FAQ
When should I start green bean indoors?
Green Bean is usually not worth starting indoors; outdoor sowing is more practical.
Can I sow green bean outdoors?
Green Bean can be sown outdoors when soil and nights are suitable. In California, the spring estimate is about March to April.
When should I transplant green bean?
Green Bean is not usually transplanted because root disturbance can hurt establishment.
How long does green bean take to harvest?
Green Bean is listed at about 55 days to maturity. Cool weather, weak light, or stress can extend that timeline.

Yes. Bush beans work in medium containers; pole beans need support.
What is the most common green bean mistake?
Starting too early in cold, wet soil.
Is green bean better in spring or fall?
Spring is usually safer; fall planting needs enough warm days before first frost.
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.
