Reasons Why Marigolds Do Not Bloom and How to Fix Them

Marigolds are flowering plants, and once they fail to bloom, they lose their value. Many friends often encounter the phenomenon of marigolds not blooming during cultivation. So why do marigolds not bloom? How should this be solved? Let's take a look together.

1. Temperature too low

Marigolds prefer a warm environment, and only in a warm environment can they bloom normally. If the cultivation environment temperature is too low, then it will be difficult for their flower buds to form, and naturally they will not bloom. Therefore, during cultivation, it is best to ensure the environment is warm and keep the temperature between 10-20 degrees, which is beneficial for flower bud differentiation. Especially in winter, insulation measures must be taken well.

2. Improper pruning

Marigolds need proper pruning during the growing period, as this can promote the plant to produce more flowers, but pruning also has advantages and disadvantages. If pruning is improper, it can cause them not to bloom, or delay blooming. When pruning marigolds, mainly light pruning should be used. Before flowering, excess side branches can be thinned out, which can save nutrient consumption and concentrate nutrients so that the plant produces more flowers.

3. Insufficient light

When growing marigolds indoors, because light is limited, it often also causes them not to bloom. If the marigold's light duration is short and it is placed in a dark place for a long time, it will affect its flower bud differentiation and cause the plant not to bloom. At this time, it needs to be moved promptly to a place with sufficient light for care, but it should be noted that summer sunlight is strong, so appropriate shading is needed.

4. Insufficient nutrients

Marigolds will only bloom when nutrients are sufficient. During the care process, if nitrogen fertilizer is applied excessively, it will cause an imbalance in soil nutrients, resulting in poor plant nutrition and excessive vegetative growth, thereby inhibiting the plant from blooming. Therefore, when fertilizing, attention must be paid to the application of nitrogen fertilizer. During the flowering period, fertilization should mainly use phosphorus and potassium fertilizers, and nitrogen fertilizer should be applied as little as possible or not at all, to promote flower bud formation.
