Planting mint and basil is easy once you understand a few simple rules that set these two herbs apart.
Mint and basil are two of the most rewarding herbs you can grow, but they have totally different personalities.
Mint is a vigorous spreader that will take over your garden if you let it, while basil is a sun-loving annual that thrives with regular harvesting.
In this post, we’ll break down how to plant mint and basil step by step, covering soil, sunlight, watering, and the best containers for each.
Let’s dig in so you can enjoy fresh herbs all season long.
Why Understanding How to Plant Mint and Basil Matters
The biggest mistake gardeners make is treating mint and basil the same way when you plant them.
Basil needs hot, direct sun and well-drained soil, while mint prefers partial shade and consistently moist ground.
Knowing how to plant mint and basil correctly from day one prevents yellowing leaves, leggy growth, and bitter flavors later.
When you master how to plant mint and basil, you’ll have a nonstop supply of fragrant leaves for teas, pesto, salads, and garnishes.
1. Choosing the Right Location for Mint and Basil
Start by picking separate spots because mint and basil have conflicting sunlight needs.
Basil loves 6 to 8 hours of full, blazing sun each day to produce those big, flavorful leaves.
Mint, on the other hand, actually prefers morning sun with afternoon shade, especially in hot climates.
If you’re wondering how to plant mint and basil in the same garden bed, it’s tricky, so consider separate containers instead.
That way, you can place the mint in a shadier corner while the basil bakes in the sun.
2. Preparing the Soil Before You Plant Mint and Basil
Both herbs want loose, fertile soil with good drainage, but mint is more forgiving than basil.
For basil, mix in plenty of compost to create rich, crumbly soil that holds moisture without staying soggy.
Mint also appreciates compost, but it can tolerate heavier, clay-like earth that basil would quickly reject.
Aim for a pH between 6.0 and 7.0 for both, which is slightly acidic to neutral.
Work the soil to a depth of about 8 to 10 inches before planting mint and basil so roots can spread easily.
3. The Best Time to Plant Mint and Basil Outdoors
Timing is everything when you plant mint and basil, so don’t rush the season.
Basil is extremely frost-tender, so wait until nighttime temperatures stay above 50°F (10°C) every single night.
Mint is much hardier and can handle a light frost, so you can plant mint a few weeks earlier than basil in spring.
If you can’t plant mint and basil directly in the ground yet, start them indoors in small pots under a sunny window.
Move them outside gradually over a week to harden them off and prevent transplant shock.
How to Plant Mint Step by Step
Let’s focus specifically on mint first, since it has a reputation for being both easy and invasive.
1. Containers Are Your Best Friend for Mint
The single most important rule for how to plant mint is to always use a container or a buried pot.
Mint sends out aggressive runners that travel underground and pop up everywhere, far from the original plant.
Plant mint in a pot that’s at least 10 inches wide and 8 inches deep to give roots room to breathe.
You can also sink the pot into the ground, leaving the rim slightly above the soil line, to stop runners from escaping.
2. Planting Mint Seedlings or Cuttings
Mint is best grown from cuttings or nursery seedlings, not seeds, because seeds often produce weak or hybrid plants.
Take a 4- to 6-inch cutting from a healthy mint plant and remove the lower leaves before planting.
Place the cutting in a glass of water for a week until roots form, then transplant it into moist potting mix.
Space multiple mint plants about 18 inches apart if they’re in a large container, so each gets good airflow.
Water thoroughly after planting mint and keep the soil consistently damp for the first couple of weeks.
3. How to Care for Mint After Planting
Once your mint is planted, maintenance is honestly minimal compared to basil.
Keep the soil evenly moist, never bone-dry but never waterlogged either, since mint hates sitting in puddles.
Trim the stems regularly to encourage bushy growth and prevent the plant from becoming leggy and woody.
Pinch off any flower buds as soon as you see them because flowering signals the leaves to turn bitter.
Mint is a perennial in most zones, so it will die back in winter and return fresh again in spring.
How to Plant Basil for Maximum Flavor
Now let’s switch gears to basil, which is a completely different beast when you plant it.
1. Start Basil Indoors or Buy Strong Seedlings
Basil seeds are tiny and slow to germinate, so many gardeners prefer to buy established seedlings.
If you do start basil from seed, sow them about ¼ inch deep in small trays filled with seed-starting mix.
Keep the trays warm at around 70–75°F and mist the soil daily to keep it moist but not dripping.
Seeds will sprout in 5 to 10 days, then you can thin them out to leave the strongest one per cell.
Once the seedlings have two sets of true leaves, they’re ready to plant out in the garden or a pot.
2. Planting Basil in the Ground or Containers
Basil thrives in large pots or directly in raised beds, as long as the drainage is excellent.
Space basil plants 12 to 18 inches apart because they grow into bushy, branching little shrubs.
Dig a hole twice the size of the root ball, place the seedling in, and backfill with soil up to the first leaves.
Water deeply right after planting basil, then let the top inch of soil dry out before watering again.
Basil hates wet feet, so overwatering is the quickest way to cause root rot and mushy stems.
3. The Secret to Caring for Basil After Planting
Basil demands regular harvesting to stay healthy and productive, so don’t be shy about snipping leaves.
When you harvest, cut just above a set of leaves rather than pulling from the stem’s base.
This encourages the plant to branch out into two new stems, giving you double the leaves next time.
Feed basil every two weeks with a diluted liquid fertilizer, especially if it’s growing in a container.
Basil is an annual, meaning it completes its life cycle in one season, so replant each year from seed or seedlings.
Common Mistakes to Avoid When Planting Mint and Basil
Even experienced gardeners mess up when they plant mint and basil together, so watch out for these errors.
1. Letting Mint Run Wild in the Garden
This is the number one disaster when you plant mint without a barrier.
Mint roots can travel up to 3 feet in a single season, strangling nearby herbs like basil.
Always confine mint to a container or a buried pot with no drainage holes at the bottom to contain runners.
2. Watering Basil Too Much or Too Little
Basil is finicky about moisture, and both extremes cause problems.
Too much water leads to drooping, yellow leaves and root rot, while too little causes wilting and crispy edges.
Stick your finger into the soil up to your first knuckle, and only water if that top inch feels dry.
In hot summer weather, you might need to water basil every single day, especially in pots.
3. Forgetting to Pinch Flowers on Both Herbs
When basil and mint bolt to flower, the leaves lose their essential oils and become tough and bitter.
So check your plants every few days and pinch any flower buds immediately.
Regular clipping of the growing tips delays flowering and keeps both herbs tender and flavorful.
So, How Do You Plant Mint and Basil Successfully?
Planting mint and basil successfully comes down to respecting their different personalities.
Mint thrives in moist shade with aggressive confinement, while basil craves full sun and fast-draining soil.
Use pots for mint, rich compost for basil, and always maintain consistent but not excessive watering.
When you plant mint and basil the right way, you’ll be rewarded with months of fresh, aromatic harvests.
So grab your pots, your seeds, and your sunny windowsill, and start planting mint and basil today.
Happy gardening, and enjoy every single leaf you grow!
