How to care for sunflowers after they sprout
Today, we will introduce how to care for sunflowers after they sprout and the correct maintenance methods for sunflowers after sprouting. Keep reading!
Sunflowers can be sown in spring and autumn, and they usually sprout within a week. After sprouting, they require ample sunlight and a suitable temperature for seedling growth. The temperature should not be too high or too low. After the seedlings grow for a while, they need to be pinched to prevent the plant from growing too vigorously, which may affect their appearance. Let's specifically introduce the following details.
1. Sunlight
Sunflowers need plenty of sunlight after sprouting. In the summer, when sunlight is intense, they should be shaded and not exposed to direct sunlight. They can tolerate scattered light. In winter, they can be placed in a bright and warm indoor environment for care.
2. Pinching
After sunflower seedlings grow 8-10 leaves, they can undergo pinching, where the top of the main stem is pinched off to prevent excessive growth and maintain a beautiful plant shape.
3. Temperature
After sunflowers sprout, the temperature should be kept around 20°C. If the temperature exceeds 30°C in summer, it is not conducive to seedling growth. Water can be sprayed to lower the temperature, or the plants can be moved to a shaded and well-ventilated area. In winter, they need to be moved to a warm place to avoid frostbite.
4. Watering and Fertilizing
Sunflower seedlings do not require much water and fertilizer. Keeping the soil moist during spring, summer, and autumn is sufficient. Watering should be thorough when the soil is dry, and avoid waterlogging. In winter, with lower temperatures, seedling growth slows down, gradually entering dormancy, so water should be controlled. During the growing season, diluted liquid fertilizer can be applied, using decomposed farmyard manure or cake fertilizer water, every 15-20 days, with frequent application of thin fertilizer to avoid fertilizer burns.
5. Improved Ventilation
After sunflowers sprout, they should be placed in a well-ventilated area to avoid long-term growth in a humid and confined environment, which can easily lead to diseases and pests. If diseases or pests are found, pesticides should be sprayed promptly for control.
The above is all about how to care for sunflowers after they sprout and the correct maintenance methods for sunflowers after sprouting. Have green plant enthusiasts understood this?
