Switzerland here: depends what kind of property. A large garden? The owner will likely call the cops on you for trespassing as soon as you show up (and they will come). A meadow some place up in the mountains? The rule is you camp after sunset and decamp at sunrise, but as with every remote place, if nobody sees you... Picking berries the same: it's stealing (Mundraub, yes in CH is still illegal) so in the smaller garden you'll be seen and probably reported but otherwise you'll be luckier.
