Thanks so much for your replies and support... I've been stressed to the max since I worked out the cause this afternoon.

I'm more p*ssed at hubby. Neighbour saw him hand weeding a couple of weeks ago and asked for advice on how to best get rid of the new growth of poinciana that their yard is riddled with (they felled a huge poinciana when they moved in a month ago).
Hubby replied that we always hand weed - but failed to explain the importance of why we don't spray weed killer.

Trident Maple's leaves have turned completely yellow, all the Azalea's leaves are drooping sadly, Ficus has some yellow leaves (but is temperamental at the best of times, so could have escaped it), Serissa is yellowing... Little Ruby, Camellia & Olive are all losing leaves at a rapid rate.
The other kids in our collection appear to be unaffected.

Four days after the event is likely too late

That was my first thought... but I recalled some herbicides are activated by water (i.e. work better if applied just before rain).

Feeling desperate about it... would soaking in a tray of water be better than flushing the soil from above? Bump up the sun... or move into the shade?
