Hi Tina,
Before you pull them up, just wait until Lin gets in tonight so that she can double check my IDs.
Getting rid of soil is a real pain, isn't it. I have many, many window boxes and tubs and it is such a pain to get rid of the old compost in them when I'm planting new stuff. I've just finished 15 tubs and window boxes and about another ten large tubs that I grow veg in. They are all for me, sadly, none for Doris and Dolly, as there is enough stuff growing in my herbaceous borders for them, plus lots of lovely weeds growing out of cracks between paving stones in my front garden.
Re the weeds in Jonny's bed. It could well be that these new not-so-nice weeds have arrived from seeds that have just blown in on the wind or have been deposited by birds. It's amazing how clever weeds are about insinuating themselves into every nook and cranny. There is an absolutely wonderful book by Richard Mabey called "Weeds: The Story of Outlaw Plants". Here's a review of it:

Anyway, I wouldn't be surprised if you are finding stuff that you didn't plant in your weed bed, given the nature of weeds!
