When to Plant Beets in Hawaii
Two crops in one — eat the roots and the greens. Beets are cold-hardy and surprisingly easy.
The Short Answer
Hawaii Frost Dates
Your planting dates depend on which part of Hawaii you're in. Here are the frost date ranges by region:
| Region | Zones | Last Frost (Spring) | First Frost (Fall) |
|---|---|---|---|
| Coastal Hawaii | 11a, 11b, 12a, 12b, 13a | None | None |
| Upcountry/Mountain | 10a, 10b, 11a | Rare | Rare |
Beets Planting Schedule for Hawaii
Coastal Hawaii (Zones 11a, 11b, 12a, 12b, 13a)
Average last frost: None · Average first frost: None
Upcountry/Mountain (Zones 10a, 10b, 11a)
Average last frost: Rare · Average first frost: Rare
Growing Beets in Hawaii
Beets in Hawaii's Climate
Grow beets from October through January. The window is short but productive. Sandy subtropical soils grow beets with compost for nutrients. Heat causes tough, woody roots — don't attempt summer production.
Soil Considerations for Hawaii
Volcanic soils — extremely fertile but can be acidic. Excellent drainage on slopes. Varies dramatically by island and elevation. Loose, well-drained soil is especially important for beets since the edible portion grows underground. If your soil is heavy clay, consider raised beds.
Hawaii Climate & Growing Season
Tropical. Year-round growing season at lower elevations. Elevation creates microclimates. Plant warm-season crops anytime. Beets can handle frost well, which is an advantage in Hawaii's climate. You can push planting dates earlier in spring and extend into fall.
Growing season length varies across Hawaii: Coastal Hawaii (11a, 11b, 12a, 12b, 13a) has a last frost around None, while Upcountry/Mountain (10a, 10b, 11a) sees frost end around Rare. This difference matters for beets — but beets handle frost well, so the timing difference is less critical.
Growing Tips
Each beet 'seed' is actually a cluster — thin to one plant after sprouting. Harvest at 1.5-3 inches for tender roots.
Companion Planting
Plant beets alongside these companions for better growth:
