RE: Do you want to make your own natural liquid fertilizer? One that is especially rich in potassium and perfect to encourage flowers and fruit set?

Not sure if borage leaves will do similar. I guess you won't know until you try. Comfrey is known to accumulate nutrients on the leaves and that's why it is so effective. You can eat the leaves. I use the flowers to make tinctures, but have never actually just eaten the flowers. I am sure you can eat it, but should probably check or only eat a small amount at first.
