How to maintain sunflowers in autumn and how to raise sunflowers in winter

1. Potting soil selection.

Sunflower grows vigorously, needs to have loose and breathable, nutrient soil, you can directly use nutrient soil to plant, the pot is larger or smaller, but it must be breathable and permeable, otherwise the root system is very easy to rot roots. After a long time, the potting soil needs to be repotted and replaced, so that the sunflower can grow longer and more beautiful.

2. The temperature is appropriate.

Sunflowers like a warm environment and are especially afraid of cold, so as long as the temperature is lower than 15 degrees Celsius, you need to take measures to keep warm, if the temperature is too low, the leaves are easy to be frostbitten, affecting the plant to survive the winter.

3. Sufficient light.

Sunflower is a very light-loving plant, usually you must bask in the sun more, have enough light for photosynthesis, synthesize more nutrients, and the growth will be better. However, if it is in a long-term environment with insufficient light, the sunflower is easy to grow, the branches are thin, the resistance is poor, and it is easy to hang up in winter.

4. Sufficient nutrients.

If the plant is still flowering, then you need to use compound fertilizer containing more phosphorus and potassium fertilizer, which can promote the differentiation of flower buds and bloom more.

5. Reasonable watering.

Sunflower for the demand for water is not high, do not need frequent watering, if too much watering, the plant is easy to accumulate water and rot roots, generally the surface of the potting soil is dry and then watering it. After watering, the sunflower will become vibrant.

6. Prune regularly.

Sunflowers grow quickly, in order to make the plant fuller, it is best to prune the branches frequently, so that the ventilation and light transmission between the branches will be better, and the shape will be better. This will help the plant grow more shoots, look fuller, and bloom more in the coming year.

Sunflower flowers are colorful, colorful and have a long flowering period, and have always been loved by people. The main reason why everyone likes sunflower is that it is particularly easy to raise, whether you have experience in raising flowers or not, you can raise it to flourish.

Sunflowers like a warm and dry climate, after entering September, with the cooler weather, sunflowers are gradually past the full flowering period, and there will be fewer and fewer blooms in the later period. However, if the maintenance and management are strengthened during this time, it can still be made to bloom in large quantities again, and many sunflowers can bloom until late autumn. Let's introduce to the pot friends how to maintain it so that the sunflower can bloom more in autumn.

First, there must be sufficient nutrients.

The growth and development of any flower is inseparable from a large number of nutrients, the sunflower blooms in large quantities, the flowering period is long, and the demand for nutrients is also very large, in order to promote a large number of plants to bloom, it is necessary to supplement nutrients from time to time. If you want the plant to bloom in large quantities in autumn, you should apply more phosphorus and potassium fertilizer to it at this time, and phosphorus can play a role in promoting flowering. It can be watered with potassium dihydrogen phosphate solution every 10 days, or it can be diluted by fermenting some cake fertilizer water and pouring it into the pot.

The best use of liquid fertilizer for sunflower fertilization, because the potted sunflower is generally close to the plant space, not suitable for the operation of the buried fertilizer method, and then the liquid fertilizer is easier to penetrate the soil, the root system absorbs and utilizes faster, and can better play the fertilizer effect.

Second, make sure that there is enough light.

Sunflowers are typical light-loving flowers, which will have few flowers and dull flowers in a hidden environment. After the beginning of autumn, the sunlight gradually weakens, and there is no longer any need to shade it, so you can place the potted plant in a sunny place and let it receive all-day sunlight. This will encourage the plant to produce more buds, more flowers, and more vibrant flowers.

Third, keep the potting soil slightly moist.

It is also known that the sunflower is a very drought-tolerant plant that grows normally even in particularly dry conditions. However, drought tolerance does not mean that it likes water, and the growth and development of any plant is inseparable from sufficient water. Therefore, it is necessary to keep enough water during the flowering period of its pregnant buds, but it is not possible to water it frequently, generally as long as the potting soil is kept in a slightly moist state, so as to meet the needs of plant growth.

Fourth, prune residual flowers and overly dense branches.

After each sunflower flowering, the broken flowers can be cut off in time, which can save part of the nutrients and provide the plant with buds again. At the same time, it is also possible to cut and thin the branches that grow too densely, and the branches that grow too long to cut it short, which can not only save a lot of nutrients, but also make the plant shape dense and compact, so that the flowers open evenly and increase the ornamental effect.

In autumn, as long as the sunflower is maintained with water and fertilizer and let it receive all-day light, it will bloom for more than a month, and even until late autumn.

When cultivating sunflowers in winter, the ambient temperature needs to be controlled between 15-25 degrees, and the frequency of watering needs to be controlled, which can be watered once every half a month, and the sunflowers need to be placed in a place where they can get sunlight, so that they can receive enough sunlight, and they need to stop fertilization, so that the sunflowers can survive the winter smoothly.

1. Suitable temperature

Sunflower is suitable for growing in a warm environment, when breeding sunflower in winter, if the ambient temperature is lower than 5 degrees, it will cause the plant to be frostbitten, so that the sunflower dies, the sunflower needs to be moved to a warm room for maintenance, and the ambient temperature needs to be controlled between 15 degrees and 25 degrees, so that the sunflower grows healthily.

2. Control watering

When breeding sunflowers in winter, if watering too frequently, it will lead to water rotting plants, so that sunflowers wilt and die, you need to control the frequency of watering, you can water once every half a month, watering needs to keep the temperature of the water and the indoor temperature consistent, so as not to make cold water frostbite sunflowers.

3. Lighting conditions

Sunflowers need sufficient light during the growth process, and when cultivating sunflowers in winter, they need to be placed indoors in a place where sunlight can be irradiated, so that sunflowers can receive all-weather natural light, so that they can fully photosynthesize, and plant fill lights can also be used to supplement the sunflowers.

4. Stop fertilizing

When maintaining the sunflower in winter, you need to stop fertilizing, because the sunflower will be in a semi-dormant state in winter, at this time, if too much fertilizer is applied, it will lead to fertilizer damage to the plant, which will make the sunflower rot roots, you need to wait until the weather warms up and the temperature rises, and then apply fertilizer to the sunflower to make it grow vigorously.

The sunflower is also called the can't die, the double-petaled one is called the pine-leaf peony, and it is called the half-branch lotus, etc., which is sun-resistant and heat-resistant, and has a lot of flowers, which can not only be cuttings, but also very easy to sow and reproduce. A friend raised many pots of sunflowers on the terrace before, at first there was only one pot, or a small seedling, raised on the terrace for a month, and now has begun to grow a lot of buds, almost every day is blooming, has begun to bear seeds, many flower friends also through the method of sowing seeds with seeds, sowing some sunflower seedlings, out of a lot of seedlings, the state of the buds will grow as good as possible.

The process, experience, and skills of sowing potted sunflowers on the balcony

First, the sowing time of the sunflower

Generally the most suitable for April and May, the temperature in most areas of the general month is still relatively low, may affect germination, the temperature reaches more than 20 degrees is more appropriate, if the temperature is too low can be placed next to the heating, or covered with a film, as long as the temperature is suitable, the pot soil is loose and breathable, generally five or six days to germinate.

First of all, we need to prepare some loose and breathable soil, but it is best not to use too fertile soil, too fertile soil is really not suitable for sowing, or do not put organic fertilizer at the beginning, after fertilizer, it is easy to burn seedlings, and it will not grow well.

Then sow the seeds, because the sunflower seeds are small, you can not cover the potting soil, watering can be done with a watering can, spray gently. Keep it moist to a certain extent, and it will germinate in ten days, and its sprouts are very small and very small.

Second, bask in the sun after germination

In fact, as long as the sunflower seeds are not expired, the germination rate after sowing is very high, and the sun must be more after germination, otherwise it will be because of the lack of light in the back, it will grow in vain, and it will be more troublesome, stretching the neck like a thin bean sprout, only long stems and no leaves, which are fragile and difficult to maintain.

If the sunflower seedlings have white hairs, or rotten stems and rotten seedlings, it is likely that there is too much watering, the soil is not breathable, or when it rains, the rain is too long, resulting in the rotten roots or rotten stems of the seedlings, so at this time, we must grasp the watering well, the potting soil is slightly dry and then watered thoroughly, do not water at every turn.

Usually give them the sun, but not in the sun, the morning sun can also fertilize and water them, so that they can grow better.

Sunflowers are a very good plant, as long as they are properly watered when they are short of water.

In normal times, we should ensure its light time and ventilation time, and also pay attention to whether its moisture and nutrients are sufficient. When it encounters insect infestation, we also need to be timely**.

Clause.

1. Temperature

Temperature is the key to the growth of sunflowers, germination to flowering, normal planting, sunflowers can be planted in spring, summer and autumn three seasons, but in order to make sunflowers grow better, then we need to control the temperature of sunflower growth to ensure that it can grow quickly, the most suitable growth environment temperature of sunflower is 20 degrees Celsius up, only above this temperature can ensure that sunflower can have a good chance of growth, Therefore, when we are planting, we must control the temperature to ensure the growth of sunflowers.

Clause.

2. Illumination

The light resources required by the sunflower are very large, when there is no light, the petals of the sunflower will be closed directly, so the sunflower is also named, when we plant the sunflower, the sunflower should be planted in the summer or so, so as to basically ensure that the sunflower has enough light to grow.

Clause.

3. Correct fertilization

It does not have high requirements for fertilizer, just apply potassium dihydrogen phosphate once every half a month, so that it can make its flowers big and bright, and the flowering period will be longer.

Clause.

Fourth, light

It likes sunny places, so be sure to get plenty of sun as it grows, so that it can flourish.

Fifth, take the head

When the seedlings grow to a centimeter height, branches grow from the roots. At this time, the tip of the main branch is removed, and soon a cluster of shoots will sprout at the fracture. When the branches of the roots grow to a certain length, the branches can also be plucked, and after this treatment, the sunflower is dwarfed and the plant shape becomes more beautiful.

Sunflower is the flower language of various flowers, because it is shaped like the sun. So it gives people a sense of vitality and joy. So how should sunflowers be maintained?

Generally speaking, sunflowers prefer a sunny and dry environment, and should be dark and damp when growing, and can adapt to any soil and grow freely. Therefore we should:

First: choose the planting environment. Sunflowers prefer dry sandy soils, so we choose fertile and well-drained yellow sandy soils for planting. And try to water as little as possible, otherwise it will cause sunflower root rot.

Second: fertilization.

Although it is said that the sunflower will grow freely under any circumstances, in order to get a more colorful and vibrant sunflower, we should also fertilize it appropriately. (It must not be too bad, otherwise it will cause rotten roots.) Fertilizer is applied once every half a month or so.

And potassium dihydrogen phosphate is the best. After fertilization, it should be watered in time and placed in a ventilated environment under the sun.

Third: nursing. Sunflowers should be often interrupted (topped and topped) so that they can grow more and more vigorously and produce extremely bright flowers.

So why does the sun rent pure flowers still have the phenomenon of rotten roots? From the above points, we can see that the main reasons for Reagan are:

1: Rotten roots caused by too much watering.

2: Root rot caused by untimely drainage.

3: Root rot caused by too much fertilizer.

No matter what the cause of the rotten roots, as long as it appears, we should be in time**. Cut off the rotten roots, replant them in soft, sandy soil and place them in a sunny environment with good air circulation, and fertilize them properly. In this way, the sunflower will grow vigorously again.

Through our introduction, I believe that you have a deeper understanding of the correct method of sunflower maintenance.

The methods of planting and maintaining sunflowers are as follows: planting time, soil preparation, sowing planting, cultivation and germination, and post-planting management.

1. Planting time

There are no strict requirements for the planting time of sunflowers, and it is best to plant them in spring. Because the spring climate is mild, it is suitable for plant growth and has a high survival rate.

2. Prepare the soil

Sunflower growth bark should be done in loose, fertile, permeable and well-drained soil. Humus soil, garden burn talk about the base forest soil and sand river soil can be. A small amount of organic fertilizer can be added to increase the organic nutrients of the soil.

3. Sowing and planting

Choose plump seeds that grow well and spread them evenly in the soil. Keep the temperature above 20 degrees, water lightly, and cover with a thin layer of soil. Sunflower seeds will take root and sprout in a warm, moist environment.

4. Cultivation and germination

After the seeds germinate, they need sufficient light time, at least 8 hours of light time per day. The temperature is above 20 degrees, and diluted nitrogen, phosphorus and potassium compound fertilizer is used after 7-10 days. Water once every 2-3 days.

5. Post-planting management

After the sunflower is planted, it needs to be carefully managed. The temperature is stable in spring and autumn, and the temperature is high in summer, so it should be avoided from high temperature weather and placed in a cool position for breeding. In winter, the temperature is low, not lower than 5 degrees.

It can be placed indoors in a well-lit location. Water once every 2-3 days in spring and autumn, and once every 1-2 days if the water evaporates too quickly in summer. Spray it with insecticides or carbendazim to avoid pests and diseases.
