FAQ
When should I start garlic indoors?
Garlic is usually not worth starting indoors; outdoor sowing is more practical.
Can I sow garlic outdoors?
Garlic can be sown outdoors when soil and nights are suitable. In California, the spring estimate is about October to November.
When should I transplant garlic?
Garlic is not usually transplanted because root disturbance can hurt establishment.
How long does garlic take to harvest?
Garlic is listed at about 240 days to maturity. Cool weather, weak light, or stress can extend that timeline.
Is garlic container friendly?
Yes. Use deep containers with excellent drainage.
What is the most common garlic mistake?
Planting grocery garlic that is not adapted to local conditions.
Is garlic better in spring or fall?
Both spring and fall can work in many states, but fall timing should count backward from the first frost date.
Is this ZIP-code accurate?
No. V1 uses conservative state-level windows and reserves ZIP-code frost dates, USDA zone matching, and reminders for the next phase.
