I. Causes of Peace Lily Leaves Turning Black

Before understanding the solutions for peace lily leaves turning yellow, we first need to know why peace lily leaves turn black. Usually, if a plant has a problem, as long as it is not caused by pests or diseases, it is basically caused by improper care on our part. Qinnong.net has summarized three causes of peace lily leaves turning black here, and below we will take a specific look.

1. Watering

Improper watering is the primary cause of peace lily leaves turning black, because when we grow peace lilies at home, we usually face the problem of insufficient ventilation. If too much water is given at this time, water is very likely to accumulate in the peace lily pot, and one of the consequences is that the peace lily leaves turn black.

2. Fertilizing

Improper fertilizing can also cause peace lily leaves to turn black. This is mainly caused by applying too much fertilizer, because applying too much or too concentrated fertilizer can cause root burn.

3. Light

Although the peace lily is a tropical plant, it is fairly shade-tolerant and avoids direct sun exposure. Most of the light needed for the growth of the peace lily comes from scattered sunlight. Strong direct sunlight will cause sunburn and make the leaves turn black, so it must be avoided.

II. Solutions for Peace Lily Leaves Turning Black

Now that we know the causes of peace lily leaves turning black, the focus below is how to deal with it. If the peace lily at home has leaves turning black, we should first analyze the specific cause, and then treat it accordingly.

If it is caused by too much watering, then emergency measures must be taken: take the entire plant out of the flower pot, let it dry after handling, and then replant it. After that, attention should be paid to watering. Check the condition of the potting soil and water only after it has dried out completely, to avoid water accumulation.

For fertilizing, just apply fertilizer at a lower concentration, and do not do it too frequently. Also be careful to maintain suitable scattered light.
