How It Works
The plant with the fertilizer grew better. Plants grow better when they have all the nutrients needed to be healthy. Many different kinds of natural chemicals are found in soil that plants use to grow. When you add plant fertilizer, it adds extra nutrients to the soil which helps it grow best. Most of the fruits, vegetables and grains we eat are grown with fertilizer.
