Beginner's Troubleshooting Guide/Kit for Hardy Herbs

A first-time mint grower is experiencing browning and curling leaves, indicating a need for straightforward, actionable advice on common plant issues. While mint is considered hardy, beginners often struggle with initial care. A product (like a waterproof guide, a simple monitoring tool, or a small kit of common soil amendments) specifically designed for new gardeners growing common, 'tough' herbs like mint, addressing transplant shock, optimal watering, and light conditions, would be valuable. It would help prevent early failures and build confidence.
