Using tea as a fertilizer?
I have been reading lately about how people use tea as a fertilizer for their plants. I have read about using brewed, diluted tea that has cooled down to water the plants, mixing the used tea leaves into the soil, etc.
My question is can you use any tea for this? Most of the information I have found only mentions Green Tea but I drink a lot of fruity teas (blueberry, raspberry...) would these work just as well?
Thanks in advance!
