What to Do When Common Flower Leaves Turn Yellow? What Are the Treatment Methods

For flowers, if the leaves turn yellow and lose their green color, it indicates that the flowers already have some problems. There are actually many reasons for flower leaves turning yellow, and generally overwatering and overfertilizing are the most common. So how exactly should you deal with flower leaves turning yellow?

Applying too much chemical fertilizer or applying it at the wrong time can cause leaves to wilt and turn yellow (fertilizer burn). For example, if a large amount of chemical fertilizer is applied at one time, or if the soil moisture is insufficient, after fertilization the fertilizer solution concentration in the soil becomes high, causing water in the flower cells to reverse osmosis, resulting in dehydration and wilting of the flowers, and in severe cases death. Some chemical fertilizers, such as ammonium bicarbonate, when applied at relatively high temperatures, easily produce large amounts of ammonia gas, burning the flower leaves. In mild cases, the leaf tips of the lower part of the flower turn yellow; in severe cases, the whole plant turns reddish-yellow and dies. Therefore, when applying chemical fertilizer as a top dressing, the amount used at one time must not be too much; the per-mu amount of urea should not exceed 10 kg. For potted flowers, depending on the size of the pot, applying 1.5-1.0 g per pot is appropriate.

Watering too frequently or long periods of continuous rainy weather keep the soil in a waterlogged state for a relatively long time, reducing oxygen in the soil so that it cannot meet demand, causing abnormal life activities in the flowers, which leads to yellowing and even wilting of the leaves. At this point, watering should be stopped or rain should be avoided to let the soil dry out, so as to improve soil aeration, increase oxygen content, reduce the toxic effects of excess soil carbon dioxide on the flowers, and allow the flowers to grow normally.

What to Do When Flower Leaves Turn Yellow: Simple Methods to Prevent Plant Leaves From Turning Yellow

Today, the editor of Flower Bonsai Network shares with you an article on what to do when flower leaves turn yellow. Here are some simple methods to prevent plant leaves from turning yellow. Let's take a look.

Yellowing leaves have always been a major problem in growing flowers, giving many flower enthusiasts a headache, especially beginners. When they encounter symptoms of yellowing leaves, they have no idea how to treat them at all. So today, Huahua will introduce some care methods for common plants and tell you how to prevent plant leaves from turning yellow!

1. Prevent Money Tree leaves from turning yellow

Pay attention to fertilizing

Money Tree is a flowering woody plant that likes fertilizer. If fertilizer is insufficient, the leaves easily turn yellow. When repotting each year, add an appropriate amount of base fertilizer to the bottom of the pot so that the root system grows stronger.

Add something extra:

For base fertilizer, you can use leaf mold, 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 more so it cannot be exposed to strong sunlight. Especially in summer, every few days you should spray water once with a spray bottle to wash away dust on the leaf surface, increase humidity, and strengthen photosynthesis.

Pay attention to watering

Whether Money Tree can grow well depends very much on watering. Money Tree has an underdeveloped root system and is very sensitive to water. When overwatered, it is especially prone to rot. Each time you water, you must first check whether the soil is dry or wet. Water only when it is dry, otherwise the roots easily rot.

2. Prevent Pothos leaves from turning yellow

Increase humidity

Pothos likes a humid air environment. When the environment is too stuffy, dry, and poorly ventilated, the leaves easily turn yellow.

If conditions allow, you can place the Pothos near a humidifier. If not, you can use a spray bottle to mist the leaves, stems, and aerial roots of the Pothos several times a day.

Add an appropriate amount of water to the saucer of the Pothos pot so that 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 fertilizing

Improper fertilizing of Pothos, whether too much or too little fertilizer, can also easily cause leaves to turn yellow.

Huahua suggests that during the growth period of Pothos, you can spray the Pothos once every half month with urea as a foliar fertilizer.

Add something extra:

Frequently watering with some rice-washing water or fish tank water can also promote more vigorous growth of Pothos.

3. Prevent Areca Palm leaves from turning yellow

Increase air humidity

When the air is dry, Areca Palm leaves easily turn yellow at the edges and become dry and scorched, so you should spray water 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 scorched. In summer, placing it in scattered light is sufficient.

Increase watering amount

In summer, the temperature is high and evaporation is fast. If water is insufficient, it easily causes the leaf tips of Areca Palm to dry and turn yellow, so water should be replenished in time.

Add something extra:

To avoid excessive watering causing water accumulation at the roots, when repotting Areca Palm, you can place some coal cinder or broken tile pieces at the bottom of the pot.

4. Prevent Lucky Bamboo leaves from turning yellow

Increase iron

Iron deficiency is an important cause of Lucky Bamboo turning yellow. You can go to a flower market and buy a packet of ferrous sulfate to supplement iron.

Add something extra:

When growing Lucky Bamboo in water, you can also put a few iron nails in the water cultivation bottle.

Reduce light

Summer light is strong, so be sure not to place Lucky Bamboo under strong light and expose it to the sun, otherwise the leaves easily become dry and yellow. When growing Lucky Bamboo in water in summer, placing it indoors is enough; ordinary light can meet its growth needs.

5. Prevent Anthurium leaves from turning yellow

Increase light

Sometimes we find that both the old leaves 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 exposure to strong sunlight.

Fertilize reasonably

Insufficient fertilizer leads to weak growth, so of course the leaves easily turn yellow. When fertilizing Anthurium, generally choose a fertilizer with an N-P-K ratio of 1:1:1, dilute it a thousand times, and apply it once every seven days. You can also buy special fertilizer for Anthurium to help it grow better.

Add something extra:

To help Anthurium grow better, you can bury cooked soybeans in the soil of the Anthurium. Burying three or four grains in one flower pot is enough. It is simple, practical, and convenient.

6. Prevent Spider Plant leaves from turning yellow

Water appropriately

Spider Plant likes a humid environment, and the soil should remain moist often, but there must be no water accumulation, because Spider Plant has fleshy roots and water accumulation 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, apply liquid fertilizer to Pothos once every half month. You can also buy special fertilizer for Spider Plant to make the plant grow more vigorously.

Add something extra:

Spider Plant can also be frequently watered with some rice-washing water, fish tank water, expired milk, and so on, to promote healthy plant growth.

Provide appropriate shade

Spider Plant likes a semi-shaded environment. In summer, avoid exposure to strong sunlight and place it indoors in scattered light for care. When the air is dry, spray water on the leaf surface and surroundings more often.

7. Prevent Ivy leaves from turning yellow

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 around a humidifier.

Fertilize appropriately

During the growing season of Ivy, apply a thin cake fertilizer as a top dressing 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 it easily causes the leaves to scorch.

Add something extra:

Dilute beer 10 times and use it to spray the leaves of Ivy, which can make the leaves more dark green.

8. Prevent Asparagus Fern leaves from turning yellow

Water reasonably

If you want Asparagus Fern not to turn yellow, watering is key. If overwatered, the branches and leaves easily turn yellow, growth is poor, and root rot is also likely. If you are not good at judging moisture, you can use the method of alternating large and small waterings: after watering three or four times with a small amount, water thoroughly once with a large amount, keeping the potting soil moist without water accumulation.

Fertilize reasonably

Asparagus Fern does not need much fertilizer, but insufficient fertilizer also easily causes yellow leaves. During the growing season of Asparagus Fern, generally apply decomposed organic fertilizer as a top dressing once every half month. In addition, you can water the Asparagus Fern with some alum fertilizer water to promote healthy growth.

Add something extra:

Dilute fermented cake fertilizer 10 to 20 times and water the Asparagus Fern with it, which can make the Asparagus Fern lush with branches and leaves.

9. Prevent Dragon Tree leaves from turning yellow

Water appropriately

Dragon 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 leaf surface of the Dragon Tree every morning or evening to avoid dry yellow leaves caused by dry air.

Reduce pests and diseases

When Dragon Tree is kept indoors, poor ventilation easily attracts red spider mites, which destroy chlorophyll and cause leaves to fade. When you find abnormal symptoms on the leaves, be sure to check the leaves in time, and once discovered, treat immediately. You can spray the leaves with dichlorvos or dicofol emulsion.

Add something extra:

To prevent Dragon Tree from being infected by red spider mites, you can soak orange peel in water for a day and night, filter it, and spray the plant with it, which can be effective.

What to Do When Flower Leaves Turn Yellow, 11 Causes of Flower Leaves Turning Yellow

Causes of flower leaves turning yellow include water-yellow, drought-yellow, light-yellow, starvation-yellow, and fertilizer-yellow. The yellowing of flower and tree leaves is also affected by soil pH, pests and diseases, pesticide damage, smoke and dust, and changes in humidity levels. An imbalanced ratio of trace elements in the soil and poor ventilation and other factors can also cause leaves to turn yellow. As for the metabolism of branches and leaves, temporary imbalance of nutrients and water after transplanting, and leaf shedding during the dormant period, these are normal physiological phenomena of plants. The following is an analysis of common causes of yellowing leaves

The potting soil remains too wet for a long time, causing oxygen deficiency in the soil, rotting some fibrous roots, hindering normal respiration and the absorption of water and nutrients, and causing leaves to turn yellow and fall off. After being affected, the young leaves first turn pale yellow, and then the old leaves gradually turn yellow as well. Watering should be controlled immediately, fertilization should be suspended, and the soil should be loosened frequently to improve aeration.

Missing watering when growing flowers or watering only halfway for a long time (that is, wet on top and dry below) affects nutrient absorption and also easily causes the leaf color to become dull and lusterless, with leaves wilting and drooping. First the lower old leaves age, and gradually wither, yellow, and fall off from bottom to top. At this point, water lightly and spray water to help them gradually recover, then return to normal watering.

If no nitrogen fertilizer has been applied for a long time or the pot and soil have not been changed, the soil lacks nitrogen and other nutrient elements, causing branches and leaves to become weak and thin, with thin and yellow leaves. The pot should be changed in time, replacing it with new loose and fertile culture soil, and gradually applying more thin decomposed liquid fertilizer or compound flower fertilizer.

If too much fertilizer is applied, new leaves will become thick and fleshy, and often uneven, while old leaves will dry at the tips, scorch yellow, and fall off. Fertilization should be stopped immediately, watering should be increased so that fertilizer flows out from the drainage hole at the bottom of the pot, or the pot should be changed immediately, the root ball washed with water, and then replanted in the pot.

In summer, if cool-loving flowers (such as Cyclamen, Fuchsia, and Wax Begonia) are placed in a high-temperature location and exposed to direct strong light, it very easily causes the leaf tips and leaf margins of young leaves to scorch, or leaves to turn yellow and fall off. They should be moved in time to a cool place with good ventilation.

If sun-loving flowers are placed in a shaded area or a place with insufficient light for a long time, the branches and leaves will grow leggy, the leaves will be thin and yellow, and they will not bloom or bloom very little. Be careful to move the flower pot to a sunny place.

In most areas of the north, the soil and water contain relatively more salt and alkali. When planting acid-loving flowers such as Rhododendron, Camellia, Michelia figo, Gardenia, Orchid, Michelia alba, and Osmanthus, because the soil lacks soluble iron and other elements that they can absorb, the leaves gradually turn yellow. When planting, choose acidic soil, and frequently water with alum fertilizer water during the growing period.

If too much nitrogen fertilizer is applied, the branches and leaves grow too luxuriantly, and if they are not pruned for a long time, the inner branches and leaves do not receive enough light, which easily causes leaves to turn yellow and fall off. Fertilize reasonably and strengthen pruning to provide ventilation and light.

When indoor air is excessively dry, some flowers that like humid environments, such as Spider Plant and Orchid, often show dry leaf tips or scorched leaf margins. Attention should be paid to increasing air humidity by methods such as spraying water and covering with plastic film.

If the indoor temperature is too low in winter, flowers that like high temperatures are often susceptible to cold damage, which causes leaves to turn yellow, and in severe cases they wither, yellow, and die. If the indoor temperature is too high, the plant's transpiration is excessive, and the roots cannot supply water and nutrients quickly enough, which also causes leaves to turn yellow. Please pay attention to adjusting the indoor temperature in time.

Red soil in the south tends to be acidic, and elements such as magnesium are easily lost. When planting trees and flowers that are alkali tolerant or prefer slightly alkaline soil, such as oleander, boxwood, and winter jasmine, the phenomenon of yellowing between the veins of old leaves often easily appears. You can apply calcium magnesium phosphate fertilizer or spray magnesium sulfate solution.
