A lot depends upon the type of flowers being gardened. If they include annuals, hand weeding is the only real option. If it is exclusively bulbs and perennials, pre-emergence herbicides such as oryzalin (if there are grasses) or isoxaben (if no grasses are present) will clear that “weed bank” after repeated use.

There are few flowers. It’s mainly azalea bushes around the edges with a large empty space in the middle. I’m not quite sure why the last owner left the middle empty.
