Look to ensure a distance 1.62 feet (50.0 cm) between seeds when sowing - bury at a depth of at least 0.39 inches (1.0 cm) deep. Soil temperature should be kept higher than 12°C / 54°F to ensure good germination.Plant to first leaves to promote strong roots.
Ensure that temperatures are mild and all chance of frost has passed before planting out, as Grub's Mystery Green is a tender plant.David “Grub” Lockwood found this plant in Australia in 2005. The plant he found was regular leaf, but later plantings were potato leaf.1
