Matters needing attention in planting Artemisia annua

There were many people who planted vegetables like chrysanthemum, but they encountered many problems. In fact, the technical requirements for planting chrysanthemum are not high, but some problems are not simple to solve. What problems should we pay attention to when planting chrysanthemum? These are the ones everyone should pay attention to.

1. Early weeding

The early stage of chrysanthemum seedlings is not only shallow root system, but also easy to be robbed of nutrients by weeds, so early weeding is one of the problems that everyone should pay attention to. When the grass in the chrysanthemum field is relatively large, it is basically difficult to grow chrysanthemum. This either did not use herbicides before planting, or after planting to clean up, there must be no more weeds around the seedlings, mainly around the seedlings to clean up.

2. Medium-term water control

At the middle stage, chrysanthemum itself has a certain ability to protect itself. At this time, ordinary weeds basically have no threat to it. However, this stage is a prosperous and long stage, and the demand for water begins to rise, so the focus at this time is on water control, and how to meet the water growth of chrysanthemum should be considered. At this stage, it is necessary to observe the growth of chrysanthemum after each watering, and the time is about once every 3-5 days, so as to ensure its growth.

3. Disease prevention

As the boom season approaches, diseases naturally increase because the contact area becomes larger. Such as downy mildew is relatively common, we need to make some targeted adjustments to prevent diseases. The source of chrysanthemum disease is soil, so the disinfection of soil and chrysanthemum itself are the two key points. We can use some drugs to prevent it.

4. Low temperature protection

Low temperature is the enemy of vegetables, and chrysanthemum is more difficult to resist the existence of low temperature, so planting must pay attention to low temperature prevention. Below 5℃, chrysanthemum basically will not grow, even dangerous, when below zero may appear a large number of deaths, so in all kinds of low temperature days we should take good cold measures, such as some mulch and the like we had better use in time, so as not to appear loss.

These are some of the problems that need to be paid attention to when planting chrysanthemum. I hope everyone will pay attention to them. Vegetables themselves are relatively fragile. If you want high yields, you basically have to manage them well.
