It was necessary as it was the site of an old stone steading that had fallen down 50 years ago so I had to remove a lot of very large stone. In order to raise the soil level back up I have added a couple of feet of soil and compost but it is all very loose and I am concerned that the capillary action in the soil will not be working effectively (the sub soil is heavily compacted blue clay). Does anyone have any ideas about how to help this?
Do you mean the garden is in the foundation of an old homestead? That is so cool!
I would think just establishing healthy root systems from a polyculture of plants will quickly stratify your substrate.
The suggestion about growing root vegetables that will deposit a lot of biomass deep into the soil is a good one. Radishes grow very fast and can be started ASAP.
Other obvious additions, depending on climate and what you want in your garden, would be daikon, comfrey, burdock, nettle, nitrogen fixers like peas, etc.
the soil will work it self out.
If you are worried about water sinking below your soil and running along your clay layer, you could try using buried wood to wick it upwards.
