Plant Growth spell clarification

Given you can hold concentration in the middle of combat, often even after being struck, I don’t think the mental focus element is that out there. And there’s people who get serious about meditation who can hold a pose for way longer.

So are you suggesting someone casting a ritual spell should have to roll for concentration?

RAW, anytime you cast a spell for longer than one action it uses your Concentration slot.

Concentration is just poorly named.  They could have called it anything.  The only relevant things are (1) you only have one 'slot' for doing it, and (2) if you take damage, you need to make a check to keep the thing in the slot, (3) if anything ends it, you lose whatever you were using the slot for.

So you can concentrate through a short rest.  You can concentrate while solving a math puzzle or playing chess.  It doesn't interfere at all with your ability to 'concentrate' on something in the natural language sense (like deciphering a code).  Only things which explicitly use your concentration slot are exclusive with each other.
