My wife planted cilantro in the garden. She is a plopper. No fertilizer underneath, just dig a hole. I had put out 12-12-12 when I tilled but that was quite a while back. It struggled, I fertilized, it has gotten better. two or three different shaped leaves now, and flowers. It will be interesting to know the outcome of all this.
I agree with Carolyn,, the bed is just still too hot ! But if you are having the same rain we are,, I would just leave it alone and wait for it to balance out ! I would never use any manure bought from the big box stores for vegetables ! Its fine for flowers but not edibles !
I have no clue if using Epsom salt around the plants will help. I only know we use a measured amount around peppers and tomatoes and cucumbers.
