I just use cattle feed molasses. Don't know if it is unfulfured or blackstrap.

The application rate is 3 ounces per 1,000 square feet. If you have 2,000 square feet, then put 6 ounces into your hose end sprayer along with as much water as you want to dilute it. Spray as evenly as you can until the bottle is empty and you're done.

Any hose sprayer or do you recommend one?

so any lawn sprayer. I purchased my molasses need to do my lawn before the garden.
