I will use one cinderblock per 6 Christmas trees and I probably could double that amount of Christmas Trees with no problem. After 6-8 months they are waterlogged and sink on their own. I just use paracord, tied to one trunk, run it through the cinderblock, tie it to the other trunk and repeat.
Tying the cinderblock to the boat and then just untying it when the boat is in the correct place is the easiest thing to do. I just don't want the fabric in the pond, I think it will only last a few years before it starts to degrade.
At the time I put the sandbags in as weight I wasn’t thinking about them degrading. Blocks will be much better in the long run . My biggest problem is getting the trees out in place . Only have a small 12 volt trolling motor and a 10’ boat . Have tried to pull stuff before and it wouldn’t move it so had to string rope across corners of pond and drag it out to position with tractor .Green cedars actually sink as soon as they are in water. It’s a pain to do by yourself…..
