What is the planting method for sunflowers?
A bit of knowledge to share with you about the planting method of sunflowers and the explanation of the planting season 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: edible and ornamental. The sunflower spike, seed shell, and stem 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 warm, symbolizing optimism, bravery, and perseverance.
Planting and management techniques for sunflowers:
1. Soil
Sunflowers are not picky about soil and can quickly adapt to ordinary soil, but it is best to give them loose and breathable soil with good drainage as the growing medium.
2. Light
The more sunlight sunflowers get, the better they grow. Make sure to provide them with plenty of sunlight, even when the sun is strong in the summer, there is no need to shade them.
3. Temperature
Sunflowers are not cold-tolerant. The most suitable temperature for their growth is between 26°C to 29°C. The cultivation temperature should not be lower than 15°C, and timely insulation should be provided when the ambient temperature is too low.
4. Watering
Water sunflowers only when the soil is dry to the touch and avoid overwatering to prevent积水 in the pot, as this can lead to root rot.
5. Fertilizing
Sunflowers are relatively tolerant to poor soil, but they should still be fertilized appropriately to promote growth. You can fertilize them once every half month, using diluted phosphorus fertilizer, with a recommendation of 0.1% potassium dihydrogen phosphate.
6. Pruning
You can pinch the top of the sunflower seedlings when they reach 3cm to 4cm in height. Also, pay attention to pruning the long, old, and weak branches. Proper pruning can promote the growth of sunflowers.
7. Diseases and Pests
Sunflowers have strong resistance and are less 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 growing medium and cultivate them in an open-air environment without special care, and the sunflowers can survive easily.
9. Seedling Management
Good seedling management is necessary for sunflower planting to ensure full seedlings. During the sunflower planting period, it is not recommended to replant, but seedlings can be supplemented. The thinning and supplementation should be done when the first pair of true leaves unfolds, and the final seedlings should be established before the third pair of true leaves unfolds. If there are pests, spray pyrethrin or phoxim.
