How to Grow Mint and Basil Indoors: The Key Basics

The core of how to grow mint and basil indoors comes down to giving each plant what it naturally craves.
 
Both mint and basil are sun lovers, but they have slightly different personalities when it comes to soil and moisture.
 
Here’s the good news: neither plant is fussy, so even beginners can succeed with the right setup.
 
Let’s break down the essentials for each herb so you can master how to grow mint and basil indoors without any guesswork.
 

1. Pick the Right Containers and Drainage

When you learn how to grow mint and basil indoors, the container choice matters more than you think.
 
Mint is a vigorous spreader, so give it a pot that’s at least 8–10 inches wide with plenty of room for roots.
 
Basil prefers a slightly snugger pot, around 6–8 inches, because its root system is more compact.
 
Make sure every pot has drainage holes because both herbs hate sitting in soggy soil.
 
If you’re planning how to grow mint and basil indoors together, you can use separate pots to avoid mint overwhelming basil.
 

2. Choose the Best Soil Mix

A light, well-draining potting mix is the secret to successful indoor herbs.
 
Use a high-quality potting mix designed for containers, not garden soil, which can compact and harbor pests.
 
Add a bit of perlite or coarse sand to improve drainage and aeration.
 
Mint tolerates slightly richer soil, while basil prefers a leaner mix that doesn’t hold too much water.
 
This balance is a big part of how to grow mint and basil indoors that stay healthy and productive.
 

3. Provide Intense Light

Light is the single most important factor in how to grow mint and basil indoors successfully.
 
Both herbs need at least 6–8 hours of bright, direct sunlight each day to produce flavorful leaves.
 
A south-facing windowsill is ideal, but if you don’t have one, use a grow light for 12–14 hours a day.
 
Rotate your pots every few days so each side gets even light and your plants don’t lean.
 
Without enough light, basil gets leggy and mint becomes sparse, so don’t skimp on this step.
 

4. Master the Watering Routine

Watering is where most people struggle when figuring out how to grow mint and basil indoors.
 
Mint likes consistently moist soil, so water it whenever the top inch feels dry to the touch.
 
Basil is a bit more forgiving but still prefers even moisture, never letting the soil dry out completely.
 
Always water at the base of the plant, not over the leaves, to prevent fungal issues.
 
A good trick is to stick your finger in the soil; if it’s dry at knuckle depth, it’s time to water.
 
Overwatering is deadly, so make sure excess water drains away and never leaves pots sitting in a saucer of water.
 

5. Keep Temperatures Cozy

Temperature plays a big role in how to grow mint and basil indoors year-round.
 
Both herbs prefer daytime temperatures between 65–75°F (18–24°C) and slightly cooler nights.
 
Avoid placing them near drafty windows, heat vents, or air conditioners, as sudden temperature swings stress the plants.
 
If your home stays within this range, your herbs will grow steadily and produce abundant leaves.
 
This stable environment mimics their native Mediterranean and temperate climates perfectly.
 

Best Practices to Grow Mint and Basil Indoors Without Pests

Healthy plants resist pests, but indoor herbs can still attract unwanted visitors like aphids and spider mites.
 
The best way to avoid these issues is to inspect new plants before bringing them inside.
 
If you see pests, wipe leaves with a mild soapy water solution or use neem oil as a natural treatment.
 
Also, keep air circulation moving by opening a window occasionally or using a small fan.
 
These proactive habits are part of smart how to grow mint and basil indoors strategies that keep your harvest safe.
 

Harvesting Tips for Continuous Growth

Harvesting correctly encourages bushier growth, which is the reward of understanding how to grow mint and basil indoors.
 
For basil, pinch off leaves just above a pair of leaf nodes, and this tells the plant to branch out.
 
For mint, snip stems just above a leaf pair, and always remove any flower buds before they open.
 
Flowering makes leaves taste bitter, so regular harvesting keeps your herbs sweet and productive.
 
You can start harvesting once your plants have at least six true leaves, usually within a few weeks.
 
Never take more than one-third of the plant at a time, and you’ll enjoy fresh herbs for months.
 
This method turns a simple pot into a continuous supply, which is the whole point of growing mint and basil indoors.
