Sad leeks, happy fennel, shed replacement

My leeks at the allotment don't look so great, so I've begun harvest en masse, to freeze.  I don't know if it's because it's been dry/warm for longer than they like, or if it's something else entirely.  It could be leek rust, though I'm not sure;  it might just be yellowing leaves.  Normally I have leeks standing all winter with no problems.  Maybe it's the bed itself, as I have a small row of leeks elsewhere that look in better shape (though still not perfect);  I grew broad beans in this bed earlier in the year, and now that I think of it, they were a little disappointing too:  while no obvious sign of pest or disease, not a huge yield off them.

In the bed next to them, which had Charlotte potatoes earlier this year, the fennel are fat and happy.  In fact, I hope they can stand a bit longer, as I'm not sure I can process several dozen all at once.  Last year I tried fermenting some with dill, which was unexciting;  then I added some kimchi paste to it and made it much better.  If they start going to seed, or the slugs move in, I'll have to make another big batch of kimchi (and I need to free up some jars first!). 

In the same large bed as the fennel, my winter radishes, pak choi and Chinese cabbage are looking great;  I've already picked some really big black radishes.  I keep meaning to pick a pak choi but there have been little Savoy cabbages elsewhere to get through first;  however I think I finally picked the last one (I think!).  I was going to make kimchi with those Asian greens too, but still have at least 5 L of kimchi left.  They can go to stir fries and the like instead.

The son and I, with the help/direction of an allotment neighbor, removed our old half-broken-down shed and replaced it with a new one.  Both were once large wooden shipping crates, and to be honest, not super sturdy (made of plywood).  However, we got the old one out and ready for the burn pile, and the new one in its place, secured to some heavy wooden railway sleepers as a foundation.  We covered it all over with a large tarp (also old and somewhat holey, though we doubled it up) to keep in dry before we can carry on finishing it.  It will need a larger piece of wood to make an overhanging roof, a door, and a good coat of waterproof paint.  See the photo in this post for what it looked like (the very small blue shed on the right).

While it's still been mostly dry, it's gotten chillier at last;  the warm weather lasted all of September and half way through October, which is very unusual for here.  I've known us to have a few warm days in October, but not such a prolonged warmth.  But I think that's our lot:  it's getting much darker and feeling like we might want to light our wood stove again soon.
