"Supposedly" there was a hibiscus bush/tree in that corner, that Cindy had asked George to relocate to a different part of the yard (which she forgot at the time she spoke to police, but then happened to remember during her interview w/Greta) - and the reason for moving the bush / tree was so they could move the big plastic pool storage box (where you store pool rafts and toys, etc.) over into that corner, because Caylee was getting to the age where she could climb up on the storage box, and they didn't want to take a chance on her getting into the pool from the storage box. OR "so Cindy said"..
