1、 Basin blasting method

1. The soil with good drainage and air permeability shall be selected, and it shall be acidic. Soil rich in humus and sandy soil can be selected

2. Sow at the right time. If there is a race of Petunia, it will be found that if sown in autumn, the branches will be more compact, while if sown in spring, the branches will be less compact. Autumn sowing should be between October and November, but due to regional differences, it can be adjusted appropriately

3. We should replace the flowerpot in time, because Petunia is growing up, so we should replace the flowerpot in time, so as not to hinder its growth

4. In the seedling stage, topping shall be carried out. The so-called topping is to pinch off the leaves on the top. When the number of branch leaves is more than five, the buds on the top can be removed, leaving three to five leaves. In addition to topping, you can also properly trim the leaves and cut off some large leaves that block the light below, which will balance the sunlight of all parts

5. Fertilizer should be applied frequently. Petunia needs a large amount of fertilizer. Liquid fertilizer should be applied every ten days during the growth period

2、 Precautions

1. Petunias like a humid environment. To maintain moisture, they can often spray water

2. Pay attention to the prevention and control of pests. When raising in the house in winter, you will be vulnerable to aphids and scale insects. At this time, you can't spray pesticides directly, which will harm the plant. Wipe off the insects with a rag and disinfect the petunia. Put it in a ventilated place to reduce the harm of insects< span>
