The Peace Lily is a beautiful houseplant that is easy to care for. It is relatively low maintenance, only needing to be watered about once a week. They are also very effective at cleaning the air of harmful toxins and boosting humidity levels. However, growing this plant may sometimes be challenging.
One of the significant challenges that come with growing peace lily is sticky leaves. In this article, we will tell you why this happens to your peace lily and what you can do about it.

Why Is My Peace Lily Sticky?
Peace lily becomes sticky because of honeydew. This substance accumulates on the leaves when scale insects get attracted to the plant. In fact, when scale insects attach themselves to the leaves of peace lilies, they start sucking out the sap and excreting honeydew. As a result, the leaves become sticky.
Scale insects are tiny insects that feed on the sap of plants. They are attracted to peace lilies by the smell of the sap.
You can detect scale insects on peace lilies by looking for small, hard bumps on the stems or leaves. These bumps are actually the insects themselves.
If you don’t fight scale insects at an early stage, the consequences can be disastrous. The insects will feed on the plant’s sap, causing the plant to become weak and stunted. The plant may also produce fewer flowers and leaves. In severe cases, the plant may die.
