Rosemary wilt. What's going on?

Rosemary is a shrub plant that likes to grow in a warm environment and originates in Europe. Rosemary is mainly used in flowers and leaves, because flowers and leaves contain antioxidants, which has a very high use value in medicine and other industries. However, when we plant rosemary, we often find that rosemary withered, so what is the cause of this? Let's introduce it to you by the editor.

1. Poor ventilation

The growing environment of rosemary is relatively warm and should be ventilated to some extent. We must do a good job of ventilation when we plant rosemary. If rosemary has a sultry and poorly ventilated place for a long time. It will hinder the growth of rosemary plants and reduce the growth rate of rosemary. And if accompanied by high temperature conditions, the degree of impact will be even higher. High temperature will inhibit the respiration and photosynthesis of rosemary, resulting in insufficient accumulation of nutrients. If it is not treated in time, it will lead to the drying and death of the whole plant of rosemary.

2. Lack of light

Light is very important for the growth of rosemary, and rosemary has a large demand for light in the growth process. When we plant, we should keep light for at least six hours a day. If the light demand of rosemary is not met, then the photosynthesis of rosemary is insufficient, the amount of chlorophyll is decreased, and the photosynthetic matter is not enough. It will not only lead to gradual yellowing and withering of leaves, but also lead to lack of nutrition in the growth of rosemary. If you do not deal with the lack of light for a long time, the wilt phenomenon will be more serious, and even cause a variety of diseases and insect pests.

3. Improper moisture

The origin of rosemary is in Europe, and the demand for water in the growth process is not very large. Drought tolerance is relatively strong, so we must pay attention to control the amount of water when planting. If there is too much water, the stagnant water will affect the respiration of rosemary roots, cause root rot, cause diseases and insect pests, cause rosemary can not absorb nutrients normally, and seriously affect the growth of rosemary. It led to the phenomenon of leaf wilting gradually. If too much watering, then timely drainage, drying the soil, and then planting.

4. Diseases and insect pests

Diseases and insect pests are the main causes of rosemary wilt. There are many common diseases and insect pests of rosemary, which will harm various parts of rosemary in varying degrees. When planting, we should strengthen management, do a good job in light, temperature and humidity, and give priority to prevention. Then we have to disinfect regularly to reduce the base number of pathogens. Often observe the growth of rosemary, when there is an abnormal situation, first check what are specific diseases and insect pests, and then carry out symptomatic treatment to avoid the spread of the disease and expand the affected area.

This is a brief introduction to what happened to rosemary wilt. Rosemary often encounters some problems in the process of planting, but most of them are caused by our poor management. Therefore, we must pay more attention. That's all for today's introduction. This article is for reference only. Thank you for your reading and support.
