Garlic is a staple in kitchens around the world, known for its distinct flavor and numerous health benefits. While many people associate growing garlic with outdoor gardens, it can be just as successfully cultivated indoors. Whether you’re short on garden space, live in an apartment, or want to enjoy fresh garlic year-round, growing it indoors is a rewarding and simple process. In this guide, we’ll walk through the steps to grow garlic indoors, how to care for it, and some tips to get the best results.
Why Grow Garlic Indoors?
Garlic is one of those crops that don’t require much space or intense care. It can thrive in containers and grow successfully indoors as long as it has the right environment. By growing garlic indoors, you can ensure you have a fresh supply of garlic cloves and green garlic shoots (also called garlic scapes) year-round, without worrying about the weather, pests, or limited garden space.
Selecting the Right Garlic for Indoor Growing
Before getting started, it’s essential to choose the right type of garlic for indoor gardening. Garlic generally falls into two categories: hardneck and softneck.
- Hardneck Garlic: This variety is better suited to colder climates and tends to have fewer cloves per bulb. However, hardneck garlic produces garlic scapes—delicious, edible stalks that can be used in cooking.
- Softneck Garlic: Softneck garlic has a longer shelf life, grows well in milder climates, and tends to have more cloves per bulb.
For indoor growing, either variety can work, but softneck garlic is typically easier to find in grocery stores and is often the preferred choice for beginners.
How to Plant Garlic Indoors: Step-by-Step
Growing garlic indoors starts with the planting process. The following steps will guide you through how to properly plant and care for your indoor garlic.
1. Choosing the Right Container
Garlic needs enough space for its roots to grow, so it’s important to choose a container that is at least 6 inches deep. The container should also have good drainage to prevent water from pooling, which can lead to rot. You can use a regular flower pot, a deep planter, or even a plastic container with holes poked in the bottom.
2. Selecting Garlic Cloves
For the best results, use organic garlic cloves from a garden store or your local farmer’s market. Grocery store garlic can sometimes be treated with chemicals to prevent sprouting, which will hinder your indoor growing efforts. Choose large, healthy cloves, as these will produce the biggest and best garlic bulbs.
3. Preparing the Soil
Garlic prefers well-draining soil with a neutral pH level. A mixture of regular potting soil with added compost or organic matter works well. Fill your container with this soil, leaving about an inch of space at the top.
4. Planting Garlic Cloves
To plant garlic, take individual cloves from a garlic bulb. Each clove will become a new garlic plant. Plant the cloves pointy side up, about 2 inches deep into the soil. Space each clove 4-6 inches apart, so they have enough room to grow. If you’re using a small container, you may only be able to plant one or two cloves.
5. Watering Garlic
Water your garlic regularly, keeping the soil moist but not waterlogged. Check the soil every few days by sticking your finger about an inch deep into the soil. If it feels dry, it’s time to water. Garlic likes evenly moist soil, but it’s essential not to overwater to avoid rot.
6. Providing Enough Light
Garlic is a sun-loving plant and requires at least 6 hours of direct sunlight each day. Place your container near a sunny window, preferably one facing south. If you don’t have enough natural light, you can use grow lights to supplement. Keep the lights about 2-4 inches above the plants and adjust them as the garlic grows taller.
7. Fertilizing Garlic
Garlic is not a heavy feeder, but it will benefit from a bit of organic fertilizer every few weeks. You can use a balanced liquid fertilizer or compost tea to provide nutrients that will encourage healthy growth. Be careful not to over-fertilize, as too much nitrogen can lead to lush green growth without developing the garlic bulb.
Caring for Your Indoor Garlic
Once your garlic is planted, the next step is ongoing care. Garlic is a relatively low-maintenance plant, but a few tips will ensure a successful harvest.
1. Temperature and Humidity
Garlic prefers cooler temperatures, ideally around 60-65°F (15-18°C). It can tolerate slightly warmer conditions, but avoid exposing it to temperatures above 80°F (27°C), as this can stress the plant. Indoors, you typically won’t need to worry about humidity, but avoid placing your garlic near heaters or radiators, which can dry out the soil.
2. Managing Pests
Growing garlic indoors usually means fewer pest issues than outdoor gardening. However, indoor plants can still be vulnerable to pests like spider mites, aphids, and fungus gnats. Keep an eye on your plants, and if you notice any pests, treat them with a natural insecticide like neem oil or soapy water.
3. Harvesting Garlic Scapes
Garlic scapes are the long, curly green shoots that emerge from hardneck garlic plants. These scapes are edible and can be harvested before the garlic bulb is ready. To harvest, simply snip them off when they are about 6-8 inches long. They can be used in stir-fries, salads, or as a garnish. Harvesting scapes can also direct the plant’s energy toward developing a larger garlic bulb.
When to Harvest Garlic
Garlic grown indoors will take about 8-10 months to mature fully. You’ll know it’s ready to harvest when the leaves begin to turn yellow and die back. At this point, stop watering the plant to allow the soil to dry out a bit. Carefully dig up the bulbs, being cautious not to damage them.
After harvesting, you’ll want to cure the garlic by leaving it in a warm, dry place for a week or two. This will help the bulbs harden and extend their shelf life.
Growing Garlic Indoors for Year-Round Harvest
The beauty of growing garlic indoors is that you can plant it at any time of the year. With a consistent indoor environment, you don’t have to wait for the right season or worry about the weather. By staggering your planting, you can have garlic growing continuously, ensuring a steady supply of fresh garlic and garlic scapes throughout the year.
Benefits of Growing Garlic Indoors
Growing garlic indoors has several advantages:
- Year-round availability: You can grow garlic regardless of the season.
- Space efficiency: Even small apartments or homes with no yard can produce garlic.
- Pest control: Growing indoors reduces the risk of outdoor pests and diseases.
- Freshness: You’ll have the freshest garlic at your fingertips, with vibrant flavors and full of nutrients.
