1、 Survival time

Normally, it can survive for one to two years. However, due to different planting methods, growth environment, culture methods and other conditions, the survival time of Petunia is often different. Some only survive for a few months and die; Some live longer and can live for a year; Others can live for two years; Others can survive four to five years, or even longer. In fact, as long as we master various planting conditions, we can prolong the survival time of Petunia. If the temperature, light, moisture, fertilizer and pruning can be reasonably controlled, the survival time of Petunia will be greatly prolonged and can survive for a year or two or even longer. However, if it survives for too long, all parts will age, and the plant will become unhealthy, dry and soft. And the flowers will be less and less, and even will not bloom in the end. Therefore, generally speaking, Petunia can be raised for one or two years. When it blooms, its seeds can be collected for the next batch of planting

2、 Precautions

1. Pay attention to daily pruning and fertilization

2. We should make full preparations for the wintering of Petunia to make it live through the winter safely. It should be put indoors in winter, and it will grow very slowly when the temperature is lower than four degrees. Close to stagnation, so pay attention to the temperature

3. Provide plenty of sunshine and good ventilation

4. If you only raise it for one year, you should "pick the heart" at the seedling stage. After two to three times of "picking the heart", you can make Petunia blossom and burst into pots
