| Propagation Method: | Seed | ||
| ProductType: | Container (plug) | ||
| Stock Type: | 107 ml (6.5 in3) container | ||
| Time To Grow: | 10 weeks | ||
| Target Specifications: | Stock Type: Container seedling. Well-developed crown and firm plug in container. | ||
| Pre-Planting Treatments: | Seeds are sown directly into target containers. Growing medium used in these cells consists of 40:20:20:20 peat:composted fir bark:perlite:pumice with Nutricote controlled release fertilizer (18N:6P2O5:8K2O with minors; 140-d release rate at 21C) at the rate of 0.5 gram Nutricote per 107 ml container. Entire racks are sealed inside plastic bags and placed into refrigeration at 1 to 3 °C for 30 days. Cells are checked weekly and kept moist throughout the stratification period. | ||
| Growing Area Preparation/ Annual Practices for Perennial Crops: |
Greenhouse growing facility. Racks are removed from stratification facilities and placed directly into greenhouses in mid-July. No additional time-release fertilizer is added to medium. Cells are irrigated lightly several times per day to ensure seeds are kept quite moist throughout the germination period. |
||
| Establishment Phase: | Germination is uniform and is usually complete in 1 to 2 weeks. Following germination, plants are fertilized with soluble 12-2-14-6Ca-3Mg at 100 ppm for 1 week. | ||
| Length of Establishment Phase: | 2 weeks | ||
| Active Growth Phase: | Plants grow very quickly during the active growth phase Soluble fertilizer 20-9-20 NPK at 150 ppm is applied weekly for 8 weeks. | ||
| Length of Active Growth Phase: | 8 weeks | ||
| Hardening Phase: | No dry-down is done to induce dormancy. Seedlings are moved to an outdoor growing area in mid-September. | ||
| Length of Hardening Phase: | 2 weeks | ||
| Harvesting, Storage and Shipping: |
Harvest Date: Mid-October Storage Conditions: Seedlings are usually outplanted in fall. No storage except in outdoor growing area. Plants are well irrigated prior to shipping and shipped in containers. |
