Help growing comfrey

[SI2305]

Hello,
I tried planting bocking 14 comfrey for my garden. All the literature says it should shoot out of the ground like a rocket with little to no help. My first group of 4 plants died in the soil and my second batch did start to take but recent rains have apparently turned wilty (we just had record flooding move through the area but the garden is on high ground). The soil is presently growing potatoes and onions and the comfrey itself is planted in manure.

If anyone has suggestions or experience I would certainly appreciate the input.

Thanks in advance

About half of my comfrey roots actually grew to maturity. I find it finicky to grow. Too much shade, or too much sun kills it. It also seems to burn up if not watered enough by myself or God
