I have a flowerbed area that surrounds my house that is covered with pine straw. I have dug a trench around edge of flowerbed and cover the trench with the pine straw. There is no border between yard grass and pine straw. For the grass that grow runners along top of the pine straw, what would be the best way to keep the area edged? I am trying to use least expensive way possible. I had thought of getting a rotary edger to serve this purpose. I have a weedeater, but I thought this would use a lot of line. Would I need something with a bigger blade to take care of this?
Welcome to the forum. I would say the the "least expensive" way would depend on a number of factors including cost of the tool, and cost of your time. Since you already have a weedeater, I would suggest trying it. I use mine all the time to form a (fairly) crisp edge on grass. Turn it so the line runs vertically rather than horizontally. It takes a little practice but one you get the hang it's not hard. Two things to keep in mind - you are only cutting with the very tip of the line so hold the trimmer as high as possible. Second, as the line wears down the machine works hards and there's an audible change in the engine. When you hear this tap your trimmer to get more line. If you don't you're actually making it harder on yourself and the machine as pretty soon the line will heat up and fuse to itself causing you to stop and rewind the line.
