How to breed petunia and what to pay attention to when breeding

Petunia breeding method

The common methods of petunia propagation are cuttings and sowing. The most commonly used method is sowing, which is usually carried out in May-June and around October each year. The temperature at this time is above 20 degrees, which is suitable for petunia rooting and later recovery.

Common breeding methods for petunias

1. Petunia cutting propagation

Petunia is suitable for cutting propagation in May and June and August and September. This is the growth period of petunia, and the temperature is relatively suitable, so the probability of survival is high. Disinfect the soil in the pot and wet it with water. There should be no stagnant water.

Cut off healthy branches, about 10 cm in length, preferably leaving three small leaves, and then insert them into the soil at a depth of one to two centimeters. Place them in a cool and well-ventilated place. Roots will grow after about half a month, and they can be moved out for planting in about a month.

2. Petunia seed propagation

Petunias are generally propagated by sowing in June, July, and October to November. First, prepare loose and fertile soil, mix the soil rich in rotten leaves and sandy soil, disinfect it, and wet it with water. After sowing the seeds, cover them with a thin layer of soil and press them lightly. Wait for about twenty days for the sprouts to grow.
