Days To Maturity
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 Status
Hybrid Status
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. -
Hybrid (F1)
Onza (F1) Watermelon Seed
New! Personal-sized and powdery mildew resistant.
Onza is strong from the start, with good germination and seedling vigor that leads to long, vigorous vines at maturity. A bit later to mature than Ocelot, but worth the wait. Its striking dark red flesh is firm, juicy, and sweet. Tiger-striped rind and globe-shaped, 3–5 lb. fruits. Avg. 1–2 fruits/plant.Disease Resistance:

SCIENTIFIC NAME:
Citrullus lanatus var. lanatusCULTURE:
A light, well-drained soil with a pH of 6.5–7.5 and a southern exposure is ideal. Good soil moisture is important in early stages of growth and during pollination when fruits are setting. After this point do not water the last week before fruits are ripe, as overwatering can cause bland fruit. Since watermelons like consistently warm conditions, plastic mulch and row covers will make for earlier crops and better yields, especially in the North. Remove covers when plants have female flowers (tiny fruit at base of blossom).DAYS TO MATURITY:
From transplanting; add about 10 days if direct-seeded.TRANSPLANTING:
Sow indoors in 50-cell plug trays or 2–3" peat pots in late April or one month (no sooner!) before transplanting outdoors. Plant 2 seeds per cell or pot, about ½–1" deep. Keep temperature 80–90°F (27–32°C) until germination. Handle young plants carefully and never let the soil dry out. Grow seedlings at 75°F (24°C). Reduce water and temperature for a week to harden seedlings. When the weather is frost-free, warm, and settled, transplant 2–3' apart in rows 6–8' apart, or thin to 1 plant/pot or cell with scissors and transplant 18" apart. Even hardened watermelon seedlings are tender! Do not disturb roots when transplanting, and water thoroughly.DIRECT SEEDING:
Sow 1–2 weeks after last frost when soil is warm, above 70°F (21°C), 3 seeds every 18–36", ½–1" deep, thinning to 1 plant/spot.AVG. DIRECT SEEDING RATE:
1 oz./340', 1,000 seeds/500', 3 oz./1,000', 1⅓ lb./acre at 3 seeds every 18", in rows 6' apart.TRIPLOID/SEEDLESS:
Start indoors under favorable conditions to ensure proper germination. A pollenizer watermelon, or normal seeded watermelon, is required for fruit set. Seeds of a pollenizer and complete growing instructions are included with each order. Although the fruits are practically seedless, a few seeds may form under stressful conditions. For more information, see our Seedless Watermelon production guide.INSECT PESTS:
Protect against cucumber beetles with floating row covers applied at transplanting, or control with insecticides such as pyrethrin or azadarachtin.DISEASE:
Choose varieties resistant to diseases in your area. "Sudden wilt" is a complex disease and cold weather stress syndrome in late summer when plants have a heavy set of ripening watermelons, can cause plants to wilt almost overnight. Keep plants healthy with good fertility and irrigation to avoid sudden wilt.RIPENESS:
There are 3 ways to tell when a watermelon is ripe: 1) the tendril nearest the point on the vine where fruit stem attaches is browning/dead; 2) the spot where the fruit rests on the ground is yellow; and 3) the classic mystery — you hear "punk," as opposed to "pink" or "pank," when you flick the melon with your fingers.STORAGE:
Hold at 45°F (7°C) and 85% relative humidity 2–3 weeks.TRANSPLANTS:
