Strawberry Plant help

So a couple of months ago I bought 3 strawberry plants to grow in containers.
I didn't pulled out the blossoms like I should.
Can/should I still do it?
They have 3-5 runners each. 2 of them, when touching the clay soil developed tiny little roots.
How can I use them? They won't take in the clay soil, will they? Or should I cut them and plant them in new pots?

 

They will, wait till they have established themselves before cutting them off the parent plant
