Those with experience planting hybrid poplar and 3' weed mat. If you are in an area of high density, have you had to protect your cuttings year one? I'm a little worried the deer will either nip the cutting off or eat every leaf as it pops and kill them. If I do have to protect them, I'd like to use maybe 4' tubes (hopefully they can get up past the deer once they get to 4') but I want removeable ones since they should only need one year. What kind of removeable/re-useable tubes do you like?
