Osmunda japonica cultivation is relatively simple and has strong environmental adaptability. However, if the long-term maintenance and management methods of Lagerstroemia indica are improper, it will also make the leaves dry and yellow. Let's take a look at the reasons and solutions with Uncle Gardener.

1, drought and water shortage

Lagerstroemia indica likes to grow in humid environment, and the position with high air humidity will grow better. If you don't water for a long time and the air is dry, the tip of the blade is easy to turn yellow and dry.

Solution: If it is caused by drought and water shortage, it needs to be watered in time. If it is in summer, it is necessary to spray water on plants or the surrounding ground to improve the humidity of the air, so as to avoid the phenomenon of dry tip of its leaves due to lack of water.

2. Burning roots with chemical fertilizer

Osmunda japonica has a great demand for fertilizer, but it can't be applied too much at ordinary times. If the fertilizer concentration is too high or the dosage is too large, it will burn its roots and cause the leaves to turn yellow.

Solution: If the root is burned by fertilizer, it is suggested to directly replace it with new pot soil to avoid further damage from fertilizer. Just prepare a new pot of soil for it, water it once after putting it in the pot, and put it in the shade to slow down the seedlings.

3. Strong light irradiation

If it is a small Lagerstroemia indica seedling, it is not resistant to strong light, especially if it is maintained in the scorching sun for a long time in summer, it is easy to sunburn its leaves, resulting in damage to its tip.

Solution: Take sun-shading measures in time, and build a awning with a black sun-shading net to reduce the illumination time or intensity. If it is potted, it can be moved directly to a cool place indoors for maintenance.

4. Powdery mildew

Powdery mildew is a common disease of Lagerstroemia indica, which mainly harms young leaves and leaves, and the diseased leaves will turn yellow.

Solution: To improve the growing environment of plants, move them to outdoor places with good lighting and ventilation, and spray carbendazim solution or triadimefon on plants.
