Japanese Long Cucumber Seeds

Japanese Long Cucumber Seeds – Long, Thin & Crisp Asian Cucumber
Cucumis sativus
Listing is for 1 packet of minimum 15 seeds

Japanese Long cucumbers are a prized heirloom variety known for their slender, straight shape and crisp, nearly seedless texture. These cucumbers grow up to 12–18 inches long and have thin, dark green skin that doesn’t require peeling, making them perfect for fresh eating, slicing, pickling, or adding to salads. Their mild, slightly sweet flavor and crunchy bite make them a favorite in both home gardens and gourmet kitchens. Japanese Long cucumbers grow best with support—trellising helps keep the fruit straight and clean—and they produce abundantly in warm, sunny weather. This variety is a must-grow if you're looking for a high-yielding, delicious, and elegant cucumber that stands out in the garden.

Ideal Growing Conditions

Sun: Full Sun

Water: Keep soil consistenly moist but not waterlogged

Fertilizer: Cucumbers benefit from regular fertilizer. Use an all purpose organic granular fertilizer like Espoma Garden Tone, so you can fertilize in small amounts, about 1/4 cup every 7 to 10 days. You can easily burn plants if fertilizing this often with a synthetic fertilizer, thus why I recommend organic. Keeping nutrients consistent, makes the plant grow lots of new healthy green growth to outpace all the growth that is catching diseases.

When & How To Sow Seeds: For a spring crop: direct sow seeds after your last spring frost date. For a fall crop: direct sow seeds at the end of summer. Use square foot gardening guidelines to grow 2 cucumber plants per square foot. Or dig a shallow trench right under a vertical trellis structure, sprinkle in the seeds, and cover with about 1/2 inch of soil. You can sow cucumber seeds pretty densely. Keep the soil moist for better germination. If you have multiple rows, space them with 3-4FT in-between for better airflow. Or you can sow seeds indoors, 6-8 weeks before your target date of transplanting into the garden. Use a 4inch pot or a solo cup with holes cut out of the bottom for drainage. Fill with seed starting mix. Sow 2-3 seeds per container.

Germination: 7-14 days

Days To Maturity: 65-75 days after direct sowing the seed

How & When To Harvest: Harvest when cucumbers are still all green and plump, before they start turning yellow. Try to harvest before the cucumbers get over 8-10 inches long for the best flavor and texture. 

Common Diseases: Cucumbers get a lot of leaf diseases caused by pathogens like molds, fungus spores, bacteria etc.... It is very common, so dont worry. Spray with 1 cup of hydrogen peroxide per gallon of water to clean and disinfect. Repeat every 5 days or so as a preventative, or until you notice the spread of the disease has stopped. 

Common Pests: Critters like rabbits love to munch on newly germinated seedlings, so protection from small animals might be required. If you notice the leaves are chewed up and there are small black, green, or orange balls, worms/caterpillars are chewing up the plants. Spray with BT or spinosad to treat for the worms.
