Let's get down to some serious business! Shall we try to replace the husband?

I've seen these at Calloways and always thought they were very pretty - I just didn't have a place to put one or I probably would have bought. I'd go with them over ligustrum - I've never seen the curly leaf ligustrum, and it may be a great plant, but I'm just not a fan of ligustrums in general.

dig a few 3 to 6 inch holes around the area under the trunk ... out a few feet ... AND FIND OUT about soil moisture at root depth ... and then water accordingly... or report back and we can opine ... whats the weather been since winter??? here in my MI ... we have been in drought for about 4 weeks ... my lilacs are drooping ... which is my key go to for noting such ... ... if i cared.. i would water deeply ... probably once ... and then see how fall develops ... after 2 years ... your tree should be fully established.. and not really be needing watering on a schedule from you .. but a good drink once in a while wouldnt hurt ... i dont know how water moves thru your soil .... . so its hard to tell you how to get water down into it ... if its drains properly ... i dont see how you could over water it ... if we decide to water ..... i would broadcast it under a tree with a common lawn sprinkler ... the feeder roots.. arent in that small area where you planted it 2 years ago ... so we would need to water a large area .. ken ps: is it under a large mulberry.. if you have a water problem.. that might be part of it ... leaf in last pic

Yes. Brasiliensis. For future reference Dalea have alternate pinnate foliage, not opposite entire.
