‘Telegraph Improved’ is a refined English heirloom cucumber prized for its extra-long, slender fruits, smooth glossy skin, and crisp, refreshing flavor. An improved strain of the classic 1800s ‘Telegraph’ cucumber, it produces burpless, bitter-free fruits with very small, soft seeds and a firm texture that holds well after harvest.

Start ‘Telegraph Improved’ indoors for transplanting or sow directly in the garden about ½ inch deep. Space plants 12 to 18 inches apart and grow in full sun. This heat-tolerant variety performs well in both outdoor gardens and greenhouse production and benefits from trellising to support its vigorous vines and encourage straighter fruits.

Ready to harvest in about 65 days, begin picking the fruits once they reach a usable size while they are still firm, crisp, and tender. Harvest regularly to encourage continued production and maintain the best texture and flavor.

Mild, crisp, and refreshing, ‘Telegraph Improved’ is excellent for fresh eating, slicing, salads, sandwiches, snacking, and market production.
