I tried to save a terra cotta ( 1 gal?) pot of chives overwinter in a small patio shed. I brought the pot into the house about a month ago, watered it, and placed it under a grow light, but nothing has happened yet. Are my chives dead? Should they have sprouted by now if they’re still alive?
Plants are susceptible to winter kill if you don't keep them watered; the roots need that water to protect them. I think a month is ample time to get them to sprout. I would remove the plant from the pot and examine the roots. Live roots are somewhat fleshy; dead ones are withered.
