 It just doesn't perk as fast as you want it to. There you want to be at soil or even a little bit above, so a kind of slight mound, ever so slight. If you do that, you are going to have a plant that just takes off. Not only that, but your worms are going to take off. You may not see a worm when you start digging that hole, but you will when you get done. Within a month, you're going to have activity going on in that soil. That's what plants like.
