You can grow mint and basil indoors successfully with the right light, water, and soil, and it’s easier than you might think.
If you’ve been wondering how to grow mint and basil indoors, the short answer is that both herbs thrive on a sunny windowsill with consistent care.
Growing mint and basil indoors lets you snip fresh leaves for teas, sauces, and salads all year round, no matter the season outside.
In this post, we’ll break down exactly how to grow mint and basil indoors, covering everything from containers and light to watering and harvesting.
Let’s dig in and get your kitchen garden started.
How to Grow Mint and Basil Indoors: The Basics That Work
When you learn how to grow mint and basil indoors, the first thing to understand is that these two herbs have slightly different personalities, but they share the same core needs.
Both mint and basil love bright light, well-draining soil, and steady moisture, so mastering these three pillars is the secret to success.
If you’re new to indoor gardening, you’ll be happy to know that neither plant is fussy about fancy equipment once you get the essentials right.
Let’s explore each element so you can grow mint and basil indoors with confidence.
1. Start With the Right Containers for Growing Mint and Basil Indoors
Choosing the right pot is a big part of how to grow mint and basil indoors because these herbs hate sitting in waterlogged soil.
For mint, always use a pot with drainage holes, and consider a wider container since mint loves to spread its roots.
For basil, a pot that’s at least 6 to 8 inches deep gives the taproot enough room to grow strong.
Make sure each pot has a saucer underneath to catch excess water, but empty the saucer after watering to prevent root rot.
Terracotta pots are great for basil because they allow soil to dry slightly between waterings, which basil appreciates.
Mint, on the other hand, does better in plastic or glazed ceramic pots that hold moisture a bit longer.
2. Give Your Mint and Basil the Perfect Indoor Light
Light is the most critical factor when you want to grow mint and basil indoors, and both plants crave at least 6 to 8 hours of bright, direct sun daily.
A south-facing windowsill is your best bet, offering the intense light that mimics their natural sunny habitats.
If you don’t have a sunny window, you can still grow mint and basil indoors by using grow lights placed a few inches above the plants.
Keep the lights on for 12 to 14 hours a day, and you’ll see your herbs respond with lush, vibrant growth.
Watch for leggy stems, which are a sure sign your mint or basil isn’t getting enough light.
Rotate your pots every few days so all sides of the plant get even exposure and grow evenly.
3. Master the Right Soil Mix for Indoor Mint and Basil
The soil you use directly affects how well you can grow mint and basil indoors, so don’t just grab any garden dirt.
A high-quality potting mix that’s light and fluffy is ideal because it drains well while still holding onto some moisture.
You can even mix in a bit of perlite or coarse sand to improve drainage and aeration for both herbs.
Avoid heavy garden soil, which compacts easily and can suffocate the roots of your indoor plants.
If you want to boost nutrients, add a thin layer of compost to the top of the soil when you first pot your herbs.
Watering and Feeding Your Indoor Mint and Basil
Watering is where most people struggle when they try to grow mint and basil indoors, so let’s get it right.
The golden rule is to water when the top inch of soil feels dry to the touch, not on a strict schedule.
Mint likes consistently moist soil, so don’t let it dry out completely, but never leave it standing in water.
Basil prefers slightly drier conditions between waterings, so check the soil with your finger every couple of days.
When you do water, do it thoroughly until water runs out of the drainage holes, then dump the excess.
As for feeding, both herbs benefit from a diluted liquid fertilizer every 4 to 6 weeks during the growing season.
Don’t overdo it with fertilizer, because too much can make basil taste bitter and mint lose its aromatic oils.
Pruning and Harvesting to Keep Your Indoor Herbs Thriving
Once you’ve mastered watering, the next step in how to grow mint and basil indoors is regular pruning and harvesting.
Harvesting isn’t just about getting leaves for your cooking; it actually encourages your plants to grow bushier and fuller.
For basil, always pinch off the top set of leaves just above a pair of lower leaves, which promotes branching.
Never strip basil down to bare stems, as the plant needs some leaves left to photosynthesize and stay healthy.
For mint, you can trim entire stems back by about one-third, and new growth will sprout from the cut points.
Harvest mint and basil in the morning when essential oils are at their peak for the best flavor and aroma.
Regular harvesting also prevents your indoor herbs from flowering, which makes leaves turn tough and less tasty.
1. Watch for Pests and Problems While Growing Mint and Basil Indoors
Even indoors, you might encounter a few pests, so learn to spot them early when you grow mint and basil indoors.
Aphids, spider mites, and whiteflies are the most common invaders, and they love the tender new growth of your herbs.
Inspect the undersides of leaves weekly, since that’s where these tiny pests like to hide and feed.
If you see small webs, sticky residue, or yellowing leaves, act fast to prevent an infestation from spreading.
A simple spray of water with a few drops of dish soap can knock out most pests, just rinse after a few hours.
Yellow leaves can also mean overwatering, so adjust your schedule if you notice that symptom in your herbs.
