Why do honeysuckle leaves drop? The latest analysis is here
Honeysuckle is also called Japanese honeysuckle, and it is widely used in our daily lives, while the area planted with it is also spread across the whole country. Previously, many honeysuckle growers consulted online, saying that the honeysuckle they planted showed abnormal leaf drop. Why is this? Is the honeysuckle sick, or what is causing it? The editor specifically analyzed this issue and organized the information. If you need it, you can carefully read the content below.
1. Unsuitable soil
When leaf drop occurs in honeysuckle cultivation, the first thing we should consider is the problem of the planting soil. Although honeysuckle has strong adaptability, that does not mean all soils are suitable for growing honeysuckle. If the planting soil is unsuitable, it will also cause honeysuckle leaf drop. Secondly, there may be no problem with the planting site itself, but later work such as loosening the soil and earthing up was not done properly, causing the soil structure to change, which will also cause honeysuckle leaf drop. If it is caused by a soil problem, then we need to change the planting site or disinfect and manage the soil before planting.
2. Improper water and fertilizer management
Improper water and fertilizer management is mainly shown in four aspects: water yellowing, drought yellowing, fertilizer yellowing, and starvation yellowing. Water yellowing is caused by overwatering; drought yellowing is caused by a lack of water or failure to water in time when watering is needed; fertilizer yellowing is caused by applying too much fertilizer, too frequently, too heavily, or using the wrong type of fertilizer; starvation yellowing is due to insufficient nutrients without timely topdressing, leading to poor growth and development and other problems. So what we need to do is apply fertilizer scientifically according to the nutrient requirements of honeysuckle, and reasonably use nitrogen fertilizer, phosphorus fertilizer, potassium fertilizer, micronutrient fertilizer, foliar fertilizer, as well as organic fertilizer and farmyard manure. After each fertilization, it is best to water once to dilute the concentration and promote nutrient absorption. Actively water during hot and dry seasons, and drain in time during the rainy season.
3. Inadequate pest and disease control
Of course, the abnormal leaf drop of honeysuckle in Xinxiang may also be caused by pests and diseases. The diseases that cause honeysuckle leaf drop are generally powdery mildew, brown spot disease, and root rot. Powdery mildew and brown spot disease occur mostly around August each year, so what we need to do is strengthen field management, reasonably adjust branches and leaves, and maintain air circulation between plants. Secondly, chemical prevention can be carried out in June, using Syngenta's Aimiao 3000-fold solution for prevention, and after the disease occurs, triadimefon can be used for control. For root rot, a fungicide mixed with an insecticide can be used for root drenching control. The insect pests that cause honeysuckle leaf drop are generally underground pests, such as white grubs and cutworms, so we can use methyl isofenphos granules for poisoning and killing them.
4. Light conditions
Abnormal leaf drop in honeysuckle may also be caused by light. Honeysuckle is a light-loving plant with a relatively large demand for light. If there is insufficient light, honeysuckle cannot carry out photosynthesis normally, so leaf drop will also occur. When this situation occurs, we need to strengthen the light for honeysuckle, reasonably adjust the sunlight at the planting site so that honeysuckle can carry out photosynthesis normally, or change the planting site to promote the growth of honeysuckle plants.
Generally, when abnormal leaf drop occurs in honeysuckle, it is basically caused by these reasons. Of course, special situations are not ruled out. If you encounter abnormal leaf drop and cannot solve it using the above methods, you can also consult us.
