Why do lily leaves turn yellow and what happens to lily leaves turn yellow

The yellowing of the lily's leaves may be due to excessive watering during maintenance, which has caused waterlogging at the roots. It may also be because it is usually fertilized too much, so that its root system is damaged by residual flower fertilizer. It is also possible that the soil has hardened, causing its root system to rot.

All of these causes can cause it to appear yellow leaves. Lily, scientific name (also known as Qiangshu, Leek, Shandan, Fallen Immortal, Chongmai, Atrium, Moro, Chongbox, Zhongfenghua, Lily Garlic, Master Fu Garlic, Garlic Brain Potato, Nocturnal Lilia, etc.), is a perennial herbaceous bulbous plant of the Liliaceae family Liliaceae (scientific name: lilium), native to China, mainly distributed in eastern Asia, Europe, North America and other temperate regions of the northern hemisphere, at least 120 varieties have been found in the world, of which 55 species are produced in China.

In recent years, there have been many new varieties produced through artificial hybridization, such as Asian lily, perfume lily, fire lily, etc. The bulb is rich in starch, edible and also used for medicinal purposes.

There are several reasons why lily leaves can turn yellow:

1. Excessive watering leads to long-term dampness of the potting soil, resulting in hypoxia in the simple soil, causing some fibrous roots to rot, hindering normal respiration and absorption of water and nutrients, and causing the leaves to turn yellow and fall off;

2. Drought and dehydration, resulting in the impact of nutrient absorption, causing the leaf color to be dull and dull, the leaves wilting and drooping, and gradually withering and falling off from the bottom to the top;

3. Long-term defertilization, long-term no ammonia fertilizer or no pot and soil change, will make the nutrients in the soil slippery and lacking, resulting in thin branches and leaves, and leaf yellow falling off;

4. Excessive fertilization, too much fertilization will cause new leaves to be hypertrophied, and uneven, and the old leaves are scorched and fall off;

5. In the hot and high temperature, put the letter block plant in a high temperature place to let the strong light shine directly, which is easy to cause the tip and leaf edge of the young leaf to be scorched, resulting in the leaf yellow falling off.

Reason: After cultivating lilies for a period of time, the soil used for cultivation is easy to become hard, and the poor air permeability of the soil will affect the growth of roots, and the leaves will turn yellow in the long run.

Solution: Loosen the soil immediately, or replace the old soil with a new breathable soil.

Reason: It does not like to grow in too humid environments, so if there is standing water in the pot, it will cause root rot, the root system cannot breathe and grow normally, and the leaves are prone to yellowing.

Solution: It should be placed in a ventilated position, so that the excess water can accelerate the evaporation, and properly control the amount of watering, so that the maintenance will recover after a period of time.

Reason: If you do not fertilize for a long time during the breeding period, the soil will lack nutrients, and there will be yellow leaf symptoms, which is iron deficiency yellow leaf.

Solution: At this time, the plant needs to be supplemented with some iron, and some ferrous sulfate solution can be applied to it. When fertilizing at ordinary times, the nutrients should be as balanced as possible.

The choice of pots.

The original loose chop compound for the yellowing of lilies depends largely on the planting location. Planting lilies usually requires choosing a suitable growing environment. The choice of flower pot should be a sand pot, and it is best not to choose a plastic pot or a porcelain pot.

The second is the height of mutual spraying. Generally, it is better to choose a taller pot, so that it can grow more vigorously with the roots of the lily. The development of roots affects the growth of branches and leaves.

If the root system of the finger does not develop normally, it will lead to insufficient nutrient absorption and yellow leaves. But the pot should not be too big, it will also affect the growth of the whole plant. Depending on the size of the plant's growth, choose a pot of the right size.

Use of fertilizers.

When garlic is grown, the application of fertilizer can also affect the growth of the plant. Usually most people prefer to use the soil of their choice and then use liquid fertilizer. Sometimes you can put a small amount of fertilizer at the bottom of the pot as a base fertilizer.

Fertilizer must be used, which can supplement nutrients, but you must pay attention to the amount and fertilize appropriately according to the growth of lilies.

Illumination. Eupatorium purpurea prefers to grow in places with light. It is a shade-loving plant, so we should avoid direct sunlight and unnecessary damage to the leaves.

If the leaves turn yellow, there may not be enough time to look for them. At this time, they should be kept in a place with light. In summer, reduce the amount of light time the lilies spend in a bright environment so that the leaves do not turn yellow due to strong light.

The reason why the lily leaves turn yellow from the bottom to the top is that the soil is not suitable, there is a lack of nutrients, and the pot is too small.

1. The soil is not suitable.

Sometimes the lily leaves turn yellow from the bottom up, which is actually caused by the unsuitable soil. Lily is an acidic plant, its soil must be slightly acidic soil containing humus, if the soil is alkalized and dry, it will affect the lily's absorption of nutrients, and the leaves of the plant will slowly dry up and fall off.

2. Lack of nutrients.

The branches and leaves of the lily slowly turn yellow from the bottom upwards, mostly because the plants do not absorb nutrients and water. When the plant lacks water and fertilizer, it will cause the yellowing and yellowing of the plant. Once yellowing, it must start with the leaf part, and the plant will slowly enter a state of dehydration.

3. The flower pot is too small.

The roots of lilies are bulbous roots, which not only take up a lot of space, but stacking them too closely can cause the plants to be uncomfortable and even unable to absorb nutrients. Sometimes the leaves of the lily turn yellow because the pot is too small, which will trap the nutrients of the plant and hinder the nutrient absorption of the lily plant.

The solution to the yellowing of lily leaves from the bottom up

The soil of the lily has dried up, so it is necessary to replace the soil immediately, preferably loose and permeable sandy soil, and then add some humus peat. Pair the sand with the peat, then add some pearlstone to 5:4:

The ratio of 1 is mixed to ensure the nutrients of the soil.

Add water to the plant first, water the soaked soil, wait until the plant has absorbed 2-3 days of water, and then add fertilizer, pay attention to the diluted fertilizer first, and slowly add the amount later, so that the plant will slowly recover. Once the pot is too small and the plant is not growing well, it is necessary to change the pot immediately. Otherwise, the leaves of the plant will turn yellow, and the pot of the lily will be replaced with a shallower pot with a larger diameter, which is very suitable for the growth of the lily plant.

There are many reasons for the yellowing of the lily leaves from bottom to top, if it is too much watering, stop watering in time, each watering should be deeply cultivated, too much fertilization should be stopped, fertilization should be mainly thin fertilizer, the pot is too small to change the pot in time, transplant after re-matching the soil, and also do a good job of preventing diseases.

1. Overwatering

Lilies have a certain ability to tolerate drought, even if they do not water for a few days under normal circumstances, they will not wither and die, if they are watered too much, they will cause water accumulation in the potting soil, and the young leaves will turn yellow in large quantities, which is also the main reason why the lily leaves are yellowing from the bottom to the top.

2. Excessive fertilization

Lily on fertilizer requirements are not high, if the fertilization is too frequent or the concentration is too large, it is easy to cause the phenomenon of fat yellowing, resulting in root rot branches and leaves will also be yellow, at this time should stop fertilization, after each fertilization of deep ploughing treatment, so that the nutrient distribution is more uniform, in order to facilitate the absorption of the root system.

3. Change the pot

Lily is a bulbous plant, the root system will stretch around during the growth process, if the pot is too small, it will inhibit the growth and development of the root system, and it will cause root rot for a long time, and the branches and leaves will be a large number of yellowing.

4. Caused by disease

The diseases that often occur in lilies are mainly the harm of virus disease and leaf blight, the harm of this kind is relatively large, most of them are caused by poor ventilation or improper watering, and it will lead to a large number of wilts for a long time.
