| Stock Type: | 1+0 bareroot | ||
| Time To Grow: | 10 Months | ||
| Target Specifications: | Height: N/A<br> Caliper: N/A<br> Root System: Well developed root systems for filed grown plants. | ||
| Propagule Collection: | Source of Propagules: Seed is collected with a custom designed combine from nursery stock. The plant flowers from approx. the beginning of July to the end of August. Seed is harvested the middle of September | ||
| Propagule Processing: |
Pretreatments: After drying, seed is cleaned first by hand to remove large trash. Then, it is run through the Debearder. Use the middle screen size for the Debearder, feed slowly, and cover the end of the hopper to control dust. Set the brushes out 1/4 inch out from the center and check to make sure seed is not getting damaged. Next, take the seed to the Clipper using a top screen of 1/12 and a bottom screen of 1/25. Run the good seed over the Forsberg Gravity Table. Then one more time through the Clipper. Use a top screen of 1/12 and a bottom screen of 1/17. Seed may be run through the Jesse Aspirator, with both vents wide open, being careful to check the dust bags for pure, live seed. Seed can be cleaned to 88% purity with 62,500 seeds per ounce. |

| Pre-Planting Treatments: |
Field seed is planted in the fall, therefore, is not put into cold storage. If unable to plant in the fall due to weather, store the seed dry in cold storage at 34-36 degrees F. Field seed is not damp stratified due to clumping during the drilling process. |
||
| Growing Area Preparation/ Annual Practices for Perennial Crops: |
Seed is drilled with the Love Seeder at a rate of 0.8 ounces per 45 linear feet into 3 or 4 foot wide, raised beds, consisting of a sandy loam. Adjust the drill heights so that the seed is covered only 1 times its depth. The beds should be hydroseeded with a cool-season, annual grass to protect seed over the winter months. | ||
| Active Growth Phase: | Field grown plants are topdressed twice, once in May and once in June with 13-13-13 at a rate of 200 lbs. Per acre. The fertilizer is irrigated in after application. Irrigation is run once or twice a week, depending on weather, and run for one to two hours. | ||
| Hardening Phase: | For field grown plants, reduce irrigation to slow the vegetative growth down in the fall. | ||
| Harvesting, Storage and Shipping: |
Field grown plants are lifted in late September to early November and again in the Spring if need be. The top growth should be mostly died down. Once this occurs, it is helpful to mow the tops to a more manageable size. This aids in the lifting process. Plants are undercut at 7-12 inches prior to lifting. While culling and grading is performed, the roots should be misted occasionally. Depending on weather conditions, field grown plants may be lifted and shipped in the fall. However, time and labor may require spring shipment. Field grown stock is also stored in cool, dry storage, above freezing. Again, remove dead vegetation in the culling process, and place the plants in plastic-lined bags. Do not allow root systems to dry out. Storage Duration: Approximately 4 to 6 months. Plugs and field grown bareroot plants may be shipped at any time as long as the receiver has cold storage. |
