Beginner Gardening: How do raised beds stay in place without a border, 1 by NYGrower

Well you may have hit the nail on the head here. The method you describe was / is used to keep water out of a house basement, and is used to raise the ground around a house to help to that end.

I have seen it, that a new home site is even filled with rock sometimes 1 to 2 feet all around a house, dirt is brought in and then sod is put down. Since it is a new house people do not expect to see mature plants and never think to "dig" or to ask what is in the ground.

If one has a raised septic system in the back or side of the house, one can assume there is a high water table. It certainly sounds like that is your situation. Frankly removing the dirt, may put in a position where you will have water in areas that you do not want. On the other hand it may just be that the folks that built your house found that is was cheaper to do this type of fill rather then to give you good top soil.

The method I gave you works fine for small beds and for terraced beds. For a terraced bed just make one section large say 10 x 10 and then the next 6 x 6.. putting the smaller one on top. You will get a different look, and be able to have some plants hang over the edge. Run a water line in the middle and sink the hose in the ground, put a sprinkler head on the top or a fancy water thing, make sure you can turn the water on and offf close by but away from the sprinkle when the water is on, and you will have a thing of beauty to look at.

You can also do this with the borderless mounds but usually the area should be bigger, and as you said the ground is clay, if you can manage to use this type of medium, you could almost make a mini pool, with garden inside instead of pool water.

Gosh I wish you my best, as I know what a hard time you are having. I would send you roses if I could so I will do the next best thing.... Enjoy my peony.
