I agree with Bananaman, especially since grass clippings are more of a compost than a mulch. Four inches thick of wood chips from healthy (non-infected) branches are a better choice. Try for a chip size of 1-inch width -- if you are buying them, then ask for fine-texture wood chip.
By the way, Fish Emulsion (typically 4-1-1) is a great product but one of the most expensive sources of Nitrogen for your plants you can buy (about $55 per net lb of Nitrogen). I would use it as a soil amendment and source of micronutrients about 2 or 3 times per year -- just as someone might use seaweed extract for the same purpose. For natural and "organic" sources of nitrogen and potassium, you should be able to get the cost below $10 per net lb of nutrient.
