What's wrong with the new leaves of murraya murraya?

Murraya murraya is mostly used as a bonsai material, with lush foliage and pleasant flowers. Although the maintenance is better, we should pay attention to some details when maintaining. The growth temperature of murraya murraya is 18-28 degrees, which belongs to plants that like warmth and sunshine, but they are afraid of humidity and sun exposure. Pot soil should be dried and watered thoroughly. It should be placed in a well-lit place at ordinary times, and properly shaded in summer and high temperature seasons.

The new leaves of Murraya murraya appear curly, probably because of lack of water. Murraya murraya has a certain drought tolerance, but if the soil is hardened or not watered for a long time, the new leaves will become curly and fall off. As long as the air is wet and the pot soil is thoroughly watered, the curled leaves will naturally spread out, but the pot soil should not be too wet, and then it should be thoroughly watered when it is dry. The basin soil should be loose, breathable and permeable, and the basin soil of Murraya murraya is mixed with humus soil, garden soil and river sand in a ratio of 5:3:2.

Although Murraya enjoys sunshine and warmth, the temperature in some places in the south has suddenly risen to 30 degrees in recent days. Under the exposure of strong light and scorching sun, new leaves will also curl. When the temperature is high, it is necessary to properly shade the sun, cool down and ventilate, especially pay attention to the sudden rise of the temperature. If the new leaves are only wrinkled and not curled, it may be a sign of lack of fertilizer. It is necessary to properly apply more organic fertilizer, which has a stronger scent of murraya.

1. What happened to murraya murraya leaves?

The leaf curl of Murraya murraya is mostly leaf curl moth and aphid, which harms young leaves, makes them curl and die, or shortens the growing point, affecting the normal growth of leaves.

Control method: During the growth period of young leaves, it is possible to spray once the purified water solution, the water solution of Daxiong 1500 times and the water solution of Anlubao 1500 times to control and kill the larvae.

Second, what is the leaf loss of murraya murraya?

1. temperature reason: murraya murraya likes warmth, and the optimum growth temperature is 20~32℃, so it is not cold-resistant. When the lowest temperature drops to about 5℃ in winter, indoor activities at low temperature (5~ 10℃) are not conducive to exercising its cold resistance. If the room temperature is too low, the leaves will fall off easily, which will affect the growth of the next year. If the room temperature is below 0℃, plants may freeze to death. If the room temperature is too high, plants will not sleep well and even sprout indoors. When cold air blows out of the room, the buds will shrink, and when new buds germinate again, it will affect the growth of that year. The room temperature is too high in winter, which consumes plant nutrition and is not conducive to growth and flowering in the following year. Avoid direct sunlight during the growth period and cultivate in a cool place, so that the flowers of Murraya murraya can be rich in fragrance.

2. Reasons for changing pots: If you change pots of murraya murraya in winter, or the pots of murraya murraya just bought have problems, the roots will be damaged. No matter how careful you are, including the influence of the new environment on the roots, water, temperature, soil and other factors will affect the roots of Murraya murraya. If you are in a hurry to bask in the sun at this time, you will definitely lose your leaves, especially in the north.

3, normal metabolism: the room temperature is too high in winter, disrupting the dormancy period of plants. At this time, new leaves grow normally, and new and old leaves appear, and the old leaves will slowly turn yellow and fall off, which is normal.

4, lighting reasons: Murraya murraya is a positive tree species, should be placed in a sunny and ventilated place (at least five or six hours of direct light every day), so that the leaves are lush and fragrant. When the flowers bloom, you can move to the windowsill, and the house is full of fragrance. After the flowers wither, they still need to be placed in sunny places. The growth in the semi-shade is not as strong as that in the sun, and the fragrance of flowers is also weak. If it is shaded too much, the branches will be soft, the leaves will fall off, and the leaves will be very light, with little or no flowering. In winter, indoors should also be placed in sunny places.

5. Improper fertilization: Improper fertilization can also lead to defoliation. It is forbidden to apply coarse fertilizer and raw fertilizer to Murraya murraya, and it is necessary to apply appropriate fertilizer to master the types and nutrient content of fertilization. Liquid fertilizer should not be too thick, so it must be diluted before use, otherwise it will easily cause fertilizer damage.

6. Causes of water accumulation: Too much water will also cause water accumulation in the roots and cause the leaves to fall off. Murraya murraya is drought-tolerant, so it should be watered wet and dry, and there should be no water in the basin. In case of continuous rain, the flowerpot should be put down or placed in a shelter. If you water too much, it will often cause rotten roots, such as leaves curling and losing luster. This is a signal of rotten roots, which should be taken seriously and remedial measures should be taken as soon as possible. First of all, we should control watering and observe its changes. If it takes 2 ~ 3 days, it still doesn't get better, but it gets worse. Then, the plants should be taken out of the pot, washed with water to remove the soil from the roots, dried, soaked in potassium permanganate solution of 1:5000 for disinfection, soaked in rooting solution of 1:2000 for 8 hours, and then put into the pot again.

It is not advisable to water too much during the growing period, as long as the soil remains slightly wet. It is not advisable to water too much in hot summer, but there should be no water in the basin (barrel). At this time, it is necessary to spray water on the branches and leaves frequently, which can not only cool and humidify, but also help to make the branches and leaves oily green. Water less after entering the house in winter, as long as the soil is kept moist.
