Two genetically distinct trees are needed for fruit set. With proper care, seed grown pawpaw's will fruit in 5-8 years. Provide seedlings with dappled sunlight, full sun will scorch the leaves of 1st year seedlings. Once the tap root radical emerges, the sprouted seed be planted in a pot as described above. Place this bag in warm location (75o- 85o F), out of direct sunlight. Stratified seeds can also be wrapped in piece of damp paper towel and placed in a zip-lock bag. The seed will normally germinate in 2-3 weeks, and the shoot will emerge in 2 weeks to 2 months. Sow seeds in tall containers, with a height of about 10” designed for tap rooted seedlings. Germination will occur readily at a temperature between 75 °-85 ° F. The seed should be sown 1'' deep in a light, well drained soil mix, pH 5.5-7. The seedlings are transplanted to the main field after. 70-100 days is the recommended stratification period. Commercially, papaya plant is propagated by seeds sown in protrays, poly bags or raised beds in nursery. Refrigerated (32 °-40 ° F) seeds should be stored in a zip-lock bag with a bit of damp medium like peat moss or coconut coir. Germination temperatures between 15 and 30 degrees. Seeds can be stratified in a refrigerator over the winter and sown indoors in the early spring. Soak the seeds for 24 hours in water to increase the germination rates. A protective wire screen over the seedling bed may help mitigate this issue. Chipmunks an affinity for disturbing pawpaw seeds sown in ground. Seeds directly sown in the fall will receive this over the winter and generally germinate the following summer. To break dormancy, pawpaw seeds require a period of moist, cool stratification. Growing pawpaws from seed is also the best way to produce rootstock for grafting known cultivars.
