Propagation Goal:
plants

Propagation Method:
seed

Product Type:
Container (plug)

Stock Type:
D 40 containers

Grow Time:
1 Years

Target Specifications:
Height: N/A
Caliper: N/A
Root System: Firm root plug in container.

Propagation Collection:
Seeds are hand collected from sites within the Park when fruits have fully matured.

Propagation Processing/Propagule Characteristics:
Seeds are stored in sealed containers under refrigeration between 40 and 60 F.

Pre-Planting Propagule Treatments:
Seeds are naturally stratified outdoors during fall months.
Sowing Methods: Seeds are sown in Dyna flats with drainage holes containing a medium of 1.5 parts vermiculite, 1 part sterile sand, 1 part coarse turface, and 2 parts peat moss (v:v:v:v). Trays are watered thoroughly after sowing and are not allowed to dry out completely during stratification and germination.

Growing Area Preparation / Annual Practices for Perennial Crops:
Seedlings are grown in a shadehouse from March through October.

Establishment Phase:
We transplant emergents at the cotyledon stage into D 40 pots containing the same media described for germination. It is important to transplant at the cotyledon stage as root deformation will occur if delayed beyond this stage of development. We sometimes incorporate 13:13:13 NPK Osmocote time release fertilizer into media.

Length of Establishment Phase:

Active Growth Phase:
Seedlings are hand watered throughout the growing season after they are well established. Throughout the active growth phase, we irrigate when containers are nearly dry as a method of hardening the plants while they are being grown.
