Gardening Questions #002 – How Many Trays to Use When Starting a Worm Farm?



When setting up a worm farm vermicomposting system, how many trays should I start with?

Most of the worm farms that are sold at garden centres use a stackable tray design, and when first starting, use only a single tray. When the first tray is full, when the contents reach the fill line on the inside of the tray, then add a second tray.

It takes a while to fill a tray, as the food that’s added disappears in a few days, and the level drops back down. When the food is converted to worm castings, the level in the tray doesn’t go down anymore, and that’s when a new empty tray is stacked on top of the existing one.

    Love it. I use a fairly basic worm farm that I built from an old bathtub, and keep out of sight near my apartments veggie patch. I basically just keep adding to it and the worms munch it down. I didnt have much luck at all with my store bought layered kit so gave up onthat one after a few months and went the ‘whole hog’ with the bathtub
