This tea works good for me.

Alfalfa Tea for Fertilizing Potted Plants 2 cups Alfalfa pellets in 5 gal bucket. Fill bucket with warm water, let sit for 15 min. Stir, dip pitcher in bucket and pour on the plants. The pellets expand and the alfalfa sinks to the bottom of the bucket. Fill again with water. Keep refilling the bucket with water and stirring until you have used up the alfalfa.
