How to care for garlic

  • Light: Requires full sun, at least 6-8 hours of direct sunlight per day, for robust bulb development. Shade can result in smaller cloves.
  • Water: Keep soil consistently moist during the active growth period in spring. Reduce watering significantly as harvest approaches to encourage curing.
  • Soil: Prefers well-draining, loose, rich soil with a pH of 6.0-7.0. Heavy, compacted soils can lead to malformed bulbs.
  • Temperature: Needs a cold period (vernalization) to develop large bulbs, typically planted in fall before the first frost. Grows best at 50-70°F (10-21°C).
  • Humidity: Normal outdoor humidity is suitable. Good air circulation is important to prevent fungal diseases, especially in humid climates.
  • Fertilizer: Incorporate compost into the soil before planting. Fertilize with a balanced nitrogen-rich fertilizer in early spring as growth resumes.
  • Propagation: Propagate by planting individual cloves from a healthy garlic bulb. Each clove will grow into a new bulb.

Is garlic toxic to pets?

Not pet-safe. All parts of the garlic plant are toxic to cats, dogs, and horses, causing damage to red blood cells. See our guide to toxic plants for cats and dogs.

Common problems

  • Yellowing leaves: This can indicate nutrient deficiency, overwatering, or disease; ensure proper fertilization, good drainage, and check for signs of pests or fungi.
  • Small bulbs: Ensure full sun exposure, sufficient water during growth, proper fertilization, and that you planted cloves that were large enough.
