Mint is not picky, but it hates sitting in water. Use a pot with drainage holes. Terracotta is great because it wicks away extra moisture, like a natural air conditioner for roots.
For soil, use a standard potting mix. Add a little perlite or sand for drainage if you’re feeling fancy. Think of it as giving your mint a comfy bed with a good mattress—not too hard, not too soft.
And here’s a fun comparison: mint in a pot is like a puppy in an apartment. It needs room to roam, but not a whole farm. A pot that’s 6-8 inches wide is perfect to start.
