Becky I use a lot of pine fines myself because of the sandy soil, I add a couple inch's of pine fines every time I rework the beds.
Stan, the seedling beds only get alfalfa once and its tilled in, the hybridizing beds get it twice, tilled in when I rework the bed and again when I add the plants to the bed. I have found that those small seedlings don't need as much of anything as the older plants.
