| Scientific Name: | Artemisia douglasiana Besser | ||
| Common Name: | Douglas’ sagewort | ||
| Species Code: | ARDO3 | ||
| Ecotype: | Yosemite National Park | ||
| General Distribution: | Washington to extreme southern California, western Nevada and parts of Idaho | ||
| Propagation Goal: | Plants | ||
| Propagation Method: | Seed | ||
| ProductType: | Container (plug) | ||
| Stock Type: | 10 cubic inch conetainer | ||
| Target Specifications: | Healthy root development filling the 10 ci conetainer. | ||
| Propagule Processing: | Seed can be removed from plant material using a hammermill or brush machine. We run our seed through an air-screen with 1.40 mm top screen and 1.15 mm bottom screen with light air. | ||
| Pre-Planting Treatments: | Seed is stored in cool-dry conditions with temperatures of approximately 10° C (50° F) and relative humidity of 20 to 30%. | ||
| Establishment Phase: | We used Sunshine Mix #4. No fertilizer is added to the soil mix. Five to 25 seeds are placed on the soil surface and pressed for good seed-to-soil contact. Seed is lightly covered with pea gravel, and the soil surface is kept moist with 20 minutes of daily irrigation from overhead sprinklers for the first 30 days. Day time greenhouse temperatures range from 24 to 29° C (75 t 85° F). Night time temperatures average around 21° C (70° F). | ||
| Length of Establishment Phase: | 4 weeks | ||
| Active Growth Phase: | Our seed lot had very high viability and needed to be thinned. After full establishment, plants are fertilized once per week with Miracle Grow All Purpose Plant Food (15-30-15). After 30 days the irrigation schedule is changed to 40 to 60 minutes every other day to encourage root growth. We had to trim our plants with an electric hedge trimmer periodically as they grew and began to affect the sprinkler distribution. | ||
| Length of Active Growth Phase: | 4 months | ||
| Hardening Phase: | We backed off the water to 60 minutes every 4 or 5 days. | ||
| Length of Hardening Phase: | 1 week | ||
| Harvesting, Storage and Shipping: | Plants were deeply watered just prior to shipping. Plants were shipped in a 10° C (50° F) refrigerated truck for 2 days. | ||
