I received my order of a gallon of glycerine this morning and went right at the test. I first heated up water and poured it over the curling grass. The grass immediately rehydrated and straightened out! (So nice not to have to re-invent the wheel! Thanks to the late Dave Schwendeman) I mixed a half and half batch of glycerine and the warm water and submerged the grass into it. I will let it soak for a couple of hours, take it out, remove excess glycerine and hang it over the weekend. Monday will give me a good idea about whether this method will work to remediate the curling grass problem. I’m feeling hopeful!
