Descriptions of plants include
implicit instructions on whether
to plant them in sun or shade.
Specification as to the amount
of irrigation required is also stated.
Elaborate irrigation systems are sometimes
installed or a trench for
improving the water flow is used.
Controls are needed on
irrigation systems because if
the ground becomes too saturated
the soil in the garden
will be too muddy to
allow anyone to work in it
until it dries out.
If there is too much
water constantly, the garden
will become a swamp
and impossible to cultivate.
Geographic location is important for plants.
Certain plants are only suitable
for propagation close to the equator.
Others need to be several degrees
of latitude away from the equator.
Longitude is also a factor
and most companies clearly state
the conditions that will
provide the optimum chances
for the plants survival.
