As the weather gets warmer, the days get longer and the temperature rises,
it becomes evident that summer is almost here Measures should be taken
in order to accommodate the changing needs of a landscaped environment.
Focus is placed on the importance of a well functioning irrigation system
and it's effects on the aesthetic value of a property. Normally during
the winter months, controllers are off. This year the rainfall levels
have not been what they normally have been in the past. During most of
this past winter, irrigation systems that are normally off, have been
working over-time due to absence of rain.
Irrigation evaluations are most definitely needed and should be performed
as necessary. An experienced technician should evaluate the property paying
special attention to surface plant material as well as color. These tend
to be the first to show signs of stress due to lack of water or any dramatic
changes in the system. Turf will show signs of stress on an average of
about four to five days without adequate irrigation, depending on the
type of turf.
With consideration to climatic changes, normally irrigation controllers
can be set at one cycle per day, four to five days per week for turf areas
with the number of cycles per minute varying according to the landscape.
Special areas with runoff will require multiple start times in order to
alleviate this particular condition.
Here is a small checklist of items to take into consideration when performing
an irrigation evaluation:
-Broken nozzles
-Clogged nozzles
-Valve problems
-Coverage problems
An often overlooked contributing factor to the decline in plant material
on a project is the lack of uniformity throughout the irrigation parts
on a property Manufacturers vary in their specifications and production,
therefore allowing for variations when dealing with even the same type
or category of part. It is highly recommended that when replacing or adding
parts to the system, that using one manufacturer be the ideal.
Keeping these concepts in mind, will most certainly provide a near fool
proof method of obtaining maximum results from your property's irrigation
system. This will in turn benefit the existing plant material improving
the overall appearance of your investment.
