Daikon
Unbelievably, we are into our second cycle of growing vegetables. Already, things are looking very different this year.
I sowed some daikon (Japanese radish) during the winter and kept them under a plastic tunnel through the cold weather. Now they are looking very healthy, and we expect to be eating some in a month or so. Here they are:

We are also well ahead with onions and beetroot, also some lettuce and a few other salad vegetables. Tomatoes are in, peas also. Broad beans have been looking great since they were sown in November. We also have a reasonable selection of herbs in various locations.
Of course, this great head start might have more to do with the weather -- lots of rain so far this year -- than any increased expertise on our part.
