Hi,
I am dealing with a drainage issue in my garden so I tried using sunken containers with 3/4" gravel and eventually river rocks around the containers. I have a 12 ft x 12 ft patio and all the water from underneath trickles into my L shaped garden. I managed to place the containers on top of this water level but when it rains the water goes to let's say mid container height. My containers have drainage holes maybe 6x 1/2 inch. I believe my inly solution seems to be a perforated pipe to send the water elsewhere or if not select plants that can have the container bottom half submerged in water. Please see my photos and provide any advice! Thanks in advance!
