Breeding methods of Petunia in Spring and Autumn several techniques of blooming in summer

Petunia is a very popular and popular summer flowering plant, properly protected and able to keep blooming continuously until the advent of frost, it has a very rich variety and color, and the decoration is very good. Petunia is suitable for potted plants or as hanging pots for maintenance.

Petunia has single and double petals, some mixed-color varieties, and even some fragrant varieties. Beginners had better raise some petunia varieties with strong resistance to diseases and insect pests to avoid excessive moisture in summer. otherwise, it is easy to be infected with fungal diseases.

The cultivation of petunia should give as much light as possible, but when the Summer Solstice is hot and the light is too strong, he should be properly shaded to avoid excessive exposure.

Petunia can grow well in fertile, loose and well-drained soil, and it is best to choose compost soil or manure soil rich in humus and high fertility. Some slow-acting organic fertilizer can be added to the bottom of the plate and sand is added appropriately to maintain the good drainage of the soil.

Petunia is very suitable for sowing in spring, after the temperature is stable, the best sowing temperature is between 18 and 25 degrees. You can choose a smaller seedling pot to cultivate, and then transplant after the plants grow bigger. The growth temperature of seedlings should not be too high. It is most suitable to sow seeds at about 15 degrees Celsius. After the seedlings grow up, slowly increase the light, be sure to wait until the frost is completely over before sowing.

Where the temperature is colder, you can choose to sow seeds in May or June, and you can add some mature organic fertilizer as base fertilizer in the basin, which is beneficial to promote the growth of petunia and cultivate the soil of Petunia. You can choose to mix compost soil with peat soil and add 2 to 3 parts of sand appropriately.

Petunia is very suitable for hanging basin maintenance, can also be used as a pot, in places with good drainage, but also can choose to plant maintenance.

When the summer temperature is high, it is necessary to regularly water the soil to avoid excessive drought and keep the soil moist during the growing period, but to avoid stagnant water, keep the soil moist, and not be too moist, too much moisture can easily lead to the growth of branches and leaves. The number of flowers will also be reduced.

Petunia should be fertilized regularly in the growth process, so as to promote continuous flowering, it is best to give some fertilizers with higher phosphorus and potassium content, which can maintain a longer flowering period until the frost comes at the end of autumn.

When you see petunia's flowers withering or falling off the line, you should pick off the camellias in time to avoid its fruit and preserve more nutrients and promote secondary flowering.

After the flowers wither, they can also be supplemented with appropriate organic liquid fertilizer to promote the growth of branches and leaves and give birth to more buds.

The overwintering maintenance of petunia is also very important. after the weather gets cold at the weekend, the potted petunia should be moved to indoor maintenance knowledge in time, some withered and damaged branches and leaves should be cut off, and it can be transplanted into a larger flowerpot. The bottom of the pot can be added with appropriate mature compost, put in a warm place to survive the winter, and the root system should be avoided in the process of changing the pot.

Petunia reproduction is also very simple, you can choose to carry out branch cutting propagation in the spring and autumn season, you can select some relatively robust branches that do not bloom, and the cut branches are about 8 to 10 centimeters long and can be obliquely cut from the bottom of the growing point. all the leaves at the bottom of the branch, 2x3, should be cut off.

Prepare to loosen the drained soil, keep the soil moist, cut 5 or 6 petunia branches in the basin soil, put them in a place with bright light and good ventilation, first avoid direct sunlight, wait two or three weeks and then slowly increase the light time, petunia maintenance can also cultivate the cutting seedlings independently.
