Plant sunflowers in March, pay attention to several details, high seedling rate, and vigorous plant growth
Sunflowers are highly adaptable to the environment, with colorful and beautiful flowers, and have an extended blooming period, making them a flower loved by many flower enthusiasts. Every year, they plant several pots on their balconies and courtyards for appreciation. It usually takes about two months from sowing to blooming for sunflowers. Now it is March, and the weather is getting warmer, so those who like them can start sowing and propagating. By May to June, they can bloom in large quantities.
I. Soil Requirements
Sunflowers have a strong adaptability to the environment and are not strict about soil. They can even grow in ordinary garden soil. However, to ensure robust seedlings, it is still necessary to use loose, fertile, and well-ventilated soil. You can mix some decayed leaf soil, garden soil, and river sand and then put them in flowerpots as growing soil.
II. Sowing Method
After preparing the growing soil in the flowerpot, mix the sunflower seeds with a small amount of fine sand because sunflower seeds are too small and difficult to spread evenly. Mixing with a little fine sand can help spread them more evenly. After spreading the seeds evenly, do not cover them too thickly with soil, as this can affect the germination rate. Sprinkle a layer of sand to just cover the seeds, and then spray the soil slightly moist with a spray bottle.
III. Maintenance Management
After sowing sunflowers, do not place them in direct sunlight. It is best to keep them in a warm room at a temperature above 16°C. You can also cover them with a layer of plastic wrap because the early spring weather is unstable and can easily freeze the seedlings.
Keep the soil slightly moist every day without letting it become too dry. In about a week, small seedlings will sprout, and then gradually move them to a place with scattered light to promote rapid growth and development of the seedlings.

IV. Potting and Transplanting
When the sunflower seedlings grow to about 8 centimeters, they can be transplanted into a new pot. First, prepare the bottom of the pot with coarse sand or coal cinder as a drainage layer, then add the prepared growing soil on top. You can also mix in some bone meal or organic fertilizer to make the plants grow more robust and produce more flowers.
After planting, place the potted plant in a shaded area to acclimate the seedlings. Once fully acclimated, gradually increase sunlight exposure and start watering with some dilute fertilizer to promote plant growth.
V. Pinching and TopPING
During the growth of sunflowers, it is necessary to pinch them appropriately. Usually, this is done during the seedling stage. When the plant grows to about 8 to 10 centimeters, cut off the top branches to encourage more lateral branches and increase the number of flower buds.
Now, with the rising temperatures, many plants can be sown and propagated. If the outdoor temperature is still low, you can start seedlings indoors and then gradually move them outside when the weather warms up.
