1st aid needed!
I had a really productive bin for the past year. Went on vacation and came back to rock hard bedding. I thought I had watered my kitchen bin before I left but guess not. I have a wood multi tray bin....found a few hearty souls in the center....about 2% of what was. I broke up the chunk, watered, layed moist cardboard on top, and added a cut up banana peel.
Any tips to "resuscitate" my wormie population? Any special food or other additives that they particularly love? Any mineral additives? Thanks in advance for any help!
