CULTURE: Watermelons are less tolerant of cool conditions than cantaloupe. They are best adapted to the warmer, longer-season areas of the US. For those gardeners in more difficult climates the use of plastic mulch is essential. Green, silver, or black mulch increases the soil temperature and air temperature close to the plants during the day, and using a floating row cover like Reemay or Gro-Therm can also increase your success. Monitor the temperature under the row covers on hot days especially early in the season. Optimum soil temperature for germination: 70-85°F. Days to emergence: 3-10. Refer to the Melons culture box for specific planting instructions.
INSECTS: Cucumber beetles can sometimes become a problem. Use Rotenone or Rotenone-Pyrethrin for control. Floating row covers make an effective barrier.
DISEASES: Watermelons are subject to several wilts, and fungal and viral diseases. Most can be controlled with good soil management, proper rotation, and garden sanitation.
HARVEST: Watermelons are ready for harvest when the tendril closest to the fruit is dry and brown or when the bottom side of the fruit is yellow. They do not ripen after harvest. Store at 45°F and 85% relative humidity.
SEED SPECS: Minimum germination standard: 80%. Usual seed life: 3 years. Days to maturity: from date of transplanting; add 10-15 days if direct seeding. Approximately 20-40 seeds per gram; 28 grams per ounce.

Sampler: 1 gram
