This is my first year using wood chips. So on their third year was the first application. The wood chips are probably 4 to 6 inches. I applied them in winter to early spring. So this one is successfully emerging from the wood chips but I haven’t yet experienced what harvesting is like. I believe I had heard of someone even running chickens over them lightly in the fall after the ferns have died back for nitrogen but I don’t have chickens yet so I don’t know if that really works.
