How to Grow Sultana (grape)

Overview

The Sultana grape, also known as Sultanina or Thompson Seedless, is a popular white grape variety prized for its sweet, juicy flavor and versatility in culinary applications. Native to Asia Minor, these grapes have been cultivated in the regions around İzmir and Manisa in Turkey for centuries.

Growing Conditions

Sultanas thrive in warm climates with long growing seasons. They prefer well-draining soil rich in organic matter and full sun exposure. These vines are vigorous growers, so provide a trellis or support structure to keep them contained.

Planting & Care

Plant Sultana grapevines in early spring after the last frost. Space them about 6-8 feet apart to allow for growth. Water deeply and regularly, especially during dry spells. Apply a balanced fertilizer once a month to encourage healthy growth. Prune annually to maintain vine size and productivity.

Common Problems

Sultana grapes are generally hardy and resistant to many common pests and diseases. However, be on the lookout for aphids, powdery mildew, and grapevine leafroll virus. If issues arise, use organic methods like neem oil or sulfur for pest control, and remove affected leaves or vines.

Harvest or Enjoy

Harvest Sultanas when they reach peak ripeness in late summer to early fall. They will be slightly yellow and easily release from the vine when gently twisted. Enjoy fresh off the vine, or use them in jams, raisin production, or winemaking. Store extras in a cool, dry place for future enjoyment.
