I agree with Will......mostly,

Do you really mean 1 tsp. of fertilizer per 2 cups of water monthly? The standard dilution rate is 1 tsp. per gal. A gallon is 16 cups! You are using a dilution ratio that is 8 times the recommended rate. Even then, I put 1/2 tsp. in a gallon of water, but I fertilize every 2 wk. in the spring and summer, and then use 1/4 tsp. in the fall and winter. I am no expert here, just have grown 100's of fiddles over a 25+ yr. period.
