## Questions & Answers

**Q: How long are the seeds good for?**
A: Seeds are best if used promptly, but lettuce seeds generally remain viable for 2-3 years and we use premium packaging to keep moisture from ruining your seeds and extend their viability.

**Q: What conditions will these seeds grow in?**
A: Lettuce thrives in cool temperatures, ideally between 60-70°F. It requires well-drained, fertile soil with a neutral pH and consistent moisture. Full sun to partial shade is best for growth. Protecting it from extreme heat and frost is important.

**Q: Will lettuce grow in warmer temperatures?**
A: Lettuce seeds can go dormant above 75° to protect themselves from poor growing conditions. Those same temperatures can also cause already grown plants to "bolt", causing the plant to shoot up and leaves to grow bitter.

**Q: What is the germination rate of these seeds?**
A: While germination rates vary from lot to lot, almost all lots will have a germination rate of 85% or higher.

**Q: How long from planting the seeds to harvesting lettuce?**
A: Buttercrunch will be fully grown in 55-70 days, but can be harvested after about 30 days for baby greens.
