The maintenance method of potted sunflower

How can you grow sunflowers at home? If you still hold this idea, you will out! The times are progressing, and now we have developed small ornamental sunflowers. Let's take a look at how to raise them.

Maintenance methods of potted sunflowers

Upper basin

If you sow sunflowers, the step of potting can be omitted. Flower friends can also buy sunflower seedlings directly to sow seeds.

Learn about the detailed sowing methods and read the article on how to grow ornamental sunflowers. The editor is lazy, omitting here. Temperature

Sunflowers have strong adaptability to temperature, like warm environment, but can also withstand low temperature, as long as the temperature is not less than 10 ℃, they can grow healthily.

The most suitable temperature for growth is 18: 30 ℃, 10: 18 ℃ at night, and the temperature difference between day and night is 8: 10 ℃, which is beneficial to the growth of stems and leaves.

In the suitable temperature range, the higher the temperature, the faster the plant growth; the lower the temperature, the slower the plant growth and affect the flowering.

When the temperature is too high, when it is above 25 ℃, pay attention to ventilation, and heat up when it is below 13 ℃.

Effect of Sunflower temperature

Light

Sunflowers are very sensitive to light and need plenty of light. Only when there is plenty of sunshine, the plant will grow healthily and the flowers will be bright and shiny. If you encounter continuous rainy days, the leaves droop and show yellowish green, and the size of the disk is uneven.

Watering

Sunflower has a well-developed root system, which is drought-tolerant but not drought-tolerant. When sowing to budding, the dry environment is beneficial to the growth and development of the root system, but with the increase of light and the acceleration of water evaporation, the plant needs nutrients to blossom and bear fruit. Especially in the flowering season, replenishing water can ensure the quality of flowers. Especially when the basin is small and big, it is necessary to replenish water in time and master the principle of "dry and wet".

Be affected by watering

Fertilizer application

Sunflowers like to be fattened and top-fertilized once in 7-10 days during the growing period.

Sunflower seedlings mainly use nitrogen fertilizer to promote the health of branches and leaves. After budding, the appropriate increase of phosphorus and potassium fertilizer can promote the development of flower buds and facilitate flowering. When the branches and leaves of the plant are thin and the leaves are withered and yellow, fertilizer should be added in time, otherwise ornamental sunflowers will lose their value.

Pruning

Sunflowers are mainly watched by the huge flowers on the trunk, so the extra lateral buds are trimmed in time during the growing period. But if you want to let it bloom more, you can pick the heart at the seedling stage to promote its branches, and there will be a flower in full bloom.

If the tall and large plant is selected, 89 solution can be sprayed on the leaf surface 20 days after germination to control its growth height. Overgrown plants can be supported by columns to avoid lodging.
