Ah - I don't think I phrased my question very well. I wasn't asking about the amount of effort you put in, but more about the amount of weeds.

Yes, weeding for three hours solid is a lot, whatever the weather. But having enough weeds for it to take three hours if I were to get them all out isn't, for my garden, a lot. My laughingly named "vegetable garden" is a tiny fraction of an allotment in size, but I'd expect a good afternoon's weeding just to get that small space clear.

So I was wondering whether going to the allotment and finding there was 3 hours worth of weeds was a lot, because normally you'd only expect half an hours worth of weeds.
