When is the best season to plant sunflowers?

Sunflowers must be familiar to everyone. As long as the temperature rises, it can bloom gradually until winter comes. The flowering period is very large If you have a yard, you can plant a flower sea. The key is that its maintenance is very simple, but many people want to raise sunflowers, but they don't know how to get them and how to cultivate them. March is the season for planting sunflowers, because the temperature rises gradually. Qi teaches you two cultivation methods, and you can easily create a sea of flowers as long as you operate them properly.

1, sowing

Sunflowers can bear seeds, but most of the seeds we buy are single-petal sunflowers, because double-petal sunflowers can't be pollinated in the middle, and single-petal sunflowers can be pollinated by wind or insects, so they can bear seeds. We can buy some seeds of single sunflower with our favorite color and bring them back to sow in March, but we must remember to sow according to the temperature when sowing. Sunflowers are not cold-resistant, so we should ensure that the minimum temperature is above five degrees, so that seedlings can emerge quickly and grow faster through sowing. Because the lowest temperature is five degrees at night, you can see light during the day, and the temperature must be above ten degrees before he can germinate normally.

If you want to sow, you can choose potted plants or ground planting methods. Whether it is potted or planted in the ground, we must remember to thoroughly water the flowerpot or the soil in the field before sowing, and then spread our sunflower seeds evenly on the soil surface and cover it with a thin layer of soil. Remember, the soil must be thin. If you are afraid of not sprouting with a thick layer, you can sprinkle a thin layer of vermiculite or river water. The river sand should be covered with fine particles. Because the bottom is wet, the soil on it will slowly absorb water and get wet, and then put it in a visible place. As long as the temperature is right, you will find that it can grow quickly in seven days at most.

When the seedlings grow up, they must get enough light. When they grow to a certain height and look crowded in flowerpots, we can space the seedlings and transplant the extra seedlings into other flowerpots, so that they can become multiple flowerpots at once. Sunflower seeds need two or three months at most from emergence to growth, and they can continue to bloom during the growth process. If you want to blossom more, when his seedlings are small in the early stage, if the branches grow to the top, you will grow enough side branches, and one tree will grow a big pot.

2. Cutting

Many sunflower varieties are perennial. The so-called perennial is winter, as long as the temperature is not lower than five degrees, it will not freeze to death. You can buy some sunflower branches. For example, we like double petals. We can't sow. Buy some sunflowers with double petals. A branch is very cheap, and a few dollars can buy a bunch of branches. After the branches are bought back, you must choose the lowest temperature when the temperature is above five degrees.

If the cuttings are long, we will cut them into small pieces of more than three centimeters. After cutting, we will leave a space to insert them into the flowerpot and into the ground. Water is poured directly once to ensure light and ventilation. Rooting begins in a week or so, and germination can be clearly seen in two weeks. When the branches grow, you can pinch them off and insert them into the soil, so that your whole flowerpot will be full at once. When it is full, you can let it bloom once and continue to grow and bloom later.
