I’m debating if I should use the 6 ft tree tubes next year for when I plant more trees? How many of you use them? I’ve never used them in the past, but always had good protection and success between the window screen, weed mats, stone and 5 ft welded wire fencing. Some who have used them say the growth is much better vs no tube. It appears as though they remove them permanently after two years. Is this right? Is it worth spending the extra $? I don’t mind spending the $ if the protection and growth is much better. Any feedback would be great. Thx
