 It's just, I have put one on one side of my yard, one on the other side, and this one's dead, just like out of nowhere. And I all of a sudden looked around and my neighbor has this big magnolia tree that's almost in my yard. And I noticed it has all these running roots across her yard, which is taking everything out. And I'm thinking that that's sealing the water for my shrubs. So if I replant again, what can I do that that doesn't happen again?
