I'm starting to hate tree tubes for so many reasons but the big problems I'm coming up with this year is straightness. 5ft tubes and many of my bur oaks are 6-7ft now. The problem is almost all flopped over at almost 90 degree angles once they came outta tubes and stay that way. I thought the sun would pull them back but it didnt so on the worst ones I ran bamboo rods inside the tubes and tied the top of the tree up but I dunno how long to leave it like that. Second, if you look inside the tubes the trunks of every tree goes from one side of the tube to the other and back over and over, so basically the trunks have multiple S shapes to them inside the tubes. These are gonna be in my lawn will that kinda straighten with time or will the trunk always have funky curves?
