Yellow crookneck with vibrant color, gourmet flavor, and distinctive ridges and subtle striping. Tempest's 4-7" fruits have a rich, nutty flavor and pleasantly firm texture. Versatile in the kitchen, it retains its shape, texture, and color through a multitude of cooking methods, from grilling and roasting to pickling and braising. Features an open habit and soft spines for easy harvest. We suggest pairing Tempest with Zephyr, another one of Johnny's varieties bred for its unique appearance and superior flavor and texture. NOTE: The presence of the precocious yellow gene causes leaves to express yellow color, which sometimes resembles virus symptoms. This is normal, and the plant should grow and perform as expected. USDA Certified Organic. Avg. 4,500 seeds/lb. Packet: 30 seeds.
SCIENTIFIC NAME: Cucurbita pepo CULTURE: Fertile, well-drained soil with a pH of 5.8–6.8 is best. Plastic mulch and fabric row covers (AG-19 grade) can aide plant establishment and exclude insect pests during the seedling stage. Row covers should be removed when plants begin to flower. Poor fruit development may indicate insufficient pollination. For highest quality fruit, succession plantings every 2-3 weeks may be needed. PLANT SPACING: Space plants 18-24" apart in rows 6' apart. Wider spacing may allow for easier harvesting. DISEASES: Common cucurbit diseases include powdery mildew, downy mildew, bacterial wilt, and phytophthora. Avoid problems with adequate soil drainage, good air flow, insect pest control, and crop rotation. If necessary, check with your local Cooperative Extension Service agent for specific control options. INSECT PESTS: Cucumber beetles, squash bugs, and vine borers are all common pests for cucurbits. Protect young plants with floating row cover. Squash bug eggs found on the undersides of leaves may be crushed by hand. For vine borers, cut out of vines and hill soil over the wound. Keep field borders mowed and remove plant refuse in the fall; spring plow to bury pupae. Pyrethrin sprays may offer some control. HARVEST FRUIT: For some varieties, it is common for the first fruits to be malformed, wither, or blacken, which indicates poor pollination and is usually remedied as more male flowers appear. Harvest regularly, 2-3 times a week, once plants begin to produce. Cut or gently twist off fruits when they have reached the desired size. For summer squash, 4-6". Handle with care to avoid scratching fruits. HARVEST BLOSSOMS: Harvest male blossoms (with thin stems) or female blossoms (with thick stems and an immature fruit at the base of the flower) in mid to late morning when fully open. Clip flowers 1-2" below flower base. If a squash fruit crop is also desired from the same planting, only harvest male flowers, leaving a few to pollinate the female flowers. STORAGE: Keep fruit at 40-50°F (5-10°C), 95% relative humidity for up to 2 weeks. Use as soon as possible for best quality. DAYS TO MATURITY: From direct seeding; subtract about 14 days if transplanting. AVG. DIRECT SEEDING RATE: (at 3 seeds/ft., rows 6' apart) 250 seeds/83', 500 seeds/166', 1,000 seeds/333'. SEED SPECS: SEEDS/LB.: Yellow Summer: Avg. 5,500. PACKET: 30 seeds, (unless otherwise noted) sows 10'.

Days To Maturity
Average number of days from seeding date to harvest, within a specific crop group. If a transplanted crop: average number of days from transplant date. Not sure if crop is direct-seeded or transplanted? Check the Growing Information box for details. If crop can be both direct-seeded or transplanted, days to maturity refers to direct seeding. Days to maturity for all flowers and herbs is calculated from seeding date.
Hybrid: The offspring of a cross between two or more distinct parent lines, usually of same species, and selected for improved traits. Open-pollinated: A non-hybrid variety that can reproduce itself in kind, demonstrating relatively stable traits from one generation to the next.
