We planted a Bottle brush tree a few weeks ago. Because of sandy soil, we used black cow fertilizer and topsoil. We try and water every other day. Leaves are getting dry or yellow with black spots. How can we save this tree?

The soil may not be draining well enough. Bootle Brush Trees need a well draining planting site. They are not too fussy about soil conditions, as long as their roots do not sit in soil.
The topsoil may be to dense for the tree, and the fertilizer may have been to rich in nitrogen. This can burn and kill the roots if it was in contact with them in the planting.
Generally you will not need to fertilize until the 2nd spring after planting.
Unfortunately this tree may not survive in it's current situation.
I might dig this tree up and determine the condition of the roots.
If they are blackened and soft, you can trim away these roots to see if there are remaining healthy roots left.
You can remove the soil that was heavily mixed with the manure and replace with new soil.
Then continue the correct watering schedule.
