You'll probably get this as you play the courses but if you need help, play a few holes and save your "aftertouch". When you've saved up enough, hit the ball into the taller grass around the hole and on the next shot, ding it in. As long as you make a decent shot you should have plenty of nudge time to get it in the hole.
I'd avoid going for this out of the sand. It's much easier from the grass.
