Why are the osmanthus leaves turning yellow and the tips withering?

The osmanthus tree is loved for its elegant shape, small and dense flowers, and charming fragrance. Its leaves are green and shiny, making it suitable for potted or ground planting and has great ornamental value. However, in the process of caring for osmanthus trees, the tips of the leaves often turn yellow and dry. Let’s learn and understand why the leaves of osmanthus turn yellow and the tips wither.

1. Lighting issues

Osmanthus trees are sun-loving plants and require plenty of sunlight to maintain good growth and the fragrance of their flowers. However, it has poor tolerance to strong light, and prolonged exposure to the sun may cause the leaf tips to turn yellow and dry.

Solution: Move the osmanthus tree to a semi-shaded location, away from direct sunlight, while ensuring good ventilation to help the leaves recover.

2. Moisture management

Osmanthus trees need an appropriate amount of water. Excessively dry soil will cause the roots to be unable to absorb enough water, which will cause the leaf tips to dry out.

Solution: Replenish water in time and moisten the soil. Usually water the plant according to the dryness of the soil. After the soil surface turns white, water it appropriately to avoid water accumulation.

3. Fertilization issues

Osmanthus trees need nutrients to grow, but excessive fertilization or high concentration of fertilizer will cause root burn, which will in turn cause the leaf tips to turn yellow.

Solution: If the problem is caused by over-fertilization, water appropriately to dilute the fertilizer concentration in the soil, and increase ventilation to help the plant recover.

4. Temperature issues

Osmanthus trees are not very tolerant to high temperatures. High temperatures in summer may cause the plant to grow weaker and the leaf tips to turn yellow.

Solution: Take cooling measures, such as moving the osmanthus tree to a ventilated place and spraying water around the plant to control the temperature within a suitable range.

In short, when facing the problem of yellowing and drying of the tips of osmanthus leaves, the key is to accurately identify the cause and take corresponding measures. With proper light, water, fertilizer and temperature management, the osmanthus tree can recover its health and its leaves will regain their bright color.
