Maintaining a clover and alfalfa wildlife plot adds to appeal and longevity. Depending on how much your plot is grazed in the summer, you may have to mow your plot to about 4-6 inches. It is best of you have a tool to catch your clippings. Mowing should be done when plants reach 12-14 inches tall. This will create fresh, new, tasty growth. Cut all plants to 4-6 inches high, do not mow when it is hot and dry.
