What Happens When You Give Your Plants Too Many Nutrients
Over-fertilizing plants can cause nutrient burn, resulting in irreversible damage to the roots and leaves, thereby hindering the plants’ ability to photosynthesize and grow.
As a consequence of this nutrient overload, the leaves may develop crispy brown patches. These are the burnt areas that have lost the ability to absorb
energy from the sun.
Prior to reaching this critical stage, plants typically exhibit warning signs. The leaves may turn a deeper green and curl at the edges, and the tips may turn yellow and brown.
This happens because plants can’t store any excess energy obtained from fertilizers. Thus, when you give them too many nutrients, they experience nutrient burn.
