Green Nasturtium Seeds: Wait for Tan Before Planting

Nasturtium seeds collected green in late September (Zone 9b)? Not ready.

Seed Maturity

• Green = immature — won't germinate reliably
• Tan/brown = mature — viable for planting
• Wait for pods to color-change on vine

Planting Timing

Even with mature seeds: Wait until January/February. Nasturtiums need heat (72°F+). Your winters dip lower—cold soil rots seeds or stunts seedlings.

Year-Round Myth

"Year-round in Zone 9b" applies to established plants, not germination. Tropical zones (never below 72°F) are different.

Storage

Mature seeds: Paper envelope, cool/dry, labeled. Plant when soil warms.
