ToxicityTo humans
While garlic is generally safe and widely consumed as a food ingredient, excessive consumption of raw or concentrated garlic can have adverse effects on some individuals. In rare cases, consuming large amounts of garlic can cause gastrointestinal distress, such as stomach upset, nausea, and diarrhea. Additionally, some people may experience allergic reactions to garlic, which can range from mild skin irritation to severe respiratory symptoms. It is always advisable to consume garlic in moderation and consult a healthcare professional if you have any concerns or underlying health conditions.
To pets
Garlic, particularly in large amounts, can be toxic to certain animals. Dogs, cats, and some livestock species, such as horses and cattle, are particularly susceptible to garlic toxicity. Garlic contains compounds called thiosulfates, which can cause oxidative damage to red blood cells in these animals, leading to a condition called Heinz body anemia. Symptoms of garlic toxicity in animals may include weakness, pale gums, increased heart rate, and in severe cases, collapse or even death. It is crucial to keep garlic and garlic-containing foods away from pets and livestock to prevent potential harm.

WaterGarlic typically requires moderate watering. It's important to keep the soil evenly moist but not waterlogged.
During the growing season, which is usually spring and early summer, water the garlic plants once a week or whenever the top inch of soil feels dry. Reduce watering as the garlic plants approach maturity to allow the bulbs to dry out and cure.
LightGarlic prefers full sun exposure for optimal growth. It thrives in bright, direct sunlight, ideally receiving 6 to 8 hours of sunlight each day. Adequate sunlight helps promote healthy leaf growth and bulb development.
TemperatureGarlic is a cool-season crop that prefers moderate temperatures. It grows best in temperatures between 55°F (13°C) and 77°F (25°C). Garlic can tolerate colder temperatures, even surviving frost, but extreme heat can negatively impact its growth. High temperatures above 90°F (32°C) can inhibit bulb formation and reduce the overall quality of the harvest.
PruningGarlic doesn't require extensive pruning.
CleaningNot needed
SoilGarlic thrives in loamy or sandy soil that allows for good drainage. Avoid heavy clay soils that can become waterlogged and lead to rot.
Incorporating organic matter, such as compost or well-rotted manure, into the soil before planting helps improve soil structure, fertility, and moisture retention.
Garlic prefers a slightly acidic to neutral soil pH in the range of 6.0 to 7.5. Conduct a soil test to determine the pH level of your soil and make adjustments if needed by adding lime to raise pH or sulfur to lower pH.
RepottingGarlic is typically not repotted like container plants.
Humidity & MistingGarlic is generally adaptable to various humidity levels but prefers moderate humidity. It can tolerate a range of humidity, from drier conditions to slightly more humid environments. However, high humidity can increase the risk of fungal diseases, such as bulb rot, so it's important to ensure good air circulation and avoid excessive moisture around the garlic plants.

Life cyclePlanting (Months: October - November or April - May): Winter garlic is planted in the fall, several weeks before the ground freezes. The exact timing can vary based on the region. The cloves are separated from the bulb and planted with the pointed end facing up, about 2 inches deep in well-prepared soil.
Regular garlic is planted in April to May, when the soil is warm enough.
Germination and Early Growth (Months: November to December): After planting, garlic cloves go through a period of dormancy. In cooler climates, the cloves may begin to sprout before going dormant for the winter. During this stage, the garlic establishes its root system and prepares for growth in the following spring.
Vegetative Growth (Months: March to May): As the weather warms up in spring, garlic starts to emerge from the soil. The growth of green shoots and leaves is a sign that the garlic is actively growing. During this stage, the garlic plants focus on developing foliage and capturing sunlight for energy through photosynthesis.
Bulb Formation (Months: May to June): As the garlic plants continue to grow, they start forming bulbs underground. The bulb formation stage is crucial for garlic cultivation. Adequate sunlight, proper soil moisture, and nutrients are important during this period to support the development of healthy bulbs.
Flowering (Months: June to July): Garlic plants produce flower stalks called scapes. Scapes emerge from the center of the plant and coil as they grow taller. These scapes can be removed to divert energy towards bulb growth, as mentioned earlier.
Maturation and Harvest (Months: June to August): The final stage of garlic's life cycle is maturation and harvest. The timing for harvest can vary depending on the desired maturity of the bulbs. Typically, garlic is harvested when the foliage starts to turn yellow and dry out. This usually occurs in mid to late summer. Harvested garlic bulbs are then dried and cured before storage or consumption.

Clove Selection: Choose healthy, large garlic bulbs for propagation. Separate the cloves from the bulb, ensuring each clove is intact and free from damage or disease.
Planting Time: Garlic cloves are typically planted in the fall, a few weeks before the ground freezes. The exact timing can vary based on the region and the desired harvest time. In general, garlic is planted between October and November in many areas.
Clove Planting: Plant the garlic cloves with the pointed end facing up and the basal plate (the flat end where the clove was attached to the bulb) facing down. Plant them about 2 inches deep and space them 6 to 8 inches apart in rows. Ensure good soil drainage and provide adequate sunlight.
Overwintering: Once planted, garlic cloves will go through a period of dormancy during the winter months. The cloves establish roots and remain dormant until spring.
Spring Growth: As temperatures warm up in spring, the garlic cloves start to sprout and emerge from the soil. Green shoots and leaves develop, and the garlic plants enter their vegetative growth stage.
