If you say that any kind of seed ball can be sown in four seasons, then in spring you think that Lily is a kind of bulbous plant that can be sown in four seasons, because lily has very heat-resistant varieties and cold resistant varieties. As long as you choose heat-resistant varieties in summer, you can choose cold resistant varieties when it's cold, and you can sow almost at any time. Many flower friends will choose to buy lily varieties The ball, but Lily's seed ball grows after home, but at last does not bloom what is the reason? Next, let's share with our flower friends the two diseases that cause lilies not to bloom, as well as the prevention and treatment of these two diseases.
One of the diseases that cause Lily not to bloom: grey mould of Lily
Grey mould of lily is a common disease in lily. The main symptom is that the leaves produce light brown water spots, and the spots will spread downward, which will lead to the deformity of lily flower bud and withered petals. The main cause of grey mould is excessive humidity of soil and plant. Lily is a kind of bulbous plant that is relatively resistant to moisture, but when flower friends mix soil for Lily, they must ensure that Lily mix soil and drain well.
Flower friends potted lilies, when the humidity is relatively high, do not spray water on the lilies, too much water spray can easily lead to the lily grey mold. The rain in dry areas has little impact on the lilies, but it must be ventilated after the rain, and the well ventilated area is not easy to allow the water to accumulate on the plants, so there will be no grey mold.
It was found that Lily had grey mould disease. Flower friends should pull out the diseased plants to avoid infecting other plants. In the early stage of Lily grey mould disease, flower friends could use 1000-1500 times liquid of 50% hygroscopic powder of isocarbazide, spray once every 7-10 days, twice in a row, which had a better effect on mild grey mould disease.
Lily virus disease: the second disease that causes Lily not to blossom
Virus disease is divided into Lily mosaic disease and Lily leafroll disease. The symptoms of Lily mosaic disease are mainly light green or dark green on lily leaf surface, mottled color, and the edge of its leaf becomes twisted outwards. After this symptom, lily plants will become very small, unable to form flower buds or cannot be opened due to deformation of flower buds.
The main symptom of lily leaf curling disease is that the leaves of the plants are twisted, the leaves become very thick and deformed, and the stems of lilies are abnormally enlarged and bent. Lily plants suffering from leaf curling disease are also very small, which can not form flower buds or the flower buds are deformed and do not open. The main causes of lily virus disease are: too high density of Lily planting or very serious insect damage, too high soil temperature, too low humidity, and insufficient soil nutrition.
When you plant lilies, you should plant them in loose and airy acid soil. You may plant many kinds of bulbs in one basin, but it is suggested that you should plant three kinds of bulbs in one gallon basin. Such density generally will not cause excessive density of lilies and cause virus diseases. Lilies are relatively wet bulbs, which can't be treated like hyacinth If lily virus disease is found, flower friends should also pay attention to whether lily has spider and other pests.
The prevention of lily virus disease is more important than the treatment. Before Lily blossoms, flower friends can often spray potassium dihydrogen phosphate solution or zinc sulfate solution on Lily leaves to improve the anti-virus ability of lily. In the early stage of the disease, 500 times of copper sulfate wettable powder can be used to spray lily plants with virus disease. If it is found that there is a lily with virus disease in the same basin, but there is no virus disease in other lilies in the basin, the flower friends must clean up the infected plant to prevent it from infecting other plants.
