Fertilizer burn occurs when plants are damaged by excessive application of fertilizer, leading to browning, wilting, or death of the plant tissue. The high concentration of nutrients, particularly nitrogen salts, can "burn" the roots and foliage, preventing the plant from absorbing water properly. To avoid fertilizer burn, it is important to follow recommended application rates and dilute fertilizers as necessary. Over-fertilization can result in lasting damage to plants and soil health.
