The cypress tree is over pruned, and the remaining leaves begin to turn yellow, how to take care of

Excessive pruning of cypress trees causes the leaves to turn yellow, and there are several ways to take care of them:

1.Watering: Give the cypress plenty of water to keep the soil moist. If the cypress tree is in a pot, you can regularly check the humidity of the potting soil to keep the potting soil moist but not waterlogged.

2.Fertilization: To provide sufficient nutrients to the cypress, an appropriate amount of organic fertilizer can be applied. Be careful not to apply too much nitrogen fertilizer to avoid overgrowth of branches and leaves.

3.Shade: If the cypress is in a sunny area, consider moving it to a shady location or shading it with a shade net. Avoiding prolonged exposure to the sun and high temperatures can cause the leaves to turn yellow.

4.Pruning: If the yellowing of the cypress tree is severe, consider pruning properly to cut off the yellowing branches and leaves to encourage the growth of new branches and leaves.

5.Pest control: If cypress trees are attacked by pests and diseases, you can consider using appropriate pesticides for control, and at the same time strengthen maintenance management to improve the resistance of cypress trees.

It should be noted that different cypress species and growing environments will be different, and the specific care methods need to be adjusted according to the actual situation. If the condition is more serious, it is advisable to consult a professional horticulturist or plant doctor.

Pruning the lower branches of the trunk in moderation will not harm the growth of the tree, but over-harvesting will be counterproductive. Some cypress trees are harvested to the point of only a few young leaves on the tip, which will reduce the photosynthesis and nutrient absorption of the leaves, affecting the normal growth of the tree. Therefore, cypress branches can be harvested, but they should not be over-pruned.

Cypress trees are hard, woody, have stable roots, and have strong vitality, which is quite effective in preventing soil erosion. But cypress trees grow slowly and should not die.

The yellowing and withering of cypress leaves may be caused by insufficient light, so the cypress tree needs to be moved to a bright place for maintenance. It may also be caused by overwatering, so it is necessary to drain the water in the soil in time and transfer the cypress to a ventilated place for maintenance. It may also be caused by the lack of nutrients, and when the cypress is maintained in the later stage, it is necessary to apply diluted liquid fertilizer every 1 week to supplement nutrients.

Cypress trees are suitable for growing in a sunny environment, if there is a lack of light, it will cause the cypress to appear yellow, dry up, and the growth rate will be slowed down, so the cypress needs to be placed in a bright place for maintenance, and more than 6 hours of light are given every day, so that the cypress can grow vigorously.

Cypress is suitable for growing in a humid environment, but the waterlogging tolerance is poor, when watering the cypress to ensure that the soil is in a slightly moist state, too much watering will cause the soil to produce water, resulting in root rot, the leaves will also be yellow, need to drain the water in the soil in time, and place the cypress in a more ventilated position for maintenance, so that the water can evaporate as soon as possible.

Cypress has a low demand for nutrients during the growth period, but if it is not fertilized for a long time, it will lead to a lack of nutrients in the leaves and rhizomes of the cypress, and the leaves will also appear yellow.

Cypress is suitable for growing in moist slightly acidic soil, if the soil is alkaline or compacted, it will also cause the leaves of cypress to appear yellow, dry condition, you can add an appropriate amount of diluted ferrous sulfate solution to the soil to adjust the pH of the soil, so that the soil is slightly acidic.

Causes and solutions for the yellowing of cypress leaves after pruning.

1. Dry yellow: the yellow of lack of water is not the same as the yellow of water, the yellow of lack of water is the withering and dry leaf tips or edges, and the old leaves are withered and yellow from the bottom to the top, but the growth of new leaves is relatively normal.

Solution: Pay attention to watering when watering enough, water thoroughly.

2. Lack of fat yellow: It is manifested in the color of young leaves becoming lighter, yellow or light green, while old leaves are more normal or gradually turning from green to yellow.

Solution: To check the potting soil frequently, if there is a dry phenomenon, the soil should be replaced, usually thin fertilizer is applied frequently, and some alum water should be poured in a timely manner to supplement iron.

3. Lack of light yellow: If the environment is shaded for a long time, the leaves cannot get enough sunlight and cannot form chlorophyll, and the whole leaves turn yellow and then fall off.

Solution: Timely supplemental light exposure can prevent the disease.

4. Fat yellow: the yellowing of flowers caused by excessive fertilization or excessive concentration is manifested in the dry brown appearance at the top of the new leaf, the general leaf surface is thick and dull, and the concave and convex are not stretched, and the old leaves are scorched and yellow.

Solution: Fertilizer should be stopped immediately, and part of the fertilizer should be washed with a large amount of cleaning.

5. Burning yellow: strong sunlight directly shines on some shade-loving flowers (such as spider plant, hosta, etc.), which is easy to cause the leaf tips and leaf edges of flowers to wither, and the sunny part of the leaves to appear yellow spots.

Solution: In summer, when the sun is too strong, move the plants to semi-shade or shade.

6. Water yellow: the young leaves are dark yellow and dull, the old leaves have no obvious changes, the branches are small yellow-green, and the new shoots are shrunk and not long, indicating excessive watering.

Solution: Depot the flowers and put them in a ventilated and cool place to dry the soil and then put them back into the pot.

When the pine and cypress are cultivated, the leaves often appear yellow, which requires a good grasp of the habits of the pine and cypress, and then take good care of it, in order to prevent the yellow leaves. When the pine and cypress first grow pine needles, the color is slightly pale yellow, which is normal, and it will slowly become more and more green in the later growth process. What to do if the leaves of the pine and cypress trees are yellow, let's talk about it specifically.

1.Soil acidity.

Pines and cypresses prefer loose and fertile acidic soils, and alkaline soils cannot be used to breed pines and cypresses, otherwise the leaves will turn yellow, and the plants will grow slowly or even wilt.

2.Breathability.

You can choose a pot with good air permeability for cultivating pines and cypresses, and put some gravel or old rubble on the bottom of the pot to enhance the drainage function of the soil. The preparation of cultivation soil can mix loess and river sand evenly according to the ratio of 5:5, enhance the air permeability of the soil, and facilitate the growth of pines and cypresses.

3.Watering wisely.

Lack of pines and cypresses or excessive watering will cause the leaves to wither and yellow, you can see dry watering, rather dry than wet, do not accumulate water. If it grows in moist soil for a long time, the leaves of the pine and cypress will gradually turn yellow. After overwatering, pour out the flower pot to pour out the excess water and place it in a well-ventilated place to promote the rapid evaporation of water in the soil.

4.Proper fertilization.

The requirements for fertility of pine stool and cypress are not particularly high, and the appropriate amount of base fertilizer can be added when planting, and then fertilized again after 2-3 years of breeding, excessive topdressing will make the leaves of pine and cypress yellow and dry. After excessive fertilization, it can be properly watered to dilute the fertility in the soil.

5.Pest.

Pine and cypress will rarely be infected with pests and diseases, if the leaves appear yellow, you can observe whether it is sick, spray drugs in time to prevent and control, and use sterilized pruning to cut off dead leaves, diseased and weak branches, and promote the germination of new branches.

It is mainly caused by leaf blight (red leaves) disease and early yellowing caused by biotic and abiotic factors, and the main reasons are as follows:

1. The pathogenic fungus is mainly one species of alternariasp, which infects cypress trees and causes leaf blight.

2. The bite of underground pests on the bark of seedlings is also easy to cause yellow leaves.

3. Yellowing and scorching of leaves caused by lack of fertilizer or unreasonable fertilization.

4. Insufficient soil moisture can not meet the needs of cypress growth and development, resulting in thin or wilted leaves and yellow tips, resulting in early defoliation. Or poor drainage, soil water, resulting in anaerobic respiration of roots for too long, accumulation of excessive alcohol, poisoning and rotten roots. or soil compaction, poor aeration, resulting in yellow leaves.

5. The planting is too dense, the ventilation and light transmission are poor, and the plants compete for fertilizer, water and shade, which affects photosynthesis and large respiratory consumption, resulting in yellowing of leaves and early defoliation.

6. Caused by improper field management. For example, the roots are injured when the seedlings are raised, the roots are nested when planting, and the animals bite the branches or artificially hurt the skin, resulting in yellow leaves.
