Pepper Seeds - Hot - Korean - Beauty Cucumber - Hybrid Start seeds inside 6 weeks before last frost date (or 8 weeks before expected transplanting date). Keep soil warm until emergence. Seeds will not germinate in cool soil and planting out too early may affect plant vigor. Harden off plants carefully before transplanting. Prepare fertile, well-drained soil. Transplant in late spring/summer (soil temperatures at least above 60°F) in a very warm and sunny location. Fertilize as needed. Too much nitrogen will produce lush foliage and few fruits. For fresh eating.
