| All earthworms are beneficial to the soil. Unfortunately some introduced species are a bit too efficient in their activities and too prolific in their populations and create imbalances in the organic matter of some Northeastern native forests and woodlands, to their detriment. But in the home garden, all worms are beneficial and indicate a healthy amount of organic matter in the soil. I can contemplate all sorts of good reasons to screen compost and there is really no reason the presence of worms should deter you. The small ones will fall through the screening and larger ones can be tossed back into the pile or relocated to planting beds. It's all good :-) |
