What to do when flower leaves turn yellow? Let me teach you prevention and treatment methods
During the growth process, flowers are very prone to yellowing leaves for various reasons. At this time, you must first figure out the cause before treating it, so that the flowers can recover as quickly as possible. The editor will introduce to you three common causes and prevention methods for yellow leaves in flowers. Flower lovers who need it can learn from this.

1. If leaves droop due to lack of water, immediately spray water on the leaves to speed up the plant's absorption of water, and then water the pot. At this time, note that you should water less, just keep the soil moist, and do not water too much.
2. During the growing period of potted flowers, not fertilizing for a long time or insufficient fertilization can cause yellow leaves; applying too much concentrated fertilizer will burn the roots, affect water absorption, and also cause yellow leaves. You can water more to dilute it and wash away the fertilizer in the soil. A lack of fertilizer can cause the potting soil to compact, with leaves yellow, thin, and weak, and branches slender, yellow, and tender. Fertilizer should be applied immediately. At the same time, spraying Duoduo Zhuangdiling can promote strong flower buds, plump petals, bright flower colors, rich fragrance, and extended flowering period.
3. Pests and diseases. After being infected by mosaic virus, yellow-green mottled patches often appear on the leaf surface. Attention should be paid to prevention, and Xinshi Gao Zhi Mo should be sprayed in time, with sufficient light and ventilation provided. Aphids, red spiders, and others suck nutrients and water on the underside of leaves, causing leaves to wither and yellow or even the whole plant's leaves to wither and fall off. Timely pest control can restore them.
Prevention and treatment of yellowing leaves in household flowers
During the growth process, flowers often develop yellow leaves, and the cause is mostly improper cultivation and management. Too much or too little water, too strong or too weak sunlight, and too much or too little fertilizer can all cause leaves to turn yellow, but the yellowing conditions differ. The causes should be carefully observed and analyzed, and management should be carried out in time.
1. Water yellowing: tender leaves are dull yellow and lack luster, old leaves show no obvious change, branches are thin and yellow-green, and new shoots shrink and do not grow, indicating overwatering. Remove the flower from the pot, place it in a ventilated and cool place to let the soil ball dry naturally, and then put it back into the pot.
2. Drought yellowing: yellowing caused by lack of water is different from yellowing caused by too much water. Yellowing due to lack of water shows leaf tips or edges becoming scorched and dry, old leaves withering and yellowing from bottom to top and falling off, but new leaves grow relatively normally. Just pay attention to watering thoroughly and sufficiently.
3. Scorch yellowing: strong direct sunlight shining on some shade-loving flowers (such as spider plant, hosta, etc.) easily causes leaf tips and leaf edges to scorch, and yellow patches to appear on the sun-facing parts of the leaves. Just move them to a shady place.
4. Light-deficiency yellowing: being placed in a shaded environment for a long time prevents the leaves from getting enough sunlight and forming chlorophyll, so the whole plant's leaves turn yellow and then fall off. Supplementing light can avoid this problem.
5. Fertilizer yellowing: flower yellowing caused by excessive fertilization or too high concentration shows dry brown tips on new leaves. Generally, the leaf surface is thick and lacks luster, and is uneven and not smooth, while old leaves scorch yellow and fall off. Stop fertilizing immediately; in severe cases, use a large amount of clean water to wash away part of the fertilizer.
6. Fertilizer-deficiency yellowing: this shows the color of tender leaves becoming lighter, yellow or pale green, while old leaves are relatively normal or gradually turn from green to yellow. 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 appropriate time.
What to do when flower leaves turn yellow: simple methods to avoid plant leaves turning yellow
What the Flower and Bonsai Network editor is sharing with you today is an article about what to do when flower leaves turn yellow. Here are some simple methods to avoid plant leaves turning yellow. Let's take a look.
Yellow leaves have always been a major problem in flower growing, giving many flower lovers a headache, especially beginners. When they encounter symptoms of yellow leaves, they have no idea how to treat them. So today, Huahua will introduce some care methods for common plants and tell you how to avoid plant leaves turning yellow!
1. Avoid yellowing in money tree
Pay attention to fertilization
Money tree is a flowering woody plant that likes fertilizer. If fertilizer is insufficient, the leaves are prone to turning yellow. When repotting each year, add an appropriate amount of base fertilizer to the bottom of the pot so the root system grows stronger.
Add something:
For base fertilizer, you can use leaf mold made from fallen leaves, mixed with some garden soil, soybean cake residue, and crushed bone residue, but it must be fully decomposed and fermented before use.
Pay attention to light
Money tree likes a warm and humid environment. It cannot be placed in an environment without light for a long time, and even less can it be exposed to strong sun. Especially in summer, every few days, use a spray bottle to spray water once to wash away dust on the leaf surface, increase humidity, and strengthen photosynthesis.
Pay attention to watering
Whether the money tree grows well depends greatly on watering. The money tree's root system is not well developed and is very sensitive to water. When overwatered, it is especially easy to rot. Each time you water, be sure to first check whether the soil is dry or wet, and water only when it is dry; otherwise, the roots are very likely to rot.
2. Avoid yellowing in pothos
Increase humidity
Pothos likes a humid air environment. When the environment is too stuffy, dry, and poorly ventilated, the leaves are prone to turning yellow.
If conditions allow, place the pothos near a humidifier. If not, use a spray bottle to spray the leaves, stems, and aerial roots of the pothos several times a day.
Add an appropriate amount of water to the saucer under the pothos pot so it evaporates and increases air humidity.
When the air is severely dry, you can cover the entire pot of pothos with a plastic bag to create a small humid environment.
Pay attention to fertilization
Improper fertilization of pothos, whether too much or too little fertilizer, can easily cause leaves to turn yellow.
Huahua suggests that during the pothos growing period, you can spray the pothos with urea once every half month as a foliar fertilizer.
Add something:
Frequently watering with rice water or fish tank water can also promote more vigorous growth in pothos.
3. Avoid yellowing in areca palm
Increase air humidity
When the air is dry, areca palm leaves easily turn yellow at the edges and become dry and scorched, so water should be sprayed on the leaf surface and surroundings three or four times a day.
Reduce light
From May to September, areca palm must grow in a semi-shaded environment. If the light is too strong, the leaves of areca palm will turn yellow and scorch. In summer, placing it in bright indirect light is sufficient.
Increase watering amount
In summer, temperatures are high and evaporation is fast. If water is insufficient, it easily causes areca palm leaf tips to dry and turn yellow, so water should be replenished in time.
Add something:
To avoid excessive watering causing water accumulation at the roots, when repotting areca palm, you can place some coal cinders, broken tiles, and the like at the bottom of the pot.
4. Avoid yellowing in lucky bamboo
Increase iron elements
Iron deficiency is an important cause of yellowing in lucky bamboo. You can go to a flower market and buy a packet of ferrous sulfate to supplement iron elements.
Add something:
When growing lucky bamboo in water, you can also put a few iron nails into the water culture bottle.
Reduce light
Summer light is strong, so be sure not to place lucky bamboo in strong light for sun exposure, otherwise the leaves can easily become dry and yellow. When growing lucky bamboo in water in summer, placing it indoors is enough; ordinary light can generally meet its growth needs.
5. Avoid yellowing in anthurium
Increase light
Sometimes we find that both the old and new leaves of anthurium have turned yellow. At this time, the likely reason is that the light is too weak. Check the growing environment of the anthurium and appropriately increase light as needed, while being careful to avoid sun exposure.
Fertilize reasonably
Insufficient fertilizer leads to weak growth, and of course yellow leaves are likely. When fertilizing anthurium, generally choose a fertilizer with a nitrogen-phosphorus-potassium ratio of 1:1:1, dilute it a thousand times, and use it once every seven days. You can also buy special fertilizer for anthurium to help it grow better.
Add something:
To help the anthurium grow better, you can bury cooked soybeans in the anthurium's soil. Burying three or four in one flowerpot is enough. It is simple, practical, and convenient.
6. Avoid yellowing in spider plant
Water appropriately
Spider plant likes a humid environment. The soil should often remain moist, but there must be no standing water, because spider plant has fleshy roots, and standing water easily causes root rot. Spider plant is very drought tolerant; it is better to let it dry than to let water accumulate.
Fertilize reasonably
During the growing season, water pothos with liquid fertilizer once every half month. You can also buy special fertilizer for spider plant to make the plant grow more vigorously.
Add something:
Spider plant can also be frequently watered with some rice water, fish tank water, expired milk, and the like to promote healthy plant growth.
Provide appropriate shade
Spider plant likes a semi-shaded environment. In summer, avoid sun exposure and keep it indoors in bright indirect light. When the air is dry, spray water on the leaves and surroundings more often.
7. Avoid yellowing in ivy
Strengthen air humidity
The growth of ivy requires relatively high air humidity, especially in summer. On the one hand, water in time to keep the soil moist; on the other hand, spray water more often, or place the ivy near a humidifier.
Fertilize appropriately
During the growth season of ivy, apply a thin cake fertilizer once every two to three weeks. Try not to fertilize in summer and winter. Also, when fertilizing, be careful not to get it on the leaves, as the leaves can easily scorch.
Add something:
Dilute beer 10 times and use it to spray ivy leaves, which can make the leaves more deep green.
8. Avoid yellowing in asparagus fern
Water reasonably
If you want asparagus fern not to turn yellow, watering is key. If overwatered, the branches and leaves easily turn yellow, grow poorly, and are also prone to root rot. If you are not good at judging water, you can use the method of alternating large and small waterings: after watering three or four small waterings, water thoroughly once with a large watering, keeping the potting soil moist without standing water.
Fertilize reasonably
Asparagus fern does not need much fertilizer, but insufficient fertilizer can also easily cause yellow leaves. During the growth season of asparagus fern, generally apply decomposed organic fertilizer once every half month. In addition, you can water asparagus fern with some alum fertilizer water to promote healthy growth.
Add something:
Dilute fermented cake fertilizer 10 to 20 times and use it to water asparagus fern, which can make asparagus fern flourish with dense branches and leaves.
9. Avoid yellowing in dragon blood tree
Water appropriately
Dragon blood tree likes a warm and humid environment and a place with sufficient light. In summer, water once every 3~5 days to keep the soil moist. You can spray water on the dragon blood tree leaves every morning or evening to avoid leaves becoming dry and yellow caused by dry air.
Reduce pests and diseases
When dragon blood tree is kept indoors, poor ventilation makes it easy to attract red spiders, which damage chlorophyll and cause leaves to fade. When symptoms of discomfort appear on the leaves, be sure to inspect the leaves in time. Once found, treat immediately. You can spray the leaves with dichlorvos or trichlorfon emulsifiable concentrate.
Add something:
To prevent dragon blood tree from being infected by red spiders, you can soak orange peel in water for a day and night, filter it, and spray the plant, which can be effective.
