Job done, almost

Rubbish picture but the only one taken today.
I started digging this drain a couple of weeks ago, hit a problem and sat thinking about it since.
I have now dug the trench, piped it, covered it in gravel and replaced the turf along the length of this path. My difficulty is that the wet area that needs draining is in front of the trellis. I have not done anything there, yet. My solution is to dig up the whole area and add more soil to try to lift it a bit.
That's going to be done at a later date.
