Planting:
Since gherkins cannot survive frost, plant only after all danger of frost has passed and the soil begins to warm. Choose an area with full sunlight, well-drained soil, and away from tree roots. To plant, make 1 inch deep holes spaced 18 inches apart in raised beds down the rows, then plant 3-4 seeds in each hole. Cover seeds with about 1 inch of fine soil and firm the soil with the flat side of a hoe, but do not pack it. Remove extra plants after seedlings emerge.
 
Gherkin vines can reach 6-8 feet long or more and require lots of space. In large gardens, gherkins can be spread on the ground. In small gardens, gherkins can be trained on a fence, trellis, cage, or along a wire attached to a wall. If wire cages are used, plant along the cage or trellis.
