What happens in winter?
In zones 6 and lower, what happens to the late fall organic fertilizer and finely mulched leaves in Dec thru Feb? I understand microbial activity drops off with soil temps in the 40's. I have lots of mulched leaves on the lawn and several sacks of Starbucks coffee grounds ready to spread. Are these things still working to improve the soil during the winter months? Can compost be spread in winter? Does shredded leaves break down? In other words, what's my lawn doing now and what does the organic lawn guy do in the winter to get a head start on spring growth?
