What do the three macro nutrients do for the plant?

The three macronutrients essential for plants are nitrogen, phosphorus, and potassium. Nitrogen promotes healthy leaf and stem growth, enabling robust photosynthesis. Phosphorus is crucial for root development and energy transfer within the plant, supporting flowering and fruiting. Potassium aids in overall plant health by regulating water uptake, enhancing disease resistance, and improving the quality of fruits and vegetables.
