I'm still very new to bonsai and trees in general, so I was hoping to tap into the wealth of knowledge you guys hold on this forum. I am currently renting and have a few interesting trees in the yard, some of which come over from the neighbours. I was hoping to know what species these are as I have taken cuttings of some and should probably try and learn about the trees I'm growing.
Tree 1 - maybe a ficus? It's quite a dense bush over the fence, reminds me of a mangrove.


Tree 2 - tall skinny tree, isn't looking too healthy. Can't get good photos of it as it gets lost in the bush around it (tree 3)


Tree 3 - big bush covered in the white flowers, has almost acorn looking nobs.



Tree 4 - reminds me of a melaleuca...


Thanks to anyone willing to help!
