Simply put, fertilizer burn is a condition that results in the burning or scorching of plant foliage. Fertilizer burn is the result of over fertilizing plants or applying fertilizer to wet foliage. Fertilizer contains salts, which draw moisture out of plants. When you apply excess fertilizer to plants, the result is yellow or brown discoloration and root damage. Fertilizer burn symptoms may appear within a day or two, or it may take a couple of weeks if you use a slow-release fertilizer.
