Growing mint indoors is a rewarding and straightforward endeavor. With a few basic steps, you can enjoy fresh mint all year round. Whether you’re a beginner or an experienced gardener, this guide will walk you through the entire process.

Why Grow Mint Indoors?

Growing mint indoors ensures you have a constant supply of this versatile herb. Mint adds a burst of flavor to dishes, teas, and even cocktails. Additionally, indoor gardening allows for year-round cultivation, free from pests and harsh weather. Here are some key benefits:

  • Accessibility: Fresh mint at your fingertips, whenever you need it.
  • Control: Manage the growing conditions, including light, water, and soil.
  • Aesthetics: Mint adds greenery and a pleasant aroma to your indoor space.
  • Health Benefits: Mint is known for its digestive, anti-inflammatory, and soothing properties.

Getting Started

Choosing the Right Mint Variety

There are many types of mint, each with unique flavors and uses. Some popular varieties include:

  • Spearmint: Commonly used in cooking and teas, with a mild, sweet flavor.
  • Peppermint: Stronger and more intense, often used in candies and medicinal teas.
  • Chocolate Mint: Has a subtle chocolate undertone, great for desserts.
  • Apple Mint: Slightly fruity, perfect for beverages and salads.

Consider your culinary preferences and growing conditions when selecting a variety. You can even grow multiple types if space allows.

Selecting a Container

Choosing the right container is crucial for successful mint cultivation. Here are some tips:

  • Size: A pot that is 8-10 inches in diameter is ideal for mint’s spreading root system.
  • Material: Terracotta pots are great for their breathability, but plastic pots retain moisture longer.
  • Drainage: Ensure the pot has drainage holes to prevent waterlogging, which can lead to root rot.

Soil Requirements

Mint thrives in well-draining soil. Here’s how to prepare the perfect soil mix:

  • Potting Mix: Use a high-quality potting mix designed for herbs or vegetables.
  • Organic Matter: Enrich the soil with compost or well-rotted manure.
  • Aeration: Add perlite or sand to improve soil drainage and aeration.

Avoid heavy garden soils that retain too much moisture, as they can suffocate the roots.

Planting Mint

Propagating from Cuttings

Propagating mint from cuttings is a cost-effective and straightforward method. Follow these steps:

  1. Select a Healthy Stem: Choose a healthy stem from an existing mint plant, ideally one that is at least 4-6 inches long.
  2. Cut Below a Node: Use sharp, sterilized scissors or pruning shears to cut just below a leaf node (the point where leaves attach to the stem).
  3. Remove Lower Leaves: Strip the leaves from the bottom half of the cutting to prevent them from rotting in the water.
  4. Place in Water: Put the cutting in a glass of water, ensuring the node is submerged. Change the water every few days to keep it fresh.
  5. Transplant to Soil: Once roots develop (usually within 1-2 weeks), plant the cutting in your prepared pot, burying the roots and firming the soil around the stem.

Planting from Seeds

Starting mint from seeds requires patience but can be very rewarding. Here’s how to do it:

  1. Fill the Pot with Soil: Leave about an inch of space at the top.
  2. Sow the Seeds: Scatter mint seeds over the soil surface. Mint seeds are tiny, so handle them with care.
  3. Cover Lightly: Sprinkle a thin layer of soil over the seeds, no more than 1/8 inch thick.
  4. Water Gently: Moisten the soil with a fine mist spray to avoid disturbing the seeds.
  5. Provide Light: Place the pot in a sunny spot or under a grow light. Mint seeds need light to germinate, so do not cover them too deeply.

Planting from Store-Bought Plants

If you prefer a quicker start, you can purchase young mint plants from a nursery or garden center. Here’s how to transplant them:

  1. Prepare the Pot: Fill your chosen container with potting mix, leaving space for the plant.
  2. Remove the Plant: Gently remove the mint plant from its nursery pot, being careful not to damage the roots.
  3. Plant in the New Pot: Place the plant in the center of the pot, fill around it with soil, and firm it down gently.
  4. Water Thoroughly: Water the plant well to help it settle into its new home.

Caring for Your Mint Plant


Mint prefers consistently moist soil, but not soggy. Here’s how to water your mint correctly:

  • Check Soil Moisture: Stick your finger into the soil up to the first knuckle. If it feels dry, it’s time to water.
  • Water Evenly: Water the plant thoroughly until water drains out of the bottom of the pot. Ensure the entire root zone gets moisture.
  • Avoid Overwatering: Let the top inch of soil dry out between waterings to prevent root rot.


Mint needs at least 6 hours of sunlight daily. Here’s how to provide the right lighting conditions:

  • Natural Light: Place the pot near a south-facing window where it can receive direct sunlight.
  • Artificial Light: If natural light is insufficient, use a fluorescent or LED grow light. Position the light 6-12 inches above the plant.
  • Rotate the Pot: Rotate the pot every few days to ensure even light exposure and prevent the plant from leaning.

Temperature and Humidity

Mint is quite hardy but prefers certain conditions:

  • Temperature: Keep the indoor temperature between 60-70°F (15-21°C).
  • Humidity: Mint enjoys moderate humidity. If the air is dry, place a humidifier nearby or use a pebble tray with water under the pot.


Feed your mint plant to encourage healthy growth. Here’s how:

  • Type of Fertilizer: Use a balanced, water-soluble fertilizer (10-10-10 or similar).
  • Frequency: Fertilize every 4-6 weeks during the growing season (spring and summer).
  • Application: Dilute the fertilizer to half the recommended strength to avoid over-fertilizing, which can lead to excessive leaf growth with diminished flavor.

Pruning and Harvesting

Regular Pruning

Prune your mint regularly to encourage bushy growth and prevent legginess. Here’s how:

  • Timing: Prune every few weeks, or whenever the plant looks overgrown.
  • Method: Use sharp scissors to cut back the stems just above a leaf node. This will stimulate new growth from the cut point.
  • Remove Flowers: Pinch off any flower buds as they appear to keep the plant focused on producing leaves.


Harvest mint leaves as needed. Here are some tips for the best results:

  • Morning Harvest: Pick leaves early in the morning for the best flavor and aroma.
  • Selective Harvesting: Pluck individual leaves or cut sprigs with sharp scissors.
  • Avoid Over-Harvesting: Do not harvest more than one-third of the plant at a time to keep it healthy and productive.

Common Issues and Solutions


Although indoor plants are less prone to pests, they can occasionally suffer from infestations. Here’s how to handle common pests:

  • Aphids: Tiny, sap-sucking insects that cluster on new growth. Spray with insecticidal soap or rinse off with water.
  • Spider Mites: Minute pests that cause stippling and webbing. Increase humidity and use neem oil or insecticidal soap.
  • Whiteflies: Small, white flying insects. Use yellow sticky traps and spray with neem oil.


Mint can suffer from several diseases. Here’s how to prevent and treat them:

  • Powdery Mildew: A white, powdery fungus on leaves. Ensure good air circulation, avoid overhead watering, and treat with a fungicide if necessary.
  • Rust: Orange or brown spots on leaves. Remove affected leaves and improve air circulation. Use a fungicide if needed.
  • Root Rot: Caused by overwatering. Ensure proper drainage and let the soil dry out between waterings.

Nutrient Deficiencies

Sometimes, mint may show signs of nutrient deficiencies. Here’s what to look for and how to fix it:

  • Yellow Leaves: Could indicate nitrogen deficiency. Use a balanced fertilizer.
  • Stunted Growth: May be due to lack of phosphorus. Apply a fertilizer high in phosphorus.
  • Poor Leaf Color: If leaves are pale, it might be an iron deficiency. Use a micronutrient fertilizer.
