    Generally a control is one that you are not using any of the tested material on. You want to establish normal growth, so that you can get accurate results from your variables.

    You would want to use a plant with no decomposing matter as a control, because you need to know normal growth without any extra fertilizer before you can determine the additional growth due to decomposing matter (like apple peel or potato peel).
