Garlic Growth Guru Quiz Quiz

Explore essential facts about garlic cultivation in horticulture, including planting, care, and harvesting techniques. Sharpen your knowledge of growing healthy, productive garlic crops.

  1. Best Time to Plant Garlic

    When is the most suitable season for planting garlic cloves in most temperate climates?

    1. Spring
    2. Autumn
    3. Mid-winter
    4. Summer

    Explanation: Autumn is generally the best time to plant garlic because it allows the cloves to establish roots before the ground freezes. Summer is too late, as the heat can stress new plants. Spring planting is possible but may lead to smaller bulbs. Mid-winter is often too cold for planting, especially in temperate regions.

  2. Soil Requirement for Garlic

    Which type of soil is most suitable for optimal garlic growth?

    1. Loose, well-drained loam
    2. Soil with standing water
    3. Heavy clay
    4. Rocky soil

    Explanation: Garlic thrives in loose, well-drained loam because it allows proper bulb development and prevents waterlogging. Heavy clay retains too much moisture and restricts root growth. Rocky soil can hinder bulb expansion. Soil with standing water increases the risk of rot and disease.

  3. Correct Planting Depth

    For best growth, how deep should garlic cloves be planted in the soil?

    1. 6–8 inches deep
    2. Over 1 foot deep
    3. About 2–3 inches deep
    4. Just on the surface

    Explanation: Planting garlic cloves about 2–3 inches deep gives them protection and enough soil to develop roots. Surface planting leaves cloves exposed and prone to drying out. 6–8 inches and over 1 foot are excessively deep, limiting sprouting and growth.

  4. Garlic Nutrient Preferences

    Which nutrient is especially important for strong bulb formation in garlic cultivation?

    1. Low nitrogen
    2. Excess sodium
    3. Aluminum
    4. Phosphorus

    Explanation: Phosphorus supports healthy root and bulb formation in garlic. Excess sodium can be harmful to plant growth. While nitrogen is important early on, too much later can reduce bulb size. Aluminum is not considered a necessary nutrient for garlic.

  5. Garlic Harvest Time Indicator

    What is a common visual sign that garlic plants are ready to be harvested?

    1. Bulbs emerge above soil
    2. Plant produces bright blue flowers
    3. All stems remain green and upright
    4. Lower leaves begin to yellow and dry

    Explanation: Garlic is typically ready for harvest when the lower leaves yellow and dry, signifying bulb maturity. Bulbs should stay underground; if they emerge, it may signal overcrowding. Garlic rarely produces bright blue flowers. Stems remaining green and upright indicate the bulbs are not yet mature.
