When to Plant Muskmelons may be directly seeded or started as transplants. If the weather and soil are not warm and the soil moisture level moderate, the seeds do not germinate and the plants do not grow. Plant after the danger of frost has passed and the soil has warmed and dried. Gardeners in northern climates or other short-season areas who want early production may need to use transplants. To increase earliness, start seed for transplants 3 to 4 weeks before planting time. Because muskmelons do not transplant well if the roots are disturbed, you should start seed in individual containers. Proper temperatures for germinating and growing the transplants are very important. Do not allow transplants to become too large before planting in the garden or stunting and crop delays may result. Sterilized media should be used for starting seed to prevent damping-off and other diseases of seeds and seedlings.
