily with yellowing leaves in winter?

Winter is the dormant growth period for the peace lily, so saving it is more difficult. Although you cannot guarantee it will completely “turn green again”, it is still worth a try so that you can witness it blooming the following spring and summer.

1. Adjust the growing temperature for the peace lily

If the peace lily is being grown outdoors, it is best to move it indoors and keep the indoor temperature between 10-28°C. This can prevent the peace lily leaves from continuing to yellow, and combined with other measures it may even help the peace lily leaves turn green again.

2. Increase the light exposure time for the peace lily

In winter, most peace lilies are in a state of lacking light, especially sunlight. So if there is sun, place the peace lily in the sun to absorb a bit more sunlight; if the weather does not cooperate, you should also supplement the light artificially.

3. Supplement the peace lily with an appropriate amount of vitamin B₁₂

You can buy 1 small bottle of vitamin B₁₂ at a pharmacy, then take 1 tablet, crush it into powder, mix it with 500 milliliters of tap water and stir evenly. Each time, pour about a few milliliters into the peace lily's soil or hydroponic bottle, applying 2-3 times per week. This can help the yellowing peace lily leaves quickly turn green again and become lush and green.

Overall, if any flower growers encounter the problem of yellowing peace lily leaves while growing peace lilies in winter, do not rush to cut off the yellowed leaves first. You can first judge whether there is still a possibility of them turning green again, and then try the above methods to alleviate the yellow leaf problem and promote the yellow leaves turning green.
