A close up of the hole. The shuttering at the top is 3x3 and the hole extends around 2 foot six down. The ground never freezes in London (we get an inch of snow once a year) so I have concluded that I do not need to go real deep.
Digging the hole was a nigthmare.
I hope I have got this decision right.
