Propagation Collection:
Pandanus tectorius trees are either male or female. Female trees produce a large, segmented fruit somewhat resembling a pineapple. Male trees produce large clusters of tiny, fragrant flowers surrounded by white to cream colored bracts. Collect uttings from male and female trees.
Collect softwood stem cuttings in early summer when the leaves have expanded and the stems are firm. During collection, stem cuttings need to be kept moist and cool, and must be treated immediately after collection.

Propagation Processing/Propagule Characteristics:

Pre-Planting Propagule Treatments:
Each cutting must have a healthy terminal shoot bud. Stems are cut to 15 to 20 cm (6.0 to 8 in) lengths, and all mature leaves are removed except the terminal leaves. Leaf buds in the axils of leaves are not removed and will form new leaves once the cuttings are well rooted. Cuttings are directly stuck into containers filled with moistened medium. We do not use rooting hormones.

Growing Area Preparation / Annual Practices for Perennial Crops:
The Yap Agroforestry nursery a year round growing season with periods of high rainfall.
The facility is comprised of one large greenhouse, shade structures, and mist propagation beds, and an outdoor growing compound. All propagation environments are utilized at different stages of seedling growth to protect seedlings from heavy rains, andprovide to temperature and shading variance during production. We irrigate all containers by hand, but are investigating a sub-irrigation system for the nursery. We use fertilizers if when they are available.

Establishment Phase:
Cuttings begin to form roots about 4 weeks after sticking. We plant them in polybags filled with a growing medium of 2:1:1 (v:v:v) sand, seaweed compost, and topsoil. Cuttings are kept evenly moist during establishment.

Length of Establishment Phase:
2 months

Active Growth Phase:
Once cuttings are well rooted, new leaves from the axillary leaf buds begin to form. We keep cuttings in the shelterhouse during active growth to protect them from wind and heavy rains.

Length of Active Growth Phase:
2 months

Hardening Phase:
Irrigation frequency and duration is gradually reduced for 4 to 8 weeks prior to outplanting.

Length of Hardening Phase:
1 month

Harvesting, Storage and Shipping:
Containerized cuttings are stored in the open growing compound until moved to outplanting site.

Length of Storage:
Variable; depends on outplanting date.
