Clematis (Queen of the Vines)
Clematis are the most popular of all hardy vines. They are fast growing and produce an exceptional amount of bloom. Clematis come in a wide range of flower colors, sizes, shapes, heights and bloom times. Clematis are very long-lived and benefit from proper site selection where they can be left undisturbed for years. Most require a support structure, such as a fence or trellis, to which thay can attach.
Plant: Clematis prefer a neutral soil, pH 5.7 - 6.4. Center in pot and plant crown 1-2" below the soil surface. Spread spiraling roots evenly throughout soil.
Trellis: Position trellis at time of planting to prevent root and stem damage later.
Pinch: Pinch sprouted clematis back to 2 sets of leaf pairs per stem. This will promote better branching and produce fuller containers. Inspect crop regularly and keep growing shoots trained to the trellis to prevent tangling and damage.
Grow: Grow in full sun at 55 - 60F minimum night temperatures. After growth appears, fertilize with 200 ppm Nitrogen every 7 - 10 days.
Water: Keep evenly moist. To prevent diseases, water early in the day and keep foliage dry.
Site Selection & Planting info: For best flowering, select a site that is well-drained with a minimum of 4 hours of sunlight per day. Clematis prefer their roots to be cool. If planted in full sun, surround clematis with perennials or smaller shrubs that provide shade to the crown area. Homeowners should plant their potted clematis so the crown is 2 - 4" below soil level. Keep moist and fertilize regularly.
| Growing Temperature: | Grow in full sun at 55 - 60F minimum night temperatures |
|---|---|
| Soil pH: | 5.8 to 6.5 |
| Fertility: | Clematis are heavy feeders when they are growing fast. Fertilize with a general-purpose fertilizer at a rate of 150 to 200 ppm nitrogen once per week |
| Pests and Diseases: | |
| Potting and Timing: | |
| Moisture: | Let the soil get on the dry side before watering, but not dry to the point of wilting. |
| Planting Level: | Center in pot and plant crown 1-2" below the soil surface.
Position trellis at time of planting to prevent root and stem damage later. |
| PGRs/Pinching: | Prune Clematis as needed to maintain vigorous growth. Leave 2 sets of nodes from the crown on the first pinch. Later pinches leave 2 sets of nodes from the previous pinch. Pruning will increase the branching of the Clematis and will also develop a strong root system.
Stop pruning 6 to 8 weeks before the targeted sales date to produce a blooming Clematis |
