Against the frost risk in Hohhot
Why these dates
Plant divisions or rooted stems two weeks after the last frost. Harvest whole stems from the outside of the clump from midsummer, cutting at ground level.
Damaged at about 2C and killed by any real frost. Below zone 9 it will not overwinter outdoors, but a pot cut back to 15cm keeps easily in a cool bright room.
Lemongrass are planted once and then left in place, so there is no sowing offset to resolve. Nor is there a dormant season to plant into: this crop keeps its leaves and keeps growing through the winter, which is exactly why cold damages it. The window on this page therefore waits until the last frost in Hohhot has passed and the soil has begun to warm, giving the roots the longest possible run before the cold returns.
Hohhot sits in zone 5a, which is colder than this crop is rated for, so it will need winter protection or a container that can be moved under cover. The dates below still describe the right time of year; the open question is survival rather than timing.
