Crystal Apple cucumbers, a native of New Zealand, are an unusual heirloom variety. The blocky round fruit is white with green lines along its length. The crystal apple variety is sweet and very good for slicing fresh into salads. The growing season is relatively short for a cucumber, with the crop being ready in about 60 days. Crystal Apple loves warmer weather, so wait until the ground has warmed considerably before planting it in your garden.
Dig your cucumber plot in a space that gets at least 6 hours of sun per day. Dig down about 12 inches and remove any roots or rocks that you find. Mix in a 4-inch layer of compost and smooth the surface of the garden bed.
Install your trellis or tomato cage if you haven't dug the bed next to a fence. Cucumbers vine for a long distance, so they need to be trained upright to keep them out of the soil.
Plant your Crystal Apple seeds about 4 weeks after any danger of frost has passed. You can find the average frost date from your local extension service, or in the "Farmers' Almanac."
Plant your cucumber seeds about 6 inches apart. Cucumbers should be planted 1 inch deep. Water the soil until it is saturated.
Thin your Crystal Apple cucumbers to one plant every foot after they are about 6 inches tall. Keep the strongest plants and clip the weaker ones off at the soil line.
Water your cucumbers regularly so that the cucumbers don't become bitter. Place a rain gauge near the cucumbers to find out how much rain they are receiving each week. Add water from a sprinkler to make up any shortfall, bringing the total to 1 inch of water per week.
Pick Crystal Apple cucumbers when they are round and green. When they begin to turn yellow, they are getting past their prime eating time. Pick every 2 or 3 days to encourage the plant to keep producing more cucumbers.
