How to Plant Sunflowers
Let me tell you about how to plant sunflowers and introduce some sunflower planting techniques and methods in the field of green plants and flowers. Let's take a look together.
Sunflowers are also known as sun flowers. The functions of sunflowers are mainly divided into two categories: for consumption and for ornamental purposes. Sunflower inflorescences, seed shells, and stems can be used as feed and industrial raw materials, such as artificial silk, pulp, etc. The flower language of sunflowers is silent love, bright and passionate, symbolizing optimism, bravery, and relentless self-improvement.
Techniques for planting and managing sunflowers:
1. Soil
Sunflowers are not picky about soil and can quickly adapt to ordinary soil. However, it is best to provide them with loose, breathable, and well-draining soil for cultivation.
2. Sunlight
The more sunlight sunflowers receive, the better they grow. Make sure they get plenty of sunlight, even when the sunlight is strong in summer, there is no need to shade them.
3. Temperature
Sunflowers are not cold-resistant. The most suitable temperature for their growth is 26°C to 29°C. The cultivation temperature should not be lower than 15°C, and timely measures should be taken to keep them warm when the ambient temperature is too low.
4. Watering
Water sunflowers only when the soil feels dry to the touch, and be careful not to overwater to avoid积水 in the pot, which can cause root rot.
5. Fertilization
Sunflowers are relatively tolerant to poor soil, but they still need to be fertilized appropriately to promote their growth. You can fertilize them once every two weeks, using diluted phosphorus fertilizer, such as 0.1% potassium dihydrogen phosphate.
6. Pruning
You can pinch the top of the sunflower seedlings when they reach 3 to 4 cm in height. Also, pay attention to pruning the long branches, old branches, and weak branches. Proper pruning can promote the growth of sunflowers.
7. Diseases and Pests
Sunflowers have strong resistance and are less likely to be affected by diseases and pests. However, preventive measures should still be taken, and it is best to spray some preventive medicine on them before they germinate.
8. Cutting
Propagation of sunflowers often uses cutting. Simply insert the cut branches into the cultivation soil in an open-air environment, and the sunflowers will grow successfully without special care.
9. Seedling Management
Good seedling management is essential for sunflower planting to ensure the survival of all seedlings. During the sunflower planting period, it is not recommended to plant additional seeds. Instead, you can replace seedlings. thinning and replacing seedlings should be done when the first set of true leaves appear, and the final seedlings should be established before the third set of true leaves appear. If there are pests, spray pyrethroids or phoxim.
