How to Grow Mint from Cuttings: Fast & Easy Guide

By Marcus Williams · January 24, 2026

To grow mint from cuttings, take a 4–6 inch stem cutting from a healthy plant, remove the lower leaves, and place it in water or moist soil. Roots typically develop within 1–2 weeks, after which the new plant can be potted or transplanted outdoors.

Why Grow Mint from Cuttings?

Propagating mint from cuttings is faster and more reliable than growing from seeds. Mint plants grown from cuttings are genetically identical to the parent, ensuring consistent flavor, aroma, and growth habits.

Cuttings root quickly, often in under 14 days
No need for pollinators or seed harvesting
Preserves desirable traits of parent plant
Ideal for indoor and outdoor gardens

Selecting the Right Stem Cutting

Choosing a healthy stem is crucial for successful propagation.

Characteristics of a Good Mint Cutting

4–6 inches long with multiple leaf nodes
Taken from non-flowering stems
Firm, green stems (avoid woody or discolored parts)
Free from pests or disease signs

Step-by-Step Guide to Rooting Mint Cuttings

In Water

Cut just below a leaf node using clean scissors
Remove leaves from the bottom 2–3 inches
Place in a clean glass of water
Change water every 2–3 days
Keep in bright, indirect light
Transplant once roots reach 1–2 inches (7–14 days)

In Soil

Prepare a small pot with well-draining potting mix
Insert cutting 2–3 inches deep
Water thoroughly and cover with a plastic bag to retain humidity
Place in bright, indirect light
Mist regularly and keep soil moist
Check for resistance when gently tugged (indicating root formation) after 10–14 days

Optimal Conditions for Mint Cutting Success

Mint thrives in specific environmental conditions that encourage rapid root development.

Light: Bright, indirect sunlight (4–6 hours daily)
Temperature: 65–75°F (18–24°C)
Humidity: Moderate to high; use plastic covers if needed
pH: Slightly acidic to neutral (6.0–7.0)

Propagation Method	Average Rooting Time	Success Rate (%)	Best Season
Water	7–10 days	85	Spring to Early Fall
Soil	10–14 days	75	Spring to Summer
Hydroponic	5–8 days	90	Year-Round (Indoor)
Rooting Hormone + Soil	7–10 days	88	Spring

Table data source:1, 2

The data shows that hydroponic and rooting hormone methods yield the highest success rates and fastest rooting times. However, water propagation remains highly effective and accessible for home gardeners without specialized supplies.

Caring for Newly Rooted Mint Plants

After roots form, proper care ensures strong establishment.

Gradually acclimate to direct light over 5–7 days
Use nutrient-rich, well-draining soil
Water when top inch of soil feels dry
Fertilize lightly every 4–6 weeks with balanced liquid fertilizer
Pinch tips to encourage bushy growth

Common Mistakes to Avoid When Growing Mint from Cuttings

Using old or diseased stems
Leaving too many leaves on submerged portion
Overwatering in soil, leading to rot
Placing in direct sunlight during rooting
Waiting too long to transplant rooted cuttings

Frequently Asked Questions About Growing Mint from Cuttings

Can I grow mint from cuttings year-round?

Yes, mint cuttings can be grown year-round indoors with adequate light and warmth. Outdoors, spring and early summer are ideal due to favorable temperatures and daylight length.

How long does it take for mint cuttings to root?

Mint cuttings typically root in 7–14 days. In water, roots appear in 7–10 days; in soil, it may take up to 14 days. Using rooting hormone can reduce this time by 2–3 days.

Do mint cuttings need sunlight to root?

Yes, but not direct sunlight. Place cuttings in bright, indirect light to promote photosynthesis without overheating or drying out the cutting.

Can I use tap water for rooting mint cuttings?

Yes, most tap water is suitable. However, if your water is heavily chlorinated or contains high fluoride, let it sit uncovered for 24 hours before use to allow chemicals to dissipate.

Why is my mint cutting turning brown or mushy?

Browning or mushiness usually indicates rot due to stagnant water, overwatering in soil, or bacterial growth. Change water frequently, ensure good air circulation, and avoid overcrowding cuttings.

Propagating mint from cuttings is an easy, cost-effective way to expand your herb garden. With proper technique and care, you can enjoy fresh mint year after year.
