Fennel Seeds

Our fennel is pretty much on its last legs. The five foot stems are now collapsed on the ground and looking a bit sorry for themselves. I need to find out if we should cut it back or just leave it to die back. Any ideas?
The Little Misses were back at school today which was nice for everyone I think!!
After I dropped them off I had to go to the dentists to have a filling replaced. She couldn't get the drill to work properly so I had to laugh as she spent about five minutes turning it on and off right by my ear. I said to her that it was a good job I don't have a drill phobia!!
So with a numb mouth I went to my weekly humiliation at zumba. My numb mouth made drinking water fairly difficult - I must have looked like a lunatic holding my mouth closed as I drank!
And then I spent the afternoon tidying and cleaning the living room. Properly! Cushions off the sofas, furniture all moved to the middle of the room, insides of cupboards. It all looks so sparkly and tidy. It's like we've just moved in!!
I picked up the Little Misses who both seem to have had good days. And it was an uneventful evening with only a bit of silliness from Miss E.
Phew. A good day!!!
