What if the spring feather leaves turn yellow? what if the spring feather leaves rot?

The yellowing, falling and decay of leaves are all common problems in the process of plant planting. Generally speaking, such problems mainly come from a certain part of the plant growth environment, so we need to eliminate and confirm the causes of the problems one by one, so as to solve the problems.

What if the spring feather leaves turn yellow?

1. Water yellow: it is mainly caused by improper water and fertilizer, and too much watering leads to the poor air permeability of the soil, which leads to the root rot of the spring feather plants. in this case, it is necessary to reduce the amount of irrigation and loosen the soil to enhance the soil air permeability.

2. Fat yellow: it is mainly caused by excessive amount of fertilizer. The old leaves turn yellow and fall off, but the new ones are thick and unstretched. In this case, top cabbage or radish seeds can be sprinkled on the plant and pulled out after emergence to consume excess nutrients.

3. Dry yellow: the lower leaves are dry yellow or shedding and aging due to long-term non-watering or plant dehydration. In this case, you can appropriately increase the amount of water and spray more water to meet the water needs of plants and keep the environment moist, or properly spray appropriate chemicals to replenish the necessary water for plants.

4. Alkali yellow: due to the acid-loving soil of spring feather and the alkalinity of water quality and soil in the north, the leaves faded and yellowed. In this case, fermented rice washing water or Rain Water should be watered.

What if the spring feather leaves rot?

If it has already rotted, if it is not serious, it can be pruned according to it. If there is too much water or improper fertilization, it needs to be replanted by changing the soil.

Be sure to choose soil that is both permeable and breathable before planting plants, so that even if you water too much occasionally, it will be easy to drain out.

Don't pour it in at once during daily watering, you can pour it slowly, and you can grasp the amount of water when watering to see how much water you put in, and the drain hole below will come out, and then make a record, so that you can compare the watering in the future. When the temperature drops to 15 degrees, watering must be controlled, when the plant's demand for water gradually weakens.

When fertilizing at ordinary times, we must pay attention to the concentration of fertilizer, dilute the thicker fertilizer, and slowly apply it along the edge of the basin.

Try to choose a place with good ventilation for maintenance.

What if Chunyu has diseases and insect pests?

1. Categories of spring feather diseases and insect pests

Generally speaking, plant diseases and insect pests are divided into diseases and insect pests.

The common diseases of spring feather include leaf spot, anthracnose and so on. Relatively speaking, leaf spot is more common than anthrax. The main manifestation of spring feather ring leaf spot is that there are nearly round leaf spots, brown to reddish brown, the edge is dark brown, the periphery is yellow halo, the spot faintly shows reddish brown wheel pattern, and needle size spots are gathered on the disease spot.

The common pests of spring feathers include red spiders and shell insects. Relatively speaking, shell insects are more common than red spiders, while the occurrence of red spiders is likely to be due to low air humidity, and the reason for shell insects is probably poor ventilation.

2. Treatment methods of spring feather diseases and insect pests

The diseases such as spring feather leaf spot and anthracnose can be controlled with wettable powders such as Dorinella, methyl topiramate, Dysen zinc and so on. Leaf spot is more common than anthrax. Specifically, leaf spot disease needs to be sprayed with 1000 times of 50% carbendazim.

Special insecticides can be sprayed to control the pests of spring feather red spiders and shell insects. Specifically, scale insects need to be sprayed with 1000 times of omethoate EC. In addition, to prevent red spiders need to increase air humidity, shell insects can be prevented by strengthening ventilation.

In addition, if the leaves are yellow, withered and scorched, they need to be pruned in time.

Cutting Propagation method of Spring Feather

Spring feather often uses the method of cutting propagation in sandy soil. The best breeding season is from May to September. To put it simply, it is to cut 2-3 nodes of strong stems and insert them into water moss or coarse sand to take root to keep the soil moist. It can take root in 20 days. Or cut off the upper plant of Chunyu for cutting, the lower part of the old plant will sprout a lot of buds, these buds can also be propagated.

In addition to the yellowing of leaves and the decay of leaves, diseases and insect pests are also an issue of great concern in the process of planting spring feathers. usually, a plant will infect other plants around it, and if it is not properly controlled, it may threaten all plants. therefore, we should achieve timely prevention and control and management.
