Not known to be invasive in the US.

Propagation Goal:
plants

Propagation Method:
seed

Product Type:
Container (plug)

Stock Type:

Grow Time:
9 Months

Target Specifications:
A well developed plant suitable for transplanting with at least 12" of top growth and a healty root system.

Propagation Collection:
Seeds were collected from multiple trees within a stand of pawpaws located on the property of the USDA, NRCS Appalachian Plant Materials Center. Seeds were collected in late fall after the fruits had fully matured and fallen to the ground. Most of the fruit had been eaten by animals leaving the seeds behind.

Propagation Processing/Propagule Characteristics:
The seeds were washed to separate the seeds from the remaining pulp material.

Pre-Planting Propagule Treatments:
No pretreatment was used.

Growing Area Preparation / Annual Practices for Perennial Crops:
Pro-mix BX with biofungicide was moistened and placed in heavy plastic trays. The soil was compacted somewhat to prepare a firm seedbed.

Establishment Phase:
Seed was spread evenly on the soil surface and then covered with 1" of additional soil. The top layer was pressed down slightly to ensure good seed to soil contact. The trays were placed in the cooler (34 degrees F) for 60 days to allow for cold, moist stratification.

Length of Establishment Phase:
3 months

Active Growth Phase:
After completion of the cold stratification process, the trays were moved to the greenhouse for germination. Seedlings began to emerge after about 2 months in the greenhouse. Once the seedlings had developed sufficient root systems, They were transplanted into 1 gallon containers filled with Metro-mix 510 growing media.

Length of Active Growth Phase:
6 months
