学习有关在院子里种树的正确方法及基础知识。
A
So
this
is
the
spot
we've
selected
to
plant
your
tree,
there's
no
underground
utilities
here,
there's
no
above
ground
utilities
and
it's
far
away
from
the
property
line
that
the
tree
is
not
going
to
overhang
on
the
neighbor's
yard,
even
when
it's
mature.
It's
also
far
enough
away
from
the
building
that
it
won't
be
a
threat
in
terms
of
falling
limbs
in
terms
of
gutters,
or
anything
like
that.
A
A
Now
that
we've
unpotted
the
rip
ball,
we
want
to
look
for
the
trunk
flare,
so
it's
a
little
bit
trumpet
or
cone
shaped
it's
right
about
here.
The
reason
that
finding
this
is
really
important
is
that
this
is
one
of
the
major
places
that
trees
do
gas
exchange,
inhaling
carbon
dioxide
and
exhaling
oxygen,
and
we
need
this
to
be
above
the
soil
so
that
your
tree
will
be
able
to
grow
strong
and
healthy.
We
want
to
look
for
the
first
major
chunky
root,
which
I'd
say:
is
this
one?
A
A
Once
we've
dug
our
hole,
we
want
to
test
it.
We
want
to
make
sure
that
when
we
put
the
tree
in
it
that
the
rip
flare
is
above,
ground
level
looks
about
right.
So
now
we're
ready
to
plant
our
tree.
Now
that
we've
tested
the
depth
of
our
hole,
you
can
always
add
the
soil
back
in
or
you
can
take
more
out
if
you
need
to
so
now.
We
actually
are
going
to
put
the
soil
back
in
our
hole,
and
I
want
to
talk
a
little
bit
about
not
putting
in
soil
amendments
into
your
hole.
A
A
If
you
put
amendments
in
the
hole
with
the
tree,
it
can
cause
several
problems
now
that
I've
basically
filled
in
the
hole
I'm
making
a
little
raised
area
with
upside
down
sod.
That's
going
to
help
keep
your
mulch
in,
don't
forget
to
leave
an
area
about
two
or
three
inches
away
from
the
trunkier
tree.
So
you
don't
cover
your
root
flare,
no
mulch
volcanoes,
please
and
then
we're
going
to
water
our
tree.
A
It's
really
important
for
your
tree
to
have
that
nice
winter
rainy
season
get
established
to
its
new
home
so
that
it
can
be
ready
to
thrive
come
spring
and
summer.
As
far
as
staking
goes
most
trees,
don't
need
staking.
The
only
reason
you
would
really
stake.
A
tree
is
if
it's
still
falling
over
after
you
fill
in
the
hole.
If
you
stake
it,
when
it
doesn't
need
staking
or
you
stake
it
improperly,
that
could
lead
to
weak
wood
in
the
long
term,
which
could
compromise
the
strength
of
your
tree
once
it's
older,
so
to
review.
