Frequently Asked Questions
Late winter (January-February) offers the best selection as seed companies release new inventory. Early spring (March-April) still has good availability. Buy 4-8 weeks before your planned planting date.
For most home gardeners, conventional seeds work perfectly fine. The resulting plant is identical. Choose organic if you're pursuing certification, want untreated seeds, or prefer supporting organic agriculture.
Start with a single packet (15-25 seeds). This provides enough for 4-6 plants with backup seeds. Don't buy bulk until you've confirmed you can grow loofahs successfully.
Technically yes, but success rates are low (20-40% germination). Commercial loofahs are often harvested before seeds mature, and processing may damage viability. Purchase fresh seeds for reliable results.
