How to maintain leafy sunflowers? How to plant and maintain sunflowers

It's the season of raising sunflowers, friends who have raised flowers must have an understanding of sunflowers, flowers that are not afraid of high temperature and drought, among the flowering plants in summer, the drought resistance of sunflowers is the strongest, there is no flower that can match the sunflowers, drought-resistant plants have a little benefit, good to feed, can not die.

Sunflowers are grown on the side of the road, there are a lot of roads on both sides of the hometown, they are wild, the varieties are almost the same, the flower color is reddish, yellowish, only these two, when they are born, they bloom and die, after the petals wither, they will grow seeds, and the seeds will continue to grow and bloom in the spring of the next year, when the temperature rises, the seeds will continue to grow and flower.

Sunflower is the most vigorous of the flowers I have raised, the high temperature of 30 degrees in summer, can not be baked in the cement ground, and can still bloom the next morning, like this kind of plant that can not die, the most suitable for raising at home.

Home-planted sunflower and wild sunflower varieties are completely different, potted sunflower is specially cultivated for horticulture, flower color, variety, ** will be more expensive, in fact, it is too much of this plant, as long as you can get the branches into your hands, basically you don't need to buy it anymore, you can multiply infinitely by branches alone, and there are seeds after the flowers.

Seeds can be wrapped in newspaper and planted in the coming year, but the acquisition of different varieties will be a little troublesome, and some have to spend money to buy, in the past, my family also raised five or six varieties of sunflowers, and then because I liked enough, I gave them to friends, and the succulents raised at home had no place to raise sunflowers.

It is not recommended to use nutrient soil to plant sunflowers, ordinary loess and half of the nutrient soil are mixed together, and the effect of planting sunflowers will be better.

Share a little trick for raising sunflowers, you can definitely use it, there are countless "growth points" on the branches of sunflowers, and there are many growth points, indicating that the survival rate of cuttings is high, when the branches of sunflowers raised at home grow to a length of 15 cm, or even longer, pinch down from the middle part, in fact, it is enough to keep the branches of sunflowers at 10 cm.

Usually ensure that it has sufficient sun exposure and appropriate amount of water, occasionally prune its leaves, which is conducive to its full absorption of nutrients, and occasional fertilization can also be conducive to its healthy growth.

The leafy sunflower can not be exposed to the sun, and the usual watering can not be too much at one time, and the leafy sunflower should be fertilized once every half a month.

Personally, I think it is kept indoors. Water once every 7 days or so, and water thoroughly every time.

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.

1. Good light: Sunflowers like light, so you can move the potted plants to a sunny place outdoors for maintenance. 2. Reasonable watering:

Water frequently during the peak growing season, and strictly control the amount of water in winter. 3. Apply fertilizer frequently: apply phosphate fertilizer and potassium fertilizer every half month before flowering.

4. Flower pot selection: the diameter is about 15-20 cm, which is conducive to the bursting of the sun.

1. Good lighting

Sunflowers like light, can not leave the sun during the growth period, daily maintenance of sunflower potted plants, need to be placed in a well-lit place, to provide all-weather sunshine for the plant, do not put the potted sunflower in a cool place, otherwise the branches and leaves will grow, affecting flowering.

2. Reasonable watering:

Sunflower is drought tolerant, but the growing season consumes more water, to replenish water in time, and each watering to water thoroughly, until the bottom of the pot has water out, in addition to winter to control the water, so that the soil remains dry, to prevent sunflower from frost damage.

3. Apply fertilizer frequently

If you want to make the potted sunflower bloom vigorously, you need to apply fertilizer frequently, you can apply a sufficient amount of phosphate fertilizer and potassium fertilizer every half a month, which is conducive to the color of the flowers more vivid, pay attention to the fertilizer concentration should not be too high, otherwise the sunflower will burn the roots.

4. Flower pot selection

Do not use a large pot when potting sunflowers, otherwise the soil will be in a moist state for a long time, which is not conducive to the growth of plants, you can choose a pot with a diameter of 15-20 cm, which is suitable for root stretching, and the sunflower will achieve the effect of bursting pots in the later stage.

Sun flower potted plants should be placed in a well-lit place, preferably exposed to the sun all day, and sufficient sunlight can promote vigorous growth and better flowering. Sunflower has a certain drought tolerance, watering does not need to be too diligent, find that the soil is dry and water thoroughly in time, do not dry do not water. The sunflower consumes a lot of nutrients in the peak growth season and flowering period, and the potted plant maintenance should also be topdressed, and the nutrition is sufficient to grow vigorously, and better flowering, you can use Bika potassium dihydrogen phosphate.

In addition, the soil should be changed every year to ensure that the soil is loose and breathable.

1. Sufficient light: Place it in a well-lit place to provide all-weather sunshine for the sunflowers. 2. Scientific watering:

Water more during the growing season, but control water in winter to keep the potting soil dry. 3. Apply fertilizer: apply a sufficient amount of phosphorus and potassium fertilizer before flowering.

4. Precautions: Replace the new soil once a year and use breathable and fertile soil.

1. Sufficient light

Sunflowers like light, can not leave the sun during the growth period, usually put the potted plants in a well-lit place, to provide them with all-weather sunshine, is conducive to better flowering of plants, if the sunflower is placed in a cool place, the branches and leaves will grow, affecting the appearance.

2. Scientific watering:

Potted sunflower grows in the peak season consumes more water, to replenish water in time, each watering to water thoroughly, but can not appear waterlogged, to avoid roots, in addition to strict control of water in winter, so that the potting soil remains dry, is conducive to the safe wintering of sunflowers.

3. Apply fertilizer

Sunflower has strong adaptability to the environment and is barren tolerant, but in order to make the plant bloom vigorously, fertilizer should be applied frequently, and phosphorus fertilizer and potassium fertilizer should be applied once half a month before flowering, which is conducive to flower bud differentiation and promotes the color of sunflower to be more vivid.

4. Precautions

Potted sunflowers must ensure that the soil is loose, replace the soil once a year, and use soil with strong air permeability, good drainage conditions and rich organic matter, so as to avoid the potting soil compaction and hinder the healthy growth of sunflowers.

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.

1. Illumination. Sunflower is very dependent on sunlight, it can be said that the growth of sunflower is inseparable from sunlight, so it is especially suitable for cultivation in the courtyard or rooftop, even if it is cultivated indoors, it must give enough sunflower enough light, more than 8 hours a day is the best, otherwise it will lead to the consumption of nutrients in vain, which is very unfavorable to flowering. In the summer, when the weather is hot, it is necessary to maintain ventilation and do not need additional shade work.

2. Temperature. Sunflowers are not hardy and grow most vigorously at 25 to 30 conditions, it doesn't matter if it's hot, but when the temperature is low, the growth of sunflowers will be slower and slower until it stops growing. Therefore, in order for the sunflower to survive the winter, it is necessary to keep the weather above 10 in winter, also to prevent frostbite.

3. Watering. Sunflower is drought tolerant, not afraid of dry soil and air, but can not accept too humid environment, so the amount of watering must be grasped, only in dog days when the water evaporates too quickly need to increase the amount of watering, you can use the principle of "see dry and wet" watering, each time watering thoroughly, not dry and not watering.

At the same time, in order to prevent the rapid loss of water in the hot summer, we must avoid watering at noon when the temperature is the highest, and you can choose to prevent the sunflower from suddenly encountering the cold water temperature in the early morning or evening, when the difference between the air temperature and the water temperature is not large, to prevent the sunflower from suddenly encountering the cold water temperature at the high temperature and causing rapid wilting.

Fourth, fertilization. Because the sunflower is very adaptable, it does not need special soil requirements, but if you want the sunflower to bloom longer, you need to rely on fertilization to assist. Compound fertilizer can be applied once during the growth period of sunflowers, and potassium or phosphate fertilizers can be applied every half a month before flowering, so that the sunflowers get enough nutrients and produce more and more vigorous flowers.

There are no specific requirements for the quality of compound fertilizers.

Also known as "can't die", sunflowers are particularly drought-tolerant plants, and even if they forget to water them, they will wilt due to drought in a short period of time. Therefore, it is very worry-free to raise sunflowers.

Sunflower is drought tolerant, but it does not mean that it does not need to be watered reasonably, during the seedling period, due to the scarcity of stems and leaves, it is necessary to keep the potting soil slightly moist to provide it with sufficient water, so that it can better grow side branches. When the plant is about to sprout, you should not water it too much, because at this time the plant begins to grow flower buds, and if there is too much water, the plant may continue to grow new branches and leaves, and neglect to grow flower buds and flowering. Keeping the potting soil a little drier will encourage the plant to grow flower buds.

The sunflower at the seedling stage does not need to be fertilized too much, as long as it is occasionally watered with some thin fertilizer water, the plant can thrive. When the new branches and leaves are very lush, you should give it more fertilizer to promote flowering. If you want the sunflower to grow vigorously and bloom more, you need to supplement more phosphorus and potassium fertilizers, but other elements should also be supplemented, because it blooms while growing new branches.

Finally, remember to trim in time. Sunflower blooms more frequently, it is flowering stubble after stubble, if you do not prune after each flowering, the branches that have bloomed can no longer bloom, and it will also occupy a lot of nutrients, affecting the plant to give birth to flower buds again. When the plant finishes flowering, it is necessary to prune off the residual flowers in time, cut off the thin and withered yellow branches, and cut the branches that are too tall and too long to reduce the waste of nutrients.
