Tomatoes - when to pot on

[annie8]

Is there an easy rule of thumb about when to move tomatoes to a bigger pot. I moved my tomatoes from modules to individual pots not long ago. Maybe 3 weeks but they are really growing quickly and am wondering if I need to think about putting on again.

When the roots come through the bottom of the pot or it falls over!

They look good, I’d be thinking about potting on in the next few days.

They're going well, I'd put them on, sinking down to the first leaves in a deeper pot

Aye, through the bottom of the pot works for me.

No roots yet but they are looking almost ready. Will maybe give it until next week. It’s san Marzano and Shirley. Growing well so far. My gardeners delight and red cherry are a bit behind this year.
