Growing and Caring for Jackman Clematis

Plant Care

Jackman Clematis blossoms with a bit of TLC, especially under concerning growing conditions. This plant requires a lot of sunlight, consistent watering, and well-draining soil. It’s relatively low-maintenance, but it does enjoy a little trimming every now and then to keep giving you big, beautiful blooms. With proper care, you will have a showstopper in your garden for years to come with your Jackman Clematis.

Light

Jackman Clematis thrives in full sun, promoting lots of blooms. It should get a minimum of 6 hours direct sunlight a day. However, it can tolerate partial shade, particularly in hotter climates, as long as it still receives some sunlight.

Soil

Clematis like a rich, well-drained soil with plenty of organic matter. They are not especially fussy about soil type, although sandy or loamy soils are best. As for soil pH, it's best to be slightly acidic to neutral (6.0-7.0) for proper growth and flowering.

Watering

Water Jackman Clematis occasionally, allowing the soil to dry out gradually, but never fully. This plant doesn’t enjoy having wet roots, so make sure the soil drains well. Water in dry weather to promote deep roots, but don’t overwater as it may lead to root rot.

Pruning

Pruning Jackman Clematis is an important aspect of their care, particularly to keep it well-shaped and healthy. A late-blooming type, it flowers on new growth, so responds well to heavy pruning in early spring before new shoots emerge. Prune last year’s growth back to 12-18 inches from the ground to encourage strong new growth. Dead or damaged stems can be cut back during the growing season as well. That way you can also keep the plant looking tidy and encourage more blooms.

If your Clematis has grown too leggy or out of shape, prune it back to a manageable size, but never remove more than one-third of the plant at once to avoid stressing it.

Propagating

Jackman Clematis propagates easily, and that’s an added bonus. Two common ways are by cuttings or layering.

• Cuttings: After spring or summer, take cuttings from healthy stem tips (about 4-6 inches long). Strip the bottom half of the cutting of leaves and dip the cut end in rooting hormone. Place it in a pot with moist, well-draining soil, moving it to a shaded, humid space until roots form.
• Layering: Carefully bend a healthy stem down toward the ground, bury it in soil and pin it in place with a U-shaped pin. After it roots, you can snip the stem away from the main plant and transplant it.

Dividing older plants and growing from cuttings are two effective ways to multiply your Clematis collection without the expense of buying new plants.

Growing in Pots

Jackman Clematis will grow in pots, too, so you know that even if you don’t have a big garden, you can still enjoy their blooms. Select a container at least 18-24 inches deep and wide for its root system. Use a well-draining potting mix, and make sure your pot has drainage holes. Clematis can grow in pots, but need regular watering and a balanced fertilizer every 4-6 weeks during the growing season. Since Clematis are naturally climbers, give them a trellis or stake for vertical support.

Container-grown Clematis often require more water than those grown in the ground, particularly in warm weather. In colder climates, bring pots indoors or provide winter protection.

Overwintering

Jackman Clematis is considered hardy in USDA zones 4-9. For root protection in colder regions, it is relevant to protect the roots in winter months. After the first frost, cut the plant back to around 6-8 inches above the ground.

Pack on a thick layer of mulch around its base, to insulate its roots. In pots, move the plant inside or place it in a cool, dry location to avoid freezing. Clematis require no special winter care, but some protection will help ensure that they come back healthy each spring.

Blooming

The main attraction of Jackman Clematis is its showy flowers. These vibrant purple flowers appear from mid-summer to early fall, often covering the plant in a stunning display. Clematis flower on new growth, so annual cuts stimulate more blooms. To encourage continued flowering, make sure your plant receives full sun, especially in the morning, which dries moisture from the leaves and inhibits fungal diseases. Give their roots a cool blanket with mulch, because Clematis like had their roots covered but their tops up in the sun.

Common Issues

Jackman Clematis is typically resistant to both pests and diseases, though some issues can still occur. Watch out for:

• Powdery Mildew: This fungal disease presents itself as white, powdery flecks on leaves. Be sure your plant gets good airflow and do not water overhead.
• Aphids and Spider Mites: These pests occasionally attack Clematis plants particularly in drier conditions. Spray them off with water or an insecticidal soap.
• Clematis Wilt: A A bacterial disease that makes stems suddenly wilt. Quickly remove infected stems to control spread.
• Root Rot: Root rot is common in overwatered plants or plants in poorly-drained soil. Make sure the soil is well-draining, and avoid waterlogging.

With the proper care — adequate sunlight, well-draining soil and regular pruning — it can flourish year after year, transforming your outdoor area. Whether you have it in ground or in a pot, this versatile plant extends a cascade of stunning blooms from summer into fall.
