There are rusty spots on the leaves of cochinese, what s going on

Coxagulus. Rust spots on the leaves are caused by several reasons:

1. Infection with rust. Orange, yellow or red spots appear on the leaves of the cochine, which gradually turn into patches. This is because the humidity is relatively high, especially in rainy weather, and the leaves are more susceptible.

2. After the soil is alkaline, brown spots will also appear on the leaves of Cog. japoonus.

3. There are some alkaline mineral residues in the soil of the leaves of Coxagulus.

4. The leaves of Coxathus coxagus are infected with red spiders.

Rust spots on the leaves of coxagulus can be caused by two reasons. The first is due to fungal diseases, and the second is due to improper maintenance.

If it is a fungal disease that causes rust spots on the leaves of Coggyscar, it can be controlled by the following methods:

1.Clean up the diseased leaves in time to avoid the spread of the disease to other plants.

2.Spraying systemic fungicides, such as pyraclostrobin and azoxystrobin, can effectively control the development of diseases.

3.Strengthen maintenance, ensure that the plant growth environment is ventilated and dry, and avoid overwatering or fertilization to reduce the occurrence of diseases.

If it is a rust spot caused by improper maintenance, the following measures can be taken to improve it:

1.Adjust the maintenance method to avoid overwatering or fertilizing to ensure that the leaves of Coxatonus receive sufficient nutrients and water.

2.Prune the leaves of Coxatonus in time to keep the plant healthy and avoid the leaves being too dense, resulting in the occurrence of rust spots.

3.Strengthen environmental management, ensure the dryness and ventilation of the growth environment of Coxatonus leaves, and avoid growing in a humid environment for a long time, so as to reduce the occurrence of rust spots.

In short, for the problem of rust spots on the leaves of Coxathonus, it is necessary to start from the two aspects of maintenance and control, and take timely measures to ensure the healthy growth of the plant.

Coxagulus. Rust spots on the leaves are a common and serious disease of plants, mainly for the damage to leaves and stems, small light yellow spots appear on the leaves in the early stage, and small green spots are also born on the back of the leaves, and then a slightly raised blister is produced, and a large number of boxwood powders are emitted after the blisters are broken; Stem damage, often causing tumors, branches and rough skin, etc., fruit deformity or dehiscence. After the plant is infected with the disease, the growth is very weak, no flowering or a large number of flowers, resulting in no fruit, and in severe cases, the whole leaves of the whole plant from the bottom up turn black and dry, resulting in the death of plant roots.

1.Pay attention to maintain a properly dry and hail shed environment, in addition to ensure that the environment is ventilated, do not often leave water droplets on the leaves, and do not water the plants in the evening and night.

2.Remove rust-infected leaves and shoots and burn them together to avoid infecting other healthy leaves.

3.Add some acidic substances, such as ferrous sulphate or vinegar, to improve the pH of the soil when watering.

4.Regularly check the health source status of the leaves of Coxagulus, and find and ** infected leaves with pests and diseases in time.

Cause. There are two main reasons for leaves to turn yellow, one is improper fertilization, one is improper watering, and of course there are some other factors, but these two are the most basic and important reasons for leaves to turn yellow.

Resolution. Improper fertilization:

Let's start with the reasons for improper fertilization. The dependence on fertilizers is relatively high. If the long-term fertilization is insufficient, it will cause no nutrients to be absorbed by the plant, and the leaves will turn yellow; However, if there is too much fertilizer, it can hurt its roots and cause the leaves to turn yellow.

Improper fertilization can also affect its flowering or disappearance of the finger keys. Therefore, daily fertilization must be made according to the manual of fertilizer to make a reasonable ratio. Also, don't see that there is a problem with the plant and think that it lacks nutrients and can be fertilized blindly.

Improper watering: During cultivation, if the leaves wilt, it is a sign of lack of water. At this time, they should be watered in time and placed in a semi-cool place for maintenance.

They will recover slowly, but if not watered in time, the leaves will turn yellow over time. When watering, it is necessary to control the amount of water and do not accumulate water, which will make the soil lose its air permeability, affect the health of the plant, and the leaves will turn yellow. In the summer, watering can be done once a day, at 10 p.m.

If it is dry the next morning, you can water it properly.

Hello dear, <>

What is the reason for the blackening of the leaf edges of the coggylum, the answer is as follows: The reasons for the blackening of the leaf edges of the coxagulus may be as follows:1

Lack of light: Cochinus needs plenty of sunlight, and if it is not lit, it may cause the edges of the leaves to turn black. Please ensure that you receive at least 6 hours of sunlight per day.

2.Lack of moisture: Cochinus prefers a moist environment, and a lack of moisture can cause the edges of the leaves to turn black.

Make sure the soil is moist but don't overwater it to avoid root rot. 3.Pests and diseases:

Cochinus can be affected by pests and diseases, which can cause the edges of the leaves to turn black. Please check the coggylum regularly, and if you find any pests and diseases, you should take measures to prevent and control them in time. 4.

Nutrient deficiencies: Cochines need adequate nutrients, and if they are undernutrient, they may cause the edges of the leaves to turn black. Please fertilize the cochcoon regularly and choose a fertilizer suitable for the growth of the coggy.
