Soil drought: The dried leaves of the fragrant vine may be a lack of water, and the soil drought should be watered as soon as possible to replenish water.
Too much watering: it is afraid of waterlogging, watering will be more roots, easy to cause the leaves to dry out, should be drained, or dig out the plant to re-cultivate.
Improper fertilization: If thick fertilizer is applied, it will cause fertilizer damage, resulting in dry leaves, and should be rinsed with water.
Temperature is too low: If the temperature is low and easy to freeze, the temperature should be controlled to keep warm, and the temperature control in winter is above 10 ° C.
First, the soil is dry
The dry leaves of the fragrant vine are likely to be caused by soil drought, although it has a certain drought tolerance, but it can not be watered for a long time during breeding, otherwise the soil will be dry and water-scarce, prone to drought and yellowing, dead leaves, especially in the peak growing season. If this is the cause, it should be watered as soon as possible, it is best to water it thoroughly, let it absorb enough water, so that it will soon recover.
Second, water too much
Fragrant vine consumes a lot of water during growth and needs to be watered and replenished in time, but it is afraid of waterlogging. If the amount of watering can not be well controlled, too much water, the soil has water, the root system breathing will be blocked, and it will easily lead to root rot for a long time, and the leaves will turn yellow and dry. If this is the case, it needs to be dug out of the soil as soon as possible, pruned and replanted after the rotten roots.
Third, improper fertilization
Fragrant vines have a large demand for nutrients during the peak growing season, and should be reasonably fertilized and nutritionally sufficient to grow vigorously. Note that it is more sensitive to fertilizer, if you apply thick fertilizer, raw fertilizer, easy to produce fertilizer damage, so that it is easy to burn roots, once the root system is damaged can not normally to the branches and leaves to deliver nutrients, water, time will be yellow leaves, dry leaves. If this situation is caused, it is necessary to water as soon as possible, rinse off the fertilizer of the soil, and drain the fertilizer liquid. If the fertilizer is serious, it is also necessary to dig out the roots and re-cultivate.
Fourth, the temperature is too low
Fragrant vines like warm environments and have poor hardiness. After the winter, the temperature is low, if you can not control the temperature well, long-term in a low temperature environment, the fragrant vine is easy to be frostbitten, so that the leaves will be yellow, or even dry. If it is caused by low temperature, it is necessary to cut off the yellowing and dry branches and leaves as soon as possible, and also move to a warm environment, keep warm above 10 ° C, so that it can safely overwinter, and will slowly resume growth after the temperature rises in the next year.
