How to make sunflowers bloom more? Why are the flowers so small?

1. How to make sunflowers bloom more

1. Light: If you want sunflowers to bloom more, the most important factor is more light. Sunflowers like sunshine, and if there is a lack of light, the plants will bloom less or even not bloom. Therefore, if you grow sunflowers at home, you must expose them to more sunlight, and there is no need to block them even in the summer sun.

2. Temperature: After the sunflowers are planted, they will bloom in about a month in an environment of about 20°C. However, if the maintenance temperature is low, the growth rate of the sunflowers will slow down, and the flowering time will be delayed, resulting in late flowering and less flowering.

3. Watering: Sunflowers are drought-resistant, but in order to make the plants bloom more, it is best to choose loose and breathable soil for planting, keep the soil moist, and water it thoroughly when the soil surface turns white and dry to ensure that the plants are not killed by drought in the summer sun.

4. Fertilization: Sunflowers do not need too much fertilizer and water, but if you want the plants to bloom more, you can apply thin fertilizers frequently. For example, during the growth period of sunflowers, irrigate them with fertilizers and water with a balanced content of nitrogen, phosphorus and potassium. Before flowering, switch to phosphorus and potassium fertilizers, irrigate them once every half a month, and the concentration should be light.

2. Why are sunflowers small?

After the domestic sunflowers bloom, the flowers are very small, mainly due to the following reasons. The first is a problem of variety, so you can only accept your fate. The second is insufficient light, so find ways to increase the light. The third is that the maintenance temperature is too low, so find ways to increase the temperature. The fourth is lack of nutrition, which can be improved by appropriate fertilization.
