What about the dried leaves? This treatment immediately green!

Jiuli incense is suitable for viewing all the year round, and the effect is the best when the new leaves are unfoliated in early summer. But Jiuli incense is also a green plant that needs to be maintained very much. Recently, some flower friends have encountered the problem that the leaves of Jiuli incense are dry, so what about the dry leaves of Jiuli incense? The following is to introduce the reasons for the drying up of the leaves of Jiuli incense and its treatment.

1. Normal metabolism does not need to be treated.

The high room temperature in winter disturbs the dormancy period of plants. At this time, new leaves grow normally, old leaves will gradually turn yellow, dry up and fall off, which belongs to normal appearance.

2. Lighting causes and treatment methods

Jiuli incense is a positive tree species and should be placed in a place with plenty of sunshine and good ventilation (direct light can be seen for at least five or six hours a day) in order to have luxuriant leaves and fragrant flowers. When flowering can be moved to the windowsill, full of fragrance, flowers still need to be placed in a place with sufficient sunshine, growing in the semi-shade is not as strong as the sunny place, the fragrance of the flowers is also light, too shady, the branches are soft, leaves fall, leaves are light, flowers are few or no flowers. Winter entry should also be kept in a sunny place.

3. Temperature causes and treatment methods

Jiuli incense likes to be warm, and the most suitable temperature for growth is 20: 32 ℃, which is not cold-resistant. In winter, when the lowest temperature drops to about 5 ℃, it moves into the room with low temperature (5-10 ℃) to survive the winter, and prematurely is not conducive to exercise its cold tolerance. If the room temperature is too low, it is easy to lose leaves and affect the growth of the following year. If the temperature is less than 0 ℃, the plant may freeze to death, but if the room temperature is too high, the plant can not dormant well, or even sprout indoors. When it comes out of the room, the cold wind blows, the bud retracts, and the new bud emerges again, which affects the growth of the same year. The high room temperature in winter consumes plant nutrition, which is disadvantageous to the growth and flowering of the following year. During the growth period, avoid direct sunlight, should be placed in the shade to cultivate, so as to make Jiuli fragrant flowers rich in flavor.

4. the reasons for changing the basin and the treatment methods.

If there are problems in changing the basin in winter, or in the pot of the newly bought Jiuli incense, changing the basin will hurt the root, no matter how careful you are, including the impact of the new environment on the root, water, temperature, soil and other factors will affect the root of Jiuli incense. At this time, if you are in a hurry to bask in the sun, the leaves will certainly dry up and fall, especially in the north.

5. Causes and treatment of stagnant water

Excessive water can also lead to leaf loss caused by stagnant water in the roots. Jiuli incense is drought-resistant, watering should be dry and wet, and there should be no stagnant water in the basin. In case of continuous rain, the basin should be put down or placed in a place of shelter. If too much watering, often cause rotten roots, such as leaves curling, loss of luster, this is the signal of rotten roots, to attract attention, take remedial measures as soon as possible.

First of all, the watering should be controlled and the changes should be observed. for example, after 2 or 3 days, the plant should be deducted from the basin, rinse the root soil with water, dry it, and then soak it in 1RV 5000 potassium permanganate solution for disinfection, then soak it in 1VR 2000 naphthoacetic acid rhizome solution for 8 hours before re-potting.

Watering during the growth period should not be excessive, as long as you can keep the soil slightly moist. Watering in summer high temperature season should not be too much, but water can not be accumulated in the basin (bucket). At this time, it is often necessary to spray water on the branches and leaves, which can not only play the role of cooling and humidification, but also help to make the branches and leaves green.

After entering the room in winter, you should water less, as long as you keep the basin soil moist.

6. Improper fertilization and treatment methods

Improper fertilization can also cause leaves to wither and fall. Jiuli incense is forbidden to apply thick fertilizer, raw fertilizer, fertilization should be appropriate, and grasp the types of fertilization and nutrient content, liquid fertilizer should not be too thick, must be diluted after use, otherwise it is easy to produce fertilizer damage.

Warm reminder: the application of liquid fertilizer and water should not be sprinkled on the leaves. Quick-acting fertilizer should be applied in growing season, slow-acting fertilizer should be applied in dormant period, and no fertilizer should be applied in Meiyu season and autumn.
