I had some yew hedging which died of phytophthera, which thrives in wet land. I was advised to replace the soil. I did, but in the course of so doing, my trench filled within a few inches of the surface (at 9 m above sea level). I think that it was simply run-off, but it did not dry out much even in good weather.
My old garage pit, which was too shallow for me at 5' 7", used to fill up about half a wellington boot's depth, so I think that is a reasonably accurate estimate of the level of the water table. That is probably consistent with the depth of our sokaways.
After a dry autumn, my vegetable patch is pretty dry down to 2': I know because I have been digging out bindweed. ? However, if it were always like that, nothing would grow.
So I conclude that a 2 m earth rod will always have wet feet here, but in fact, most of it will always be moist.
