How to make petunias bloom in winter, how to survive the winter

Petunia is a more common flowering plant, generally petunia from sowing to flowering takes about 2 3 months, some flower friends hope that their petunia can bloom in winter, this is not impossible, but still need to raise the environment to meet certain requirements.

Petunia (details).

If petunia blooms in winter, then we need to sow seeds in autumn, and what we want to say here is that flower friends need to ensure that there is heating at home, that is, the temperature is right, if there is no heating, and it is north, then petunia cannot bloom in winter, and it is possible to freeze to death.

On the other hand, if there is heating in the flower friend's home, and the light conditions are good, and the petunia is sown in autumn, then it is very easy for the petunia to bloom in winter!

Since it comes to winter, here are some data for petunia winter, the growth temperature of petunia is 13 18, and the winter temperature is 4 10, if it is lower than 4, the plant growth stops, and it can withstand 2 low temperatures.

Petunia (details) should be placed on the windowsill or close to the windowsill in the sunny indoor to pay attention to ventilation, not only when you just enter the room to ventilate, throughout the winter, but also should open the window at noon in sunny weather for ventilation, which can not only reduce the occurrence of pests and diseases, but also conducive to the healthy growth of flowers. Sufficient light is the key to the growth of petunias, and if enough light can be ensured, it is also the key for petunia to survive the winter.

The cold hardiness of petunias is still good, as long as it is less than freezing. Older seedlings are more resistant to cold.

It is not difficult for petunia to bloom, small seedlings generally need a vernalization process before flowering, yours is a flowering plant, so as long as the temperature can be guaranteed above 12, as long as the leaves can be flowered!!

Put it in a sunny place, watering should be dry and wet alternately, if the room temperature is higher than 16, you can apply a small amount of fertilizer, fertilizer in nitrogen, phosphorus and potassium to be comprehensive.

When petunias are maintained in winter, they should be placed outside to receive sunlight during the day, and moved indoors at night and paid attention to ventilation; In winter, reduce the frequency of watering, knock the soil before each watering, and water it after drying; Fertilization is not required in winter, and diluted nitrogen fertilizer can be used appropriately after the leaves wilt; After being infested by aphids, it is necessary to use pyrethrin for control.

Petunia needs the right light when growing, so how to survive the winter, the light is not strong in winter, and the slag can be trapped outside to receive sunlight during the day, but it should be noted that the temperature is cold in winter, and it should be moved indoors for maintenance at night; Attention should be paid to ventilation indoors to strengthen the circulation between air. Beam thick.

In winter, the root system of petunia is in the closed period, so it is necessary to reduce the number of watering times to prevent root rot in the root waterlogging; Observe the soil moisture before watering, and tap the soil surface with your hands to make a crisp sound to represent the soil dryness, indicating that watering can be carried out.

If the plant leaves are found to have a dull withering phenomenon in the maintenance process, it is necessary to immediately use the diluted liquid nitrogen fertilizer and bury it in the soil, so as not to contaminate the leaves, so as not to cause burns to the plant.

In winter, the plant has poor self-defense ability and is susceptible to aphid infestation, which parasitizes on the stems and leaves of petunia to absorb nutrients, and in severe cases, it will cause plant death; When this pest is found, spray it with pyrethroid and stick to it for a week to restore health.

The temperature is suitable, the appropriate temperature is 13 18, and the temperature is controlled above 4 during indoor breeding; Reduce watering, watering once in 10-15 days in winter; Reasonable fertilization, before winter, apply a rotted organic fertilizer, stop fertilization in winter, and after warming, top dressing once nitrogen; Zhenchengkuan pest control, the use of pyrethrin, multiling, etc. to prevent aphids, scale insects.

The climate is cold in winter, and petunias have weak cold tolerance, and the suitable growth temperature is 13 18. In the north, it is recommended to maintain indoors, the temperature is controlled above 4, and the ground planting can be built to build an insulation shed to prevent frostbite leaves. The temperature in the south is mostly around 10 in winter, which can be placed in a ventilated and sunny position, which is conducive to normal growth.

Petunia enters the dormant period after winter, metabolism is slow, reduce the number of watering, an average of 10 15 days watering once, the time should be selected at noon with a higher temperature, the water temperature should be close to the ambient temperature, the potting soil is kept slightly dry, to avoid water accumulation leading to rotten roots, resulting in leaf fall or long phenomenon, affecting cold resistance and brightness and flowering in the next year.

Petunias need to stop fertilizing during the winter months. Before winter, apply a well-rotted organic fertilizer, or phosphorus and potassium compound fertilizer, to store nutrients for overwintering and improve cold resistance. Add water to dilute when fertilizing to reduce the concentration of fertilizer and prevent the accumulation of bent material before fertilizer and burn the roots.

After the spring warms up, top dressing a thin nitrogen fertilizer.

Petunias are less resistant in winter and need to be protected against pests and diseases. Winter will cause aphids, scale insects, etc., when exterminating insects, use a rag dipped in the venom, slowly wipe the infected leaves, can not spray pesticides directly, after disinfection, put the potted plants in a cool and ventilated place. The disinfectant solution is recommended to use methrin, multiling, etc.

If the temperature is too low, you can temporarily carry it indoors for maintenance, so that controlling the temperature can help the plant grow better.

Friends who have raised petunias are basically aware that this plant is very light-loving, no matter what season it is, it likes to grow in full sun. At least four or five hours of direct sunlight should be ensured every day, otherwise not only will the number of flowers bloom small, but also the color will not be so bright, which greatly affects the flowering probability of petunias.

In the winter maintenance of morning glory is still particular, such as the need to reduce the water appropriately, after all, at this stage if the soil humidity is too high, there will be water residue in the pot, so that the roots of the plant will not only be frostbitten inside, but also allow the oak to be easy to be suffocated, resulting in poor growth in the end.

Notes:

When maintaining this plant in winter, it is also necessary to prevent the interference of germs and insect pests. In particular, the Liangjian plant should not be kept in a humid environment, otherwise it is more likely to breed germs and insect pests, and the petunia can be transported to a ventilated location to allow air to circulate, so that the flowers can grow healthily.

In winter, when the environment is dry, after moving the petunia indoors, keep the environment ventilated throughout the winter, and when the weather is fine, you can open the windows at noon for ventilation.

Petunias need topping after flowering, and proper topping can increase the growth rate of the plant and make it grow more vigorously. At the same time, it is necessary to disinfect and sterilize the topping wound of the plant after topping, so as to avoid bacterial infection of the plant, and after topping, it is also necessary to provide appropriate water and nutrients for the plant to help the plant recover its vitality as soon as possible.

1. It needs to be topped

Petunias need topping after flowering. Petunia blooms around April each year, which is the time period when the plant grows more rapidly, and topping the plant at this time can increase the growth rate of the plant, so that the plant grows more side branches for flowering. At the same time, you need to choose the right tool before topping, and it is best to use scissors with sharp edges for topping.

2. Topping method

When topping petunias, you need to use the correct topping method, first you need to choose scissors with sharp edges, and then use scissors to cut off the young buds and young leaves that grow on the top of the plant, inhibit the growth of the top of the plant, and promote the plant to grow more side branches, and also need to cut off the withered buds of the plant to save nutrients for the plant.

3. Post-maintenance

When caring for petunias after topping, it is necessary to provide the plants with appropriate water to help the petunias recover as soon as possible and continue to grow. At the same time, it is also necessary to provide appropriate nitrogen, phosphorus and potassium compound fertilizer for the plant to improve the growth rate of the plant and let the plant grow side branches as soon as possible. And when fertilizing, you need to pay attention to the amount of fertilizer, and it is best to dissolve the fertilizer in clean water and provide it to the plants.

4. Precautions

After topping petunias, it is necessary to disinfect and sterilize the topping wound of the plant to avoid disease on the plant. At the same time, after topping, the plant needs to be maintained in a cool and ventilated environment, so as to avoid the wound of the plant in a sunny environment that is difficult to heal, and it is best to provide light for the plant after the plant recovers growth.

Petunias bloom from April to October, and bloom continuously in warm winter areas. It is possible to prolong or shorten the flowering period in different environments, and a well-raised petunia will basically not break the flower, and the single flower of the petunia can generally bloom for 4 to 5 days.

Petunias, Solanaceae, Agaricus Winteraceae. Also known as Bidong eggplant. perennial herb, often cultivated for one or two years, 20-45 cm high; The stems are creeping and pubescent; leaves soft, ovate, entire, alternate, upper leaves opposite; The flowers are solitary, funnel-shaped, double-petaled spherical, white, purple or various red, and inlaid with other color edges, very beautiful, flowering from April to frost; Capsule; The seeds are small.

It is found in South America and is now widely popular in various countries.

Petunia is a long-day plant that requires full sunlight during the growing season, and it takes about 100 days from sowing to flowering under normal light conditions. When petunias are cultivated in winter greenhouses, the stems and leaves grow luxuriantly under low temperature and short day conditions, but it is difficult to flower, and when the spring enters the long sunshine, the flower buds quickly differentiate from the top of the stems and leaves.

Petunias are large and numerous, blooming vigorously, with a long flowering period and rich colors, which are excellent flower beds and planting bowl flowers, and can also be planted in natural clusters and can also be used as cut flowers. It can bloom in all seasons if the climate is suitable or it is cultivated in a greenhouse. It can be widely used in flower bed arrangement, planter configuration, scenic spot decoration, window sill decoration, and home decoration.

Petunia flowering is continuous blooming, which can bloom continuously for two to three months under normal circumstances.

Petunias have a long flowering period and bloom from May to October.
