| Propagation Goal: | Plants | ||
| Propagation Method: | Seed | ||
| ProductType: | Container (plug) | ||
| Stock Type: | Plugs for seed increase field establishment | ||
| Time To Grow: | 60 days | ||
| Target Specifications: | Well-developed roots | ||
| Propagule Collection: | Predation hit some scouted coastal populations hard in 2022 | ||
| Pre-Planting Treatments: | None | ||
| Growing Area Preparation/ Annual Practices for Perennial Crops: |
On 1-15-23, Anaphalis margaritacea seed was sown in 72-well mini-plug trays from Steuwe & Sons, into Sunshine mix #4 potting media with incorporated 16-16-16 Osmocote, slow release fertilizer and Micromax micronutrients. A ¼-inch well was dibbled into each plug and approximately 5 seeds sown per cell. The seed was covered by a ⅛-inch layer of fine vermiculite. Trays were placed into a greenhouse heated to 65℉ during the day and 55℉ at night. | ||
| Establishment Phase: | The earliest germinants emerged 5 days after seeding with complete germination at 15 days after seeding. | ||
| Length of Establishment Phase: | 2 weeks | ||
| Active Growth Phase: | Trays were kept in a greenhouse heated to 65℉ during the day and 55℉ at night. The greenhouse used artificial lighting via high pressure sodium (HPS) bulbs, set to an 18-hour day. Plugs were hand watered as needed to remain moist until outplanting. | ||
| Length of Active Growth Phase: | 30 days | ||
| Hardening Phase: | Seedling trays were brought outside and lightly covered with remay cloth on 3-1-23 to acclimatize and harden off. | ||
| Length of Hardening Phase: | 2 weeks | ||
