| Growing Area Preparation/ Annual Practices for Perennial Crops: |
Growing Environment: Fully automated greenhouse. Containers: Seeds sown into ITML brand 128 cell plug trays. Plugs transplanted into T.&O. brand SVD 2 1/2 inch containers. Media: Seeds sown into Fafard Super Fine Germinating Mix. Plugs transplanted into Sunshine SB300 Universal bark mix. |
||
| Establishment Phase: | Sow date was mid February. Seeds were hand sown 2 to 3 seeds per cell to compensate for possible lower germination rates. Seeds were covered with a thin layer of coarse vermiculite. Flats were watered in with mist and placed 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 70 F. Seedlings were moved to a full sun greenhouse after germination. 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. Seedlings were thinned to one per cell. | ||
| Length of Establishment Phase: | 12 weeks from sowing until plugs were ready to transplant. | ||
| Active Growth Phase: | Plugs were transplanted when firmly rooted. Plants were grown in a full sun 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 with 20-10-20 fertilizer at 237 ppm weekly. | ||
| Length of Active Growth Phase: | 6 weeks | ||
| Hardening Phase: | Plants were moved outdoors to a cold frame in early June. | ||
| Length of Hardening Phase: | 2 weeks | ||
