Protect from occasional frost between November 15 and May 1. Temperatures are listed for optimal germination rates and transplanting. Seeds may germinate outside range but can be subject to rotting in cool temperatures unless chemically treated. Use heat-tolerant, bolt-resistant varieties for winter and spring planting. These will last even into summer. Sources for heat-tolerant and bolt-resistant seeds: Native Seed Search Johnny's Selected Seeds** † Naturally bolt-resistant.
