How to Grow Herbs in Pots: The Complete Guide


Herbs growing indoors in an herb garden kit

Growing herbs in pots is one of the easiest and most reliable ways to produce fresh flavor at home. Herbs thrive in containers when gardeners provide three essentials:

  • Excellent drainage
  • Quality potting mix
  • Consistent sunlight

The Herb Market Continues to Grow

More than 14 million U.S. households grow herbs, according to the National Gardening Association. Interest in container herb gardening continues to rise as homeowners seek small-space growing solutions and fresher ingredients.

The fresh herbs market has experienced steady growth in recent years, driven by increased home cooking, plant-forward diets, and demand for fresh flavor. For example, the North American fresh herb market had a revenue of USD 1.25 billion in 2023. It’s expected to grow at a CAGR of 8.4% through 2030 (Source: Grand View Research).

Herbs remain one of the highest-value crops per square foot for home gardeners. Growing herbs in pots allows gardeners to produce consistent yields in patios, balconies, and small yards without dedicating a full garden bed.

“Herbs are one of the most forgiving crops you can grow in containers, but consistency matters. When soil structure and watering stay balanced, production improves dramatically.” — Mark Bolt, VP of EarthBox®

This guide explains exactly how to grow herbs in pots indoors or outdoors, how to group them properly, and how to avoid the most common mistakes.

Quick Start: How to Grow Herbs in Pots

If you want the fast version, follow these five rules:

  1. Use a pot at least 8 to 10 inches deep with drainage holes.
  2. Fill it with high-quality potting mix, not garden soil.
  3. Provide 6 to 8 hours of sunlight for most culinary herbs.
  4. Water when the top inch of soil feels dry.
  5. Harvest regularly to keep plants bushy and productive.

Everything else in this guide expands on those fundamentals.

“Most herb problems trace back to one of those five basics. Get pot size, drainage, light, soil, and watering right, and herbs reward you quickly.” — Mark Bolt, VP of EarthBox®

What Are the Best Herbs to Grow in Pots?

The best herbs to grow in pots are compact, versatile plants that thrive in well-drained potting soil and controlled watering conditions.

Most container-friendly herbs fall into two categories: Mediterranean herbs that prefer drier soil and leafy herbs that prefer consistent moisture.

Top Mediterranean Herbs for Containers

  • Rosemary
  • Thyme
  • Sage
  • Oregano

Fast-Growing Container Herbs

  • Basil
  • Mint
  • Chives

These herbs grow quickly and prefer steady moisture and regular harvesting.

Mint should always be grown in its own pot because it spreads aggressively and can overtake other herbs.

Basil is one of the easiest herbs to grow in pots. For variety selection and pruning strategies, see Growing Basil in Containers.

How Big Should a Pot Be for Herbs?

Most culinary herbs need pots at least 6 to 8 inches deep to support healthy root growth and proper drainage.

Larger, fast-growing herbs require more space. When in doubt, choose a slightly larger container. Herbs rarely struggle from too much root room, but they often suffer in pots that are too small.

“Root space is insurance. When roots have room to grow, moisture and nutrient balance become much easier to manage.” — Mark Bolt, VP of EarthBox®

Herb Pot Size Guidelines

Herb pot size depends on how fast the plant grows and how large its root system becomes. Choosing the right container prevents overcrowding, improves drainage, and supports long-term growth.

Small, Slow-Growing Herbs

Best in 6–8 inch pots:

  • Thyme
  • Chives
  • Marjoram

These herbs have compact root systems and adapt well to smaller containers.

Larger, Faster-Growing Herbs

Best in 10–12 inch pots or larger:

  • Basil
  • Rosemary
  • Mint
  • Parsley

These herbs grow quickly and need extra soil volume to prevent overcrowding and root-bound plants.

Rule: Always prioritize depth. Herbs need room for root development more than surface width.

Why Drainage Matters for Potted Herbs

Drainage holes are essential for growing herbs in pots.

Without drainage, water collects at the bottom of the container. Standing water causes root rot and weak growth.

Always choose containers with built-in drainage holes. If a pot does not have holes, drill them before planting.

Choosing the Right Pot Material

Container material directly affects how quickly soil dries, how often you need to water, and how stable moisture remains around the roots.

Some materials allow soil to breathe and dry faster. Others retain moisture longer, reducing the need for watering. Choosing the right material helps you match the pot to the herb’s natural growing conditions.

Terra Cotta

Terra cotta is porous. It allows moisture to evaporate through the pot's sides.

This makes terra cotta ideal for Mediterranean herbs such as:

  • Rosemary
  • Thyme
  • Sage
  • Oregano

These herbs prefer soil that dries slightly between watering. Faster evaporation helps prevent root rot.

The tradeoff: terra cotta dries quickly in hot weather and may require more frequent watering.

Plastic or Glazed Ceramic

Plastic and glazed pots are non-porous. They retain moisture longer and reduce evaporation.

These materials work well for herbs that prefer steady moisture, such as:

  • Basil
  • Parsley
  • Mint

The tradeoff: poor drainage combined with moisture-retentive materials increases the risk of overwatering.

Quick Recap: Use terra cotta for Mediterranean herbs that prefer drier soil. Use plastic or glazed pots for leafy herbs that prefer steadier moisture.

Which Pot Material Is Best for Herbs?

There’s no single best material for growing herbs in pots. The right choice depends on the herb’s water preference and your climate.

Rule:

  • Use breathable pots for drought-tolerant herbs.
  • Use moisture-retaining pots for leafy, fast-growing herbs.

Why Depth Is More Important Than Width

Shallow pots restrict root growth and dry out quickly.

Deep containers improve:

  • Root stability
  • Moisture balance
  • Nutrient access
  • Long-term plant health

Using a container that is too small limits root development, resulting in weak, stressed plants.

Depth Rule: If you choose between a wide, shallow container and a deeper one, always choose the deeper one. Deep containers stabilize moisture and protect roots from stress.

What Is the Best Soil for Growing Herbs in Pots?

The biggest mistake gardeners make is using garden soil in containers.

Garden soil compacts in pots. Compacted soil suffocates roots and traps water.

Use this formula instead:

  • 2 parts high-quality potting mix
  • 1 part perlite or coarse grit

This blend improves drainage, aeration, and root oxygenation.

Most herbs prefer a pH between 6.0 and 7.0. A balanced potting mix typically falls within that range.

For a deeper dive into soil selection, read Container Gardening: The Best Soil for Containers.

Soil Rule: Never use garden soil in containers. Use potting mix with added perlite or grit to keep roots oxygenated and prevent waterlogged soil.

Do Herbs Like Deep or Shallow Pots?

Herbs prefer deep pots with proper drainage. Deep containers allow roots to spread and prevent rapid drying.

Shallow containers create inconsistent moisture and stress roots, especially during hot weather.

Growing Herbs Indoors vs Outdoors

Herbs adapt well to both environments, but light is the deciding factor.

Growing Herbs in Pots Indoors

Indoor herbs need strong, consistent light to prevent weak, stretched growth.

Place your planter in a south-facing window where it receives at least 4 to 6 hours of direct sunlight daily. If natural light is limited, supplement with a full-spectrum grow light for 10-12 hours per day.

Low light causes herbs to become leggy, pale, and less flavorful.

Indoor air is often dry, especially in winter. Increase humidity by placing pots on a tray filled with pebbles and water. As the water evaporates, it raises moisture around the plant without soaking the roots.

Rotate containers every few days to promote even growth.

Best indoor performers:

  • Basil
  • Mint
  • Parsley
  • Chives

For a deeper dive into indoor lighting and placement strategies, read Growing Herbs Indoors: Essential Tips.

Growing Herbs in Pots Outdoors

Most culinary herbs need 6 to 8 hours of direct sunlight per day to produce strong growth and concentrated flavor.

Sunlight drives leaf production and the development of essential oils. Herbs grown in insufficient light often become leggy, pale, and less aromatic.

Place containers in the sunniest spot on your patio, balcony, or yard. Rotate pots every few days to ensure even light exposure and balanced growth.

During extreme summer heat, leafy herbs like basil and parsley may benefit from light afternoon shade to reduce stress and prevent wilting.

Perennial herbs that overwinter:

  • Thyme
  • Sage
  • Oregano

Tender annuals:

  • Basil
  • Cilantro

Bring basil and rosemary indoors before the first frost.

For a breakdown of annual versus perennial herbs and how they behave in containers, read Growing Herbs: Annual vs. Perennial Varieties.

Light Rule: Indoors, light intensity drives growth and flavor more than watering does. Outdoors, full sun and heat determine how often containers dry out.

Herb success blueprint with four essential tips for growing herbs in pots.

What Herbs Should Not Be Planted Together?

Herbs should be grouped by water and sunlight needs. Mixing herbs with different moisture requirements leads to root stress, poor growth, and reduced flavor.

Avoid these combinations:

  • Basil with rosemary
  • Parsley with thyme
  • Sage with moisture-loving herbs

These pairings fail because Mediterranean herbs prefer soil that dries between watering, while leafy herbs require steady moisture.

Overwatering rosemary or thyme causes root rot. Underwatering basil or parsley reduces leaf production.

How Often Should You Water Herbs in Pots?

Most potted herbs need water 2 to 3 times per week, or whenever the top inch of soil feels dry.

Containers dry out faster than garden beds because air circulates on all sides of the pot. In hot, sunny, or windy weather, small containers may require daily watering.

Always check the soil before watering. Overwatering is one of the most common causes of root rot in potted herbs.

How to Water Properly

Insert your finger 1 to 2 inches into the soil. If it feels dry, water thoroughly until moisture drains from the bottom.

Avoid light surface watering. Deep watering encourages stronger root growth.

Water in the early morning, when possible, to reduce evaporation and allow roots to absorb moisture before midday heat.

Adjust Watering by Herb Type

Moisture-loving herbs like basil, parsley, and mint prefer consistently moist soil.

Mediterranean herbs like rosemary, thyme, oregano, and sage prefer soil that dries between watering.

Never leave pots sitting in standing water.

“Container gardening success comes down to consistent moisture. Sudden swings from dry to soaked create stress that limits growth.” — Mark Bolt, VP of EarthBox®

Maintaining consistent moisture can be challenging in traditional containers, especially during hot weather or when schedules vary.

Self-Watering Planters Make It Easy

Self-watering planter boxes help regulate moisture by storing water in a reservoir below the soil. Roots draw water upward as needed, which reduces sudden swings between overly dry and overly wet conditions.

For gardeners who struggle with watering consistency, a structured system such as the EarthBox® Herb Garden Kit simplifies moisture management while still providing proper drainage and aeration.

The kit also gets you off to a fast start as it includes:

  • Planter box
  • Aeration screen
  • Water fill tube
  • Mulch/weed cover
  • Peat-based potting mix
  • Dolomite lime
  • Fertilizer

Just pick your herbs, plant, and let the planter box do the rest.

How to Fertilize Herbs in Pots

Less is more.

Excess fertilizer, especially high nitrogen, can dilute essential oils and reduce the strong flavor that herbs are known for.

However, potted herbs benefit from occasional feeding because nutrients wash out of containers over time. Most herbs only need light feeding during active growth.

How Often Should You Fertilize Potted Herbs?

Fertilize every 4 to 6 weeks during spring and summer. Stop feeding in late fall and winter when growth slows.

Use a balanced fertilizer, such as 8-3-5 or 7-7-7.

“With culinary herbs, you’re growing for flavor, not foliage. Overfeeding can make plants look impressive but taste weaker.” — Mark Bolt, VP of EarthBox®

Organic options are ideal for culinary herbs because they support steady growth without overwhelming nitrogen levels. Good choices include:

  • Fish emulsion
  • Kelp or seaweed extract
  • Compost tea
  • Slow-release organic granules mixed into soil at planting

Liquid fertilizers work quickly and are useful after harvesting to encourage regrowth. Always dilute liquid fertilizer to half the label strength to prevent root burn.

Yellowing leaves may indicate nitrogen deficiency. If growth slows significantly during peak season, a light feeding may help.

Fertilizing by Herb Type

Not all herbs require the same nutrient level. Matching fertilizer intensity to plant type protects both growth and flavor.

Light Herb Feeders

  • Rosemary
  • Thyme
  • Oregano
  • Sage

These Mediterranean herbs evolved in lean, rocky soils. Too much fertilizer encourages soft growth and reduces aroma. Feed sparingly.

Moderate Feeders

  • Basil
  • Cilantro

Leafy herbs grow quickly and produce more foliage. They benefit from slightly richer soil and occasional feeding during peak growth.

Rule: Feed leafy herbs lightly but consistently. Feed woody Mediterranean herbs minimally.
