Have you ever realized that there are many uses for the cardboard egg carton. One great use I found for it is a seed starter for a garden. Why? Because once the seed begins to sprout and turn into a shrub, you must plant it in the ground and the cardboard egg carton is biodegradable which means it will break down in the soil.
Therefore, you will not need to uproot your shrub and re-plant it, simply cut out each egg socket shrub and plant it directly into the ground.
