Since I harvested the bottom tray of my worm bin, it was the perfect time to set up a new tray for my worms.
For my worm bedding, I have been using coconut coir fiber. The coir comes in a compressed block about the size of a brick and is made from coconut husks. It has a high water holding capacity and can hold up to 10 times its weight. I buy mine at my local nursery, Talini’s, for $2.99. The compressed brick expands when you add water so you really only need one. Just put it in a bucket, fill with a generous amount of water and enjoy the endless entertainment of watching something absorb water (I wish coconut coir would follow my daughter around whenever she drinks anything). Wait until the center of the brick has absorbed water. You can always wring out excess water if need be.
I also like using shredded newspaper to add on top of the coir. The worms seem to really love the newspaper. Since I don’t subscribe to a newspaper, I save my Inside East Sacramento newspaper to shred for my bin.
