The English telegraph cucumber alias Rollinson's Telegraph alias Telegraph cucumber is an English Heirloom dating back to the 1800s.
It's a big one - the fruits average 12 - 18 inches long. The flesh is crisp and rarely bitter, a mild tasting cucumber with a thin skin and low seed count. Vines yield above average when properly maintained. If permitted to sprawl on the ground the cucumbers are frequently curly and crooked - trellising is required if straight cucumbers are desired.
This variety is commonly grown in greenhouses, is suitable for hydroponics as well as conventional vegetable gardening. A similar variety is English Telegraph Improved, a hybrid variety that produces smaller cukes, but has more disease resistance.
For Direct seeding daytime temps should be above 70 but not much higher than 85 F. Sow at least a week following the last frost. You may need to thin out some of the weaker plants as they begin to develop.
Plant cucumber seeds 1/2 to 1 inch deep and thin the seedlings to one plant every 12 inches in the row or to three cucumber plants every 36 inches in the hill system.
Plant cucumber transplants 1 to 2 feet apart in rows 5 to 6 feet apart when they have two to four true leaves
For greenhouse or Hydroponic Cucumbers it is best to prune to one central leader on each trellis.
