My History With Growing Garlic
I first planted garlic as an experiment, taking some leftover store-bought garlic cloves and sticking them in the ground around the weather station we have along one edge of our vegetable garden. To be perfectly honest, I forgot they were there until they began to sprout. Ever since that time, I have always known where to go for garlic if I needed some for a recipe. The garlic cloves are in highest demand during pickle-making season, and I am thankful I have a ready supply. If you are interested in growing your own garlic, here are the best garlic companion plant tips and garlic growing tips I have collected over the years.

Common Questions About Planting and Caring for Garlic
When should garlic be planted?
Garlic is typically planted in the fall, about 4-6 weeks before the ground freezes. In most regions, this means planting garlic between late September and early November. Planting garlic in the fall allows it to establish roots before winter, leading to larger bulbs in the spring and summer. In my Zone 8 garden, planting garlic in September is ideal. If you’re in a warmer climate, you may also plant garlic in early spring, but fall planting generally produces better results.
Where should garlic be planted in the garden?
Plant garlic in well-drained soil with good sunlight exposure. Choose a location with loose, fertile soil, and ensure it receives at least six hours of sunlight daily. Plant garlic cloves about 2 inches deep and 4-6 inches apart, in rows spaced around 12 inches apart. Adequate spacing allows for proper growth and airflow, reducing the risk of diseases. Additionally, avoid areas where water tends to pool, as garlic prefers well-drained soil to prevent rot. In my garden, I have garlic planted around the strawberries and I am considering planting it around the apple trees in our orchard. Here is a photo of some garlic scapes in my garden covered by snow.
What animals does garlic repel?
Garlic is known to repel various animals due to its strong odor and natural compounds. Some of the animals it may deter include:
Deer: Garlic emits a pungent scent that deer find unpleasant, making it an effective deterrent for them. It is one of my favorite deer-resistant plants.
Rabbits: The strong smell of garlic can help keep rabbits away from plants, as they are sensitive to strong odors.
Certain Insects: Garlic is known for repelling certain insects, including aphids, spider mites, and cabbage loopers, among others.
What makes garlic grow faster?
To promote faster growth of garlic, consider the following factors:
Well-Drained Soil: Garlic prefers well-drained soil to prevent waterlogging, which can lead to rot. Loose, friable soil allows for better root development.
Adequate Sunlight: Ensure garlic receives at least six hours of sunlight daily. Adequate sunlight encourages photosynthesis and overall plant vigor.
Proper Planting Depth: Plant garlic cloves about 2 inches deep. Planting at the correct depth allows for optimal root establishment and helps protect against extreme weather conditions.
Appropriate Spacing: Plant garlic cloves 4-6 inches apart in rows spaced around 12 inches apart. Proper spacing provides each bulb with enough room to develop.
Regular Watering: Keep the soil consistently moist, especially during the growing season. However, avoid waterlogged conditions.
Balanced Fertilization: Provide a balanced fertilizer to ensure garlic has the necessary nutrients for growth. Avoid excessive nitrogen, as it may lead to lush foliage at the expense of bulb development.
Why do you soak garlic before planting?
Should you soak garlic before planting? It is frequently recommended that garlic should be soaked before planting, Just separate the cloves and soak in clean water for 12 to 24 hours before planting in well-prepared soal. Soaking garlic cloves before planting serves several purposes:
Stimulates Sprouting: Soaking garlic helps break dormancy and stimulates sprouting. This can lead to quicker and more uniform germination when planted.
Softens Outer Layers: Soaking softens the outer layers of the garlic cloves, making it easier for the emerging shoots to penetrate the soil.
Enhances Root Development: The soaking process can encourage the development of roots. This is particularly beneficial for establishing a strong root system early in the growing process.
Prevents Fungal Diseases: Soaking garlic in a solution that includes fungicides or natural antifungal agents helps reduce the risk of soil-borne diseases, promoting a healthier start for the plant.
What should I add to my soil before planting garlic?
Before planting garlic, enrich your soil with the following amendments:
Compost: Incorporate well-rotted compost to improve soil structure, fertility, and water retention. Compost provides essential organic matter for garlic growth.
Aged Manure: Aged manure, such as well-rotted cow or horse manure, adds nutrients to the soil. Ensure the manure is well-aged to prevent burning the garlic roots.
Bone Meal or Phosphorus Source: Garlic benefits from phosphorus for root development and bulb formation. Adding bone meal or another phosphorus source can support these crucial stages.
Wood Ash or Lime (if needed): Garlic prefers slightly acidic to neutral soil. If your soil is too acidic, consider adding wood ash or lime to adjust the pH.
Organic Fertilizer: A balanced organic fertilizer with a moderate amount of nitrogen can provide the necessary nutrients for garlic growth. Avoid excessive nitrogen, which may result in lush foliage at the expense of bulb development.
Do I peel garlic before planting?
When planting garlic, it’s generally recommended to leave the papery skin on the individual cloves. Plant the entire garlic clove, including the outer layers. The skin acts as a protective layer, helping the garlic clove retain moisture and preventing potential damage during planting.
Separate the cloves from the bulb just before planting, but keep the skins intact. Plant each clove with the pointed end facing up and the flat end down. The skin will naturally decompose as the garlic begins to sprout and grow.
Does garlic like full sun or shade?
Garlic prefers full sun for optimal growth. Planting garlic in a location that receives at least six hours of direct sunlight daily is ideal. Adequate sunlight is crucial for the process of photosynthesis, which is essential for the development of healthy garlic plants and bulbs.
While garlic can tolerate some partial shade, it may result in slower growth and smaller bulbs. To encourage robust growth and maximize bulb development, it’s recommended to plant garlic in a sunny location with well-drained soil.
Can you leave garlic in the ground for 2 years?
It’s not common practice to leave garlic in the ground for two years. Garlic is typically planted annually, and the bulbs are harvested after a single growing season. Leaving garlic in the ground for an extended period may result in the bulbs splitting, deteriorating, or becoming susceptible to diseases.
For best results, harvest garlic bulbs when the tops begin to yellow and fall over, usually in late spring or early summer, depending on the variety. After harvesting, cure the bulbs by drying them in a well-ventilated, shaded area for a few weeks. Once cured, store the garlic in a cool, dry place. Planting fresh cloves each year ensures a consistent and healthy garlic crop.
On a side note, I have left garlic in the ground for longer than a year when I didn‘t harvest the entire garlic crop. The cloves were still usable, but smaller after 2 years.
What is the best fertilizer for garlic?
For garlic, a balanced fertilizer with moderate levels of nitrogen, phosphorus, and potassium is recommended. Consider using an organic fertilizer to provide essential nutrients while promoting soil health. Here are some options:
Compost: Well-rotted compost is an excellent organic option. It not only provides essential nutrients but also improves soil structure and water retention.
Manure: Aged manure, such as well-rotted cow or horse manure, is rich in nutrients. Ensure that the manure is well-aged to avoid burning the garlic roots.
Bone Meal: Bone meal is a good source of phosphorus, which supports root development and bulb formation in garlic.
Organic All-Purpose Fertilizer: Choose an organic, all-purpose fertilizer with a balanced NPK (nitrogen, phosphorus, potassium) ratio. This can provide a well-rounded nutrient profile for garlic.
How much water does garlic need?
Garlic prefers consistent moisture but is susceptible to waterlogging. Here are general guidelines for watering garlic:
Establishment Phase: Keep the soil consistently moist (a watering wand helps) during the initial stages of growth, especially when the garlic is developing roots and shoots. Watering every 3-5 days, depending on weather conditions, is a good starting point.
Bulb Formation Phase: As the garlic bulbs begin to form, reduce the frequency of watering but ensure the soil doesn’t dry out completely. Allow the top few inches of soil to dry between watering. This helps prevent issues like rot and encourages bulb development.
Late Spring to Harvest: In the weeks leading up to harvest (late spring to early summer), reduce watering to allow the soil to dry out slightly. This helps with the curing process and enhances the storage quality of the harvested garlic.
When is the best time to plant garlic?
As with many bulbs, the best time to plant garlic is typically in the fall, a few weeks before the ground freezes. This allows the garlic cloves to establish roots before winter and results in healthier plants the following spring. Planting times may vary based on your location and local climate conditions, but in many regions, planting garlic in late September to November is ideal. Planting in the fall provides the following benefits:
Cold Stratification: Garlic requires a period of cold to break dormancy and stimulate sprouting. Planting in the fall ensures the cloves experience winter chill, promoting robust growth.
Root Development: Fall planting allows garlic to develop a strong root system before the onset of winter, providing a head start for spring growth.
Optimal Bulb Formation: Garlic needs a period of vernalization (exposure to cold temperatures) to produce well-formed bulbs. Fall-planted garlic has an extended period for this process.
Ways to Use Garlic
In addition to being an effective pest repellant (not just for vampires, hee hee), garlic is used in many recipes, such as my favorite quick dill pickles. One little gadget that makes garlic easy to use in recipes is a a premium garlic press that will help you mince garlic with ease. If you aren‘t sure what to do with an abundance of garlic, here is a simple recipe for roasted garlic that can be used in a variety of ways. Roasting garlic brings out its natural sweetness and adds a rich, mellow flavor to various dishes.
Simple Oven Roasted Garlic Recipe
Ingredients:
1 whole head of garlic
Olive oil
Salt and pepper
Instructions:
Preheat your oven to 400°F (200°C).
Peel away the loose, outer layers of the garlic bulb, leaving the cloves still connected.
Trim the top of the garlic head to expose the cloves.
Place the garlic head on a piece of aluminum foil.
Drizzle olive oil over the exposed cloves, ensuring they are well-coated. Sprinkle with a pinch of salt and pepper.
Wrap the garlic in the foil, creating a sealed packet.
Bake in the preheated oven for about 30-40 minutes, or until the cloves are soft and golden brown.
Allow the roasted garlic to cool slightly before handling. Squeeze the cloves out of their skins and use them in recipes, spread on bread, or enjoy as a flavorful addition to dishes.
