1、 How to deal with the newly bought Petunia

When you first buy Petunia, don't put it in the pot directly. You need to check the state of the plant first. If it is a seedling, you can let it adapt to a warm and humid environment for a while. When it grows more than two or three real leaves, the root will almost grow well, and then you can put it in the pot. For larger seedlings, you need to check whether the branches and leaves of the plant are dry and yellow. If so, you need to trim them together, and then put them in the pot

2、 How to breed Petunia just bought

1. Soil: when changing pots for Petunia seedlings, it's best to apply a thin layer of fertilizer at the bottom of the basin. Don't peel off all the original soil. If the original soil is not good, you can shoot some properly. Be careful not to hurt the roots. Other places should be filled with soft soil. It's best to choose loose, fertile and well drained new soil

2. Temperature: it is suitable for growing in a warm environment. It is best to provide it with a growth environment of about 20 ℃ and good ventilation. During the high temperature period in summer, it can be properly shaded and watered to reduce the temperature. In winter, in order to make it safe to spend the winter, the temperature should be kept above 5 ℃

3. Watering: it can't be watered too much after it's just bought. Water it properly and don't let the soil dry. After it returns to normal growth, follow the principle of "dry and pour immediately, pour thoroughly" to water it, so as to keep the soil slightly wet but not ponding. In summer, you can often spray water around it, which can increase the humidity of the air and is more conducive to its growth

4. Light: it likes light, but when it was first bought back, because it did not adapt to the new environment, it needs to be placed in a place with scattered light for maintenance. It can not be placed directly in the sun to prevent flowers and leaves from being burned. After it returns to its normal growth state, it needs to be given sufficient light. When the light is strong in summer and autumn, it can be properly shaded to avoid plant damage

5. Fertilization: when you buy it back, you don't have to fertilize it. Because it is still in the slow basin stage at this time, fertilization is easy to lead to root burning. After a period of time, it can be fertilized after it adapts to the new environment. Fertilizer with high content of nitrogen and potassium and appropriate low content of phosphorus can be selected for fertilization
