Propagule Processing: Seeds are hand cleaned with screens to remove chaff.
Seed longevity:N/A
Seed dormancy is classified as non-deep physiological dormancy.
Seeds/Kg: N/A
% Germination: 80%
Pre-Planting Treatments: 5 month outdoor cold, moist stratification. Seeds are sown in late fall, irrigated and left in the outdoor nursery for the winter.
Growing Area Preparation/
Annual Practices for Perennial Crops:
Sowing Method: Direct Seeding. The tiny seeds are surface sown or lightly covered with perlite.
Growing medium used is soilless growing media of 6:1:1 sphagnum peat,vermiculite and perlite with Osmocote controlled release fertilizer (13N:13P2O5:13K2O; 8 to 9 month release rate at 21C) and Micromax fertilizer (12%S, 0.1%B, 0.5%Cu, 12%Fe, 2.5%Mn, 0.05%Mo, 1%Zn) at the rate of 1 gram of Osmocote and 0.20 gram of Micromax per 172 ml conetainer.
Establishment Phase: Seeds germinate in early spring (May)under fluctuating spring temperatures.Medium is kept slightly moist during germination by misting twice per day. Germination is usually complete in 1 to 2 weeks and seedlings are thinned at this stage.
After seedlings are established, they must dry down between irrigations. This species has a fleshy root system are requires good medium aeration and careful irrigation practices.
Length of Establishment Phase: 4 weeks
Active Growth Phase: Plants are fertilized with 20-20-20 liquid NPK at 100 ppm weekly during the growing season.
Length of Active Growth Phase: 12 weeks
Hardening Phase: Plants are fertilized with 10-20-20 liquid NPK at 200 ppm in early fall. Containers are leached with water, and irrigation is gradually reduced through September and October.
Length of Hardening Phase: 4 weeks
Harvesting, Storage and Shipping: Total Time To Harvest:7 months
Harvest Date: September
Storage Conditions: Overwinter in outdoor nursery under insulating foam cover and snow.
Length of Storage: 5 months
