Sunflower planting methods and precautions: watering is very important

Sunflowers are known for their unique flowers, and their most distinctive feature is that the flowers always open toward places with plenty of light, so more and more people like to grow them. So what is the most correct way to grow sunflowers? Today we will take a detailed look at the cultivation methods and precautions for sunflowers.

How to grow sunflowers

Because sunflower flowers are very popular, they have a strong market, and some people specially grow this Asteraceae herbaceous plant, but most people grow it for ornamental purposes. Therefore, today we mainly introduce how to grow potted sunflowers, focusing on temperature, water, light, soil and other aspects of sunflower cultivation methods and precautions.

1. Potting

Usually, when the sown sunflower has grown 4-5 tender leaves or the seedling has already taken root, it needs to be transplanted into a flowerpot. Here the propagation method of sunflowers is involved, so for beginners it is not recommended to start from this step. You can directly buy already-potted sunflowers from the market for growing.

2. Light

Although sunflowers sound very dependent on light, in the cultivation methods and precautions for sunflowers, we do not need to give it special light treatment for it to bloom normally, because as a short-day plant, it is not especially sensitive to light.

Although sunflowers are not sensitive to light, this does not mean sunflowers do not like ample sunlight. The seedlings, leaves and flower discs all have strong phototropism, so if you want it to grow healthily and vigorously, ample light is very necessary, as it can promote the growth of the plant, stems and leaves.

3. Temperature

Sunflowers are highly adaptable to temperature. They can grow in high-temperature environments and also resist a certain degree of cold. The seeds have strong low-temperature survival ability. At 2 degrees, the seeds can begin to germinate. The best temperature for germination is 31-37 degrees, and the maximum can be between 38-40 degrees.

However, it should be noted that in the cultivation methods and precautions for sunflowers, the most suitable growing temperature for sunflowers is 18-30 degrees, and the lowest temperature should not be below 10 degrees, otherwise its growth will be inhibited. Usually, the higher the temperature, the faster the development, but it is not recommended to keep it in a high-temperature environment for a long time.

4. Soil

Sunflowers can grow in various types of soil. Even dry land and saline-alkali land can be used for planting, because they have strong drought tolerance, salt tolerance and waterlogging tolerance. Even when the water content is as low as 8.8%, they can still grow normally, so they are very easy plants to keep alive.

5. Watering

Although sunflowers have extremely strong drought tolerance, we still need to water them appropriately, because as light intensity increases, water evaporation also becomes faster. Especially in the flowering season, water supply is even more necessary, so water needs to be replenished in time. Generally, it is enough to follow the principle of alternating dry and wet.

6. Fertilizing

In order to let sunflowers grow more healthily and make the flowers fuller and more beautiful, necessary fertilizing is very important. During the growing period, fertilize once about every 7-10 days. During the seedling stage, mainly use nitrogen fertilizer. After budding, use phosphorus and potassium fertilizer, which can promote the development of flower buds.

7. Pruning or transplanting

People admire sunflowers mainly for their yellow flowers, so during growth, excess side buds should be pruned, which can make it bloom more. 20 days after sunflower germination, spraying 89 solution can inhibit its growth height. If the plant is too tall, stakes can be used for support.

How to plant sunflowers, sunflower cultivation methods and precautions

Sunflowers are very beautiful flowers. They can not only bloom but also produce sunflower seeds for people to eat. I believe many people feel happy at first sight of a sunflower. Sunflowers have huge, bright and eye-catching flowers and dense branches and leaves, and are also novel potted ornamental plants. Do you know how to plant sunflowers? Next, let's take a look with the editor of Huayu Network at how to plant sunflowers!

Sunflower cultivation methods and precautions

1. Choose a suitable time for planting

Because there is a big latitude difference between northern and southern China, the temperatures in northern cities and southern cities are very different. The best temperature for seed germination is 24-28 degrees, and it must not exceed 30 degrees. Otherwise, if it is too hot, the seeds cannot handle it. So how do you plant sunflowers?

The growing period of sunflowers is 2-3 months. The temperature during the growing period should be above 28 degrees. If this cannot be reached, it is not suitable for planting. For example, even if the temperature in autumn is enough for the seeds to germinate, after germination it is already late autumn, so its growth needs cannot be met.

2. Sowing

The time for planting sunflowers was introduced above, so how do you sow sunflowers? Because they are sown from seeds. To ensure the success rate of germination, it is recommended to do this: tear half a paper napkin and soak it wet. Then put the seeds inside the paper napkin and cover them.

Loosen the soil in the small flowerpot prepared in advance, then put in the moistened seeds. Remember that the soil must not cover too much, only a thin layer, otherwise it will not have enough strength to sprout. Then adjust the nozzle of the spray bottle to the finest setting and sprinkle water evenly.

There is also another method: first wet all the soil in the small flowerpot prepared for sowing (this method is an informal method used by lazy people like me; the previous one is what is written in books), then similarly moisten the seeds in a wet paper napkin, and insert the melon seeds into the soil with the bottom facing up and the pointed end facing down. Then use a toothpick to push a little soil to cover the bottom of the melon seeds. Then spray a little water with a watering can.

3. Wait for germination

How do you plant sunflowers? Generally, after sowing sunflowers, you just wait for germination. Sunflowers sprout early or late. After sowing sunflowers, the next step is waiting for the day of germination. The germination time is about one week to 15 days. The time varies, depending on water, temperature, sunlight, soil and the vitality of the seeds. It is roughly like this.

During this period, in order to ensure sufficient water, after spraying water on the sunflower seedlings every day, give the flowers one hour of light, and afterward cover them with plastic wrap or a glass sheet, leaving only a small gap for ventilation.

4. Moving to a pot

For sunflowers, when the sprout is 1-2 cm and has grown cotyledons and true leaves, or in any case after 2 or 3 leaves have grown, it is time to consider moving it to a pot. Transfer it from the small pot used for germinating seeds to a larger pot. Of course, if you have enough flowerpots at home, I think it is also fine not to move it, so as not to accidentally injure the roots.

5. Ample light and fertilizer

I believe everyone has some understanding of how to plant them, and the rest is much easier. You should boldly give it enough light and put it under the sun. Water it every morning before the sun comes up, and remember to fertilize regularly. If it lacks sunlight, it will grow thin and long. A healthy sunflower should be thick, strong and powerful.

Continue growing leaves and basking in the sun until one day (probably after 1.5-2 months), you will find flower buds growing between the leaves of the sunflower. Remember to still keep fertilizing. The lowest leaves of the sunflower slowly turn yellow and wither, while the buds above become bigger and bigger, and finally bloom into beautiful sunflowers. Very beautiful, golden yellow.

How to grow sunflowers, sunflower cultivation methods

Sunflowers can be said to be a plant we are more than familiar with in our daily lives, but do you know how to grow sunflowers? Next, let's take a look at the cultivation methods of sunflowers.

1. Soil: Sunflowers do not have strict soil requirements and can grow in all kinds of soil, from fertile soil to dry land, barren land and saline-alkali land. They have strong saline-alkali tolerance.

2. Temperature: The suitable growing temperature is 21-27°C during the day and 10-16°C at night. If the temperature is low in early spring, the plant grows slowly, directly affecting the flowering time. If the temperature during the growing period exceeds 30°C and the temperature difference is too small, the stems and leaves are prone to excessive growth, and the flowering period is shortened.

3. Water: Sunflowers are tall plants with many dense leaves, and are a crop that consumes a lot of water. During the growing period, water in time, otherwise the leaves are prone to dehydration and wilting. However, it should not be too wet. If the humidity is too high, the basal leaves are prone to turning yellow.

4. Light: Sunflowers are short-day crops, but their response to daylight is not very sensitive. Sunflowers like ample sunlight, and their seedlings, leaves and flower discs all have strong phototropism. If it is continuously cloudy and rainy or grown in a semi-shaded environment for a long time, the stems will not be upright, the leaves will be soft, drooping and yellow-green, and the flower discs will be small and irregular.

5. Fertilizer: During the growing period, fertilize once a week, applying 800 times diluted multi-component compound fertilizer water alternately.

6. Cultivation: For potted plants, do not pinch the growing tip; single flowers are preferable. For potted tall varieties, 20 days after germination, spraying the leaf surface with 0.25%-0.4% B9 solution can control plant height. If grown for flowerbed viewing, pinch the growing tip once, and the branches can produce 4-5 flowers.
