@ai6yr They probably expect you to kill 1/3 or more of the plants. That may well be realistic for people who don't install automatic irrigation.
I know people who spend an hour every evening hose watering their garden. Then they go on holiday and come back to dead plants. Big surprise! 🤦🏼♀️
When I tell them that they should install irrigation, they act like I'm inviting them to my Satanist church. 😂 Year, after year...
