How to Keep Petunias Blooming in Winter

If you want petunias to bloom in winter, there are two main points: one is pruning and the other is temperature.

Insulation

Generally, the flowering period of petunias is adjusted with the sowing time. If you want petunias to bloom in winter, you can sow them in early autumn, because it takes about 2 or 3 months from sowing to flowering of petunias. If the temperature can be guaranteed, petunias may be able to bloom in winter. Sow petunias in early autumn, and then ensure appropriate light and temperature, as well as the application of water and fertilizer.

prune

Another method is to prune, because in winter, petunias cannot withstand the cold outdoors and need to be brought indoors, usually around October. Before bringing the petunia indoors, prune it. Heavy pruning is generally better. Prune the branches of the entire plant significantly, leaving 2-3 buds on each branch. When the retained buds sprout, you can repot them, remove about one-third of the old soil, trim the roots, and then repot them. Note that although you are pruning hard, don't do it too hard.

Key points for caring for petunias in winter

Since you want petunias to bloom in winter, winter maintenance work is also very important.

Petunia is not tolerant to low temperatures. The temperature must be kept above 4°C in winter, otherwise the plant may freeze to death. In addition, it is also necessary to ensure that the petunia can get sufficient light in winter. It is best to place it in a window sill or other place, and pay attention to ventilation. It is best to open the windows frequently for ventilation.

Only with proper winter care can petunias grow healthily and bloom.
