You have only one independent variable -- giving or not giving the fertilizer -- with the experimental group getting the fertilizer. the height of the plants is the dependent variable.
As much as possible, you want to match the two groups according to other variables that effect growth (e.g., watering, sunlight, seed quality, etc.).
I hope this helps a little more. Thanks for asking.
