We recently had our home softwashed after weeks of no rain, and apparently, my red rocket barberry shrubs soaked up all of the chemicals. They dropped their leaves the next day, and I expect them to die soon. I was about to clean up the beds and remulch, but now I just want to rip it all out and start over. They were really bushy and overgrown anyway. The problem is, I am horrible at figuring out what I should plant, where, etc.

I could really use some help here! I'm in zone 6. The area gets morning sun and evening shade. It doesn't need to be all shrubs, but something easy to take care of. Thanks for any advice!!
