The failure of sunflowers to bloom is mostly caused by four reasons. The first is lack of light. It likes light very much. If it is in a dark environment for a long time, it will affect its growth and lead to no flowering. It should be exposed to more sun. The second is the lack of nutrients. If the soil is not fertilized for a long time, the soil will be poor and it will affect flowering. It is necessary to apply light fertilizer frequently. The third is improper watering. Long-term water shortage or too much watering will affect flowering. Replenish water according to actual conditions. The fourth is improper pruning, pruning too dense branches, excessively long branches, etc. in time.

1. Lack of light

1. Lack of light

The growth of sunflowers is inseparable from light. If the sun is not exposed to the sun for a long time during the maintenance period, it will affect the growth and flowering in a cool environment, resulting in no flowering. If it is caused by lack of light, you should move to a place with good lighting as soon as possible and get more sun. It is best to give it full day light. In an environment with sufficient light, it will accumulate more nutrients, so that it can grow vigorously and bloom as scheduled.

2. Lack of nutrients

The failure of sunflowers to bloom may also be caused by a lack of nutrients. More nutrients are consumed during the peak growth season and flowering period. It is best to topdress every half a month before flowering. Potassium dihydrogen phosphate foliar fertilizer should be applied once a month to promote smooth flowering and vigorous growth.

3. Improper watering

Although sunflowers have a certain degree of drought tolerance, if they are not watered for a long time during the maintenance period, it will hinder growth and affect flowering. If you find that the pot soil is dry, you need to replenish it with water in time. It is not tolerant to waterlogging, and watering it too much is detrimental to growth and may even cause root retting. It is best to water it according to the method of seeing dry and wet, and do not water until it is dry. The amount of watering should be controlled well, and it should be watered thoroughly every time without water accumulation.

4. Improper pruning

Sunflowers have strong germination performance and must be pruned in time during the maintenance period. If left unpruned for a long time, a large amount of nutrients will be consumed and the sunflower will not bloom. It is best to cut off leggy branches, thin branches, diseased branches, and dry branches in time to reduce nutrient consumption, promote more concentrated nutrients, and have better internal ventilation and light transmittance, so as to promote luxuriant branches and more flowers.
