Tree Tubes
I am really looking forward to trying tubes that...
A) Don't come apart...period
B) Animals can't chew on or climb up
C) Don't kink over because of weak side walls
E) Don't require assembly
So far I have used both the blue Protex tubes sold by Forestry Suppliers and the Plantra tubes offered thru NWTF and both fail miserably! Now that is not so day they can never work because they can but they have too many weak points to suit me and I have switched to Miracle vented tubes by Tree Pro and sold for $2.50 ea. (100+) by
Timber Management LLC
Because the Protex has to be assembled it means there are "flaps" and "edges" that seem to attract critters such as coons who love to chew on them.
The teeth marks are unmistakable
Which means I find them like this
Torn apart and trees either exposed or crushed
Note the chewed off oak seedling re-sprouting (thankfully) just outside the edge of the tube
95% of the problems with critters chewing or climbing on tubes takes place when trees are planted in and around heavy cover and only rarely is it a problem in open field areas. There however wind buffets the tubes and tends to open up the Protex and flatten the Plantra tubes. Some of the problems can be overcome by using ties or wire thru the openings on the Protex and using two posts on the Plantra tubes and wiring thru holes in posts to prevent them from being dragged down. So far 100% of Plantra tubes used in multiple locations on several farms have been dragged down...multiple times I might add!
The Protex tubes fare better in open field areas if they are put together properly and a tie or wire used around the entire tube and stake...if they stay together they do their job and trees do very well in them.
You can see the growth of these Dwarf Chinkapin oaks in these tubes...
On a slightly different note...this is a 2 yr old fall planted DCO seedling (planted in fall 2009 as an acorn)
Compared to Rootmaker started seedlings planted in summer 2010
Other problems that need to be addressed with tree tubes and seedlings in general is depredation by rodents of which the worst can be mice, voles, ground squirrels and rabbits. Keeping the area completely void of weeds is one way to solve that problem. No mouse that wants to live long is going to caught in the open, so a 100% weed/grass free area surrounding the tube will eliminate most of those problems. I would add here that the Plantra tubes are soft and easily chewed thru while heavier tubes such as the Protex and Miracle tubes mice are forced to dig under.
3 years ago I ordered a single weed mat just for the sake of experimentation and used herbicide around it to boot. While on this single tree I have not had a problem...you can see that they are an invitation for burrowing rodents to crawl underneath and kill a young tree...
On the other oak trees I used a combo of Oust XP, Prowl and Simazine and keep the area bare and exposed...an inhospitable environment for mice!
the area around each tube is weed free and trees are growing rapidly in the tubes!
Around my fruit trees last year I sprayed Simazine, Prowl and crop oil on growing grasses and weeds and as noted previously if smoked everything without harming the trees. What is interesting however is the ability for this herbicide cocktail to kill via the roots as well as thru the leaf. Note here where heavy rains last spring caused the herbicide to "run" and it killed everything downhill of where I actually sprayed.
Both herbicides used are residual per-emergence herbicides that are not typically expected to kill weeds post emergence but obviously applied heavy enough the combination has powerful post-emergence capabilities.
Frost and Freeze
We had a freeze back in April when temps dropped to 23 degrees...usually not a problem except with 80 degree temps in March everything was leafed out! Young oaks and chestnuts appeared at first to have been killed with all leaves appearing stone cold dead...
but weeks late all have new leaves
and buds
In a recent Oikos Tree Crops news letter they had this to say...
FROST DAMAGE
After this last cold snap it is important to note that frost damaged seedlings will grow again and unlike annuals are often invigorated by the process. The storage of energy in the roots will produce a re-leafing often more vigorous than the first time around. Unless very severe low temperatures are experienced, only the new leaves are burned. The complete vascular system of the plant is not destroyed so the stems will still be green. (You can do a simple scratch test to check this.) Some plants, like oaks will further increase root mass when soil temperatures drop.
A friend of mine back east recently was mortified to find even his 10 year old chestnut trees all appearing dead after a recent hard freeze to 25 degrees but I believe they will recover in the next few weeks and I'm looking forward to hearing back from him.
I took advantage of a late spring sale at
Oikos Tree Crops to buy some potted Ashworth Bur Oak seedlings for a buck a piece along with some Schuttes Oak and ‘Sweet it Is’ bur oaks so when they arrive I'll be tubing them with the Miracle tubes and start testing them with what I hope are....better results! :way:
