Description

(Cucumis sativus). The petite 3-inch oval fruit is a bright creamy white, about the size of a small apple. Sweet, mild, and very tender. This variety has become almost extinct in America. Introduced from Australia around 1930 from Arthur Yates and Co., though this type likely originated in China. So tender you can eat it skin and all!

Growing Tips: Crystal Apple cucumber is a unique heirloom variety producing round, white to pale-green fruits resembling small apples with a crisp, sweet flavor. Ideal for fresh eating and pickling, this variety thrives in rich, well-drained soil and full sun. Provide consistent moisture and a trellis or support for best yield and cleaner fruits. Regular harvesting encourages continuous production throughout the season.

When to Grow

Sow Crystal Apple cucumber seeds after the last frost, once soil temperatures remain above 65°F. Warm weather is essential for strong germination and growth. In cooler climates, start seeds indoors 3–4 weeks early and transplant after danger of frost passes.

How to Sow and Plant

Plant seeds 1/2 inch deep in fertile, well-drained soil amended with compost. Space plants 12–18 inches apart in rows or hills spaced 3–4 feet apart. For vertical growth, train vines up a trellis to improve air circulation and fruit quality. Keep soil consistently moist but not waterlogged. Thin seedlings to one or two vigorous plants per hill after true leaves develop.

How to Grow

Maintain even moisture throughout the growing season, watering at the base to prevent leaf diseases. Mulch to retain soil moisture and suppress weeds. Feed with a balanced organic fertilizer or compost tea every few weeks. Harvest cucumbers when they reach 2–3 inches in diameter, while skins are still tender. Frequent picking prolongs the harvest and improves overall fruit quality.

How to Save Seeds

  • Allow several fruits to fully ripen and turn yellow on the vine.
  • Harvest overripe cucumbers and cut open to scoop out the seeds.
  • Place seeds in water for 2–3 days to ferment and remove the gelatinous coating.
  • Rinse thoroughly, dry on a screen or paper towel, and store in a cool, dry place.
  • Label and store seeds in airtight containers; viable for up to five years.
