Then soak the fuck out of them in copious amounts of fresh water two or three times, cross your fingers and toes and pray to the holy vine spirit for forgiveness.

 

I'd say it' will still be too late for most of them even you do get all the prilled chemicals off them and leach out the excess salts.

 

Acacias don't need to be fed heavily like most plants because they fix their own nitrogen from the atmosphere through bacteria that colonises their roots. A bit of fertiliser is OK but more is not better.

 

It's a fairly common problem though, they look great in cool weather when well fed but when the weather warms up and the plants' metabolism ramps up they uptake more nutrients and fry themselves.
