Lily is quite a simple plant. This beautiful flower is grown in every garden and greenhouse. But there are some care features that you need to know so that this beauty honors the gardener with her flowering. One of these features is the soil and watering. The second is the prevention of fungal and viral diseases, as well as the prevention of pests. There are several reasons why lily leaves turn yellow. Determining the cause of disturbances quickly and correctly will help to avoid the further spread of dangerous diseases of these charming plants.
Iron deficiency, or chlorosis. Chlorosis is especially noticeable on young leaves. A seemingly he althy plant every day acquires a bright grassy yellow color of the leaves, and the gardener wonders in bewilderment: "Why?" The leaves of the lily turn yellow more and more, but the veins of the leaf retain their he althy green color. Such a deviation occurs in plants that are in calcareous soil with high acidity and with excessive waterlogging of the soil. It is also a violationobserved at high soil temperatures. Among the lilies, there are varieties that are especially prone to yellowing of the leaves due to a lack of iron. To solve this problem, during plant growth, root or foliar fertilizing with iron preparations is carried out.
Late blight, or soft rot. Plant growth is slow. The lower leaves begin to turn yellow first, gradually the yellowness spreads upwards. Most often, rot forms on the stem in an undeveloped top. The leaves turn yellow, the top begins to turn black, and the aerial part of the plant bends. Frequent rains contribute to the development of the disease.
Fusariosis. Expressed in brown spots on the stems. Leaves turn yellow prematurely and fall off. The scales that make up the bulb also become stained and rot. After a while, the whole plant dies completely. To avoid this disease, you need to choose he althy bulbs for planting.
Leaf nematode. Another likely reason why lilies turn yellow is pests. Plants develop slowly and do not bloom. The leaves take on a round yellow-brown color and eventually dry out and fall off. Lesions can be seen at first on only one side of the leaf. Nematodes live between the scales of the bulbs and, under favorable conditions, are selected. The fight against these pests consists in processing the bulbs just before planting, processing the growing plants and removing weeds from the beds.
Another reason why lily leaves turn yellow,is a deficiency or excess of nitrogen. In the case of an excess of nitrogen-containing fertilizers, spots appear on the leaves of lilies in spring, which turn brown, and then the entire leaf turns yellow and dies. Usually in this case, the bulb itself is badly damaged by spots. It is better to throw away such plants, as this is a functional violation. Another possible reason why lily leaves turn yellow may be a lack of nitrogen. Plants are pale, yellowish, poorly growing. The situation can be corrected by fertilizing containing the right dose of nitrogen.
