Seed price and planting method of petunia

Petunia is a funnel-shaped, colorful ornamental flower, especially suitable for planting in flower beds, courtyards and other landscaping, planted all over the world. There are many varieties of petunia, and seed reproduction is generally adopted. What is the seed price and planting method of Petunia?

Seed price of Petunia

There are many kinds of petunia, and their shapes are different, and their flower color, size and plant height are different, so the seed price of petunia is not fixed. It depends on what kind of petunia seeds are usually several hundred yuan per jin.

II. Seed planting methods of Petunia

The seeds of petunia are so small that they can be sown on a burrow plate in principle. But the blue demon advises everyone not to use the acupoint plate, because the acupoint plate is integrated, and if it is not sprouted neatly, it will bring some difficulty to the management.

1. Colonization

Petunia soaks the sowing soil before sowing (don't make the sowing soil very wet. "soaking and soaking" is appropriate to hold water). When sowing, you must sow one seed at a time to avoid damaging the roots of the seedlings in the future.

If it is an uncoated seed, first wet the toothpick with water, and then dip a seed with a wet toothpick (no water) and put it in the nursery hole.

After the pelleted seeds are placed on the surface of the cave soil, drop a few drops of water with an eyedropper (just point two or three drops of water, do not use a spray can, use an eyedropper), and the coating can be melted, so that it can germinate earlier and ensure the germination rate. Petunia is sown without covering the soil and can be covered. It needs to be opened for an hour a day to breathe.

2. Spray water

Before germination, spray water every day to ensure a certain amount of humidity, which is conducive to seed germination. Use a small spray can to spray water, and the water column should be fine to avoid washing away the seeds. The soil in the nursery hole should not be overfilled. If it grows in vain, you can cultivate the soil again to prevent lodging.

3. Watering

If you want to harvest the bouquet in the future, you must first make the seedlings strong, so the management of the seedling stage is very important. We know that the roots, stems and leaves of plants are vegetative organs, which have the functions of absorption, storage, dredging and assimilation respectively, and whether the seedling is strong or not depends on whether its root system is developed or not.

4. Lighting

Petunia like the environment with sufficient light, no matter potted or planted on the ground, they should receive sufficient light to ensure that direct sunlight for more than 6 hours a day can effectively promote the growth and flower bud differentiation of petunia. Potted friends should pay attention to the fact that summer light will raise the temperature in the basin and accelerate water evaporation, resulting in a lack of water, which should be watered once in the morning and evening to ensure sufficient water.

5. Pest control

Petunia is easy to be infected by fungal diseases, and the common diseases are white mildew, leaf spot, virus and so on, which requires that the soil should be fully disinfected before seed sowing, even if the diseased leaves should be removed to prevent the spread of the disease, and even if chlorothalonil is sprayed. Dysenammonium and other fungicides. Virus disease is a semi-life disease of aphids, which is caused by wound infection on the plant after the aphids ingest the juice. Therefore, the prevention of viral diseases is carried out at the same time as the elimination of aphids. Insecticides such as imidacloprid and omethoate are generally used to kill.
