Answer 1

Yellowing is typically the result of over or under watering. It also can signal a need for nutrients or pest problems. (Potted mints should be fertilized once in the spring with a timed release product.) Check the undersides of leaves for aphids. If you see webbing or mottled foliage, it could have spider mites. Go ahead and prune off yellowed foliage. These articles should help you pinpoint the source:
