In your experiment, the experimental group would be the plants that get different amounts of the new fertilizer. This group is being tested to see the effect of the new fertilizer on plant growth, while the other groups (plants that only get soil and plants that only get water) serve as control groups to compare the results.
You are a scientist and would like to know if a new fertilizer will help plants grow faster. What would the experimental group be?
The plants that only get soil
The plants that get different amounts of the new fertilizer
The plants that only get water
