Should I stir (aerate) my vermicompost? (2024)

Hello Yoseph,

Good News!

Red wigglers (Eisenia Fetida) are probably "THE MOST" forgiving species of all composting worms.

Yes, you can disturb them but give them a little while and they'll be all nestled in again and it'll be business as usual.

There is no need to stir up any composting worm bin IF you have proper drainage and holes in the bottom and sides of the worm bin.

composting worms do a great job on their own of stirring up the compost this allows for the autonomous drainage/aeration of the contents in the bin.

If you do not want the compost mixed in with the cast then install hardware cloth in the middle of the bin and add food only to one side. When they are finished with one side (or almost) then you can put food in the other side etc... etc...

See my page on Worm bins:

As gasses (i.e. methane)are expelled from the top or top sides of any worm bin, Fresh anaerobic (oxygenated) air will be sucked in from the bottom.

If you do not have holes for any bin (this is extremely advised but not always necessary) then I would recommend stirring up the pot, so to speak, about twice a week.

You also mentioned that you have your worms in cardboard boxes. Hmm, not sure how long that will last as the worms really enjoy eating cardboard. They'll literally be eating themselves out of house and home ;-)

If this is just strictly for testing then okay, but if not and you are on a shoestring budget, then I would suggest using an opaque (non amorphous) 5 gallon bucket. Drill holes in the bottom and top lid for aeration and drainage.

If it still let's in too much light then spray paint the outside with black or cover the sides with a towel.

Let me know if you have anymore questions,
Pauly
