| Stock Type: | 262 ml (16 in3) container | ||
| Time To Grow: | 16 weeks | ||
| Target Specifications: | Stock Type: Container seedling Root System: Firm plug in container. | ||
| Pre-Planting Treatments: | Seeds are placed in fine mesh bags into a 1% hydrogen peroxide (3:1 water/3% hydrogen peroxide) soak for 24 hours, rinsed, and placed in water for an additional 24 hours. Seeds do not require stratification. | ||
| Growing Area Preparation/ Annual Practices for Perennial Crops: |
Greenhouse growing facility. Seeds are directly sown into containers. Seeds are lightly covered with nursery grit. Growing medium used is 40:20:20:20 peat:composted fir bark:perlite:pumice with Nutricote controlled release fertilizer (18N:6P2O5:8K2O with minors; 180-d release rate at 21C) at the rate of 1.5 gram Nutricote per 262 ml container. |
||
| Establishment Phase: | Germination is fairly uniform and is usually complete in 14 days. Following germination, plants are fertilized with soluble 12-2-14-6Ca-3Mg at 75 ppm for 1 week. | ||
| Length of Establishment Phase: | 2 to 3 weeks | ||
| Active Growth Phase: | Seedlings grow rapidly throughout the active growth phase. During the growing season, fertilization depends on weather. Soluble fertilizer (20-9-20 NPK, 20-18-18 NPK, or 17-5-24 NPK) at a rate of 100 to 150 ppm is applied weekly throughout the growing season. Flowering occurs in the first year if sown early late winter/early spring. Seed increase/collection can be done during the first growing season. | ||
| Length of Active Growth Phase: | 14 weeks | ||
| Hardening Phase: | No dry-down is done to induce dormancy. Seedlings are moved to an outdoor growing area in early to mid September. | ||
| Length of Hardening Phase: | No dry-down is done to induce dormancy. Seedlings are moved to an outdoor growing area in early to mid September. | ||
| 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. |
||
| Other Comments: |
Wetland classification: FAC B. occidentalis is most often found in shady areas along streams. |
