Weed Id and dahlia feed

in Plants
Got a rare day off to work on garden. About to tackle an area that has been left bare to weeds. This pretty blue fella has appeared. What is it?

Also, my dahlias in pots are very leafy but no flowers as yet. Should I feed (intended to use tomato feed) or wait until in flower?

That's Centaurea montana. A bit invasive and deep rooted but pretty
I don't know anything about dahlias, sorry
In the sticks near Peterborough
Cheers Nut. just looked him up. Think I might keep him but be on standby incase gets a bit too keen!
Re: Dahlias. It is still early for them to be flowering, but it is time to start feeding them with a high potash feed [tomato feed would be fine ]
When you don't even know who's in the team
S.Yorkshire/Derbyshire border
thanks punkdoc. One of the dahlias has two buds so looking forward to the start of a display in coming weeks
Will start feeding.
Centaura montana is a magnet for bees - worth having unless it likes your soil too much
Actually found a bee stuck in a spider web right next to the centaurea Montana. Managed to free him.
My Dahlias are all in full flower now Im in Surrey.
Some of mine are out, but only the ones I grew from seeds last year,
