When do plant nutrient needs gradually increase?

The seedling stage is a critical period for plants where nutrient absorption is essential for establishing strong roots and initial growth. Nutrient needs during this stage begin to increase as the plant develops its first true leaves and starts to photosynthesize. While plants do require some nutrients early on, their overall nutrient demands will gradually rise as they transition into more advanced growth stages.

In contrast, during vegetative growth, the nutrient requirements are generally high as the plant is rapidly developing leaves and stems. The reproductive growth stage sees an even further increase in nutrient demand due to the energy-intensive processes associated with flowering and fruiting. Dormancy, on the other hand, typically involves a significant reduction in nutrient uptake as plants conserve energy and resources.

Thus, while the seedling stage marks the onset of increasing nutrient needs, it is also understood that nutrient demands will continue to rise with the plant's developmental progression.
