I employ a highly absorbant non-reflective medium on the ground plane, ie., a four inch lawn. It's a good excuse not to mow too often.That is a good question, though. Take the ground bounce null frequency out of the loop. With woofers take the measurement with the mic a couple of inches above the ground, the path differential between the direct and reflected waves will be too short to show up in the passband. With mids and tweeters lift the box and mic high enough off the ground to render the reflected wave moot. With a full ranger measure both ways, then combine the low frequency response with the former method with the high frequency response of the latter.
Option two is to dig a hole in the ground, put the speaker in facing up, backfill to get a true 1/2 space mounting and suspend the mic via a boom. A bit more trouble than it's worth.
