Where the
wild things
are made
A spring
phenomenon
The power
of boosting leaves
That occurs
only under limited
circumstances
at certain times
of the year
Beyond the surface,
there is a miracle
of root pressure
Root pressure occurs
in early
springtime
when the soil begins to warm.
As the weather and soil conditions
become favorable.
The roots
absorb water
and minerals
from the soil and accumulate
minerals in its sap
AT HIGH CONCENTRATIONS
by osmosis.
A tree with a pressurized
root system
STARTS FLOWING SAP UPWARD
through its xylem system
to prepare
boosting leaves.
These pressures in trees are not nearly enough to transport water
to the top of the tallest trees.
There is also an
auxiliary force generated by evaporation
and transpiration
of water by the sun, which
creates the additional pulling effect
towards the tree top.
All contribute to the rise of sap in Birch trees.
