Growing garlic indoors can be a bit more challenging than growing it outdoors, but with the right conditions and care, you can enjoy a successful harvest.
Garlic is a cool-season crop, which means it thrives in cooler temperatures and can be grown indoors during the winter months.
With the right conditions, you can grow garlic indoors year-round, providing a constant supply of fresh, delicious garlic for your cooking needs.
Benefits of Growing Garlic Indoors
Growing garlic indoors has several benefits, including:
Year-round harvest
Growing garlic indoors offers the advantage of being able to harvest fresh garlic year-round.
By providing the right conditions such as adequate light, temperature, and moisture levels, indoor gardeners can cultivate garlic bulbs continuously, ensuring a steady supply for culinary use.

Increased Yield
Indoor growing conditions can lead to higher yields compared to outdoor cultivation.
When grown indoors, garlic plants are shielded from external factors that can negatively impact growth and productivity, such as pests, diseases, extreme weather conditions, and fluctuations in soil quality.
Improved flavor
Garlic grown indoors often boasts a more intense and complex flavor profile compared to its outdoor-grown counterparts.
This enhanced flavor is attributed to the controlled environment of indoor gardens, which allows for optimal development of garlic bulbs without exposure to harsh environmental conditions that may compromise taste.
Reduced pests and diseases
Indoor cultivation offers protection against pests and diseases that commonly affect outdoor garlic plants.
By growing garlic indoors, gardeners can minimize the risk of infestations by pests such as aphids, thrips, and nematodes, as well as diseases like white rot, rust, and downy mildew.
Garlic Varieties for Indoors
Not all garlic varieties are suitable for indoor growing. Here are some popular varieties that thrive indoors:
Elephant garlic
Elephant garlic is a popular choice for indoor cultivation due to its large, mild cloves.
Despite its name, elephant garlic is not a true garlic but rather a close relative of the leek.
It produces bulbs with fewer, but larger cloves compared to traditional garlic varieties, making it easier to peel and use in cooking.
Elephant garlic is prized for its mild flavor, which is less pungent than other garlic varieties, making it suitable for those who prefer a milder garlic taste.
Silverskin garlic
Silverskin garlic is another variety well-suited for indoor cultivation.
It is characterized by its mild, sweet flavor and soft, pliable cloves.
Silverskin garlic bulbs typically have a white papery skin and store well, making them ideal for indoor growing where space may be limited.
This variety is often used in culinary applications where a subtle garlic flavor is desired, such as in dressings, sauces, and marinades.
Rocambole garlic
Rocambole garlic is a classic variety prized for its rich, complex flavor and easy-to-peel cloves.
It is well-suited for indoor growing due to its adaptability to controlled environments and its excellent culinary qualities.
Rocambole garlic bulbs typically have a purple-striped outer skin and produce cloves with a full-bodied flavor that is both spicy and sweet.
This variety is often preferred by garlic enthusiasts for its robust taste, which adds depth and complexity to a wide range of dishes.
What You’ll Need
To grow garlic indoors, you’ll need:
- Garlic cloves: Use organic garlic cloves for the best results. Avoid using supermarket garlic, as it may not be suitable for indoor growing.
- Containers: Use pots with drainage holes that are at least 6 inches deep. This will provide enough room for the garlic plants to grow.
- Potting mix: Use a well-draining, loose potting mix that is specifically designed for vegetables.
- Sunlight: Provide bright, indirect sunlight for at least 6 hours daily. A south-facing window is ideal.
- Watering can: Having a watering can with a narrow spout or a spray bottle can facilitate precise watering and prevent overwatering or waterlogging of the soil.
Planting Your Garlic
To plant your garlic, follow these steps:
Chilling the garlic (optional)
If you wish to simulate winter conditions and encourage better bulb development, you can optionally chill the garlic cloves in the refrigerator for a few weeks before planting.
This process, known as vernalization, mimics the cold temperatures experienced during winter and can help stimulate garlic cloves to sprout and grow more vigorously once planted.
Separate the cloves
Before planting, carefully separate the individual cloves from the garlic bulb.
Each clove will grow into a new garlic plant, so ensure that you select healthy, plump cloves free from damage or signs of disease.
Gently twist or peel away the outer layers of the garlic bulb to reveal the individual cloves, being careful not to damage them during the process.
Planting depth and spacing
When planting garlic cloves, ensure they are positioned with the pointed tip facing upwards and the flat basal plate facing downwards.
Plant the cloves approximately 1 inch deep into the potting mix, ensuring they are fully covered with soil.
Space the cloves around 4 inches apart to allow for adequate root development and bulb formation.
Watering after planting
After planting the garlic cloves, water the soil thoroughly to settle it around the cloves and provide essential moisture for germination and root growth.
Use a watering can with a narrow spout or a gentle spray bottle to avoid displacing the soil or disturbing the cloves.
Ensure the soil is evenly moist but not waterlogged, as excessive moisture can lead to rot or fungal diseases.
Garlic Care
To keep your garlic plants healthy and thriving, follow these care tips:
Lighting
Adequate lighting is essential for the healthy growth of garlic plants.
Provide bright, indirect sunlight for at least 6 hours daily to ensure proper photosynthesis and development.
Place your containers near a south-facing window where they can receive ample sunlight throughout the day.
Watering
Proper watering is crucial for the health and vigor of garlic plants.
Water regularly, keeping the soil consistently moist but not waterlogged.
Check the moisture level of the soil regularly by inserting your finger into the soil up to the first knuckle.
If the soil feels dry to the touch, it’s time to water.
Avoid overwatering, as excessive moisture can lead to root rot and other fungal diseases.
Feeding
While garlic plants do not require heavy feeding, optional fertilizing with a balanced fertilizer during the growing season can help promote healthy growth and development.
Choose a fertilizer specifically formulated for vegetables and apply according to the manufacturer’s instructions.
Avoid over-fertilizing, as this can lead to excessive foliage growth at the expense of bulb development.
Harvesting Your Garlic
Here are the signs of maturity and harvesting technique:
Signs of maturity
Determine the optimal time to harvest your garlic by observing the signs of maturity.
Look for yellowing and drying leaves, as well as tops that begin to wither and bend over.
These indicators suggest that the garlic bulbs have reached maturity and are ready for harvest.
Harvesting technique
When harvesting garlic, carefully dig up the entire plant using a garden fork or trowel.
Insert the tool into the soil several inches away from the base of the plant and gently lift the bulbs from the soil.
Take care not to damage the bulbs or disturb the surrounding soil.
Curing garlic
After harvesting, it’s essential to cure the garlic bulbs to preserve them for long-term storage.
Lay the bulbs in a single layer in a cool, well-ventilated area away from direct sunlight.
Allow the bulbs to cure for 2-3 weeks, or until the outer skins become dry and papery.
Once cured, trim the tops to about 1-2 inches and brush off any remaining soil.
