Drainage advice needed - help :-)

I think I have a drainage issue, but conditions just don't fit anything I can find online or in books.

If anyone can help / advise?

- I have a loam soil, however, this is 1 - 2 feet of loam over rubble (red brick and stones from a previous building on the site).
- I did the "fill a hole with water" test and it drains away easily within 20 mins.
- Over winter I have a lot of moss growing on it.
- I had been walking on it quite a bit while hard landscaping and planting the area, so some compaction I think.
- I have maybe half the area planted up at the moment from last year, each plant planted with compost, loam, grit mix
- site is level.

So, do I really have a drainage problem and if so what to do about it?

digging compost into the unplanted areas? but this doesn't seem to be a long term solution.
Nowhere I look says how to improve soil for drainage when you have plants in the ground or a mature boarder etc?

I had a crazy idea of using an auger to drill down, in several places, to the brick layer then back filling with a grit, compost mix, might that help or just too crazy?

thanks

That doesn't sound like a drainage problem particularly.
Not unless you've got a clay bed under the bricks.
The moss you have there is probably due to the wet winter and perhaps the garden is shaded?
As it's compacted the moss no doubt likes the flat surface. You may just get away with skimming it off, and then digging the loam over to get some air into it.

 

Thanks. Maybe, I dug it's surface a bit yesterday and it seemed like just a hard ish thin surface with moss and looser soil beneath.

For some reason soil related things just confuse me a lot!!
