Sunflowers wither in winter, will they grow again the next year?

Yes. The leaves of the sunflower are dry and soft, you can cut off the dry and soft leaves, and adjust the maintenance method according to the cause of dryness and softness. The leaves are dry and soft, if it is the cause of lack or exposure, you can adjust the sunlight and keep it in a bright and suitable place.

If it is the reason for the water to soak the roots, you can pay attention to water control, properly loosen the soil, maintain good ventilation, and cut off the rotten roots. If it is the cause of low-temperature frostbite, it can be moved to a warm place for maintenance and raise the temperature.

Yes.

Sunflowers are not frost-resistant, they will die in winter, after the frost falls every year, the double-petaled sunflower will be moved indoors to shine into the sun, and placed on the inside of the glass window after winter, so that the potting soil is a little drier, and it will be safe to overwinter, and after the Qingming in the following year, the flower pot can be placed outside the window, and in case of cold snap, it is also necessary to maintain it in the window.

Sunflower cultivation method:

1. Soil: extremely barren and thin, the general soil can be adapted, and the sandy soil with good drainage is the most suitable, you can use 3 parts of pastoral cooked soil, 5 parts of yellow sand, 2 parts of chaff ash or fine sawdust, and then add a little superphosphate powder to mix evenly.

2. Light: Sunflowers like full sunshine, and if they can ensure sufficient sunlight during the whole growth period, they can be lush and flowery.

3. Temperature: Sunflower likes warm climate, germination temperature 21 24, about 7 10 days of seedlings, seedlings are extremely weak, so if the temperature is maintained, the seedlings grow quickly, and can form relatively thick, fleshy branches and leaves.

Sunflower, also known as purslane grandiflora, is an annual herbaceous plant. In winter, when the temperature is low, the stems and leaves of the sunflower growing outdoors will wither, and the bottom part of the plant will still survive, and buds will grow when the weather is warmer. Potted sunflowers should be protected in winter, placed in a warm place indoors, and watered less to make the plants safely overwinter.

Sunflower, also known as purslane, half-branched lotus, pine-leaved peony, etc., is an annual herbaceous plant. It blooms in June and September and bears fruit in August and November, and when the fruit is ripe, it will produce seeds, and if the seeds are not collected, they will be sprinkled into the soil, and small seedlings will grow in the spring.

Sunflowers like warmth and are more hardy to cold, and when the temperature is low in winter, the surface part of the earth will gradually wither and die. The underground part is still alive and will begin to sprout when the weather warms up. Sunflower seeds are small and may be blown away by the wind when they fall into the soil after maturity, and they are more adaptable to the soil and will sprout when the temperature is right.

When the temperature is 21 24, the plant can emerge in 7 to 10 days, and the sunflowers in the seedling stage are extremely weak, so it is necessary to maintain high temperature to promote plant growth. In winter, the sunflower will wither, so after the summer harvest, the rhizome can be dug out of the ground, and the roots that are in good condition can be divided, and then planted, and with proper maintenance, more sunflowers can be harvested the next year.

In the southern region, the temperature is high in winter and generally does not wither, so the sunflower should be moved indoors to a sunny place for maintenance. During the winter maintenance period, it is necessary to reduce watering to make the soil dry and avoid frostbite of the rhizomes of the plants. Sunflowers are afraid of waterlogging, so in the wet and rainy season, it is necessary to reduce watering, and loosen the soil to increase drainage and air permeability.

Sunflowers do not need to be replanted the following year.

Sunflower has poor cold tolerance, and if the temperature is well controlled in winter, it does not need to be replanted the next year, and its rhizome will continue to germinate.

However, if it is in a low temperature environment, it will freeze to death, and it will need to be replanted the next year. Sowing multiplication and growth rate is also very fast, it is still recommended to re-sow so that the flowering can be better.

Sunflower planting method:

1. Prepare potting soil:

Before planting sunflowers, prepare well-breathable and fertile soil, so that sunflowers can breathe better and absorb nutrients before germination. It is recommended to add chaff ash and yellow sand to the garden soil when mixing the soil. Note that it must be disinfected before it can be used.

2. Sowing seeds:

Sunflower seeds do not need to be treated before they are placed in the soil, as long as the seeds are full. The sowing method is also very simple, sprinkle the seeds directly on top of the prepared soil, then cover with a thin layer of soil, and water thoroughly in time. If you want it to bud better, you need to control the temperature well, the temperature is about 20 degrees, and it will bud in about 10 days in such an environment.

3. Timely transplanting:

After germination, the sunflower seedlings should slowly increase the light, bask in the sun more, and water frequently, so that the growth rate is relatively fast, and the seedlings will grow very robust after sowing for about a month, and they can be transplanted. When transplanting, try to protect the root system, water thoroughly after planting, and maintain it in a warm and ventilated place, which will soon resume growth and flowering as scheduled.

No, the general root-based sunflower is easier to maintain for a longer time than the sunflower sown from seeds. That is to say, the sunflower planted with seeds is generally raised for a year, and the sunflower planted with branches and roots is longer.

In autumn and winter, in order to allow the sunflower to continue to grow in the second year, it must be placed in a warm place, can be placed indoors to the sun, the temperature can not be lower than 4 degrees, and at the same time, in order for it to survive the winter normally, accumulate nutrients, will not consume too much nutrients, cut off a large part of the branches in time, so that it can survive the winter smoothly.

In the spring, it will gradually take care of it normally, and do not take the sunflower pot outside too early to maintain it, so that as the temperature rises, it can sprout on its own and continue to bloom.

After the sunflower withers in winter, it can also regenerate in the second year, because it is the branches and leaves above the ground that the sunflower is wilted, but the rhizomes in the sunflower soil are still active, and when maintaining the sunflower, it can provide it with all-day sunshine, keep the leaves green, and can also provide pollution-free river water for the sunflower to keep the soil moist.

1. It can be regenerated

After the sunflower withers in winter, it can regenerate. Because the rhizome of the sunflower is more developed, when the ambient temperature decreases, the branches and leaves above the ground will dry up and die, while the rhizomes below the ground will remain active, and when the temperature rises, new branches and leaves will grow at the rhizome, so the sunflower will regenerate.

2. Provide light

In the process of growth, the sunflower is inseparable from the light, in the process of maintenance, it needs to be placed in a sunny environment, so that the plant can receive all-day sunshine, bloom bright flowers, and the sunflower is not afraid of the sun, and can grow normally in the environment with too much light, and does not need to take shading measures.

3. Scientific fertilization

Sunflower is suitable for growing in a more fertile environment, in the daily maintenance, it can be watered with rotten farm fertilizer, or green manure, cake fertilizer, to maintain the growth of the plant, in the period of vigorous growth of the sunflower, you can provide it with a balanced nitrogen, phosphorus and potassium compound fertilizer, so that the plant grows better.

4. Replenish water

In the process of maintaining the sunflower, it can be watered every three days to keep the soil in a moist state, but in the summer when the temperature is high, you can water the sunflower twice a day, and in the winter when the temperature is lower, you can stop watering, or water it every half month to avoid frostbite at the roots of the plant.

When the sunflower withers in winter, it should be moved to a astigmatism environment with a temperature of more than 10 degrees, and the plants should be watered every 15 days to keep the soil slightly dry, and at the same time stop fertilizing the sunflower to prevent fertilizer accumulation inside the potting soil and accelerate the speed of plant wilting.

1. Swap the environment

When the sunflower withers in winter, it should be moved to a sunny place indoors as soon as possible, and the room temperature should be maintained in the range of 10 to 15 degrees, so that the sun lake can enter a semi-dormant state, so that the branches and leaves can gradually resume growth, and at the same time reduce the consumption of water and nutrients by the plants.

2. Control watering

The root system of the sunflower has strong water storage, so in order to avoid frost damage to the plant in winter, the potting soil should be in a slightly dry state, avoid frequent watering, destroy the protection of the soil to the root system, and pay attention to when the soil is completely dry, water warm water for the sunflower to prevent the root from being damaged by frost water.

3. Stop fertilizing

Sunflower will enter a dormant state in winter, during the maintenance process, to stop the operation of fertilizing the plant, in order to prevent the root system from burning the root, pay attention to before winter, it is best to apply a base fertilizer to the sunflower to ensure that the nutrients in the potting soil can support the growth of the plant in winter.
