    For general purposes, 3 ounces of molasses per 1,000 square feet, four times per year (or season).

    Note that since I put it in these terms, you can dilute it with 1 pint of water, or 100 gallons of water - as long as 3 ounces get on every 1,000 square feet.

    There is a slight risk, if you want to call it that, of applying too much molasses. When the soil microbes get too much sugar, they go into a feeding frenzy and eat all the protein (nitrogen) they can get. This gives the temporary effect of binding up all the soil nitrogen so the plants don't get any. Once the sugar is depleted and nears the normal quantity, then that nitrogen is released again in the form of proteins from all the dead microbes. The amount of sugar needed to cause this temporary stunting effect is dependent on the nitrogen, sugar, and microbes in your soil. But 3 ounces per 1,000 should be far below the threshold of causing any problems.

    Has any one try appying molasses with a hose end sprayer, would it work or does molasses have to be tank mixed and aggitated?

  5. If turf is depleted of carbohydrates, ( ex. going in to summer with less the adequate reserve, and you have an extremely hot spell,) your turf may run out of carbohydrates and strave, so you can add a little molasse to feed the turf until it can manufactur its own carbohydrates again.
