Courtesy of the squirrels, I have several two year old white oak seedlings that I would like to keep but they need protection from browsing deer. They are outgrowing my wire cages in both height and spread so I am looking for other options. I have noticed seedlings often grown in "tree tubes" where the tube is taller than the plant. The plant must have also been trimmed so they fit in the tube and all the growth is directed upwards. I am looking for guidance if a tree tube is a good option. The only thing I found so far was info from the tube manufacturers. Any thoughts on other options would also be appreciated. My concern is not rutting but deer browsing on the new growth.
