Irrigation with well - overloaded with about 650 m²

Forget 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 right back into the cycle into the source…

I would only water the house-adjacent lower third and lay it out as an ornamental lawn, the rest as a meadow with fruit trees or shrubs.

But they need water too.

If you don’t want a perfect golf lawn, usually yes. If it doesn’t rain for a longer time in summer, you can also do some additional watering with the mobile sprinkler. If you water constantly, you also have to mow the lawn constantly ;) It’s a bit different with the vegetable garden, that needs a bit more water. And of course you have to water regularly during the establishment phase. But you can also time the sowing a bit with the weather

If the weather cooperates. Here there hasn’t been any rain for weeks already. And none in sight. But with the lawn sowing I can and don’t want to wait for weeks. I think it also depends on the soil. If you don’t water our Markish sandy soil properly every few days, everything dries out. Even a simple meadow needs water constantly here.

If you choose well and plant wisely, you can get by with very little water and additionally have more biodiversity. So more deep-rooted plants, ground covers that can withstand drought. There is a lot of information on how to plant gardens more sustainably – and at this size, a lawn area is not really that exciting. The [märkische Sand] is, however, an extreme form. Are irrigation systems with well water now prohibited in Brandenburg due to the low groundwater level?

Yes, it doesn't look any better here either. A drizzle of 1-2mm in the last few days but otherwise dry for a month. And as I said, I would also water during the germination phase if the weather doesn’t cooperate. That’s what I have the cistern for and the OP has their well. I just want to push back a little against the idea that you basically have to water the lawn constantly. Some soils require it more, others less. And many not at all. I also agree with , just lawn is relatively boring and at the same time a quite maintenance-intensive thing if it’s supposed to look “perfect.”

Isn’t irrigation with well water banned in Brandenburg now due to the low groundwater level?

No, only sometimes in summer at certain times, for example last year in July/August from 8 a.m. to 8 p.m. I wouldn’t plant just lawn either. But here, the other plants also constantly need water, more or less.
