Add water to the glass as necessary. Make sure that you change the water every four to five days to prevent rot.

You should add a water-retaining polymer to the potting soil so that it stays moist and doesn’t dry up. You can also use pearlite or vermiculite instead of a polymer. [3] X Research source

You can also plant mint in its own raised bed container, on a bare spot in your garden that you would like to fill in, or section off part of your garden with bricks or timbers to create a barrier for the mint.

You can also wash your leaves with insecticidal soap. Make sure to look for pests under the leaves of the plants, too. This is a place where they like to hide.

If you want to air-dry your mint, then you should hang the stems upside down. Separate them into bundles secured with some string or a rubber band or spread them on a flat surface. When the leaves and stems feel crispy and dry, pluck off the leaves and put them into jars, Ziploc bags, or plastic containers with lids. [11] X Research source

Typically, you can harvest a larger harvest of mint about three times a season.

Serve it as a compliment to fish, chicken, lamb, or another protein dish. Use it to spice up veggies such as carrots, peas, and potatoes. Spice up salads such as fruit salads, fig and radish salads, or walnut and goat cheese salads. Use them in drinks such as iced tea, punch, or lemonade. Use the mint in cocktails, such as the mojito or the mint julep.
