So scrape it off again. Really! If I thought these things through properly first I could save a lot of work.
Cut back the old wood on the thornless blackberry. The remaining berries were small and not worth picking.
Took out the sweetcorn stalks and tried to rake the soil into what the books call "a fine tilth". Some hope! I have a smart new rake which is very pretty, but no use at all on big lumps of clay soil, it just bounces off. So I had to get the old heavy duty one out and bash away at it. Did the job though!
The next thing to come out is the runner bean frame. There are still a few left and I've had precious little this year so I'm getting every last one.
