I went to visit a customer last night regarding a problem with a new bed we installed. The site of the bed is the location of an old 48" oak tree that fell in a storm (on the house none the less). Most of the stump was pulled from the ground and was hauled out by the tree contractor. The remaining root flare and stump were ground out by the tree company - they did a pretty good job. At best this was about 10" below grade. The tree sat next to the driveway on the higher side of the lawn. Once the stump was ground out we hand dug the stump grindings out and hauled them off site (about 3 to 4 cubic yards). We dug down to solid soil. We added about 3 yards of top soil to fill the hole in last fall before the winter. This spring we rototilled in 3 or so yards of leaf humus into the top soil as she wanted a perennial bed. The completed depth of the bed was about 8" thick (lots of air!). The bed is about 400 to 500 square feet in size I'm guessing - 16 x 25 ish. The low side of the bed is next to the low point in the lawn which now collects water in the absence of the huge oak that is no longer pulling water. As well, she's watering now more than she did before since she has perennials in full sun that she never had before. Now after time the bed has settled a bit. I dug a profile and found about 6" of nice bed material (may have a bit too much organic matter - have not tested volume yet) and under the organic matter is blue clay - with the wonderful odor of anarobic decomposition. Ummmmm good. I think I have a perched water table... drainage is poor, plants are dying and I have a wet bed due to both poor slope/grade and over watering. I need to correct the soil/bed. We're considering drainage for the rest of the back yard and I was thinking of running a couple of veins through the bed just to be safe. Then we would redo the perennial bed and re plant. But how do I change the soil profile? I remember from a class oh way back when we asked the prof the same question and he said - Mother Nature and time. I have control of niether. Any thoughts on my problem would be appreciated. Thanks.
