I gather as many as i feel like sinking, this yr its 23. I use 8-10 per spot. I prefer oval shapes so everyone in the boat has brush to fish. I place them in 14-17 ft of water. I trim the limbs and make them look like poodle bushes and then place the bases in pipe or buckets and fill with concrete. My trees work great about 4-5 months after placed. Probably get 20-30 keepers off each pile every time you fish them. heres some pics
