This gynoecious cucumber produces predominantly female flowers, which means significantly higher yields compared to traditional varieties. It is also parthenocarpic, meaning it sets fruit without pollination — a huge advantage for greenhouse growing, indoor gardens, low-pollinator areas, or extreme heat conditions when pollination can be unreliable. Natsu features a manageable single-stem growth habit, unlike many Japanese cucumbers that require constant pruning of multiple side shoots, making it easier for home gardeners to maintain. The deep green fruits are slender, crisp, and refreshing with excellent flavor. With strong resistance to powdery mildew and added resistance to target leaf spot and downy mildew, this variety thrives through summer stress while continuing to produce beautiful, high-quality cucumbers.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIdeal Growing Conditions\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSun: \u003c\/strong\u003eFull Sun\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWater: \u003c\/strong\u003eKeep soil consistenly moist but not waterlogged\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFertilizer:\u003c\/strong\u003e Cucumbers benefit from regular fertilizer.

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.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGermination:\u003c\/strong\u003e 7-14 days\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDays To Maturity:\u003c\/strong\u003e 65-75 days after direct sowing the seed\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow \u0026amp; When To Harvest: \u003c\/strong\u003eHarvest when cucumbers are still all green and plump, before they start turning yellow.

It is very common, so dont worry. Spray with 1 cup of hydrogen peroxide per gallon of water to clean and disinfect.
