( That explained it... It was sad to think that the Green Knight's attack could have done so much damage, but it wasn't irreversible. )

I see... That's not a difficult thing to fix. If you've only just recently moved them, then giving them a lot of water can help them re-adapt to the new soil. You can also try to reloosen the soil around it and try again with new soil if that doesn't help. As long as you don't overwater them, it should be alright.
