1、 Breeding method

1. Sow and reproduce. The time is generally selected in June and July and October to November, when the climatic conditions are more suitable. The best temperature is 20 degrees. First prepare the soil, mix the soil rich in rotten leaves with sand, and disinfect it. Wet through with water. After sowing the seeds, cover them with a thin layer of soil and press them gently. Wait for about twenty days and you can sprout

2. Cutting propagation. May, June and August and September are more suitable. This is the growth period of Petunia, and the temperature is more appropriate, and the probability of survival is high. Disinfect the soil in the basin and wet it with water without ponding. Cut off about ten centimeters of healthy branches. It's best to leave three small leaves, and then insert it into the soil. Don't go too deep, just one to two centimeters. Put it in a cool and well ventilated place. Roots can grow in about 15 days and can be moved out and planted in about a month

2、 Precautions

1. The ability of small seedlings to resist cold after breeding is relatively poor. It should be noted that the temperature should not be too low, about 27 degrees is the best, and it should not be less than 15 degrees at night

2. The soil should be loose and breathable, otherwise it will reduce the probability of survival

3. Petunias continue to grow. When they grow to a certain extent, they should be planted and moved to a larger flowerpot. Move the flowers out with the soil, which is good for survival. And it should be planted more than two months before the flowering period, otherwise it will affect the flowering
