cedars

I'm going to sink some cedar trees this weekend. Does it take alot of weight to sink a 8ft. cedar tree? Do they stand up when sank if you put weight on the bottom or do i need to put something that floats on the top to stand them upright? I've been sinking pvc condos and use 30 lbs on concrete.
Thanks in advance

i would set the bottom in 50-60 lbs of quicret just to be sure

It will take more weight than one thinks to sink a 8' tree, As fish-wva said 50-60 # will sink it,If you use concrete blocks it will take at least two of them.
If you go with the blocks I would put a float at the top to make it stand.
