Garlic is a kitchen essential, and growing it indoors ensures you always have a fresh supply within reach. Even if you don’t have outdoor space, you can still cultivate this flavorful crop in containers on a windowsill, balcony, or well-lit corner. Growing garlic indoors is simple, rewarding, and requires minimal equipment. Here’s a detailed guide on how to successfully grow garlic in containers inside your home.

Choosing the Right Garlic

The first step is to choose the right type of garlic for indoor cultivation. There are two main types:

  • Softneck Garlic – Best suited for indoor growing because it stores well and doesn’t need cold exposure. This type also has a flexible stalk and produces more cloves per bulb.

  • Hardneck Garlic – Typically grows better outdoors in cooler climates but can still work indoors with the right care.

Buy organic garlic from a nursery or garden center rather than supermarket garlic, which may be treated to prevent sprouting.

Selecting a Container

Garlic needs space to develop healthy bulbs and roots. Choose a container with the following features:

  • Depth: At least 6 inches (15 cm) deep

  • Width: Depending on how many cloves you want to plant, choose a pot that offers 4-5 inches (10-13 cm) of space between cloves

  • Drainage: Make sure the pot has holes at the bottom to prevent waterlogging

You can use clay, plastic, ceramic, or even fabric grow bags—just ensure proper drainage and airflow.

Preparing the Soil

Garlic thrives in loose, well-draining soil rich in organic matter. For indoor growing:

  • Use a high-quality potting mix that retains moisture without becoming soggy

  • Mix in compost or well-rotted manure to provide nutrients

  • Add perlite or sand to improve drainage if the mix is too heavy

The soil pH should be slightly acidic to neutral, ideally between 6.0 and 7.0.

Planting Garlic Cloves

Once you’ve prepared the container and soil, it’s time to plant:

  1. Separate the Bulb – Break the garlic bulb into individual cloves. Choose the largest, healthiest ones for planting and leave the papery skins intact.

  2. Plant the Cloves – Insert each clove pointed-end up, about 2 inches (5 cm) deep into the soil. Space them 4-5 inches (10-13 cm) apart.

  3. Water Lightly – Water the soil gently after planting to help the cloves settle in.

Place the container in a location that receives at least 6 hours of direct sunlight daily—a south-facing windowsill is ideal. If natural light is limited, use a grow light to supplement.

Watering and Maintenance

Garlic doesn’t like overly wet soil, so careful watering is essential:

  • Water when the top inch of soil is dry—usually once or twice a week, depending on indoor conditions.

  • Avoid waterlogging, which can lead to root rot.

  • Keep the area well-ventilated to reduce the risk of fungal diseases.

As the garlic grows, you’ll notice long green shoots, known as garlic greens or scapes. These are edible and can be trimmed for use in cooking. Cutting the scapes also helps the plant focus energy on bulb development.

Feeding the Plants

Garlic is a light feeder but benefits from occasional fertilization:

  • Apply a balanced liquid fertilizer every 3-4 weeks during the growing period.

  • For organic options, use diluted fish emulsion or seaweed extract.

Stop fertilizing once the leaves begin to yellow—this signals the bulbs are nearing maturity.

Harvesting Garlic Indoors

Garlic typically takes 8 to 10 months to fully mature, even indoors. However, you can harvest garlic greens much earlier—within a few weeks of planting.

For full bulbs:

  • Watch for the lower leaves to turn yellow or brown while the upper leaves remain green.

  • Gently loosen the soil and lift the bulbs with your hands or a small tool.

  • Let the bulbs cure in a dry, warm, well-ventilated area for 1-2 weeks before storing.

Once cured, store your garlic bulbs in a cool, dry place away from direct sunlight.

Bonus Tip: Regrow Garlic from Scraps

If you’ve already used some garlic in the kitchen, don’t toss those sprouting cloves! You can plant garlic scraps with green shoots into a container and grow them for greens or even small bulbs over time.

Final Thoughts

Growing garlic indoors in containers is not only convenient but also a great way to enjoy organic, fresh garlic year-round. With a bit of care, attention to light and watering, and a well-prepared container setup, you can harvest flavorful garlic even from a small apartment or indoor space. Whether you grow it for the greens or wait for full bulbs, indoor garlic is a satisfying addition to your indoor garden.
