Plants, at any stage, whether flowering or bearing fruit, will need nutrients at some point for their optimum health and prosperity. They generally need 17 important elements for the growth and survival of the plant. Each element has a specific function it performs on the plant.

These nutrients are basically divided into two groups; micronutrients and macronutrients. Nutrints are not limited to specific plant species or crops, but to a variety of horticultural processes in various conditions including propagating, hydroponic growing and in greenhouses. 

Farmers are also advised to apply various plant nutrients to their crops or when symptoms of particular problems, infections or malnourishment are shown by the crops.
