Step by step in Pyongyang
Each window is a range, not a single day. Earlier in the range buys you a longer season; later in it buys you a safer one.
Plant the tree
24 Apr - 22 May
After the last frost, once the soil has warmed. This crop is never fully dormant, so it cannot be planted bare-root in winter.
Harvest
1 Mar - 30 Jun
Macadamias through the year
Against the frost risk in Pyongyang
Why these dates
Young trees are damaged at around -2C. Even a mature macadamia will not tolerate a hard frost, which confines it to genuinely frost-free climates.
Macadamias 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 Pyongyang has passed and the soil has begun to warm, giving the roots the longest possible run before the cold returns.
Pyongyang sits in zone 7a, 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.
Do not expect a crop in the first year. A plant set out now should give its first worthwhile pick around year 5, and will then produce every year after that, which is what makes the planting decision worth getting right the first time.
