Comfrey is a goodie. Get the sterile one, Symphytum Officinale (common comfrey), which is propagated by the root. The tap root goes down deep into the soil to bring up the nutrients to nearby plants. Plant it under your fruit trees with some flowers that attract beneficial insects.
You can also steep the leaves in water for a health tonic for your plants.
These new plants are going in client's orchard this week.
