SCIENTIFIC NAME

Citrullus lanatus var. lanatus

CULTURE

A light, well-drained soil with a pH of 6.5โ€“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.

TRANSPLANTING

Sow indoors in 50-cell plug trays or 2โ€“3" peat pots in late April or one month (no sooner!) before transplanting outdoors. Plant 2 seeds per cell or pot, about ยฝโ€“1" deep. Keep temperature 80โ€“90ยฐF (27โ€“32ยฐC) until germination. Handle young plants carefully and never let the soil dry out. Grow seedlings at 75ยฐF (24ยฐC). Reduce water and temperature for a week to harden seedlings. When the weather is frost-free, warm, and settled, transplant 2โ€“3' apart in rows 6โ€“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 1โ€“2 weeks after last frost when soil is warm, above 70ยฐF (21ยฐC), 3 seeds every 18โ€“36", ยฝโ€“1" deep, thinning to 1 plant/spot.

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.

ROW COVERS

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).

DISEASES

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.

INSECT PESTS

Protect against cucumber beetles with floating row covers applied at transplanting, or control with insecticides such as pyrethrin or azadarachtin.

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 โ€” you hear "punk," as opposed to "pink" or "pank," when you flick the melon with your fingers.

STORAGE

Hold at 45ยฐF (7ยฐC) and 85% relative humidity 2โ€“3 weeks.

DAYS TO MATURITY

From transplanting; add about 10 days if direct-seeded.
