How to Grow Crystal Apple Cucumber Outside


Crystal Apple cucumbers (Cucumis sativus "Crystal Apple"), native to New Zealand, are round, mild-flavored vegetables. They are easy to grow from seed and provide a novelty crop for children learning to garden. Best eaten while they are small, Crystal Apple cucumbers tend to become bitter as they age on the plant. Plant the Crystal Apple cucumber seeds indoors in late April and they will be ready to plant in the garden in late May or early June, three weeks after the last frost date in your area.

Step 1

Pour compost into a pot and water it until the water drains from the bottom. Allow the pot to drain completely.

Step 2

Push the seed, with the blunt end down, 1/2 inch into the soil and cover it with soil. Keep the soil moist but not soggy.

Step 3

Place the pot in a bright area, on a heat mat set at 75 degrees Fahrenheit. Allow the pot to remain on the heat mat after germination but turn the heat to 70 degrees Fahrenheit when the plant has two sets of leaves.

Step 4

Prepare the outdoor planting area by amending the soil with 3 inches of compost and 3 inches of sand. Mix the amendments into the top 12 inches of soil and rake the area until it is smooth and level.

Step 5

Dig a hole that is the same depth as the germination pot, but twice the diameter. Remove the Crystal Apple cucumber seedling from the pot and place the roots in the hole. Fill the hole with soil and press lightly around the base of the seedling with your hands.

Step 6

Water the Crystal Apple cucumber so that the top 4 inches of soil is moist, and keep the soil moist at all times.

Step 7

Place 3 inches of straw on the soil around the plant for the cucumbers to rest on as they grow.

Step 8

Fertilize the Crystal Apple cucumber plant every two weeks with 1 tablespoon of 33-0-0 fertilizer. Dig a trench, 1 inch deep, 3 inches from the cucumber plant. Pour the fertilizer in the hole and water as you normally do.

Step 9

Pinch back the tips of flowering shoots, to within two leaves of the flower.
