To say native arbutus are 'messy' is a huge understatement. As I wrote last Wednesday (see above), they are "an ongoing maintenance nightmare". Beautiful in wild places, large Arbutus menziesii in suburban gardens are a make-work project for sure. You can't not pick up leaves on walkways . . . wherever 2 or more lie one on top of another, it is literally like stepping on pieces of plastic lying on ice - no comparison to the slipperiness of any other leaves.
