The reason for this situationFirst of all, we must first clarify what the cause is. As we know, the leaves of the seven-leaf lily should be very smooth and very clean. In fact, the oil secretion of its leaves is an instinctive manifestation caused by insect pests. The common pests encountered by seven-leaf lilies are scale insects and aphids. These two insects absorb nutrients from the leaves to survive. At the same time, they secrete an oil-like substance, which makes us mistakenly believe that the seven-leaf lily itself produces oil. In fact, this oil-like substance will seriously endanger the health of the leaves. In worse cases, it may even cause them to wither. Solution1. In the daily maintenance and management of this flower, you must pay special attention to observation. When you first find insect pests, you must kill them. The large-scale reproduction of insect pests will cause the situation to worsen. 2. Leaves that have been attacked by pests must be removed in time, otherwise the pests will be transmitted to each other and affect the growth of other leaves. 3. Make sure that the seven-leaf lily gets plenty of sunlight every day, but of course avoid exposure to the scorching sun. Sunlight is also extremely lethal to insect pests and can help alleviate the oil production problem. 4. When the oil production of seven-leaf vine is particularly serious, pesticides must be used to control insects. It is generally recommended to use 1000 times diluted 40% oxydemeton-methyl or 1500 times diluted 50% malathion for overall medication. Generally, it needs to be sprayed once a week, a total of three times, and basically the oil production of the leaves will improve. Now that the big problem of oil secretion from the leaves of seven-leaf lily has been solved, are you flower lovers more confident in growing seven-leaf lily? If you have friends who like it, hurry up and grow one! |
