Right plant, right place

Will Interlaken grape grow at your Arizona property?

A hybrid of Thompson Seedless and an American grape. Its cold tolerance makes it a compelling choice outside the hottest urban core, while low-desert growers should prioritize airflow and cluster shade.

Best regional fit: Valley suburbs · USDA 9a–9b, Desert outskirts · USDA 8b–9b, High desert · USDA 6a–8b.

Planting & stewardship

How to help Interlaken grape thrive

  1. 1

    Install a sturdy trellis and train a permanent trunk and cordons.

  2. 2

    Use an annual dormant-pruning system suited to the fruiting wood.

  3. 3

    Thin congested shoots to improve airflow without exposing fruit to harsh sun.

  4. 4

    Harvest when berries are fully sweet because grapes do not continue ripening after picking.
