I have a drainage issue, water not draining through the ground. What I have done is drove a steel bar down 20 inches into the ground and filled up with drainage stones(about 12-14 in). I filled up with water and only drained 1 inch in 4 hours. My intention was to have these holes about 18in apart throughout the whole garden. But not sure this is going to work.The garden is 85 sq mtrs. Do you have any suggestions.
