A decomposable organic golf tee is provided, that is made of a compacted mulch material and water soluble adhesive, so that when inserted into the ground it will decompose after awhile to blend into the surrounding terrain. A modified decomposable organic golf tee is also provided, that contains a biodegradable support wall, plant food with grass seeds and a pair of wedges within, to help break up the tee when a downward force is applied thereto, so as to promote the growth of grass.
