Start seeds indoors six weeks before last frost date. Seed saved from this hybrid variety is not likely to grow true to the parent plant.
Look to ensure a distance 3.44 feet (1.06 metres) between seeds when sowing - bury at a depth of at least 0.25 inches (0.64 cm) deep. Soil temperature should be kept higher than 18°C / 64°F to ensure good germination.By our calculations, you should look at sowing Endless Summer about 42 days before your last frost date.
Before transplanting, move to a sheltered area outside for a week.
Plant to the first set of true leaves to promote strong root growth.
Ensure that temperatures are mild (minimum night temperatures should be around 18°C / 64°F) and all chance of frost has passed before planting out, as Endless Summer is a tender plant.
