What to do when the leaves of lily 'Perfume' turn yellow? Water and fertilize properly and spray to prevent pests and diseases

The lily 'Perfume', queen among the hundred flowers, has graceful blooms and rich colors, and is extremely ornamental when grown at home. In daily life, many people grow the lily 'Perfume', but during care, quite a few flower lovers end up turning the leaves yellow. So what should be done when the leaves of lily 'Perfume' turn yellow? At this point, flower lovers should calmly find the cause, then handle it accordingly. Today the editor will help everyone solve this problem.

I. When the leaves of lily 'Perfume' turn yellow, find the cause

As a beautiful flower, the lily 'Perfume' is a common indoor potted plant, but unfortunately there are too many novice growers, and they have little growing experience, so they don't know how to water and don't know how to fertilize, and all of this can cause the leaves of lily 'Perfume' to turn yellow, thus affecting the plant's ornamental value. To solve this problem, the editor has summarized several causes of yellowing leaves in lily 'Perfume'. Let's read on.

II. Causes of yellowing leaves in lily 'Perfume' and their solutions

1. Sudden environmental change

There are actually many causes of yellowing leaves in lily 'Perfume', but you can first consider whether there is a problem with the growing environment. Nowadays the internet is very developed, and many flower lovers buy their potted lily 'Perfume' online, which may cause a relatively large environmental change, and the plant cannot adapt for a while, thus showing symptoms of yellow leaves.

Solution: Very simple, ask the shop about the lily 'Perfume''s previous growing environment, then adjust the environment at home until the lily 'Perfume' fully adapts. After normal care for a period of time, the plant's leaves will recover.

2. Improper watering

Watering is a technical skill, especially for beginners; when watering lily 'Perfume', neither too much nor too little will do. Once there is overwatering or a lack of water, the symptom of yellowing leaves in lily 'Perfume' will appear.

① Too much watering: the old leaves of lily 'Perfume' show no obvious change, while the young leaves turn yellow. Solution: stop watering, move the potted plant to a ventilated, sunny spot, and let the moisture evaporate quickly; if it is severe enough to cause root rot, cut off the rotten roots, replace the potting soil, then replant.

② Too little watering: the plant's old leaves turn yellow first from the bottom up; if the water shortage lasts a little longer, the whole plant's leaves will turn yellow, and it may even die. Solution: water moderately, judging by keeping the potting soil moist, then care for it carefully for a period of time, and the leaves will recover.

3. Improper fertilizing

Having covered watering, let's talk about fertilizing, which is also one of the causes of yellowing leaves in lily 'Perfume'. During growth, lily 'Perfume' needs a large amount of nutrients, but it also dislikes too much fertilizer, so neither too much nor too little fertilizing will do.

① Too much fertilizer: the young leaves of lily 'Perfume' become thick and fleshy, glossy, and uneven. Solution: stop fertilizing, then water heavily to dilute the fertilizer and let the excess fertilizer drain out of the pot; in severe cases, cut off the rotten roots, replace the potting soil, and replant.

② Too little fertilizer: the plant's young leaves and tender stems turn yellow first; if not discovered in time, it will cause the whole plant's leaves to turn yellow and may even kill it. Solution: fertilize lily 'Perfume' in the right amount, but never apply a large amount of concentrated fertilizer at one time, to avoid burning the roots.

4. Unsuitable soil

In the growing methods for lily 'Perfume', it was mentioned that it likes deep, well-drained, fertile, slightly acidic soil. Once the soil leans alkaline, it will cause lily 'Perfume' to lack iron, thus producing the yellow-leaf phenomenon. Characteristics: obvious on young leaves, lighter on old leaves, leaf flesh yellow, leaf veins green, forming a typical network.

Solution: If the above symptoms appear and it is judged to be caused by alkaline soil, flower lovers can apply ferrous sulfate aqueous solution (made from 7 parts cake fertilizer, 5 parts ferrous sulfate, 200 parts water) to solve it.

5. Pests and diseases

During the growing process of lily 'Perfume', due to improper care and other reasons, the plant will inevitably get insects and diseases. Once pests or diseases are found, it is fine if handled in time; once they are not found in time, the phenomenon of yellowing leaves in lily 'Perfume' will appear.

Solution: First determine which pest or disease it is, then spray the corresponding pesticide to solve it. As for which pesticide to spray, you can refer to the pest and disease control for lily 'Perfume', which has detailed introductions; interested flower lovers can take a look.

Overall, lily 'Perfume' is still quite easy to grow, but because many flower lovers are beginners, the yellow-leaf symptom will inevitably appear. However, after reading the whole article, I believe everyone has a clearer idea. When the yellow-leaf problem appears, just handle it according to the methods above. That is all the editor has to introduce about yellowing leaves in lily 'Perfume', hoping it can help everyone.

What to do when lily leaves turn yellow?

[Common question] What to do when lily leaves turn yellow?

[Expert answer] Analysis of the causes of yellowing lily leaves and treatment methods:

1. Overwatering causes lily leaves to turn yellow (water yellowing):The young leaves are dark yellow and lack luster, the old leaves show no obvious change, the branches are thin and yellow-green, and the new shoots shrink and stop growing, indicating overwatering.

Solution: Take the plant out of the pot, place it in a ventilated, shady spot to let the root ball dry on its own, then put it back in the pot.

2. Long-term water shortage causes lily leaves to turn yellow (drought yellowing):The yellowing from water shortage is different from the yellowing from too much water; the yellowing from water shortage shows the leaf tips or edges becoming withered and dry, and the old leaves withering yellow and falling from the bottom up, but the new leaves grow relatively normally.

Solution: Just be careful to water enough and water thoroughly.

3. Scorching sun causes lily leaves to turn yellow (scorch yellowing):Strong direct sunlight shining on some shade-loving flowers easily causes the leaf tips and leaf edges to wither and yellow spots to appear on the sun-facing part of the leaves.

Solution: Just move it to a shady spot.

4. Dry air causes lily leaves to turn yellow:When indoor air is excessively dry, some flowers that like humid environments, such as spider plants and orchids, often show phenomena such as dry leaf tips or scorched leaf edges.

Solution: Pay attention to methods such as misting and covering with plastic film to increase air humidity.

5. Insufficient sunlight causes lily leaves to turn yellow (light-deficiency yellowing):Placed in a shady environment for a long time, the leaves cannot get enough sunlight and cannot form chlorophyll, so the whole plant's leaves turn yellow and then fall off.

Solution: Be careful to move the flower pot to a sunny spot.

6. Too-low temperature causes lily leaves to turn yellow:When the winter room temperature is too low, flowers that like high temperatures are often easily harmed by cold, thus causing the leaves to turn yellow, and in severe cases to wither, yellow and die. If the room temperature is too high, the plant's transpiration is excessive, and the roots cannot supply enough water and nutrients, which will also make the leaves turn yellow.

Solution: Pay attention to adjusting the room temperature in time.

7. Too much fertilizer causes lily leaves to turn yellow (fertilizer yellowing):Too much fertilizer will cause the new leaves to become thick and fleshy with many bumps, and the old leaves to dry at the tips, scorch yellow and fall off.

Solution: Stop fertilizing immediately, increase the amount of watering so the fertilizer flows out from the drainage holes at the bottom of the pot, or immediately empty the pot, rinse the root ball with water, then replant it in the pot.

8. Long-term lack of fertilizer causes lily leaves to turn yellow (fertilizer-deficiency yellowing):The young leaves become lighter in color, appearing yellow or pale green, while the old leaves are relatively normal or gradually turn from green to yellow.

Solution: Check the potting soil; if there is dry caking, replace the soil, usually apply thin fertilizer frequently and water with some alum water at the right time.

9. Pests and diseases cause lily leaves to turn yellow:Leaf spot disease caused by fungal and other pathogenic infections easily causes local necrosis of the leaves, with yellow spots or patches appearing, and in severe cases the whole leaf withers, yellows and falls off; after infection by mosaic virus, yellow-green mottled patches appear on the leaves; when harmed by scale insects, red spiders and the like, the leaves also become locally yellow and withered, and may even wither, yellow and fall off entirely.

Solution: Spray pesticide in time for prevention and control.

What to do when lily leaves turn yellow: causes of yellowing lily leaves

Lily, a perennial herbaceous bulb plant of the genus Lilium in the family Liliaceae. What should we do when we encounter yellowing lily leaves during the growing process? Below we will explain the causes of yellowing lily leaves.

I. Water yellowing. Overwatering easily causes the potting soil to stay waterlogged for a long time, suffocating and rotting the root system, thereby causing yellow leaves and even leaf drop; its characteristic is that the old leaves show no obvious change while the young leaves turn yellow. For yellow leaves caused by excessively wet soil, watering should be stopped, the soil loosened, and it should be allowed to ventilate and dry.

II. Drought yellowing. Caused by water shortage and drought, its characteristic is that the old leaves turn yellow first from the bottom up; if the water shortage lasts a little longer, the whole plant's leaves will turn yellow, and it may even die. It should be watered at the right time, adhering to the principle of "water when dry, stop when wet, and water thoroughly when watering".

III. Fertilizer yellowing. Caused by fertilizing too frequently or at too high a concentration; its characteristic is that the young leaves become thick and fleshy, glossy, and uneven. Fertilizing should be controlled, the soil cultivated, and watering done; in summer apply a thin fertilizer once a week. If too much fertilizer has already been applied, water more to dilute it and wash away the fertilizer in the soil.

IV. Starvation yellowing. During the growing period of potted lilies, not fertilizing for a long time or insufficient fertilizing will cause the yellow-leaf phenomenon. Its characteristic is that the young leaves and tender stems turn yellow first. A lack of fertilizer also causes the potting soil to harden, and the branches to become thin, long, yellow and tender. Fertilize immediately, and results will be seen within a week.

V. Nutrient-imbalance yellowing leaves: Lilies have a relatively large need for nitrogen and potassium fertilizers, and during the growing period they should be applied once every 10-15 days, while the supply of phosphate fertilizer should be limited, because too much phosphate fertilizer will cause the leaves to wither and yellow.

VI. Iron-deficiency yellowing leaves. Lilies are sensitive to soil salt, and the soil pH is 5.5-6.5. High alkalinity will cause the physiological disease of iron-deficiency chlorosis. To monitor the pH of fertilizer and water, you can use wide-range PH test paper, sold at western pharmacies and medical equipment stores (2 yuan a book, usable for a very long time)

VII. Yellowing leaves during the potting-in period: For newly potted or repotted plants, because the root system is injured and the plant cannot adapt to the new environment (potting soil, water quality, environmental humidity and temperature), yellowing leaves are most likely to occur. At this time it should be kept in shade for care, no fertilizing, water only when the soil is thoroughly dry and then water thoroughly, mist the leaves, and wait until new leaves grow before returning to normal care.

VIII. Pests and diseases: Harm from pests and diseases can also cause leaves to turn yellow. Remove pests and diseases in time.
