Summer raspberries through the year
Against the frost risk in León de los Aldama
Why these dates
Plant bare-root canes while dormant, autumn through late winter. The canes that grow this summer carry next summer's fruit, so anything that damages them - careless pruning most of all - costs a whole season.
Fully hardy. The canes come through hard winters undamaged; it is the spring growth that occasionally catches a late frost, and the plant simply pushes out replacements.
Summer raspberries are planted once and then left in place, so there is no sowing offset to resolve. What matters in León de los Aldama 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.
León de los Aldama sits in zone 10a, which is milder than this crop wants, and a winter that never really arrives is its own problem. The dates below still describe the right time of year; the open question is survival rather than timing.
One caution specific to warm climates: this crop needs roughly 800 hours below 7.2°C (45°F)45°F (7.2°C) over winter before it will flower properly, and the coldest month in León de los Aldama averages 14.1°C (57.4°F)57.4°F (14.1°C). Low-chill varieties exist for exactly this situation and are worth seeking out by name.
Do not expect a crop in the first year. A plant set out now should give its first worthwhile pick around year 2, and will then produce every year after that, which is what makes the planting decision worth getting right the first time.
