Yesterday I was looking at a plant in pretty bad shape that I had bought a few months ago. The plant was indoors and the ceramic pot didn't have any holes at the bottom.
When I start looking at the soil I notice it has about five reddish worms in it. Here are some pictures of the soil and the worms. The soil did not have a single weed growing in it.
My question is: should I just dump this soil in the garbage? If it's reusable, then what can I do with the soil to prepare it for other plants?
