Any ideas as to what this tree is would be much appreciated.

I salvaged it a year ago, stuck in someone’s backyard, looking very unwell. The owners were unable to tell me what sort of Bonsaiit was. I think it could be a European Ash, but each delicate branch stems out to smaller stems that contain approximately 6 leaves each, which doesn’t really reflect an Ash. Its branches drop downwards, the outer of each leaf is smooth (no ridges), and it has a opposite leaf arrangement. I’ve had it for one year and it has kept all its leaves, occasionally shedding dead growth.

It is growing ferociously and has doubled its size in almost a year. I’m concerned how big it will grow and am at a quandary, as recently the tips of its leaves have started to brown then blacken. It also had a little mold on it's stems and black spots on a few leaves. I have since repotted her in a larger pot with good quality bonsai potting mix and plant food, and also sprayed with Yates Rose Gun (black spot & insect killer).

I don’t know whether it likes full sun, no wind, a good flush of water, fertilizer etc??? Really need to know what this tree is so I can care for her better.

I've attached 4 pics of the leaf formation, blackening of leaves on tips, her trunk and a full picture of her height.

Please help!
