Peace lilies are beautiful plants that are known for their large, white flowers. However, they can sometimes be riddled with small holes! But what are these holes? In this article, we discuss why your peace lily has holes in the leaves. Let’s go…
Why Are There Holes in my Peace Lily Leaves?
The main reason why your peace lily has holes in the leaves is that there is liriomyza melanogaster present in the soil. These are insects, known as leaf-mining flies, that tunnel through the leaves and cause damage to the host plant.
One of the unpleasant side effects that this pest causes is holes in leaves. Since it enjoys coming out at night and hiding during the day, it can be hard to spot these pests on your peace lilies until you look closely and see a hole or two in some of the leaves.
You may also have a problem with leaf spot disease. This is a fungus that starts as small spots and then escalates into small holes in the leaves.
How To Prevent Holes in Peace Lily Leaves?
You can apply neem oil spray (Amazon link) to your peace lily to prevent leaf miners from eating into the leaves. Pests that love to feed on your peace lily may have transferred over to other plants in the environment, which could damage them without careful attention. That’s why I use neem oil on all houseplants when I notice insects on just one of them.
In case peace lily is harboring leaf spot disease, you should treat it with an appropriate solution as soon as possible. Improve the overall health of your plant by removing diseased leaves and disposing of them in a safe, out-of-the-way place. The above neem oil can also be used as a fungicide, so this should also remove any fungal infections.
How To Keep the Plant Healthy?
Location: Place your peace lily in bright, indirect light.
Temperature and humidity: You should keep your peace lily at a temperature of about 68°F. Humidity should be around 60% for optimum growth.
Soil: Peace lily plants need soil that is well-draining and less acidic.
Watering: Keep the soil moist but not wet to avoid root rot and overwatering. The plant should be watered once a week or when it drains away from the pot’s bottom hole.
Fertilizing: Feed your peace lily with an all-purpose fertilizer at half strength every month in spring.
Cleaning: Peace lily plants can get dusty and icky, so feel free to clean them off with a damp cloth every few weeks.
To conclude, the holes on your peace lilies are most likely from pests or leaf spot disease, with insects being the most likely cause.
Neem oil spray (Amazon link) is always a good option for insect control if they are in my house plants.
