Ok... so for the not so obvious question of the day. I just recently purchase 5 foot solid tubes from Timber Mgmt. Great products and the service was excellent. The tubes have ventilation holes. I assume these are placed closest to the ground to allow air movement from top to bottom??? A few pictures posted here do not look that way. I am planting Chinkapin oak seedlings. Once the tubes are anchored to the bamboo poles are you annually removing the tubes to trim suckers and prune as needed or will that be necessary? Thanks for the help in advance
Here are Timber Management's install tips found on their website:

• Always use a ventilated tree shelter for heights 48'' and greater.
• Always center the seedling's trunk where it comes out of the ground in the middle of the tube
before driving the stake into the ground.
• Ventilation holes allow the interior of the shelter to stay cooler than some other shelters.
Consequently, the seedling will go dormant in the fall and not suffer dieback.
• The shelter protects the seedling from rabbits, deer, and herbicide splash.
• Each shelter needs a support stake.
• Zip ties are already attached to each shelter.
• Stakes should be placed on the North side of the shelter to prevent shading of sunlight.
However, always place the stake on the opposite side of the direction that the seedling is
leaning or it may grow into the zip tie on the inside of the tube.
• The vent holes start about 18'' above the ground.
• Bird netting is provided and is to be placed over the top of the tube. Birds sometimes think the
shelters are posts and enter through the top of the tube.
• Bird netting must be removed prior to the terminal bud growing out of the tube. Failure to
remove the netting will result in a poorly formed tree as the bud will grow at an angle if it makes
contact with the netting.
• Remove the netting prior to the main leader grows out of the tube. This will vary from species to
species as the growth rates are different.
• Recommend using a seedling between 17'' and 24 '' in height.
• Tubes can stay on for 5 to 7 years.
• Remove the tubes before the butt swell of the seedling starts to grow close to the side of the
tube. Moss will grow and create too wet of an environment which retains water, loosens the
tree bark, and once the tube is removed the tree will dieback due to a girdling effect.
• Deer populations and species selection will dictate the height of the shelter used.
• A great book to help with tree identification in Iowa is Forest and Shade Trees of Iowa by Peter
J. VanDerLinden and Donald R. Farrar

* A more specific response to your question on the vents is to keep them at the top of the tube. At the bottom creates windflow issues that basically suck the moisture away from the seedlings.
