Irrigation with well - overloaded with about 650 m²

Forget about the square sprinklers quickly.
Either plan and do it properly (Rainbird, Hunter…) or better leave it altogether. If you have a well, I would definitely install an irrigation system. Excess water goes directly back into the cycle to the source…

The professional brands like Hunter or Rainbird are neck and neck and also combine well. Please just don't use Gardena. It's not good quality for irrigation and after 1-2 years you will have to replace it. It's more expensive too...
Please read properly about how irrigation should be planned.

Thanks, I know - unfortunately.
This is a special topic with many possibilities.
I simply lacked the time for this so far, and since I am already starting the next new construction project this late summer (as soon as the development is finished), I unfortunately won’t have time for it for the next 2 years either.

I currently use Geka couplings and sector sprinklers. They branch off individually from the main line 1.5" PE pipe via T-pieces.
4 pieces in the corners, and about 80m of these drip hoses for irrigation in the front yard and in the beds.

I basically turn the ball valve on, the pump starts, and 2 hours later I turn the valve off again, the pump stops. Done.

It can be done better, but for such a fully automated system for garden, side area and front yard you probably need at least a week until everything runs, if that’s even enough! (as a non-expert)

Landscape gardeners will probably be tearing their hair out, but for me that’s enough for now :D

We have some systems in operation. Blow them out in autumn and start them up in spring or check if all settings are still correct. Depending on the plants, manual watering is not possible at all or employees would have to be hired for it. Less water is needed because the amounts of rainfall are precisely known.
