It's hard to find a fertilizer with natural potassium. Enter----> comfrey. It's full of potassium (3 times that the amount in organic manure), an essential for veggies and other plants to grow and fruit to their full potential. Comfrey is also high in calcium, nitrogen, phosphorous, & potash. The perfect mix for fertilizing your garden organically!
I have Russian Comfrey, Bocking 14. This is a sterile plant. It doesn't re-seed itself. Thank goodness! At the rate this stuff grows, I can certainly see how it could get out of control if it did re-seed itself. It is also one of the most potent comfrey plants in medicinal terms, which is why I grow it- to make healing salves. Who know it healed plants too!
First, I made comfrey tea. This is how:
Fill a five gallon bucket with comfrey leaves. Pack it tight. Then add water to cover the leaves. If you ferment anything, same concept (without the sugar). Place a lid on the bucket or piece of wood. I prefer the wood piece because I hate trying to get those tight lids off without spilling. Leave outside, in the sun for a week +. It creates this slimy, sludgy, bubbly green tea. Use this as a liquid fertilizer. 1/2 cup will make all the difference in the world for new and old plants :) You can dilute as well if you don't want it as potent.
