Asiatic lilies through the year
Against the frost risk in Zhu Cheng City
Why these dates
Plant while dormant, in autumn or as soon as bulbs appear in late winter, and plant deep - three times the height of the bulb, around 18cm - because the stem roots as well as the base. Never let the bulbs sit dry on a shelf; plant them the week they arrive.
Hardy to about -30C and unbothered by frost on the emerging shoot. The real hazard is winter wet on heavy ground, which rots the scales; a handful of grit under each bulb solves it.
Asiatic lilies are planted once and then left in place, so there is no sowing offset to resolve. What matters in Zhu Cheng City is the shape of the year: this crop is dormant through the winter and is planted while it sleeps, any time between leaf fall in autumn and the restart of growth in spring, so long as the ground is neither frozen nor waterlogged. That is why the window below spans the cold months rather than sitting in the middle of the growing season.
Hardiness is not the obstacle here. Zhu Cheng City is zone 7b, comfortably inside the range this crop is rated for, so an established plant should come through an average winter without protection.
