Hi Angus. Am I right in saying it doesn't look like a huge amount? If so, I would dig them into any borders you have but spread them out a bit, spray them with weedkiller and leave for a little while first. If you pick a dry,calm day and do it at night the weedkiller really isn't an issue. I'd recommend Resolva as it works very quickly. Even just spreading them out and leaving to dry for a few days would probably see off the weeds. The other thing you could try is blasting them with a hose before digging them in but that may be messy so it would depend on what's nearby!
If you don't want to, or can't do that it's a case of bagging them up and taking to the nearest tip which is a bit of a chore.
