Worms are not okay for CP. Earthworms don't munch on the roots of your plant and can aerate the soil but it also releases the nitrogen locked up in the peat moss, changing the composition of the growing media. Their casting fertilizes the soil and increases the alkalinity, making it no longer suitable for your plant. YOu want to avoid both alkaline soil and fertilizing and Earthworms do both.

I strongly advice is to get rid of them whenever you see, I don't know how sometimes make their way in the peat moss, maybe the peat contains dormant egg worms.

Thank you, HK...
I never would have even thought about how an earthworm can change the soil...this is why I depend on this forum and the good people who answer my questions! Thanks again!

I don't kill the worms, I simply toss them on the flower bed or lawn. There's usefull their.
