What is the reason why the tips of osmanthus leaves are burning?

Osmanthus tree is a kind of tree that many people like to grow. It has a beautiful shape, small and dense flowers, and can also emit a fragrance. What is the reason if the tips of the leaves of the osmanthus trees you are caring for become burnt? Let’s learn more about it below.

1. Too much light

The sweet-scented osmanthus tree is a sun-loving plant. It will only grow well if it is exposed to more sunlight and its light needs are met. However, the sweet-scented osmanthus tree has poor tolerance to strong light. If it is exposed to the scorching sun for a long time, the leaves will lose water and the leaf tips will turn yellow and dry. The osmanthus tree should be moved to a semi-shaded and ventilated place for maintenance in time, away from strong light.

2. Lack of water

Osmanthus trees have a certain demand for water. If they are not watered for a long time, the soil will dry out and the roots will not be able to absorb water, causing the leaf tips to dry and turn yellow. If the leaf tips turn yellow due to insufficient watering, you need to replenish water and moisten the soil in time.

3. Heavy soil

When osmanthus is first bought, the roots are covered with heavy red soil and planted in pots. The heavy soil has poor air permeability, which will cause root hypoxia, poor growth, and even rot, and it will not be able to supply nutrients to the leaves normally. The symptoms on the leaves at this time are burnt tips and falling leaves. At this time, you need to replace it with loose and breathable nutrient soil and replant it.

4. Waterlogging in the soil

If the osmanthus planted outdoors is rainy for a long time, or the osmanthus planted indoors is waterlogged if it is frequently watered, it will cause water accumulation in the soil, which will also lead to root hypoxia and rot, and the above-ground parts will also show symptoms of scorched tips and fallen leaves. When ground-planted osmanthus encounters continuous rain, you can dig a 10-cm-deep ditch around the plant. If potted osmanthus is watered too much, it needs to be placed in a well-ventilated and well-lit area to allow the soil moisture to evaporate as quickly as possible.

5. Poor ventilation

Long-term poor ventilation and low air quality will directly affect the respiration of osmanthus, resulting in poor growth, dry tips and burnt edges. The osmanthus flowers grown outdoors have good ventilation, so there is no need to worry; those grown indoors require more care. During daily maintenance, open the windows more often to enhance air circulation, and do not place them in a closed space.

6. Excessive fertilization

The growth of osmanthus trees requires certain nutrient support. They can only grow well if there is sufficient nutrition. However, the degree of fertilization should not be excessive and the concentration should not be too high, otherwise it will burn the roots and cause the leaf tips to turn yellow. Because too much fertilizer causes the leaf tips to turn yellow, you can water the plant appropriately to dilute the fertilizer concentration in the soil and then ventilate the plant more.

7. Temperature is too high

Osmanthus trees are not tolerant to high temperatures. High temperatures in summer will weaken their growth and cause the leaf tips to turn yellow. At this time, cooling measures should be taken. You can move the osmanthus trees to a ventilated place and spray some water around them.

8. Leaf blight

The tips of the leaves of the osmanthus tree dry up because it suffers from leaf blight. The pathogen first infects a small number of leaves on the plant, causing the parts of the leaves away from the base to become withered and yellow. Then it will gradually infect the entire leaf, causing it to completely die and fall off. If leaf blight occurs, you need to use sterilized scissors to cut off the diseased leaves of the plant, place the plant in a well-ventilated area, and spray the plant with fungicide .
