The weather is constantly changing as we are
faced with natural forces of the environment everyday. Your 
landscape
feels the consequences of the weather as well. The orientation of
your has will have a direct effect on your landscape and the light
it will receive. Generally, each side of your house receives a different
amount of light or receives a different amount of wind during a given
year.
The South side of the house receives the most sun
exposure throughout the year. It is in shade in early morning and
late evening during the summer. It is also the warmest area in the
winter. The south wall is protected from 
the
cold winter winds which typically come out of the north. It has the
longest growing season and may be more favorable to plants with a
more southerly hardiness zone. The south side usually has extended
outdoor use in early spring and late autumn.
The East side of the house is the most
moderate of all zones. It receives morning sun exposure, yet benefits
from afternoon shade. The east side is protected from both prevailing
and cold winds. It is a favorable location for both outdoor morning
and afternoon activities. In addition, the east wall is a good 
location
for plant materials that require partial sun and shade.
The North side is typically the coldest, chadiest,
and dampest area throughout the year. The north side is exposed to
cold winter winds. It is a good location for 
outdoor
use during summer months only. It is good for plants that require
shade and may require plants more suitable for northern hardiness
zones.
The South side of the building receives direct afternoon
sun exposure and benefits from the morning shade. It is exposed to
both the prevailing and cold winds throughout the year. Moreover,
it is the hottest and driest location of all during the summer. Shade
is a must in this area during the summer months. This side requires
plants that are both heat and drought tolerant.
