After watching the sun all day yesterday and digging over a bit of the area I was looking at I'm going to have to give that bit a miss, it's shaded till really late in the day and compared to the rest of the area the ground is very damp :(
The other end has much better ground but 2 trees in it and the middle area has bamboo in which I'm very slowly digging out so not a huge amount of room to plant things just yet :(
