Indoor Growing Basics

Mint plants belong to the genus Mentha and are fast-growing perennial herbs that produce beautiful flowers in late summer. They spread mainly through runners and underground rhizomes, making them ideal for container growth indoors.

Garden mint plants prefer moist soil with a neutral pH and can tolerate full to part sun exposure with some shade relief from intense afternoon sunlight. Regularly pinching the stems promotes branching, resulting in full and bushy plants.

Propagation Tips

There are several ways to propagate mint indoors, including root divisions, stem cuttings, and hydroponic cultivation. Here are some tips for each type of propagation:

From Root Divisions

Divide mature plants in late summer.
Cut the root ball into quarters with stems and roots intact.
Trim roots and stems, then plant in containers with well-draining soil.

From Stem Cuttings

Take 4-6 inch cuttings from healthy plants.
Remove leaves, dip ends in rooting hormone, and plant in a potting mix.
Allow cuttings to root for 6-8 weeks before bringing indoors.

Stem Cuttings in Water

Place stem cuttings in water-filled jars in a sunny spot.
Change water every other day and add liquid fertilizer once roots are established.
Stop fertilizing in mid-winter to promote new growth.

How to Grow

To ensure optimal growth of your indoor mint plants, consider the following guidelines:

Light, Location, and Temperature

Provide bright, indirect light for 4-6 hours per day.
Maintain temperatures of 65-70°F during the day and 55-60°F at night.
Rotate plants weekly to promote even growth.

Food, Humidity, and Water

Allow the top inch of soil to dry between waterings.
Maintain indoor humidity at around 45%.
Feed plants lightly with a half-strength fertilizer every 3-4 weeks.

How to Harvest

Harvesting mint indoors is key to promoting new growth and ensuring a steady supply of leaves. Here are some tips for harvesting your mint plants:

Trim stems regularly to encourage branching.
Cut back stems by half when they reach 4-8 inches in length.
Store excess mint in the refrigerator in an airtight container.

By following these guidelines, you can enjoy fresh and flavorful mint year-round by growing a few plants indoors. Experiment with different varieties and let us know your favorites in the comments!
