How to Plant Sunflowers
Today, I will explain in detail how to plant sunflowers and the precautions for raising them, a topic related to flower cultivation. 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 flower spikes, seed shells, and stems of sunflowers 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 perseverance.
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 give them loose, breathable, and well-drained soil for cultivation.
2. Sunlight
The more sunlight, the better sunflowers grow. Make sure they get plenty of sunlight, even in the intense summer sun, there is no need to shield them.
3. Temperature
Sunflowers are not cold-resistant. The most suitable temperature for their growth is 26℃~29℃, and their cultivation temperature should not be lower than 15℃. Promptly keep them warm when the ambient temperature is too low.
4. Watering
Water sunflowers only when the soil is dry and when it feels wet. Never overwater to the point where积水 accumulates in the pot, as this can cause 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半个月, using diluted phosphorus fertilizer, and it is recommended to use 0.1% potassium dihydrogen phosphate.
6. Pruning
You can pinch the top of sunflower seedlings when they are 3cm~4cm tall, and also pay attention to pruning the sprawling branches, old branches, and weak branches. Moderate pruning can promote sunflower growth.
7. Diseases and Pests
Sunflowers have strong resistance and are rarely affected by diseases and pests. However, preventive measures should still be taken, and it is best to spray some preventive drugs on them before they germinate.
8. Cutting
Propagation of sunflowers is often done by cutting. Just insert the cut branches into the cultivated soil and grow them in an open-air environment. Sunflowers can survive without special care.
9. Seedling Management
Good seedling management is essential for sunflower planting to ensure full seedlings. During the sunflower planting period, it is not recommended to replant, but you can replenish seedlings. Do the thinning and replenishing when the first set of true leaves unfolds and complete the seedling establishment before the third set of true leaves unfolds. If there are pests, spray pyrethroids or phoxim.
The above introduction to how to plant sunflowers and the precautions for raising them is hoped to be enjoyed by everyone!
