Sunflower cuttings methods and precautions.
Sunflower is a beautiful flower, colorful flowers can bloom from summer to autumn, it can be said to be a proper flowering machine, and it is very solid and easy to raise, the propagation method is also very simple, just cut a small section of cuttings, today I will share with you a few cuttings of sunflower cuttings methods and precautions.
First, the time of cuttings.
The best time to take cuttings is in spring and autumn, when the climate is suitable and the temperature is moderate, which is conducive to the rooting and growth of shoots. Summer cuttings are also fine, but you need to pay attention to sun protection and moisturizing.
2. Choose cuttings material.
Choose healthy, stout, pest-free shoots for cuttings, the length of the branches should be controlled between 8-10 cm, and 2-3 leaves should be retained. Some nodes should be reserved on the cuttings to facilitate rooting.
3. Prepare the soil.
The soil texture of cuttings should be breathable and permeable, and you can choose a mixture of vermiculite, perlite and other materials. At the same time, the soil should not be too sticky and heavy, so as not to affect the rooting of the branches.
Fourth, the method of cuttings.
1. Use chopsticks or a small wooden stick to insert a small hole in the soil to a depth of about two-thirds of the length of the branch.
2. Insert the branches into the small holes, make sure the branches are stable, and then gently compact the soil.
3. Water thoroughly and keep the soil moist.
5. Post-maintenance management.
1. Put the cuttings in a ventilated place, not directly in the sun, because the roots do not grow well, and the strong light will cause the branches to dehydrate and wiltWait for about 1 to 2 weeks, if the cuttings have new leaves to grow, which proves that the roots are good, you can move to a location with astigmatism, as the number of leaves on the branches gradually increases, you must move to a place with sufficient light, otherwise the branches will grow.
2. In the process of growing up seedlings, it is necessary to pay attention to the supplement of water-soluble fertilizer. When the branches and leaves are constantly growing, you can choose Hua Duoduo No. 1;When breeding flower buds, fertilizers with high phosphorus and potassium should be applied to promote flowering, and you can choose Hua Duoduo No. 2 or potassium dihydrogen phosphate.
3. Adopt a dry and thorough watering method. Observe the soil before watering, and find that the soil is dry before watering, or you can use the weight of the pot, if you feel that the pot is lighter, it is a lack of water, then immediately replenish the water. It should be noted that sunflowers are very drought tolerant, but not waterlogging, so the soil should not be kept moist for a long time to avoid root rot.
4. Sunflower is heat-resistant but not cold-resistant, when the temperature is lower than 5 degrees, Sunflower is easy to freeze to death. In winter, if the outdoor temperature is kept below 5 degrees for a long time, it is recommended to maintain it indoors, and then move it outdoors when the temperature rises.
5. Sunflowers are very light-loving, and the more they are sunned, the better they grow and the more they bloom. If there is not enough light, the sunflower will have long branches and little or no flowering.
In short, sunflower cuttings need to pay attention to details and maintenance management, only by doing these jobs well, can sunflower grow and reproduce quickly and show its beautiful flowers.
