this is why I use them. grass is 2 foot high

one year is short one and second year its out of the top be 18 inches

In addition to browse control, they also stop the deer from rubbing on them. Another benefit is the greenhouse effect to amplify growth. I know they add a significant cost to planting but I use them on seedlings that require a high amount of labor to get in the ground…like hardwood rootstock.

I ordered some Plantra 5' tubes the other day

I should have said to get the ones with the hole halfway up, hopefully they are most now days do,

I used them when I planted a lot of sawtooth oaks. I bought a Stihl gas drill with a side handle and a 5-inch auger. It would be a wrist breaker without the side handle. It piles the nice fluffy dirt around the hole, just put the seedling in and push the dirt in over the roots. I also put down a 2x2 piece of black plastic before the tube and stake to keep the grass and weeds from growing around it.

Why do want a hole in them? I would think mice could crawl through, depending on snow depth

the holes are only in the top half of the tubes, an a allows the air to flow thru some, the holes are only 1/2 inch , just found some that I planted 3 years ago, during hunting season, I flag them so went I come back I can find them, well they are only about a foot high, the ones that I planted at the same time with the tubes are 5-6 feet with tubes,

Do you think maybe the tubes help to get the seedling to grow taller to reach light?

I've thought about taking a hot nail & putting some small holes near the top of tree tubes

I used wood stakes the other day for the first time ever with tree tubes. They work decent but then it occurred to me that mice could crawl up them.

I use tree tubes down here all the time, and it definitely helps. Have to carefully watch them though as fire ants have learned to build inside the tubes and mound dirt up the tube which will kill the tree. I hate fire ants.
Not that ya'll have to worry about that up north, just putting it here for any southern guys.

Up here, the forester had told me to lift the tube about 1 week a year to discourage ants.

Ants are like beaver…relentless. Unless you kill them all, they will just build back bigger if you disturb them.

I’ll be planting dogwood whips this spring and thinking about using sections of corrugated sump pump hose as tubes. Cheap and would prevent being browsed all the way to the ground.

In the south, they are a fireant magnet. I have had them girdle the trees. Also had some trees extending out of the tube get damaged by blowing around and rubbing on the top of the tube and breaking off. I dont use them anymore

That would be bad

I plant bare root seedling oaks either with a tree planter behind a tractor, or if not planting many with a dibble bar or spade. Then I drive a 30" x 1/2" rebar beside it and leave a foot sticking out. Slip a 5' PVC over the rebar and attach to the 5' tree tube. Leave it on until the trunk splits the tube.
The pvc is flexible enough to help build girth on the new tree's trunk. It also helps keeping the tree from breaking off above the tube during high winds.
5' tube is necessary here to keep the deer from browsing them off.
I find that if I bury the bottom of the tube slightly with dirt, mice and voles are less of a problem.
I have trees all planted the same day. Those with tubes are 10' tall or so. Those without, are no more than 2' tall due to deer browse.

Rabbits are a key reason for tree tubes.

tubes work great 3x the growth,

Ok, cool.
I suppose it's partly a result of the greenhouse effect. If the summer is dry & excessively hot, I sometimes wonder if such a greenhouse effect could be a hindrance. I'd be curious to hear others thoughts on that.

My long experience with tree tubes is some tree species do great in them and some don’t.
Depends on soil, moisture etc too. I’ve found better success by drilling half inch holes here and there in each tube
