Sowing method of Petunia

Many flower friends consult the sowing method of petunia, hoping that the more detailed the better, the following flower friends have recorded the sowing process according to their own experience in planting petunia for many years, which is very helpful for flower friends.

Because Petunia grows rapidly, it is best to choose larger seedling trays or small flowerpots for sowing. I use 6*6cm seedling trays, which can always be planted with small seedlings.

Petunia: planting and maintenance methods of Petunia

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. Once there were many flower friends who asked: how to achieve one hole at a time? With a pair of sharp-beaked tweezers, you can easily pick up the pelleted seeds.

If it's an uncoated seed, it's easy to wet the toothpick with water and then put a seed in the nursery hole with a wet toothpick (no water).

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.

I judge whether or not to water on the basis of:

Look at the seedling hole topsoil becomes lighter, that is to say, the topsoil is dry and then watered. Look at the PP below. The red circle is freshly watered, and the color is obviously darker than the left and right ones.

Take my home as an example: in the north, there is heating inside, the balcony is closed, and the light is 5-6 hours a day. Put it in the house at night and bask in the sun on the balcony during the day. Because I used a large nursery hole with high 6cm and diameter 6cm, and the haze weather in Beijing for 7 consecutive days after sowing, there was almost no watering in the 10 days after sowing.

Dry long roots, wet long stems-this is a truth that I have remembered from the beginning of growing flowers.

4. Sunshine

After the seeds germinate, you can bask in the sun. At this time, you must bask in the sun more and water less. It is helpful for the seedlings to establish strong roots. The frequency of watering should be comprehensively considered according to different environment, season, as well as the size of seedling holes.

5. Fertilization

I do not advocate early fertilization, which can only encourage the seedlings and be counterproductive. Generally, from 3 to 4 weeks after emergence, sprinkle a few grains of mini green manure, the ratio of nitrogen, phosphorus and potassium of this slow-release fertilizer is 12-11-17, in addition, there are trace elements such as magnesium, which can promote rooting and prevent salt allergy of seedlings. When the seedling is a little bigger, it can be applied for ten and a half days and a half. Biwang diluted by 1RU 1000mm 1500.

Remember: apply thin fertilizer diligently.
