| Family Scientific Name: | Juncaceae | ||
|---|---|---|---|
| Family Common Name: | Rush family | ||
| Scientific Name: | Juncus effusus L. | ||
| Common Name: | Common rush | ||
| Species Code: | Common rush | ||
| Ecotype: | Yosemite National Park | ||
| General Distribution: | Throughout North America | ||
| Propagation Goal: | Plants | ||
| Propagation Method: | Seed | ||
| ProductType: | Container (plug) | ||
| Stock Type: | 10 cubic inch conetainer | ||
| Time To Grow: | 5 months | ||
| Target Specifications: | Healthy root development filling the 10 ci conetainer. | ||
| Propagule Processing: | Seed can be removed from plant material using a brush machine or hammermill. We run our seed through an air-screen with 1.15 mm top screen and solid bottom screen with no- to very light light air. Finer material can be effectively removed using a gravity table. | ||
| 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%. No stratification treatments are necessary. | ||
| Establishment Phase: | We used Sunshine Mix #4. No fertilizer is added to the soil mix. Five to ten seeds are placed on the soil surface and pressed for good seed-to-soil contact. Conetainer trays were placed in greenhouse ponds filled with water to about the same level as the soil in the cones (about 7 to 8 inches). This allowed the cones to imbibe water maintain full saturation. 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 most cones had multiple plants in them and required thinning. 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 trimmed our plants occasionally with an electric hedge trimmer. Every 2 or 3 weeks we drained the greenhouse ponds and allowed the soil to dry for a day or two. | ||
| Length of Active Growth Phase: | 4 months | ||
| Length of Hardening Phase: | none | ||
| 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. | ||
