  • 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.
