I didn't think that it would work but having searched I found this:-
1. Cut 1/8 inch behind the second set of leaves from the outer tip of the cucumber stem with pruning shears, making the cut straight across the stem in one quick swipe. The stem cutting should be about 3-5 inches long.
2. Pinch off the second set of leaves by hand at the leaf node, just above where the leaf and the stem meet. Keep the first set of leaves intact, because they will help produce roots and supply energy to the new cucumber plant.
3. Dip the cut end of the stem cutting upright into indole-3-butyric acid powered rooting hormone, until the hormone generously covers to just above both leaf nodes from the second set of leaves. Lightly tap the stem cutting on the brim of the hormone container to knock off additional hormone power.
4. Fill a cell starter pack up to the brim with soilless potting mix and insert the cucumber stem cutting upright, about 1/2 inch into the soil, covering the leaf nodes with soil. Place the cell starter pack in a warm location with full to partial sun exposure.
5. Water the cucumber stem cutting daily with a spray bottle set on a fine mist until the soil is completely saturated top to bottom. Keep the soil moist, but not waterlogged. Do not let the soil dry out between waterings. The stem cutting will create a new cucumber plant in about three weeks.
