1. Peak growth season

Although Qionghua is not picky about its growth environment, this does not mean that its growth rate has been maintained in the same line. Like all flowers, Qionghua can grow very fast only at a specific time, but when we are happy with its growth, we can not forget that pests and diseases are actually the most dangerous creatures at this time. If we often use fertilizer for it and the amount of fertilizer is not much each time, If the leaves are still yellow at this time, we should understand that it is the diseases and insect pests that make the leaves not nutritious. At this time, we should take measures to treat diseases and insect pests. Generally speaking, we will choose ferrous sulfate solution. Spraying this solution on the leaves can effectively kill hateful diseases and insect pests, but we must pay attention to the proportion of the solution. If too much or too little is not good, we must see that we need to use one thousandth of the solution

2. Plum rain season

In fact, Qionghua itself was very vulnerable to insects at that time. This is because it has a very good characteristic, that is, its leaves actually have a lot of fur, so the pests and diseases can not hurt its root. However, although it has a strong defense function, its lower epidermis is its weakness. The degree of keratosis here is not high, so some pests and diseases take advantage of this characteristic, and they can secrete some substances, These substances can just dissolve this thin layer of cutin, which provides a great possibility for the invasion of diseases and pests. This usually happens in the rainy season, so we have to pay attention to it when it comes to the rainy season and take good measures to protect Qionghua. Our measure is generally to spray pesticides, which are commonly used insecticidal substances, so we don't have to worry about being difficult to buy. Its name is Bordeaux liquid
