Do you ever wonder how we determine how often, or for how long, we water the common areas? Well, there are several factors we consider when we are adjusting the sprinkler clocks. First, there is the weather to consider. Obviously, if it is raining we shut everything off and leave it off as long as possible. As the rains subside and the warmer weather sets in, we will begin to slowly turn the irrigation back on. At first, we will water one or two days per week and then when summer is in full swing, we will water as needed in order to remain within restrictions set forth by your city codes.
Next we need to consider the type of plant materials we are watering. For example, we have mature trees in all the turf areas. If the trees were all by themselves with no grass around them, we could water them as little as a few times per month! Trees generally have large root systems and by nature they will seek moisture deep in the earth on their own. However, the trees planted in the turf areas are subject to the water necessary to sustain shallow rooted turf grasses. As a result, the trees do not need to work hard for their water and their roots are bit “lazy”. That is why you can see so many roots close to the surface in many areas.
Then we have the planter beds. In these areas, we target the water cycles necessary for the standard plantings. In most cases, these plants are mature and do not require as much water as many of the flowers planted by homeowners. As a result, the homeowners who plant flowers may need to supplement the irrigation with a little water from their garden hose in order to maintain their flowers.
