Yuck! No bone meal supplements for me. I don't take any supplemental calcium due to recent discoveries of how it tends to get deposited in not-so-great places.
I have been loosening up soil in places where my fine top soil gets compacted. This spring, though, I'll have to disturb the top 6 inches with amendments. Then I'll add back the chop-and-drop debris on top along with some shredded leaves. Do worms re-use the same tunnels or are they always making new ones?
