| Target Specifications: | Height: 7 cm, 8 to 10 true leaves<br> Caliper: n/a<br> Root System: Firm plug in container. | ||
| Propagule Collection: | Seeds are hand collected in July and August when achenes are easily separated from receptacle. Seeds are grey at maturity. Seeds are collected in paper bags and kept in a well ventilated drying shed prior to cleaning. | ||
| 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 | ||
