Well ... loads of bad weather, seems like summer is alomost non-stop rain around here. The soil is really clay, and soaks up the water. So, it's really heavy going.
Also, there seems to be a local infestation of flies - awful, really awful. A local says he has not known it like this for 40 years. So we have not spent much time at the allotment - running up, strimming and keeping a lid on the chaos as much as possible - whilst burning citronella lamps to fend off the flies.
Today, finally, we saw some result - the first potatoes, and the soil was turnable, so the potatoes have done their job. Onwards and upwards for next year.
