Last week I wrote about raised bed gardening and I got an interesting response from Sara.: “Your recent article about raised beds, called to mind a question I've been pondering. In hot, dry climates such as So. California, what about sunken beds? Would they hold water longer so the plants don't dry out? I know in some areas such as AZ, the grass areas are somewhat sunken, then flooded once a week with water. They find that it saves on water usage while keeping the grass moist for about a week. I am referring to vegetable beds, here. What would be the advantages/disadvantages?”
I haven’t really been able to find any information on sunken gardens, other than for aesthetic purposes. Have any of you experimented with this idea or do you know of any resources we could direct Sara to?
