Planting & Care for Sweet Autumn Clematis Vines (Clematis paniculata)
Preparation
- Clematis like to have their top growth in full sun with their roots in the shade.
- Roots can be shaded with groundcover plants or with other low-growing subjects, with paving slabs or with even a deep mulch of organic matter.
- Clematis grow well in any well-drained, reasonably rich soil containing plenty of humus.
- They are particularly suitable for chalky soils.
- Trim back dead tops early in spring before new growth begins.
- Because this clematis is so vigorous, established plants cut back in spring can grow 15' or more in one season.
- Clematis plants are type 3 (can be late summer or early fall bloomers)
- Keep the plants permanently mulched with organic matter.
- These are “twiners” – climbing plants that twine their new shoots entirely around a support.
- Clematis should not be allowed to suffer from lack of moisture, so water plants well during rainless periods if the soil starts to dry out.
- Plant in February or March.
Planting Groundcovers/Vines
- Groundcovers/Vines: Planting bed should consist of 6-8" of topsoil, well mixed with approximately 2" of peat moss.
Pruning - After Planting
- Groundcovers/Vines: No pruning is needed right away.
Pruning - Through-out the Season
- The only pruning these plants need is thinning when they become congested. This is done after flowering.
- If rejuvenation pruning is needed, cut down the entire plant to within 12 inches of the ground after flowering every three to four years.
Watering - After Planting
- Plants typically take approximately 6 weeks to establish new roots in your soil. During this period, water plants as often as every 2-4 days at the start and at least a minimum of once per week.
- Beyond the six-week establishment period, water once per week unless rain occurs.
- Remember to check soil moisture by sticking your finger into the soil around 3”.
Watering - Through-out the Season
- After the first season, plants should only be watered during extended periods without rain.
- Clematis should not be allowed to suffer from lack of moisture, so water plants well during rainless periods if the soil starts to dry out.
- How do you know if your plants need water? The easiest way to tell is to touch the soil around the roots. If it is moist, there is no need to water. If it is dry, give it a good soaking with the hose end (no nozzle) watering the soil only, not the leaves.
- Stick your finger into the soil around 3” to check soil moisture.
