| Common Name: | Subalpine spiraea | ||
| Species Code: | SPISPL | ||
| Ecotype: | Subalpine fir forest, Two Medicine, 2000 meters elevation. | ||
| General Distribution: | S. splendens var. splendens is found from British Columbia to Sierran California, east to southeast B.C., Idaho, Montana, and eastern Oregon. It is found mostly in higher elevation forests. | ||
| Propagation Goal: | plants | ||
| Propagation Method: | vegetative | ||
| ProductType: | Container (plug) | ||
| Stock Type: | 3L containers | ||
| Time To Grow: | 16 Months | ||
| Target Specifications: | Stock Type: Container cutting<br> Height: 20cm<br> Caliper: 8 mm<br> Root System: Firm plug in Container. | ||
| Propagule Collection: | Summer softwood stem tip cuttings were collected in late May after snowmelt. | ||
| Propagule Processing: | Cuttings are collected in plastic bags and are kept under refrigeration prior to pretreatment. | ||
| Pre-Planting Treatments: |
Vegetative Propagation Method: Pre-Rooting Cutting Treatments: Cuttings were cut into 15 to 20 cm lengths and 8 mm in caliper. Cuttings were treated with 5000 ppm liquid IBA, and struck in mist bed with bottom heat. Rooting %: 84% |
||
| Growing Area Preparation/ Annual Practices for Perennial Crops: |
The outdoor mistbed has automatic intermittent mist that is applied at 6 second intervals every 6 minutes. Too frequent misting will result in leaf and stem rot. Bottom heat is maintained at 21C with heating cables 12 cm beneath rooting media. Rooting media is 50% perlite and 50% sand. Mistbed is covered with shadecloth during rooting. | ||
| Establishment Phase: | Time to Transplant: 4 weeks. After cuttings have rooted they are potted into 3L containers using 70% 6:1:1 milled spaghnum peat,perlite, and vermiculite and 30% sand 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 5 grams of Osmocote and 2.0 grams of Micromax per 3L container and placed in shadehouse for the rest of the growing season. | ||
| Length of Establishment Phase: | 4 weeks | ||
| Active Growth Phase: | Growth is rapid following transplanting from the mistbed to 3L containers. Plants were fertilized bi-weekly with 20-10-20 liquid NPK at 100 ppm. Plants were multi-stemmed and root tight in 3L (1 gallon) containers in 4 months. | ||
| Length of Active Growth Phase: | 12 weeks | ||
| Hardening Phase: | Plants were fertilized with 10-20-20 liquid NPK at 200ppm during September and October and given one final irrigation before overwintering. | ||
| Length of Hardening Phase: | 4 weeks | ||
| Harvesting, Storage and Shipping: |
Total Time to Harvest: 1.3 years Harvest Date: September Storage Conditions: Overwinter in outdoor nursery under insulating foam cover and snow. |
||
| Length of Storage: | 5 months | ||
