Growing Area Preparation/
Annual Practices for Perennial Crops:

Propagation Environment: Refrigerator, greenhouse and lath house to stratify, plant and grow.
Container Type and Volume: 1 gallon.
Growing Media: Sunshine Mix #1 or #3.
Establishment Phase: Sowing Date: Spring.
% Emergence and Date: N/A.
Sowing/Planting Technique: By hand sowing seeds.
Establishment Phase: Seeds in flats must be kept semi-moist before and during germination.
Active Growth Phase: Rapid Growth Phase: Over watering may cause overgrown, growthy plants with large roots and tops which may become planting problems.
Hardening Phase: Hardening Phase: Potted plants from greenhouse are moved to the lath house for several weeks, before transplanting in the spring or fall.
Harvesting, Storage and Shipping: Harvest Date: Fall.
Storage Conditions: Clean seeds with moist soil media stored in a refrigerator, after seed is pretreated with acid and washed off.
Length of Storage: Storage Duration: At least two years.
Outplanting performance on typical sites: Outplanting Site: Chickasaw National Recreation Area, Sulphur, Oklahoma.
Outplanting Date: Transplant in early spring or fall.
Other Comments: Vegetative Propagation Method: Bare-root seedlings.
Propagator: N/A.
Comments: Bare-root seedling may be transplanted in spring. Avoid hot, dry months without supplemental watering.
