1、 Is autumn maintenance important

For Petunia, the maintenance method in autumn is more important. Because this period is a period when the temperature decreases slowly, the climate changes in all aspects are relatively intense, and the maintenance methods before and after will change greatly, so the requirements for maintenance are high. In addition, although its main flowering period is in summer, it may also bloom in winter, so the maintenance in autumn is more important, because it is necessary to accumulate enough nutrients for flowering, otherwise it will not be able to bloom in winter

2、 How to maintain

1. Temperature: temperature is very important, because the change of temperature is most obvious in autumn. The most suitable is 13 to 18 degrees. In the early autumn, the temperature may still be relatively high, while in the later stage, the temperature will be lower than the price, and there is a risk of freezing injury. Therefore, the maintenance before and after is very different, which must be adjusted according to the specific situation

2. Light: light is more like temperature. The light is strong in the early autumn, and then it will slowly weaken. Therefore, while avoiding too strong light, provide appropriate light and accumulate enough nutrients for flowering in winter

3. Ventilation: proper ventilation can reduce the occurrence of diseases and pests

4. Pruning and fattening: its flowering period is mainly in summer, so the residual flowers must be cut off in autumn, and the flower branches can be cut off together to promote the next flowering. In addition, after pruning, an appropriate amount of fertilizer should be added
