Irrigation
Home, or drip irrigation could appear
wasteful, but it is actually less so than conventional
watering. The average oscillating sprinkler loses almost as
much of its moisture to the atmosphere as goes to water the
garden. The droplets it shoots high into the air begin to
evaporate before reaching the plant. Water evaporates from the
foliage before it sinks into the ground, especially in sunny or
windy weather.
Typically, also, a homeowner sets up a
sprinkler and does not come back to turn it off until the
ground is so saturated that water is running into the street.
Additionally, because movable sprinklers are hard to adjust to
the actual shapes of individual growing areas, water is wasted
over patios and walkways.
High pressure sprinkler irrigation, such as
drip irrigation, supplies water in a much more efficient
manner, and is overall more effective.
Is Irrigation Necessary?
If most summers in your area are relatively
rainy, and you water only a few times in the average year, then
one dry summer should not be the deciding factor whether to get
an irrigation system or not.
Of course, even in moist-summer climate, a
few spots such as under roof overhangs, do require constant
attention. If you have such places, consider a system for just
those areas, rather than an all-encompassing one for the entire
yard. A simple soaker hose, easily hidden using bagged bark
mulch in landscaping and turned on manually, will only cost a
few dollars yet will easily take care of an exceptionally dry
bed in an otherwise humid climate.
Otherwise, drip irrigation supplies more
water than many residential lawns need, (becuase they are so
efficient) and may not be needed if you actually enjoy hand
watering and are generally available during the growing
season.
