When to plant walnuts in Perm

Why these dates

Plant dormant. Walnut leafs out late, which conveniently protects it from spring frost, but the nuts then need a long warm autumn to fill. Grafted named varieties bear years earlier than a seedling and are worth the extra cost.

The dormant tree is hardy to about -25C. The late leafing means frost damage to new growth is rare, which is unusual among nut trees.

Walnuts are planted once and then left in place, so there is no sowing offset to resolve. What matters in Perm 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.

Perm sits in zone 3a, 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 6, and will then produce every year after that, which is what makes the planting decision worth getting right the first time.
