Tag: Overfertilization

Nutrient lockout is one of the most common and frustrating problems for growers, often mistaken for simple nutrient deficiencies. Essentially, it is a chemical reaction that prevents plant roots from absorbing the nutrients you provide, starving them even when ample food is present.

According to the University of California's IPM program, excess nitrogen can cause plants to develop overly succulent leaves and shoots, increasing susceptibility to pests and root damage. If you've accidentally over-fertilized, knowing what to do if too much nitrogen is present can prevent serious, lasting harm to your garden.
