I've read that comfrey leaves will help with preventing scab on potatoes? Does anyone have any experience with this, and its success or lack there of?
Also, how would you apply it to a raised bed garden? Mix it throughout the garden at a specific depth, or simply lay it around the seed at the time of planting? Grind it down and apply powder to soil, or in a tea compost?
Looking for some thoughts on it.
Thanks in advance!
