@bernard As I've said in other threads, I've since discovered we're also in a drought. It's getting worse. It makes sense, in retrospect, because not only did we not have any storms during hurricane season, we had the least amount of rain last year in eight years as far as I can tell. I had almost no weeds in the rock garden. I had to weed it a few times. The previous year, the weeds grew up past my knees and kind bent over. I'm guess this was some type of grass. The plastic under the rock beds is almost as old as time. I won't have to weed again. I'll have moved long before it becomes necessary.
Oahu, on the other hand, is having catastrophic flooding.
