This is something I did not dig out last summer in case it was useful. Plus it was a bit big and I had limited oomph.
It will be some time before I get to this corner of the plot (at current rate) so it can stay for now.

Expended some more oomph late this afternoon turning over some more earth and getting the couch grass out - next bed needs to go down soon.
In other allotment news, some radish seedlings have appeared.

In domestic goddess news, I baked sweet potato brownies (from Deliciously Ella's blog). They were quite nice and I felt virtuous eating them. Can't help feeling they need the addition of some proper chocolate or some cream. 
Dissertation calls..... after dinner and before a bath.
