| Common Name | Goldenrod |
| Genus | Solidago |
| Species | S. canadensis |
| Family | Asteraceae |
| Life Cycle | Hardy Herbaceous Perennial |
| Tray Size | 50 |
| Plug Care | Plant soon after receiving plugs - water well for the first two weeks after planting to allow the plugs to get established, then water only when the soil dries. |
| Netting / Staking | Not necessary |
| Temperature Range | Hardiness zones 3-9 |
| Spacing | 12" |
| Soil Preference | Loose, well draining, amended with organic matter |
| Day Length | Quantitative long day plant - requires a minimum of 13 hours daylight in order to elongate and flower. Grow in full sun. |
| Pinching | Yes - pinch approximately 3-5 weeks after planting when the main stem starts to elongate. Cut low on the central stem to encourage strong side shoot development. |
| When to Plant | Plugs can be planted any time of the year but perform best when planted in cool conditions - early spring in most zones. |
| Harvesting | Harvest when just the top flowers in the inflorescence begin to open. |
| Post Harvest Care | Cut stems should be placed immediately into cool water. Floral conditioners help to extend vase life. To avoid botrytis in the cooler, dry any residual moisture on the foliage before storing. Can be kept for a few days in the cooler if not needed right away. |
| Diseases / Insects | Aphids, white fly, leaf miner, caterpillar, powdery mildew, rhizoctonia, agrobacterium |
| Bailey's Notes | As with any quantitative long day plant, artificial lighting can be used in a greenhouse during the winter months to mimic long day lengths and initiate early flowering. |
