Mint spreads aggressively through underground runners, so plant it in a container to control its growth. Learning how to grow mint is one of the easiest gardening tasks you can take on. This herb thrives with minimal care and rewards you with fresh leaves for teas, cocktails, and cooking.
Mint is practically indestructible. It grows in sun or shade, tolerates poor soil, and bounces back from neglect. But its vigor can become a problem if you don’t plan ahead. Follow these steps to enjoy a steady supply without letting it take over your garden.
Why Grow Mint At Home
Fresh mint tastes far better than store-bought. The leaves are more aromatic and flavorful. You can pick them exactly when you need them.
Mint plants are perennials in most climates. They return year after year with little effort. One plant can provide enough leaves for a family.
Growing your own mint saves money. A single packet of seeds or a small starter plant costs less than a few bunches from the grocery store. The plant will produce for years.
Choosing The Right Mint Variety
There are dozens of mint varieties. Each has a slightly different flavor and growth habit. Pick one that suits your needs.
Peppermint
Peppermint has a strong, cool flavor. It contains high levels of menthol. Use it for teas, desserts, and medicinal purposes.
Spearmint
Spearmint is milder and sweeter. It’s the classic choice for mojitos and mint juleps. It also works well in salads and sauces.
Chocolate Mint
Chocolate mint tastes like mint with a hint of cocoa. It’s great in desserts and hot chocolate. The leaves have a dark green color.
Apple Mint
Apple mint has a fruity, mild flavor. It’s good in fruit salads and drinks. The leaves are round and fuzzy.
Pineapple Mint
Pineapple mint has variegated leaves with white edges. It tastes like mint with a tropical note. Use it as a garnish or in teas.
How To Grow Mint From Seeds
Starting mint from seeds takes patience but is rewarding. Mint seeds are tiny and slow to germinate. Follow these steps for success.
- Fill small pots with seed-starting mix. Moisten the soil lightly.
- Sprinkle seeds on top of the soil. Do not cover them with soil; they need light to germinate.
- Press seeds gently into the surface. Mist with water.
- Cover pots with plastic wrap or a humidity dome. Place in a warm spot (65-70°F).
- Check daily for moisture. Remove cover once seedlings appear (10-15 days).
- Thin seedlings to one per pot when they have two sets of true leaves.
- Harden off plants gradually before transplanting outdoors.
Seeds can be started indoors 8-10 weeks before the last frost. Transplant after all danger of frost has passed.
How To Grow Mint From Cuttings
Cuttings are the fastest way to start mint. You can root them in water or soil. This method works almost every time.
Water Method
- Cut a 4-6 inch stem from a healthy mint plant. Remove lower leaves.
- Place the stem in a glass of water. Submerge the bottom nodes.
- Set the glass in indirect sunlight. Change water every few days.
- Roots will appear in 1-2 weeks. Transplant when roots are 1-2 inches long.
Soil Method
- Take a cutting as described above. Dip the cut end in rooting hormone (optional).
- Insert the cutting into moist potting soil. Firm the soil around it.
- Cover with a plastic bag to create humidity. Keep soil moist.
- Roots form in 2-3 weeks. Remove the bag after new growth appears.
How To Grow Mint In Containers
Container growing is the safest way to control mint. Without a barrier, mint will invade your entire garden. Use a pot with drainage holes.
Choose a container at least 12 inches wide. Mint roots spread quickly and need room. A larger pot means less frequent watering.
Use quality potting soil mixed with compost. Mint prefers slightly acidic to neutral pH (6.0-7.0). Add slow-release fertilizer at planting time.
Place the container where it gets 4-6 hours of sun daily. Mint tolerates partial shade but grows best with some direct light.
Water when the top inch of soil feels dry. Mint likes consistent moisture but not soggy roots. Check container plants daily in hot weather.
How To Grow Mint In The Ground
If you plant mint in the ground, contain it with barriers. Use a bottomless bucket or metal edging buried 12 inches deep. This stops runners from escaping.
Choose a spot with well-draining soil. Mint adapts to most soil types but prefers rich, loamy ground. Add compost before planting.
Space plants 18-24 inches apart. They will fill in quickly. Mint spreads by underground runners, so give it room.
Water regularly during dry spells. Mint needs about 1 inch of water per week. Mulch around plants to retain moisture and suppress weeds.
How To Grow Mint Indoors
Indoor mint provides fresh leaves year-round. It needs bright light and consistent care. Place it on a sunny windowsill or under grow lights.
Use a pot with drainage holes and a saucer. Fill with well-draining potting mix. Mint indoors grows slower than outdoors.
Water when the soil surface feels dry. Indoor air is often dry, so mist leaves occasionally. Fertilize monthly with a balanced liquid fertilizer.
Rotate the pot weekly to ensure even growth. Pinch off flower buds to keep the plant bushy. Harvest leaves regularly to encourage new growth.
How To Grow Mint: Care And Maintenance
Mint requires minimal care once established. Focus on watering, fertilizing, and pruning. These tasks keep plants healthy and productive.
Watering
Mint likes consistent moisture. Water deeply when the top inch of soil is dry. Avoid overhead watering to prevent fungal diseases.
In hot weather, container mint may need daily watering. Ground plants need less frequent watering. Check soil moisture regularly.
Fertilizing
Mint is a light feeder. Apply a balanced fertilizer (10-10-10) once in spring. Too much fertilizer reduces flavor intensity.
For container plants, use a diluted liquid fertilizer every 4-6 weeks during growing season. Stop fertilizing in fall.
Pruning
Regular pruning keeps mint bushy and prevents flowering. Pinch off the top two sets of leaves every few weeks. This encourages branching.
Cut back plants by one-third in midsummer if they look leggy. Remove flower stalks as soon as they appear. Flowering reduces leaf quality.
Winter Care
Mint goes dormant in cold climates. Cut back dead stems after frost. Mulch heavily to protect roots from freezing.
Container mint can be moved to a garage or basement for winter. Water sparingly during dormancy. New growth appears in spring.
Common Problems When Growing Mint
Mint is generally pest-free but can have issues. Identify problems early to keep plants healthy.
Pests
- Aphids: Small insects on new growth. Spray with insecticidal soap or water jet.
- Spider mites: Fine webbing on leaves. Increase humidity and use neem oil.
- Mint root borers: Larvae that tunnel into stems. Remove and destroy affected plants.
Diseases
- Powdery mildew: White coating on leaves. Improve air circulation and avoid overhead watering.
- Mint rust: Orange spots on leaves. Remove infected leaves and avoid crowding.
- Root rot: Yellowing leaves and mushy roots. Improve drainage and reduce watering.
Growth Issues
- Leggy growth: Not enough light. Move to a sunnier spot.
- Yellow leaves: Overwatering or nutrient deficiency. Adjust watering and fertilize.
- Slow growth: Compacted soil or root bound. Repot or loosen soil.
Harvesting Mint
Harvest mint leaves once the plant is 6-8 inches tall. Pick leaves in the morning when oils are strongest. Use sharp scissors or pinch with fingers.
Harvest regularly to promote bushy growth. Never remove more than one-third of the plant at once. Leave enough leaves for photosynthesis.
For large harvests, cut stems at the base. New growth will emerge from the roots. You can harvest 3-4 times per growing season.
Store fresh mint in a glass of water in the refrigerator. Change water every few days. Leaves stay fresh for up to a week.
Dry mint by hanging bundles upside down in a dark, airy space. Crumble leaves once dry and store in airtight jars. Dried mint lasts for months.
Using Mint In The Kitchen
Fresh mint adds flavor to sweet and savory dishes. Use it in teas, salads, sauces, and desserts. Mint pairs well with lamb, peas, and chocolate.
Make simple mint tea by steeping fresh leaves in hot water. Add honey and lemon for extra flavor. Iced mint tea is refreshing in summer.
Add chopped mint to fruit salads, yogurt, or smoothies. It brightens flavors and adds a cooling sensation. Mint also works in pesto instead of basil.
Freeze mint leaves in ice cubes for drinks. Chop leaves and mix with butter for compound butter. Mint jelly is a classic condiment for lamb.
