Petunia, Bidong eggplant, perennial herbs. The flower shape is very beautiful, the florescence is from April to defrost, the capsule and the seed are fine. It is distributed in South America and is now widely cultivated in many countries. So do you know what are the seed planting methods of petunia? How to apply fertilizer? How many years can you live?

I. seed planting method of Petunia

1. Sowing seeds

(1) put the seedling block into the box and soak it with water until it is all soaked. Pour out the excess water.

(2) dip the seed in water with a toothpick, put it in the middle of the seedling block, cover it, put it in the darker part of the balcony, open and ventilate for one or two hours a day, and then cover it. If the seedling block is slightly white, add water until it is filled with water and pour out the excess water. After a week or so, it sprouted.

(3) wait for two small buds to be put into another box, do not cover the lid, see the light, see the scattered light. I put the seedlings into the shade of mulberry flowers outside the balcony, well ventilated, seedling blocks to keep moist, lack of water to add water, do not accumulate water. Spray water once or twice a day, humidity is the most important, ventilation is the most important.

2. False planting

Use disposable paper cups or small flowerpots with a diameter of 8CM, drill holes with seedling soil and paper cups, and plant them together with seedling blocks, be sure to pour thoroughly and can be flooded. Put it in the sun, in the ventilated place, preferably outside the balcony, spray water every morning and evening. How to know the lack of water? as soon as you take the cup and feel lighter, you can water it thoroughly, pick it up again in two days, and then add water.

3. Colonization

(1) use pots above 20cm, remember, because the flowers are strong enough in the later stage.

(2) I usually use pebbles as drainage layer and mix it with 70% garden soil + flower soil + honeycomb cinder + perlite without applying base fertilizer.

(3) remove the whole seedling with soil completely, and the root can not be destroyed at all. Just tear off the cup with a disposable paper cup. 4. A day or two after the setting, put it in the shade, and then it will be completely in the sun. The more light, the better. 5, basically give fertilizer once every 10 days or so. I use leaf fertilizer and flushing fertilizer alternately. I have also used "Huaduoduo", potassium dihydrogen phosphate, and I have also used organic fertilizer made by myself retting bean dregs with water. It is very tasty, but fortunately, it will be tasteless in a day of ventilation.

4. Pre-flowering management

(1) cut off the branches that grow out of the basin. Remember that you must be willing to cut it off, only when it is cut off will it bloom into a bouquet.

(2) Light fertilizer is mostly applied in the early stage and phosphate fertilizer is applied in the later stage, so that the seedlings will be strong and the flowers will grow well in the later stage.

(3) if the balcony temperature is high, you can spray water appropriately every day to increase humidity.

5. Florescence management

(1) in the flowering room, fertilizer and water should also be adequately managed. I generally use the strong vine fertilizer or potassium dihydrogen phosphate used for growing vegetables in my hometown and apply it every 10 days and use it alternately.

(2) to ensure that there is plenty of sunshine, the more sunshine, the better the color of the flowers, the stronger the branches, the more flowers. On the contrary, weakness turns yellow, flowers are light and flowers are small.

2. How to apply fertilizer to petunia

1. Fertilization method

The main results are as follows: (1) if you want to make the petunia flowers more colorful and larger, fertilization should be carried out earlier, and it is recommended to start using them when they come out of the bud, and the effect will be more obvious.

(2) when applying fertilizer, we must pay attention to the concentration of fertilizer and apply more thin fertilizer so as to avoid the death of the plant caused by burning seedlings, and the root of the plant should be far away from the burial place of slow fertilization as far as possible.

(3) with the continuous decrease of air temperature in winter, the metabolic function of petunia will slow down, and very little water and fertilizer are needed, so fertilizer can be applied according to the actual growth of petunias.

2. What fertilizer should be applied?

(1) the most important thing to fertilize petunia is to pay attention to not partial fertilizer, heavy fertilizer, you can apply nitrogen fertilizer such as urea to cattle.

(2) fertilizers such as potassium dihydrogen phosphate can be applied frequently during flowering, which can make the flowers bloom more vigorously.

(3) if the flower of petunia becomes smaller, it may be caused by too little fertilization, and phosphate fertilizer should be applied to improve it.

(4) in addition, peat and coconut bran can also be used in planting. The amount of base fertilizer should be sufficient, slow-release fertilizer and chicken manure can be used. It should be noted that home-made manure is not recommended for use in the home. This fertilizer smells unbearable and attracts insects easily.

How many years can Petunia live?

Although petunias are in season and bloom only one season, they can live for several years if they are taken care of carefully. When the flowers fail, you take off the remnants and trim the note so that the plants will flourish and survive when they sprout again. Also, its seeds can continue to sprout and blossom when they fall into the soil. By the way, the petunia should not be too wet or too dry. Usually pay attention to watering. If you transplant it from the flowerpot to the soil, it will grow more luxuriantly.
