Why do lilies turn yellow leaves

Why do lilies turn yellow leaves

Lily is a perennial herbaceous crop from the lily family. We can say right away that any unhealthy condition of the plant, and even more the yellowing of the foliage, is a consequence of improper care of the crop. Based on this, you first need to provide comfortable conditions and conscientious plant care. You also need to take care of preventive measures in the fight against various diseases and insect pests. So why does a lily's leaves turn yellow?

The first reason is too low air humidity and insufficient watering.

Lily came to us from tropical, humid forests. Therefore, during the summer heat, it may be too hot, especially if it grows in close proximity. Because of this, leaf plates can turn yellow and even dry out. To avoid such consequences, you need to plant plants in a semi-shady area, while observing the distance between the beds and holes. You also need to adjust the watering mode. The soil in which lilies grow should not dry out excessively. But it is also impossible to overfeed the plants with water, this can cause rotting of the root system, which will also cause yellowing of the leaf plates.

The second reason is a lack or an excess of fertilizing.

If the lily lacks trace elements, macronutrients, nutrients, then it will show this by the changed color of the leaf plates, namely the leaves of the lily will turn yellow.

Lily leaves turn yellow if there are not enough iron elements

If the lily lacks iron, then the work on the formation of chlorophyll will be disrupted, and he, in turn, is necessary for the normal functioning of photosynthesis. This is especially typical for consideration, this is manifested on young specimens, because they will only become more yellow from day to day, but the veins will still remain bright green in color. If this happens, then you need to feed the lily. For this you will need: 1) Two teaspoons - citric acid; 2) Eight grams - ferrous sulfate; 3) Three liters - clean, settled, soft water at room temperature. All this must be thoroughly mixed. It can be used both in spraying and in watering the soil in which the flower grows.

If there is a shortage or excess of nitrogenous elements

If the lily lacks nitrogenous elements, then its color becomes more faded, it can turn yellow, slow down growth and development. In this case, you need to choose a fertilizer in which nitrogenous elements have an advantage. When using this fertilizer, it is very important not to overdo it. If the culture is overfed with nitrogenous elements, then the leaf plates will be covered with brown spots, which will turn yellow over time, and the foliage itself will simply disappear. The bulb of the plant will also suffer. Experienced growers say that such a plant can no longer be saved. The only thing you can do is just dig it out of the hole.

Diseases and pests as the reason why lily leaves turn yellow

Lily leaves turn yellow: the reason and what to do?

If the lily is attacked by various insect pests, as well as bacterial viruses, fungal infections, then it will naturally react to this by changing the color of its leaf plates.

Why do lily leaves turn yellow: bacterial rot

Many cultures are affected by this disease. This disease manifests itself in the fact that the foliage of the plant begins to turn yellow, and then dies. It may appear due to the fact that the bulb of the plant is damaged, or the soil is excessively waterlogged. You can only fight with preventive measures. Before planting, the plant bulbs must be soaked in a manganese solution. When the first shoots appear, the plant must be etched with fungicidal preparations. But if you find a disease when the plant has already entered the flowering period, then the bush will have to be destroyed, because bacterial rot cannot be treated.

Lily leaves turn yellow: the reason is rust

If yellow, bright orange, or brown spots appear on your lily, then you need to take a close look at the presence of bright orange spores of the fungus. Outwardly, they resemble small, fluffy pillows. If these spots have a convex shape, then this means that the plant is sick with rust. In this case, you must immediately remove all infected parts of the culture. And the plant itself must be treated with one percent Bordeaux liquid. Re-planting in the place where the infected plants grew is possible only after at least three years.

Lily leaves turn yellow: blue mold, or phytium

This disease can cause rotting of the root system of the plant. The bulb will become covered with brown specks, and at the same time, the upper part of the foliage will begin to turn yellow, and the stalk will gradually dry out, and over time it will completely die off. All diseased parts of the culture must be destroyed immediately. For prevention purposes, you can disinfect the soil before planting with a solution of colloidal sulfur with a concentration of four tenths of a percent. And the bulbs themselves can be soaked in a solution of foundationol with a concentration of two tenths of a percent, for about thirty minutes.

Fusarium as the reason why the leaves of the lily turn yellow

This disease, first of all, affects the bulb of the plant. The bulb becomes brown, and then completely disintegrates into several parts. Based on this, saving the plant is not possible. In addition, at the earliest stage of the development of the disease, its appearance can be seen only on the bulb, but it is located in the depths of the soil. After a certain amount of time, the shoots of the culture begin to turn yellow. And if the lily grows in warm conditions with high humidity, then the yellow leaf plates will gradually begin to dry out. You can only fight with preventive measures. Before planting, the plant bulb must be soaked in a foundation solution, and the planting soil-mixture must be disinfected.

Botrytis, or gray rot as the reason that the leaves of the lily turn yellow

This is a fungal infection. When it appears, the plant will be covered with dark orange specks. Also, spots of a watery format can be seen on the inflorescences of the bush. It is not possible to withdraw this disease entirely. For in the summer heat and with an increased percentage of air humidity, the fungus will begin to actively develop again. All affected leaf plates and stems must be destroyed urgently. And at the beginning of the autumn period, it is necessary to dig up the bulbs in order to then process them with a special fungicidal preparation called maxim. You also need to transplant them to a new location in the garden. For prophylaxis, in the spring, it is necessary to treat crops with a phytosporin solution.You also need to perform repeated phytosporin procedures, each time under conditions of high humidity.

Lily leaves turn yellow: the reason is nematodes

If nematodes attack the culture, then its leaf plates will acquire more rounded shapes, change their color to yellowish-brown, and eventually disappear altogether. These pests live between the bulbous scales, but if conditions are favorable, they will go out into the soil. Preventive measures against nematode damage, such as: 1) Timely disinfection of the planting soil; 2) Disinfection of bulbs with hot water at fifty-fifty-two degrees. Place the bulbs in hot water for at least 10 minutes; 3) Weed crops in the garden and near the plant, must be destroyed as they appear; 4) It is necessary to spray with insecticidal preparations. As insecticidal preparations, you can use agents such as; 1) Pharmayod; 2) Nematophagin; 3) Nemaros; 4) Rogor; 5) Dimethoate; 6) BI-58.

Conclusion

So that you do not have to fight for the life of your beautiful cultures, you need to provide them with comfortable conditions and proper, conscientious care. If you notice signs of damage to the culture, then immediately take the necessary measures to eliminate this problem. Give them love and care, then they thank you with their abundant and bright flowering.
