Planting method of Petunia

Petunia can be said to be the king of grass flowers. Petunia is almost a must for flower friends. Indeed, petunia is a good kind of plant that is easy to produce results. It not only has a full range of flowers and colors, but also has a large number of flowers, blossoms constantly, and is not afraid of cold or heat. The planting method of petunia is actually very simple, please take a look:

Sowing: this autumn sowing mixed with light waves, 5 out of 4, bel canto ice lilac 5 out of 4. When sowing soil with carbon mud, perlite and vermiculite can be added properly to increase air permeability, otherwise the water retention of carbon mud is too good and it is easy to cover the seedlings with yellow. Dwarf cattle need light to germinate. Just put them on the south-facing windowsill where they will not be exposed to direct sunlight at noon. Remember that there should be enough water in the nursery box to maintain 100% humidity.

Before planting petunia, flower lovers need to know its growth habits. Petunia prefer warm, sufficient light, moist soil and other links, it is not cold-resistant, not resistant to water and moisture, not resistant to drought, so we should pay attention to reasonable watering, but also ensure that the soil is more fertile, let's understand its conservation skills.

Planting method of Petunia

What kind of soil does Petunia use

1. Garden soil + peat soil: because petunia likes rich and loose soil, we can mix it with half of garden soil and peat soil, and we can also add some organic fertilizer to it to improve its nutrient content.

2. Peat soil + rotten leaf soil + vermiculite: rotten leaf soil is one of the soils that many plants like, but in order to ensure that the soil is more loose, you can add some vermiculite, the proportion of which is 40%, 40%, 20%. If you want to add base fertilizer, you can add some bone powder.

3. Rice chaff ash + peat soil: the ratio of the two is 2:1, you can also add some compound fertilizer or bean cake powder, stir them well before use, in which rice bran ash can be replaced by garden soil. The soil had better be soaked with carbendazim and potassium permanganate solution before use, which can prevent and control diseases and insect pests.

Second, lighting conditions

Petunia prefer sunny environment, but need sunshade in summer, so how to grow petunia in terms of light? The answer is to ensure plenty of sunshine in spring, autumn and winter, with at least 12 hours of sunshine a day, and avoid excessive sunlight in summer.

3. Suitable temperature

In the planting method of petunia, the most suitable temperature is 13-18 degrees. In winter, the temperature should be kept at 4-10 degrees. If it is lower than 4 degrees, its growth will stop, and long-term low temperature may cause freezing damage to the plant. In terms of high temperature, petunia can withstand a high temperature of more than 35 degrees, but try to avoid long-term high temperature in the planting process.

Fourth, watering method

When the petunia is growing vigorously, it is necessary to ensure adequate moisture, water should be watered in the morning and evening in summer, and drainage and waterlogging should be done during the rainy season. If the soil is often too moist, it may make the branches and leaves grow steeply, and the flowers are easy to wither and fade early, so make sure the soil is not too dry or too wet.

5. Methods of reproduction

Petunia is commonly used in two propagation methods, namely cutting and sowing, in which cutting uses robust branches as cuttings, which are carried out in spring or autumn. Sowing requires relatively full and mature seeds, and the germination time is generally about 2 months. under normal circumstances, it takes about 100 days from sowing to flowering.

VI. Pest control

Petunia is vulnerable to diseases and insect pests such as white mildew, aphids and so on. If white spots are found on leaves and leaves fall off early, it is necessary to spray chlorothalonil and other drugs in time. The control method of aphids is to kill with omethoate emulsion.

Matters needing attention for Petunia overwintering

1. Heat preservation and moisturizing: as mentioned earlier, the growth of petunia will be inhibited when the temperature is lower than 4 degrees, but in order to let it go into dormancy smoothly, it is necessary to keep the temperature too high and keep it warm in winter. 4-10 degrees is more appropriate, at the same time to ensure that the humidity is moderate, not too dry.

2. Removal of dead leaves: after the temperature begins to drop, some old leaves on the petunia plant will wither and yellow, and they can be removed before it falls off naturally, which can control diseases and insect pests and make the petunia plant beautiful in winter. it can still play its ornamental value in winter.

The planting method of petunia can be said to be the king of grass flowers. Petunia is almost a variety that must be planted by flower friends. indeed, petunia is a good species and easy to produce results, not only with complete flowers and colors, but also with a large number of flowers and continuous flowering. Not afraid of cold and heat, the planting method of petunia is actually very simple, please see: sowing: this autumn sowed light waves mixed color, 5 out 4, bel canto ice lilac 5 out 4. Using soil to sow soil with carbon mud, you can appropriately add a little perlite and vermiculite to increase air permeability, otherwise the water retention of carbon mud is too good, it is easy to cover the seedlings yellow. Dwarf cattle need light to germinate. Just put them on the south-facing windowsill where they will not be exposed to direct sunlight at noon. Remember that there should be enough water in the nursery box to maintain 100% humidity. Fertilization: petunia likes fertilizer, and there is a big difference between using fertilizer or not. My experience is that after 4 true leaves are produced, to the stage of pseudo-planting (the small grid of the nursery box is full of roots), 2000 times of Biwang is fertilized once a week. From pseudo-planting to colonization stage, 1500 times of Biwang is fertilized once a week, and a little slow-release fertilizer can be added appropriately when pseudo-planting. When planting to the full stage, Biwang was fertilized 1000 to 1500 times twice a week (the concentration increased with the plant size). Add sufficient base fertilizer when planting. When the bud is in full bloom, Biwang will blossom 1000 times and apply fertilizer twice a week. Sometimes dwarfs are short of iron, so you can add some ferrous sulfate. Hit the top and use the basin: to become a bouquet, you must hit the top! As for how to fight, in the words of the cat, it is: cut it along the edge of the basin! Don't be soft, don't be distressed, click decisively! Do not want to give up the child can not bear the wolf, the specific implementation of the top or to see the cat God paste, I think I have not yet completely started. Do you use a pot? it's always right to 20cm-25cm one pot at a time. Watering and sunshine: dwarf cows like to drink water, and when they are full, they are not afraid of the sun! But remember to bask in the sun! If you don't get enough sun, you will test your topping skills if you want to become a bouquet. When you sow in autumn, the four true leaves of the dwarf can be illuminated all day long, and the premise is still enough water. My practice is to throw it directly on the terrace from the very beginning of germination, but after all, the temperature in autumn is not high, and there is enough water in the bottom box of the nursery box. Recommended varieties: light wave white and purplish red, not light wave blue purple! Bel canto ice lilac design is really beautiful, but bel canto likes horizontal long, easy to pan, but the effect of two trees is still good (diameter 34cm semicircle wall hanging basin, see picture). Medication: dwarf cattle grow whitefly and leaf miner, just use some flower protection. Conclusion: this autumn sowing, the cultivation of dwarf cattle is not very successful, a total of 7 pots of cattle, the ball is only four pots, and the breed has something to do with technology, in any case, we should remember to plant dwarf beard big pot, big water, + big fertilizer (thin fertilizer frequently), dare to cut, dare to bask in = ruthless ~! The most important thing: take a look at the god stickers of cats!
