Here’s a little look at a recent tomato experiment; with and without castings. We used 25% worm castings mixed with cheap potting soil for seeding. When we transplanted into larger containers, we used the same percentage, just in larger pots. Lastly, when we planted we used about one cup of worm castings in each hole. Here’s some pics that tell the story. Admittedly, it isn’t perfect controlled science, but it is certainly empirical evidence.
First is a photo of our seeding tray with and without castings. The wet/dark looking soil is with 25% castings. By the way, you have to be careful not to just accept that there is moisture in there just because it is dark. That is the nature of vermiculture. Touch it to make sure.
Next is a photo of the seedlings as they were growing. The one on the left is without worm castings and the one on the right is with castings. Everything else is the same. Except … the one with the castings, on the right, is actually one week younger.
Lastly, here is a photo of the tomato beds as they were maturing. (My shadow taking the picture is just thrown in for your viewing pleasure and because I am a lousy photographer.) Sorry about that.
The bed on the left has the plants where we put one cup of worm castings in each hole when we planted. The bed on the right does not have vermicompost. Everything else was the same. Same soil to begin with, same watering schedule and amounts, same weather, etc. You’ll notice how much taller and fuller the plants on the left are. Three cheers for our wonder worms and their worm castings.

Thanks for taking the time for a look see. Why not do your own experiment?
