The peace lily is an extremely popular house plant, but can it get sunburn? This post explores whether or not the leaves of a peace lily will turn brown if they are exposed to too much direct sunlight. Let’s find out…
Can Peace Lilies Get Sunburn?
Yes, peace lilies can get a sunburn, but only if they are exposed to direct sunlight for extended amounts of time.
Leaving your peace lily in indirect sun for a few hours is actually good for the plant’s health, so it’s a balancing act when it comes to how much sunlight to allow.
Peace lilies that have been left in the sun for too long will usually turn brown at the tips of the leaves and along the margins. This scorching is caused by the sun’s UV rays and is called marginal burn.
As such, keep an eye on your peace lilies by checking them throughout the day. If you notice strong rays hitting your plants, then move them to a shadier location.
How to Prevent Peace Lily Sunburn?
You can prevent peace lily sunburn by keeping the plant in indirect sunlight for most of the day. This will give the peace lily enough light to photosynthesize, but not enough to scorch the leaves.
You can use curtains and blinds to protect your peace lilies from the sun. Simply pull them over when you are leaving the house, and then let them sit in indirect sunlight for at least three hours per day.
This way, you won’t have to worry if too much direct sunlight is hitting your plant because it will be protected while also getting enough light!
If you have a peace lily in a spot that gets lots of sunlight, then make sure to rotate it every two hours or so to stop one area of the plant from getting too much light.
In addition, keep an eye on the tips and margins of your peace lilies – if they start browning up, then move your plant to a shadier spot.
When Is Peace Lily Sunburn Likely To Occur?
Peace lily sunburn is common when the plant is placed in direct sunlight for long periods of time. While the leaves may not turn brown right away, it’s still important to prevent sunburns by moving your peace lilies out of the sun.
Remember that if you keep your plants in a spot with strong rays, then they’re more likely to get burned even though the damage won’t be visible until it’s too late.
Peace lily scorch can also occur when grow lights are positioned too close to the plant. This is especially true if your houseplant has recently been repotted or pruned, as it may be more sensitive to the heat from grow lights.
What Are The Signs Of Peace Lily Sunburn?
A sunburned peace lily is easy to spot because the tips of its leaves will turn brown. However, brown leaves can also be caused by other factors, so it’s important to look for additional signs of sunburn, like dry edges.
Brown leaves from fungus tend to make the leaves moist, whereas sunburn will cause brown edges that are dry to the touch.
If you are still unsure, then it’s best not to take any chances and move your plant out of direct sunlight immediately.
Can Peace Lily Plants Recover From Sunburn?
Yes, peace lilies can recover from sunburn, but it will take some time. To help your peace lily heal faster and prevent further damage in the meantime, you should increase humidity around its leaves.
In addition to increasing humidity levels, you should stop exposing the plant to sunlight for at least a week after its leaves have recovered. You can keep your plant in full shade for a few days, and then slowly return the plant to partial light after it has recovered.
Will Burnt Peace Lily Leaves Turn Green Again?
No, it is unlikely for peace lily leaves to return back to their original green color. Instead, the brown edges will remain burned for good even after you move your plant out of direct sunlight and increase humidity around it.
However, if the tips only turned partially brown (or were scorched by grow lights), then they may turn green again over time once the damage has been repaired.
Will Sunburn Kill My Peace Lilies?
No, sunburn does not kill peace lilies. However, it is important to prevent the leaves of your plant from turning brown by reducing direct sunlight exposure and increasing humidity around its foliage.
While some new growth may be discolored if you place your houseplant in an area with strong rays for several weeks or more, most plants can recover within a few months.
In conclusion, peace lilies are sensitive to changes in sunlight. Make sure that your peace lilies are not placed in direct sunlight for more than a few hours per day and rotate them every two or so hours so all sides get equal access to the sun.
If you see brown tips, then move them out of direct rays immediately. This can help prevent further damage to the plant and will kickstart the recovery process.
