How to grow sunflowers to make them thrive
You may not be aware of the knowledge about how to grow sunflowers to make them thrive, as well as the care and precautions regarding green plants and flowers. Let's follow the editor to find out together!
The color of sunflower blooms is particularly bright, and they are extremely vibrant even in the hot summer sun. Sunflowers thrive in a sunny environment and only bloom when exposed to sunlight, closing during cloudy days or at night, hence the name "sunflower," which can also be called "noon flower."
The blooming period of sunflowers is from May to November, lasting a full half year. Seeing gardening enthusiasts posting their sunflowers on forums from May, many wonder: Why is your blooming period so long? Why do my sunflowers fade after a few days? Don't worry, let's answer these questions from planting to care one by one.
I. Light
Sunflowers are highly dependent on sunlight, and it can be said that their growth cannot be without it. They are especially suitable for cultivation in courtyards or on rooftops. Even when grown indoors, make sure to provide ample sunlight for at least 8 hours a day, otherwise the leaves will consume nutrients in vain, which is very detrimental to blooming. Keep the area well-ventilated during hot summer days without the need for additional shading.
II. Temperature
Sunflowers are not cold-resistant and grow most vigorously at temperatures between 25-30°C. High temperatures are fine, but if the temperature is low, the growth of sunflowers will slow down until it stops. Therefore, to ensure that sunflowers can survive the winter, it is necessary to keep them in temperatures above 10°C to prevent frostbite.
III. Watering
Sunflowers are drought-tolerant and do not mind dry soil and air, but they cannot tolerate overly moist environments. Therefore, the amount of watering must be controlled. Only during the hot summer days when water evaporates quickly should you increase the watering amount. Adopt the "moist when dry" principle, watering thoroughly each time and only watering when dry.
To prevent rapid water loss in the hot summer, avoid watering at the highest temperature of the day, which is noon. Instead, choose to water in the early morning or evening when the temperature and water temperature are not too different, to prevent sunflowers from suddenly encountering cold water in high heat, causing rapid withering.

IV. Fertilizing
Because sunflowers have a strong adaptability, there is no special soil requirement, but if you want the sunflower blooming period to be longer, you need to rely on fertilizing. During the growth period of sunflowers, apply a compound fertilizer once, and every half month before blooming, apply potassium or phosphorus fertilizer. This way, the sunflowers will receive sufficient nutrients, resulting in more and more vigorous blooms.
V. Soil Turning
If you want sunflowers to have an extended blooming period every year, soil turning is a task that cannot be overlooked. Every 1-2 years, you can thoroughly turn the soil or even repot, removing compacted soil and replacing it with new, loose, and fertile soil. After some root pruning and replanting, it can rejuvenate the sunflowers.
The pot for sunflowers does not need to be too large. If you want to extend the blooming period and achieve a full pot effect, a pot mouth of about 15 centimeters is usually sufficient. Also, make sure the bottom has drainage holes to facilitate sunflower drainage and prevent waterlogging.
VI. Pruning
When the new branches of the sunflower seedlings grow, pruning the top of the main branches can result in many new shoots. If you don't want sunflowers to grow too tall and think it might affect the appearance, you can control the height of the sunflowers by pruning the top. It will also make the overall plant more ornamental. When encountering leggy growth or reduced flower production, prune the old branches boldly, cutting to below 10 centimeters.
