but I was under the impression that acacias are especially addapted for soils low in Nitrogen due to the symbiosis with Rhizobium nodules associated with their roots which fix atmospheric nitrogen, and hence fertilizing can easily have negative effects.

if the tips get yellow for example, it's unlikely to be a N problem, because N deficancy starts with the older phyllodes!!!!
i have seen this aswell, even with plants planted out.
repot or plant out.

When they get rootbound the new growth slows and gets more compact and the tree can't take up nutrients or water properly.
edit: I've seen ants move into a pot, making the soil repellent and causing similar problems with Acacias.

The greatness of a man is not in how much wealth he acquires, but in his integrity and his ability to affect those around him positively.

It sings because it has a song.

Yep, i agree. I think the go is to carefully remove a small amount of soil from around the root system of an established acacia (any, I used a big old A. iteaphylla), and add that to
Thats true, but in pots they may not develop the nodules properly because the bacteria that form them often isnt present in the soil or on the seeds.
your potting mix.
