How to wither the leaves of Dryopteris Dryopteris? the treatment method of blackening the long spores on the back of the leaves of Dryopteris

Dryopteris Dryopteris is a kind of plant which likes temperature and is not tolerant to strong light, and it is distributed in many parts of our country. It is now a popular domestic plant, but if it is mismanaged during breeding, it can cause leaves to wither or blacken.

What about the withered leaves of Dryopteris?

1. When raising clematis, it is generally best to put them in places where the indoor light is relatively weak. However, in the more exuberant growth season, it is better to give sufficient scattered light.

2, pay attention to, in the daily maintenance process, the soil should be moisturized, so watering must be adequate. In dry weather, water should also be sprinkled on the leaves of Dryopteris to increase the humidity of the air.

3. If there is a blight, you can first control the water, or switch to hydroponic culture. In the usual maintenance, we should control the amount of watering, you can spray more water to maintain air humidity. For the dried leaves, it is best to cut them off.

Treatment of blackening of long spores on the back of Dryopteris leaves

The main results are as follows: 1. The reason of blackening: the plant grows slowly in winter and the nutrients of the leaves are insufficient. If the temperature is low and the leaves are frostbitten, the leaves will gradually blacken. The environment is shaded and impenetrable, and iron ferns like to be overcast. Many families will put it in the living room and bedroom for maintenance. It is inevitable that there is some poor ventilation. If the light is insufficient for a long time and the air is not convective, the leaves will turn black. Lack of fertilizer and water, Dryopteris likes fertilizer, if there is no fertilization for a long time, the wet potted soil will make the plant leaves wilt and gradually turn black.

2. Prevention and control methods: the temperature is low in winter, so it is easy to suffer frost injury. In addition, the light is weak in winter, many families will move the fern to the sunny balcony, but it is easy to freeze when the window is opened sooner or later. So control the indoor temperature, especially in the morning and evening, and don't put it by the window. Dryopteris does not like the muggy environment, especially in summer, which requires regular ventilation, increase air humidity and replenish light properly. Dryopteris prefers sandy loam rich in humus and needs plenty of fertility. Before planting, an appropriate amount of brick shavings or lime particles can be added to the soil to enhance calcium and improve soil permeability. In addition, fertilizing once a month in peacetime maintenance, focusing on calcium supplement.

The cause of the withering of the leaves of Dryopteris

1. The light is strong. Dryopteris itself is a plant that likes a semi-shady growing environment and is more afraid of direct sunlight. If the light is too strong, it will cause the water on the leaves to evaporate quickly and cause the leaves to wither.

2. Lack of water. Dryopteris likes to grow in a relatively humid environment. The soil should be kept moist and the air humidity should be kept at a high level when raising Dryopteris. If it is not watered enough, the water will be insufficient, which will often lead to the withering of the leaves of the fern.

3. Stagnant water. The leaves of Dryopteris will dry, and stagnant water is also an important factor. Because most plants do not like stagnant water, stagnant water will cause too many problems, such as rotten roots, yellowing leaves and so on. Although Dryopteris is a plant that likes a humid environment, if it is watered too much, it will be timely, causing the leaves to wither.

What about the scorched edge of the leaves of Dryopteris Dryopteris?

1. The leaves of Dryopteris Dryopteris have brown scorched edges, which is a common problem encountered in cultivation. Mainly because of improper maintenance environment, too strong sun, lack of water, the lack of water in the leaves will make some cells dry and dehydrated, the green will gradually fade, and then the focal edge will appear.

2. Immediately move the fern to the semi-shaded place for maintenance. If the fern is placed on the balcony, it is recommended to move the flowerpot to the bright place indoors, which will gradually ease in a few days. Take good care of it in the next few days and try to avoid being stimulated by bright light again. Cut off the charred leaves in time and spray water on and around the leaves to increase air humidity.

The withering or blackening of Dryopteris leaves is usually caused by fertilizer, water or temperature problems. You can carefully observe and find out the cause, and then solve the problem from the root. There are some specific solutions described above, which I hope will be helpful to you.
