>>852458...Same with a hibiscus that's about 1m away. Already last year one near that spot died, this year another smaller one yellowed and dropped the leaves in early August (normally happens in November to all the 10 other of them spread around the garden which are fine)
Then there's also a privet hedge there with slight damage.
All other things growing in a 2m radius from that spot are unaffected though (lawn, physalis, mint, lilies, Japanese spindle, ivy, bryony...)
Any ideas what could be the culprit here? Thought about shrooms or viruses first, but why would it affect 2(-3) such distant species only?
