How can you make petunias bloom in winter?

In the winter in the north, there is heating in the rooms, and when the heating is on, the temperature can reach 18 to 25 degrees, which is the most suitable temperature for the growth of petunias.

Petunia is a flower that loves sunlight very much. If there is no light, the petunia will not bloom even if the temperature is high. Therefore, if you want the petunia to bloom, it needs sufficient sunlight. We can place the petunia on a sunny balcony, so that even in winter, the petunia will bloom well.

The planting soil should be fertile and loose, with not too much water. You can water it when it is dry. When the temperature is high in summer, just provide slight shade, but not complete shade. Leave a little sunlight, and pinch and top it more often so that it can grow more side buds and branches, and it will bloom more.

When is the best time to prune petunias?

The pruning time of petunias has always been the focus of discussion. It is reported that petunias should be pruned after they have bloomed. Prune the remaining flowers in time to save nutrients for the plant. The remaining flowers are the flowers that have bloomed and faded. They do not need to consume nutrients from the plant. What consumes nutrients is the receptacle behind the flowers, that is, the ovary of the flower. Whether it is pollinated or not, the ovary is the fruit of the petunia. The fruit expands and grows, which requires a lot of nutrients from the plant. Therefore, when we prune the remaining flowers, the most important thing is to prune the ovary behind the flowers.

What are the methods of propagating petunias?

There are two ways to propagate dwarf cattle, sowing seeds or buying seedlings. Those who are confident in sowing can try sowing seeds. There are relatively many varieties of dwarf cattle seedlings bought online. You can sow them in a seedling box, and they usually take root in about a week. Buying seedlings is simple, just plant them directly and put them in a cool place for three to five days to slow down the growth.
