How often do I need to water mint? I'm planting them because apparently they are good rat deterrent and is necessary for mojito lol

They are currently in a pot on my breakfast table..bought it from the supermarket so didn't want to shock it and put it outside straight..I noticed some leaves have withered black spots while others are large and green.

I also have some cuttings submerged in water for it to root so that I can pot them along my sliding door. But my issue is that I'm not sure how much space to give the cuttings in a planter box. Also because the sliding door facing the garden gets a lot of sunlight and it may do very well or just die and the other sliding door is shaded...

Can you show me your mint plant so that i can see how sparse or tight they are in the pot?

I transfer my mint outside...direct sunlight...growing well. But then, needs water everyday..if i forgot to water, the leaves wither immediately. After watering and an hour later...nice leaves again. You are right..mint are resilient.

I just transfer them from the pot to a planter box. growing well now. Will take picture when I remember.

to also note that mine are spearmint, those darker green ones. There are also peppermint which has thicker, furrier light green leaves..don't like those.
