Prater4586. I used to place attractors in Santee lake. I used the discarded 'tomato' stakes that were hardwood. I put 2-3 nails at one end of about 10 stakes, leaving the nail stick out about an inch. Found some of the small black plastic potting pots. Got some quick setting concrete, mixed it up, poured it in the black pot, (don't need a lot) and put about 6-10 of the stakes In the pot (with the nails sticking out) and 1 of the stakes in the center with a ring eye at the top. I let the concrete set and loaded about 15 of these on the pontoon to set out. I ran a rope through the eye I had on each pot. Lowered to the bottom and pulled the rope back through the ring eye. Now, you may be able to do something similar with your trees. Drive several nails in the base of the tree, mix some concrete (again you don't need a lot per tree and put the tree in a discarded black plant pot and let it set. You can then just dump the tree where you want and not worry about tying some weight to the bottom. If you want it stand up, you will need to attach a plastic bottle or some other floatation material to the top to make sure it stays upwright when you drop it. This may or may not be legal.
