I prefer cedar trees of different sizes. Attach a weight like a cinder block. They last for years.
Dave is absolutely correct.
For the inexpensive route, Christmas time is the key! Once everyone tosses out there old trees...pick up 2-3 and cement them to cinder blocks. I have three in our pond right now and they are loaded with baby bluegill. I toss some food out and the tree that looks empty is suddenly alive!
