Heirloom / Open Pollinated Cucumbers are heat loving, frost sensitive vines. Plant heirloom cucumber seeds in full sun, ½ – ¾” deep, in 1′ diameter hills of 4-6 seeds each, 3-4′ apart. Germination occurs in 4-13 days in soil 70-95°F. Thin to 1-2 plants per hill. In short season climates you can start cucumber seeds indoors 3 weeks before last frost, in individual peat pots at least 3½” across. Harden off heirloom cucumbers plants for 1 week before setting out. Harvest regularly for continuous production, making sure to pick overripe cucumbers that were missed. Heirloom slicing cucumbers are best when uniformly green, firm and crisp. For pickles harvest cucumbers when 2-6″ according to preference.
