New Perennial Flower Garden Not Draining
Stupidly, I just planted my first perennial flower garden at 8000 ft. in the Rocky Mountains without testing the soil. Then I decided to test the drainage and dug a 8"x8" hole and filled it with water. It took 5 hours to completely drain. Oops! The soil is full of shale rock and I put a healthy portion of Miracle Grow Vegetable and Flower soil in each hole. I am here each year only from June through Labor Day. What do you suggest that I do now regarding getting better drainage without having to start over?
