In the temperate zone, container crops are scheduled around the summer solstice when solar energy and temperatures promote rapid growth. Although many container nurseries typically grow one crop per season, some can raise 2 or 3 crops by careful scheduling. The first crop is grown in the greenhouse until outdoor conditions mild enough to move it outside. The second crop is sown just before the summer solstice so the seedling can still benefit from the intense sunlight of early summer, and are left in the greenhouse through the fall.
