Interlaken White Seedless Grape

Interlaken is an early seedless grape with small berries that ripen from green toward golden tones. It is used as a table grape and may also be made into jelly, wine, or raisins. ## In the garden Train its semi-upright growth on a trellis or fence in a sunny location. The [cultivar profile](https://doubleavineyards.com/products/interlaken/) lists USDA zones 5–8 and identifies Interlaken as an early grape. University of Massachusetts Extension describes it as a sister seedling of Himrod that ripens earlier and is useful in cool, short-season areas. ## Growing conditions As a Vitis grape, it is a deciduous climber with small green flowers, as described in the [RHS Vitis profile](https://www.rhs.org.uk/plants/19033/vitis-labrusca/details). Grapes need full sun and well-drained soil. A sandy loam is suitable, and Minnesota Extension recommends watering young vines regularly while established vines generally need irrigation in dry periods. Leave room for shoots and fruiting canes along the support. ## Maintenance Prune annually before spring growth and secure the remaining canes to the trellis.
