Feed Your Worms

This page is about the various methods for feeding your worms. For questions about what to feed your worms, please visit our FAQ page.

The three feeding methods listed below exist to make the harvest of castings as easy as possible. They all do so by having you be a little strategic about where to place your food and bedding so that when it comes time to harvest, there will be little effort needed on your part to separate the castings from the worms and the not-yet broken down food scraps. If these methods feel overly complicated, don’t stress.  The main thing you need to remember is that every time you feed your worms, cover the food with plenty of dry bedding to soak up moisture and reduce pests.

Stacking Bin

Use the “lasagna method,” alternating between a layer of food and a layer of bedding. Start with your bottom most tray, which will be your first tray with holes on the bottom. Do not start your bin in the very bottom of your bin with no holes–this tray is intended for catching extra moisture or leachate. Continue feeding the bottom tray until it is full, and then put a new tray on top and continue with lasagna feeding: food, bedding, food, bedding. As the worms finish eating all of the food in the bottom bin, they will move through the holes to get to the new scraps in the next bin. The process of the worms migrating out of the bottom bin could take a few weeks, but after they all leave you will be left with a tray full of beautiful castings.

Single-layer Bin

If you have a small bin, use the “pocket feeding method.” That is, dig down into one corner of your bin and dump your food there and cover with dry bedding. For your next feeding, move a few inches over from your first feeding location and repeat. This way you will work around the bin, making harvest a bit easier later on.

If your bin is large enough, use the “section method.” The section method basically involves using the technique of the lasagna method (see above) in one section of your bin and then repeating it in another section once the first is full. As the worms finish all of the scraps in the first section, they will migrate to get the new scraps in the next section. By the time you’re done feeding the last section, the first section should be full of mostly worm-free castings. The number of sections you choose depends on how large your bin is. The most important part is that you have a system so you remember which sections have already been fed and which section you are currently feeding.
