The flowers are annuals that are planted twice a year. It is all watered with an irrigation system. I pull a few weeds every week or two. The pavers are sealed every two years. I clean the Koi pond filters weekly. I have a lot of Koi fish. I get great enjoyment out of the backyard and it helps my business. We have parties here once or twice a year. the neighbors use it for prom and wedding photographs.
