The fun of growing vegetables, flowers, shrubs and trees from seeds and cuttings is so rewarding. But, flower dropping can ruin all these fun, when plants don’t grow or show the same vigor.

Reason for flower dropping:

A. Irregular watering

B. Nutrient deficiency

C. Improper pollination

D. Natural sinensis

E. Hormonal variation

Irregular watering: water is basic unit of plant life, it constitute about 95% of plant body, hence there is need of regular watering, when there is gap in irrigation interval, some of the psychological process of the plant will get disturbed. To overcome this situation, the plant get adopted to some stress measures likehormone synthesis, reduced photosynthesis where this phenomenon hit the flowering condition of the plant. This serve as one of the major reason for flower dropping.

Nutrient deficiency: plant require about 17 essential nutrient for their perfect and healthy life cycle completion, the variation of any nutrient could be observed through deficiency symptoms. Each nutrient has their own key role in the plant life cycle. Among them one of the nutrient named by boron will play a major role in flower setting, pollination, fruit setting so when there is decreased level boron, you could notice the heavy flower dropping.

Improper pollination:in floral world, there is no history of conversion of 100 percent flowers into fruits. Out of 100 flowers, you can expect only 40 percent flowers that gets converted into fruits. But in other cases when there improper pollination (the pollen get fail to fertilize the ovary of the flower), the flowers easily get detached. Especially in case of creepers (cucurbit, gourds, melons) the plant has unique flowering habit, which is both male and female flowers are located in different part of the plant. Once the pollination process completed the male flowers stat to fall-off, as this is natural phenomenon there is no need to take a worry.

Hormonal variation:whenthere is abiotic stress for the plant like, warm temperature, water stress and hard soil in response to that the plant body get reacts and produces some hormone like abscisic. These hormone help the plant to overcome some physiological stress in turn these hormone also   produces some acid which is cause for flower dropping.

Natural sinensis: this type of flower dropping you can expect when there is loads of flower on particular branch. In such situation there is lot of competency among the flowers for nutrient, air and space. At that point the theory like survival of fitness works means the flower, which is strong enough will survive and turn into a fruit.

HOW TO OVERCOME:

1. Regular interval of watering
2. Right time application right diet(nutrients)
3. Ensure proper pollination
4. Encourage the pollinating organism
5. Avoid the abiotic stress on plants
