Propagation Goal: plants
Propagation Method: seed
ProductType: Container (plug)
Stock Type: 2 1/2 inch container
Time To Grow: 10 Months
Target Specifications: firmly rooted in a 2 1/2 inch container
Propagule Collection: Seed was collected when ripe in late spring/early summer.
Pre-Planting Treatments: seedsown fresh
Growing Area Preparation/
Annual Practices for Perennial Crops:
Growing Environments: A fully automated greenhouse and a quonset equipped with heater and limited cooling capacity.
Containers: Seed sown into ITML brand 128 cell plug trays.
Plugs transplanted into T.&O. Plastics brand SVD 2 1/2 inch containers.
Media: Seed sown into Fafard Super Fine Germinating Mix. Plugs transplanted into Sunshine SB300 Universal bark mix.
Establishment Phase: Sow date was late July. Seeds were hand sown 5 to 7 seeds per cell to produce a clump. Seed was not covered because light aids in germination. Flats were grown for 12 weeks in a shaded greenhouse under an automated mist system set at 3 seconds of mist every 30 minutes. Air temperature was set at 65 F and bottom heat was run at 60 F. Flats were moved to a shaded quonset for 16 weeks. Temperatures were kept as close to 38 F as possible but not allowed to go below freezing. Flats were then moved back to initial greenhouse until germination. After germination, flats were moved to a fully automated greenhouse. Temperatures were set at 68 F days and 64 F nights. Day length was extended to 12 hours using HID lights. Seedlings were hand watered when dry and fertilized weekly with 20-2-20 fertilizer at 200 ppm.
Length of Establishment Phase: 33 weeks
Active Growth Phase: Plugs were transplanted when firmly rooted in mid March. Plants were grown in a fully automated greenhouse where temperatures were set at 65 F days and 61 F nights. Day length was extended to 12 hours using HID lights. Plants were hand watered when dry and fertilized weekly with 20-10-20 fertilizer at 237 ppm.
Length of Active Growth Phase: 8 weeks
Hardening Phase: Plants were moved outdoors to a cold frame in late May.
Length of Hardening Phase: 2 weeks
