Linda - your compost looks great! I'm at the level of worm population that I put scraps in all 4 trays. I have tried putting scraps in only the top tray, trying to encourage upward movement that I'm "supposed" to see but to no avail. I gave up worrying about it since the worms appear fine and I get compost. I drain the more liquid stuff in the bottom every week and dilute with rain water to use on the "needy" areas of the garden. I have been meaning to empty out the worm bin for the past month to get a good harvest of compost to put out before the leaves start falling. I might get two full harvests before fall.
