If you’re looking for a simple and quick way to grow garlic and onions indoors, this guide will show you exactly how to do it.

Why Grow Garlic & Onions Indoors?

Growing garlic and onions indoors has several advantages:

  • Space-saving: Perfect for those with limited outdoor garden space or apartment dwellers.
  • Fresh Produce: You get to harvest fresh garlic and onions right from your kitchen.
  • Health Benefits: Both garlic and onions are rich in nutrients and antioxidants, making them excellent additions to your diet.

Whether you’re growing them for the leaves or the bulbs, both garlic and onions can thrive in indoor conditions with the right care.

How to Grow Garlic Indoors Quickly

Garlic is easy to grow from individual cloves and thrives indoors with enough light and care. Here’s how to do it:

1. Choose the Right Garlic Cloves

  • Select firm, healthy cloves from a garlic bulb. Avoid using grocery store garlic as it may have been treated to prevent sprouting. Instead, use organic garlic that hasn’t been chemically treated.
  • Separate the cloves without damaging the skins.

2. Prepare a Container

  • Choose a container with drainage holes at the bottom to prevent water from accumulating and causing rot. You can use pots, trays, or even old containers like a plastic cup with holes drilled in it.
  • Fill the container with well-draining potting soil. You can also use a mix of potting soil and sand for added drainage.

3. Plant the Garlic Cloves

  • Plant each clove pointy side up, about 2 inches deep in the soil.
  • Space the cloves about 3-4 inches apart to allow them room to grow.
  • Lightly cover with soil and gently pat it down.

4. Provide Light

  • Garlic needs at least 6 hours of direct sunlight each day to grow well indoors. If natural light is limited, consider using a grow light to provide adequate light for the garlic.
  • Place the container in a sunny window or on a windowsill that receives plenty of light.

5. Water Properly

  • Water the garlic gently, keeping the soil moist but not soggy.
  • Avoid overwatering, as garlic bulbs are susceptible to rot in overly wet soil.

6. Harvesting Garlic

  • Garlic takes about 8-10 months to fully mature, but if you’re growing garlic for its leaves, you can start cutting them once the greens have reached about 6 inches tall. Use the leaves in salads, soups, or as a garnish.
  • To harvest the bulbs, wait until the leaves start to yellow and wilt, indicating the garlic is ready.

How to Grow Onions Indoors Quickly

Onions are versatile and easy to grow from sets, seeds, or kitchen scraps. Here’s how to get started:

1. Use Onion Sets or Kitchen Scraps

  • Onion sets (small, immature onions) are the fastest and easiest option for indoor growing. You can also regrow onions from kitchen scraps, like the root ends of a bunch of green onions.
  • If using scraps, place the root ends of the onion in a shallow dish with a bit of water. Green shoots will begin to grow from the top within a few days.

2. Prepare Your Container

  • Choose a container that is at least 6 inches deep to accommodate the onion roots. As with garlic, ensure your container has drainage holes.
  • Use a well-draining potting mix to plant your onions.

3. Plant the Onion Sets or Scraps

  • For onion sets, plant them about 1 inch deep in the soil, spacing them about 2-3 inches apart.
  • If regrowing from scraps, place the onion roots in the water and allow the shoots to grow. You can transplant them into the soil once the roots are well-developed.
  • As the onion grows, you can use scissors to snip the green tops and use them in cooking, similar to green onions.

4. Provide Light

  • Onions need 6-8 hours of direct sunlight each day. Place your container near a sunny window or under a grow light if necessary.
  • Onions need bright, indirect light to grow strong and healthy.

5. Water Regularly

  • Keep the soil moist, but avoid overwatering.
  • Onions have shallow roots, so water them gently to keep the soil from becoming soggy.

6. Harvesting Onions

  • Green onions can be harvested once they reach 6-8 inches tall. Simply cut the green tops with scissors.
  • If you’re growing bulb onions, they will take several months to mature. Once the leaves start to fall over and yellow, your onions are ready to be harvested.

Additional Tips for Growing Garlic and Onions Indoors

  • Temperature: Both garlic and onions prefer cooler temperatures for optimal growth. Keep them in a room with temperatures between 60-75°F (15-24°C).
  • Fertilization: You can feed your plants with a balanced liquid fertilizer every few weeks to encourage stronger growth.
  • Pest Control: While garlic and onions are relatively pest-resistant, always check for any pests like aphids or fungus gnats, especially in indoor environments.

Conclusion

Growing garlic and onions indoors is an easy and fun way to have fresh, homegrown ingredients on hand, no matter the season. By following these simple steps and providing the right conditions, you can enjoy quick growth and even harvest your garlic and onions indoors in no time. Whether you’re growing them for their flavorful greens or bulbs, you’ll appreciate having these nutritious crops right at home. Happy gardening! 🌿🧄🧅
