Triploid (seedless) watermelon can be tricky to germinate, so we recommend starting seed indoors and keeping the soil temperature at 85-90 degrees F until germination occurs. Note: Triploids require planting with a diploid pollinator in a ratio of three triploids to one diploid. When purchasing seed packets, Harvest Moon will be packaged with the proper number of pollinators. When purchasing transplants at retail, please inquire which pollinator is best to interplant with Harvest Moon to ensure success.

Sow seed 4 weeks prior to last frost date. Sow seed directly into peat pots filled with a soilless mix that has been well-watered and allowed to drain. Cover with media and maintain 85-90 degrees F. Wrap in plastic to maintain uniform moisture. Keep warm, transplant after soil and air temperatures warm or protect from cool night temperatures.
