Planting methods and precautions for sunflower seeds

Sunflowers are very adaptable to the environment, have gorgeous flowers, and have a very long flowering period. They are very popular among flower lovers. Many flower lovers plant a few pots of them on their balconies and courtyards every year for viewing.

Usually it takes about 2 months for sunflowers to bloom from sowing . As the temperature gradually rises, it is generally more appropriate to plant sunflowers around March . So now is a good time to sow sunflower seeds, so that they can bloom in large quantities in May or June.

①Soil requirements

Sunflowers have a strong ability to adapt to the environment and are not very demanding on the soil. They can grow even in ordinary garden soil .

However, in order for the seedlings to grow healthily, it is still necessary to use loose, fertile, and well-breathable soil. You can use some leaf mold, garden soil, or river sand, mix them evenly and put them into the flowerpot as culture soil.

②Sowing method

After filling the flowerpot with culture soil, mix the sunflower seeds into a small amount of fine sand . Because the sunflower seeds are too small, it is not easy to spread them evenly when sowing. Mixing with a small amount of fine sand can make them more evenly spread.

After spreading the seeds evenly, do not cover them with too much soil, otherwise it will affect the germination rate . You can sprinkle a layer of sand, just enough to cover the seeds, and then use a spray bottle to slightly wet the soil.

③Maintenance management

After sowing, sunflowers should not be placed in direct sunlight for the time being. It is best to keep them in a warm room. The temperature should be kept above 16°C . You can also cover them with a layer of plastic wrap, because the temperature in early spring is unstable and the seedlings are prone to frostbite.

Keep the soil slightly moist every day, not too dry and water-free, and small seedlings will grow in about a week . Then gradually place it in a place with scattered light so that the seedlings can grow and develop quickly.

④Transplanting

When the sunflower seedlings grow to about 8 cm, you can repot and transplant them .

First, fill the bottom of the pot with a layer of coarse sand or coal slag as a drainage layer, and then fill it with the prepared culture soil. Usually, we can add an appropriate amount of bone meal or organic fertilizer to the culture soil, so that the plant grows more vigorously and blooms more.

After planting, place the potted plants in a shaded place to allow them to grow slowly. After they are fully grown, gradually increase the light and start watering them with some dilute fertilizer to promote the growth and development of the plants.

⑥ Pinching and topping

During the growth process of sunflowers, it is necessary to pinch them appropriately, usually during the seedling stage .

When the plant grows to about 8 to 10 centimeters, cut off the top branches to allow it to sprout more side branches to increase the amount of buds and flowers.

Now as the temperature rises, many flowers and plants can be sown and propagated. If the outdoor temperature is still low, you can first grow seedlings indoors, and then gradually move them outdoors for maintenance after the weather warms up.
