Dave/Trish - You'll get a chuckle out of this story that happened today .....
I was removing a small Brugmansia tree from an 18 gallon plastic bin that I had it growing in. I didn't like the tree shape which was leaning way over and it would not sprout new shoots to grow the way I wanted it to, so I took some cuttings and dumped the rest into the pile along our property line. I flipped the container upside-down to remove the Brug stump and roots and all the soil that was attached to it. Upon dumping it, the bottom soil was now on top of the pile and I could see earthworms!!! I picked out 12-13 earthworms from that bin soil! How they got in there I don't know, but the bin had only been out there about 4 months. I had been wondering about the topsoil I've been purchasing and spreading around as well as using in several Brug containers. I wasn't sure if it was very good because it was cheap in price. Well, the worms in that bin using that topsoil now have me convinced that it IS good stuff! LOL! I've never seen that many earthworms in any area of my ground soil. So what does that tell me?! I have really horrible ground soil and .... cheap topsoil used in a plastic bin is the only thing attracting earthworms in my yard! How sad is that????!!! (sigh)
I need to watch some YouTube videos on how to make my own worm bins. I really should do something more to improve my dirt. I WANT EARTHWORMS IN MY YARD!!!!!
