earthworms vs garden tilling
o i would like to till in some leaf mulch for my garden. i had to remove some thistles first with a spade. There are a bunch of nice sized earthworm, some about nightcrawler size. i know these are good for the soil. If i till with a machine i will destroy some of the worms. Will it matter or do they repopulate easily? When i have turned over some soil and find them on the top i put them back in the cooler dirt and cover them thinking i am helping them survive. Is this the wrong thing to do? Thanks for your worm info! o
