I planted various herbs (mint, oregano, parsley, thyme) in the holes of the cinder blocks which make up my garden bed. I am planning to move those blocks to a different location. How early is too early to disturb the roots of my herbs? I'm afraid of killing them or damaging them to the point where a little cool weather might get them. I don't plan on removing the herbs from the blocks, but I know they have grown into the ground a little as well. Any tips? This will be only my second year gardening so I could use advice!
