The preparation work mainly includes: seed washing, flower pot and flower soil selection.
The first time we plant Petunia, we need to choose the right seeds, but if there are Petunia friends who can give us ready-made quality, it is better. Petunia seeds are very small, so the sowing needs to be very fine, we suggest that you buy better quality seeds. If the seeds can not be sown at a time, they can be wrapped with the original packaging + newspaper, and stored in the refrigerator freezer for later use.
It is recommended to use a 20cm pot for the potting of Petunia, because there is a large growth space in the later stage of Petunia.
Petunia is not very picky about flower soil. It's better to choose loose, fertile, and good drainage micro acid sandy soil. If you don't want to buy the matching flower soil from the flower market, you can also try to make the culture soil of Petunia.
The main steps of raising petunia in family: sowing /seedling - artificial planting - planting - maintenance - flowering period maintenance.
You can use the seedling block + the legendary three piece set to improve the success rate of seedling raising! Pay attention to the use of tap water after 1-2 days of standing to raise seedlings, do not directly use the tap water you just connected!
Soak the nursery stock in water until it is bubbled to remove excess water.
Petunia seeds are planted in the middle hole of the seedling block, and the place where the cover is placed and the balcony backlight is kept open and ventilated for 1-2 hours every day.
During this period, the seedling block appears slightly white. Add water to make the seedling block full of water, and then remove the excess water.
Wait 1 week or so for Petunia to sprout, transfer to the budding box, and let the seedlings see the scattered light. Spray water every day to keep the air and cool, as well as the appropriate humidity (do not water);
The seeds that have not sprouted are covered and aerated every day to keep moist. The seeds that have not sprouted in 10 days will not sprout again
In the process of seedling growth, more light can be seen every day, but direct light should be avoided. There are many benefits of more light in seedlings: it can prevent the leaves from turning yellow, growing in vain and not strong;
Long, long, small white root! About 20-25 days later, Petunia's seedlings look more and more robust, and its roots grow to the outside of the seedling block, so it can enter the next step - artificial planting!
Petunia's seeds are small, seedlings are small, and the pots used in the mature stage are large. Therefore, planting can greatly improve the survival rate of seedlings! The period of artificial planting is mentioned in the first step of seeding /seedling raising: the seedlings grow white flower roots.
You can use disposable paper cups or small flowerpots to implant Petunia.
If a paper cup is used: drill holes at the bottom of the cup, plant the seedling block + seedling soil together into the paper cup and pour water through it;
Keep the seedlings in a well ventilated place, see more sunlight, and spray water in the morning and evening to keep them moist (water thoroughly every time);
When the leaves of Petunia's seedlings grow to the mouth of cup or basin, and the roots almost come out from the bottom of cup, we can carry out the next operation - planting!
Use the right flowerpot and soil, make sure the sun is shining, and wait for the petunias to thrive!
The flowerpot should be 20cm or more to ensure the space of petunia in the middle and later period.
Flower soil can be purchased directly from flower market or prepared by yourself: 70% of garden soil can be mixed with a little flower soil, honeycomb cinder and perlite.
Take out the whole Petunia seedling without destroying its root (tear the paper cup directly), and implant it in the prepared flowerpot;
First place petunia in a cool and ventilated place for 1-2 days, and then move it to a sunny place such as the balcony to fully receive sufficient sunlight.
After planting, it is necessary to apply fertilizer regularly, with a period of 10-12 days. It can be used alternately with foliar fertilizer and flushing fertilizer. Scientifically fertilize Petunia to ensure sufficient water and sunshine. Just wait for Petunia to grow up quickly!
After planting, after reasonable maintenance, Petunia seedlings will grow up day by day, and finally become a beautiful flower ball!
By pruning, topping and plucking the petunia to create the perfect flower ball;
Nitrogen fertilizer should be used in the early stage of fertilization, and more phosphorus fertilizer should be used in the later stage to make the flowers and seedlings more robust and open better.
Attention should be paid to Petunia curing in summer: when the temperature is too high, spray water more to keep the soil moisture;
In winter, the petunia shall be guaranteed to receive sufficient sunlight (the temperature is higher than 5 ℃), and it shall be able to resist low temperature to a certain extent.
In winter maintenance of Petunia, we should pay attention to: less water, it is recommended to water when the sun is abundant at noon, not too much water, let the seedlings and flowers drink enough!
Petunias usually bloom in the early spring of March, when it is just turning warm. If the early flower type is not good enough, it can be cut off.
When the flower heads appear a lot at a time, you can keep them and wait for them to bloom.
Scientific fertilization should also be carried out during flowering. It is suggested that fertilization should be carried out in 10-12 days.
Petunia must ensure sufficient sunshine: sufficient sunshine can greatly improve the quantity and quality of flowering. If there is no sunshine, it is easy to suffer from malnutrition - the leaves turn yellow, soft, and the colors are dim and small.
Petunia likes sunshine, like the soil with fertilizer, and is afraid of drought; under the premise of not overstocking water, keep enough water, see more sunlight, there will be flowers when there is sunshine.
Petunia is as strong as a cow, and generally will not have diseases, but too much watering will cause rotten roots to die. Excessive drought can also cause yellow leaves, wilting and even death.
In a word, do a good job of the above-mentioned family Petunia skills, you must have a beautiful group of petunias, come on ~!
