Now it is really summer. In our region (the Province of Flevoland, also known as “the New Land” (Dutch: Nieuwland, see House and garden ) it is hot, hot, hot, over 30 °C (86 F). Interestingly every week we have had at least one local heavy shower so far. Now the time has come to use our advanced irrigation- or sprinkler-system that is part of one of the three primary infrastructure facilities.
With the sprinkler-system we cover about 2/3 of the grown surface. The other 1/3, part of the front garden, whole of the left side garden and part of the main garden (veranda side) is sprayed by hand. For this we have water-taps connected to the garden-pump, that takes its water from the waterway at the back of our garden, scattered throughout the garden. So we never need to use tap-water for irrigation purposes.
This was only the second time this year that we needed to switch the pump on. We had a relatively cool and dry April and May and hence needed to sprinkle early May. Before we can use the system after the winter period, we first install the pump and then clean the filters, inlet and and all sprinkler outlets.
And depending the conditions we need to do a little more, like removing the groundcover from the sprinkler, etc (see Preventive maintenance and repair).
As the photo’s show the Sun is very low on the horizon. Sprinkling should not be done during daytime but in the evening. The two most important reasons for doing so is the risk of leaf-burn when sprayed during sunshine. The other reason is that a minimum of water will evaporate and get a better change to penetrate the soil.
We frequently check our rain gauge to make sure that we water timely but also not to much. When we use the sprinkler-system we let it run for one or two hours to soak deeply in the root zone.
