[CANUFNET] oak planted in tire

Great advice Ron.

Pat, 

If possible I would try to sensitively remove the tire and then leave the
tree alone for a few years and see what it does with no more interventions.
If it survives, then perhaps proceed to Ron's option A advice, then to
option B.

One other thing to consider is whether an English oak can ever realistically
thrive in that location. I have worked with several of the "royal oaks" in
southern Ontario including the Speyside oak in Halton Hills that arrived in
Ontario as acorns in 1937, sent overseas from England with many others taken
from an oak tree in Royal Park in Windsor, distributed throughout the
commonwealth to commemorate the coronation of King George VI and Queen
Elizabeth I.

Working with that tree and others I have observed heavy frost cracking on
the main stems and usually canopy dieback as well (see images attached) from
the Speyside oak. The "polar vortex" winters were very hard on these trees.
I feel that these trees are at their genetic limit to survive in our
climate. If that is correct then a tree in the Bruce Mines area will have an
even harder time than one in southern Ontario.

Something to consider.maybe climate change will help with this.

If you do consider replanting, maybe you could source some acorns from
Scotland or somewhere else as north as possible so that the parent genetics
may already be more hardy.

My 2 centsJ

Hi Pat. For a commemorative tree it sure has been neglected and subjected to
harsh treatment. So sad. 

I'm writing from Vancouver Island where the Garry Oak is the only native oak
in western Canada. We also have some amazing English Oak, many of them
planted commemoratively during Royal Visits. Both species are members of the
White Oak family as you probably know. The English Oak grows fast out here,
probably twice the rate of a Garry Oak. If the Bruce Station tree was out
this way I would suggest trying to improve the cultural conditions around it
immediately by removing competitive plants, ie grasses and mulch to optimize
the tree's ability to produce absorbing roots while you are frost free
(almost all winter long here on the coast) and then in the spring at the
first sign of new growth do one of two things: a) Cut every bit of dead off
back to live wood no matter how drastic you have to be or; b) as I would do
here to an English or Garry Oak tree in that condition, cut it down entirely
at first sign of spring growth and hope there is enough energy in the
juvenile wood at the base to push up some basal suckers that can then be
selected out to the strongest stem and allow you to grow a new tree. The new
basal sucker tree would outgrow the tree that exists currently. Perhaps out
your way you might consider doing the above suggestions in stages. Improve
rootzone, prune heavy, watch it over the growing season and if it shows
improvement, cut it down the following spring.

HI All 

This is an oak planted between 50 and 70 years ago in a tire. It has also
had some damage from lawn care. 

The Bruce Station Horticultural Society is looking for suggestions on saving
this tree as it was planted in memory of their first President. Their goal
is to plant a commemorative garden for all the past Presidents in the area.
Money is short and skilled labour a challenge in this region. 

What do you suggest?

What are priorities?
