Typically, too much of any commercial fertilizer kills plants because they are salt based products. The imbalance of the natural chemicals within the plant leads to it wilting or dying if the situation is not repaired.

Most commercial fertilizers have salt and other chemicals to help feed plants. Even though most plants require sunlight and water, they also need a reliable food source. However, just like humans, if a plant eats too much, it causes health concerns that need to be addressed promptly. Luckily, it is easy to start a routine for most gardens by using fertilizer on a weekly basis. Unlike other living things, plants can survive on a much smaller diet. The type of fertilizer is also a big concern, because some chemical compounds are not great for vegetables, fruits or exotic flowers. Learning about the types of fertilizers that work best for a particular plant is very important, especially since some plants only need to be fed on a bi-weekly or monthly basis. Another factor to consider is that since the main ingredient in fertilizer is salt, it has a tendency to make plants to wilt. This happens because it causes an imbalance in the salt, sugars and water levels of the plant and if not repaired it leads to the plant eventually dying.
