Common Reasons Why Peace Lily Leaf Tips Turn Brown

Many of us love peace lilies (Spathiphyllum spp.) for their stunning white flowers, but even when they’re not in bloom, these houseplants are remarkably beautiful.

I’d grow peace lilies even if they didn’t bloom – those glossy, elegant green leaves are pretty irresistible.

That is, unless the foliage starts to look less than stellar, which can happen when the tips of the leaves turn brown, a fairly common occurrence.

There are a number of reasons that may cause the leaf tips to turn brown, and in this guide we will go over the most common ones.

Peace lilies are tropical plants that hail from warm, humid areas of Mexico, South America, and Southeast Asia. They do best in a location with bright, indirect light, temperatures between 60 and 85°F, and at least 50 percent humidity.

That said, they’re pretty robust and they can survive just fine if the temperatures wander out of this range or if your home’s humidity levels leave something to be desired.

However, when conditions are less than ideal, the tips of the leaves might start to turn brown. Unfortunately, once this happens, the tips won’t turn green again.

If you don’t like the appearance of the brown tips, you can either trim off the entire leaf, and wait for new foliage to replace it, or snip off just the tips.
