This lemongrass is adapted to hot wet summers and dry warm winters., it is drought tolerant and will grow on a wide range of soils although it prefers rich and moist loams. It cannot stand wet feet and if it is damaged by frost in cooler areas, the tops should not be cut until all danger of frost has passed.1
Ensure that temperatures are mild and all chance of frost has passed before planting out, as East Indian is a tender plant.Malabar grass
