I've had one in the backyard for over 10 years now. Once it got through the first year it's been the easiest most carefree shrub I've ever had. Rarely had to water it past the first couple years. One good soak at the end of winter if it's been dry. One year we had stiff winds that blew it down and broke it in half. It came back.
Here's my question: This year it's looking kinda scraggly. It has trunks as thick as my arm. Should I chop it down and see if it comes back?
