It grows up to 60 cm in height and produces an underground bulb that is divided into cloves.

Taxonomic Information

Appearance

Garlic has long, flat leaves that emerge from the base of the plant. The leaves can grow up to 30 cm in length and are gray-green in color. The plant produces a tall stalk that terminates in a spherical inflorescence, which contains numerous small white or pink flowers. The underground bulb is composed of several individual cloves that are covered in a thin, papery skin. The cloves are white in color and have a characteristic pungent odor and taste.

Care Guide

Garlic is a low maintenance plant that requires minimal care. Here are some tips for growing healthy garlic:

• Water: Garlic requires regular watering, especially during the growing season. Water the plants deeply once a week, or more frequently if the soil is dry.
• Fertilization: Garlic benefits from an application of compost or well-rotted manure before planting. Avoid using nitrogen-rich fertilizers, as they may promote excessive vegetative growth at the expense of bulb development.
• Soil: Garlic prefers well-drained, fertile soil that is rich in organic matter. The soil should have a pH between 6.0 and 7.0.
• Sunlight: Garlic requires full sun to grow and produce healthy bulbs. Plant the cloves in an area that receives at least 6 hours of sunlight per day.
• Hardiness Zones: Garlic is a cold-hardy plant that can be grown in USDA zones 3-9.

Common Pests & Diseases

Garlic is generally resistant to pests and diseases, but there are a few common issues that may arise:

• White Rot: This fungal disease can cause the bulbs to rot and turn yellow. It is most common in wet, humid conditions.
• Onion Thrips: These small insects can damage the leaves and bulbs of garlic plants. They are most common in hot, dry weather.
• Nematodes: These microscopic worms can damage the roots of garlic plants, leading to stunted growth and poor bulb development.
• Garlic Rust: This fungal disease causes yellow or white spots on the leaves, which eventually turn brown and die. It is most common in humid conditions.

Habitat

Garlic is a versatile plant that can be grown in a variety of conditions. It prefers cool, dry climates with well-drained soil and full sun. Garlic can be grown in garden beds, raised beds, or containers. It is also well-suited for companion planting with other vegetables, such as tomatoes, peppers, and lettuce.
