Are you curious about the topic of why lilac leaves turn yellow? Read on as the editor provides a detailed explanation for you.
What Causes the Yellowing of Lilac Leaves
The most common reason for the yellowing of lilac leaves is insufficient light, as lilacs are light-loving plants. They should be placed in a sunny environment to grow.

If lilacs grow in an alkaline soil environment, their leaves are prone to yellowing.
Why Do Lilac Leaves Turn Yellow
The most common reason for the yellowing of lilac leaves is insufficient light, because lilacs are light-loving plants. They need to be placed in a sunny environment to grow. If they grow in a dark environment, the lack of sunlight prevents them from photosynthesizing, leading to yellow leaves.
1. Alkaline Soil: If lilacs grow in an alkaline soil environment, their leaves are prone to yellowing.
2. Insufficient Watering: Lilacs require a certain amount of water to grow. If the watering is insufficient, and the plants are in a water-deficient environment for an extended period, their leaves will gradually turn yellow.
3. Excessive Water and Fertilizer: If excessive water and fertilizer are provided to lilacs, their roots can easily rot. Once the roots rot, their ability to absorb water and nutrients weakens, leading to yellow leaves.
What to Do About Yellowing Lilac Leaves
1. Supplement Light Promptly: In conditions of insufficient light, it is necessary to supplement light for lilacs, allowing them to bask in the sun more, and only shading them during high-temperature periods.
2. Acidify the Soil: It is generally advisable to use a mixture of leaf mold and river sand as the potting soil for lilacs. Sulfuric acid iron can also be applied during growth to acidify the soil and supplement iron ions, improving the yellowing condition of the leaves.
3. Supplement Water: It is necessary to supplement water promptly and water regularly to keep the soil moist.
