Fish them around grass, or any type of structure. Cast them out and let them settle to the bottom. Bounce or drag the worm across the bottom by lifting your rod tip, not by reeling. When rod tip gets to about 10:00 or 11:00 O'clock, then lower your rod tip and reel in the slack. Repeat until you get a bite/bump. Real in your slack and point the rod tip to the direction of the fish/bump and set the hook. There are many,many different techniques to using the worm but IMO that is the most basic. I use a 3/0-4/0 Tru-Turn hook on a 7.5 inch worm. I commonly use a 1/8 ounce worm weight but sometimes go lighter or heavier. Try and use as light of a weight as possible.
