watering
For Clematis 'Jackmanii', water thoroughly and deeply at least once a week, preferably twice. The plant should receive 1 to 2 inches of water each time. In hot weather, water it more often to prevent the plant from drying out. Water early in the day so that the plant has time to dry out before nightfall. Avoid wetting the leaves to prevent disease.
sunlight
Clematis 'Jackmanii' prefers full sun for most of the day in order to thrive. If grown in partial shade, it will likely produce fewer flowers and lose its lush foliage and vigor. But, in very hot climates, some afternoon shade is beneficial to prevent sunburn and wilting. The best light exposure for this species of clematis is 4 to 6 hours of direct sunlight during morning and early afternoon and then 5 to 7 hours of indirect light in late afternoon and early evening.
pruning
For the Clematis 'Jackmanii' plant species, it is recommended to prune at least twice a year, once in late winter and once in late summer. For late winter pruning, it is best to wait until late February or early March, after the plant has gone dormant and the risk of frost has passed. At this stage, remove any dead or damaged stems from the previous season. The rest of the stems should be cut back to the third pair of healthy buds from the base of the stem. For late summer pruning, it is best to wait until late August or early September when the flowering display has begun to fade. Cut back the stems of the Clematis 'Jackmanii' to about 20-30 cm above ground depending on how much the plant has grown since winter pruning. This will produce a renewed flowering display that will last until the end of October. In summary, the Clematis 'Jackmanii' should be pruned twice a year in late winter (late February/early March) and late summer (August/September).

FAQ
Can Clematis plants grow in pots?
Yes, Clematis plants can definitely be grown in pots. When planting a Clematis in a pot make sure to use a larger size pot with drainage holes and fill it with a mix of well-draining potting soil and compost. Ensure to keep the root area cool and the pot in a sunny location while providing regular water and fertilization. Check the plant almost daily to make sure it is not becoming too dry. Clematis can do well in a pot and with the right care and conditions, they will thrive.
Are Clematis plants self-pollinating?
No, clematis plants are not self-pollinating. Clematis plants need pollinators such as bees, butterflies, moths and other insects to transfer pollen from the male anthers to the female stigma of the flower in order to produce viable seed. Pollination must also occur within relatively close proximity of the same species in order to create viable hybrid plants.
Can Clematis plants be grown as a houseplant?
Yes, Clematis plants can be grown as a houseplant. It is best to grow them in a pot with full sun and a soil that is rich in organic material and retains moisture. When potting the plant, place a stake or trellis next to the pot so that the vine can climb when it begins to grow. Be sure to water your Clematis plant regularly to keep it healthy and growing. Additionally, keep an eye out for pests and treat with natural insecticides as necessary.
Could Clematis plants survive in a colder climate?
Yes, Clematis plants can survive in colder climates with proper preparation. If planted in the fall, proper mulching should be done to protect the roots from cold temperatures. If planted in the spring, they should be watered frequently to help them adjust to the cooler temperatures more quickly. If temperatures drop below -20°C ( -4°F), additional measures may need to be taken such as the application of protective wraps and thermal insulation. Additionally, plants in exposed areas should be protected from the wind to prevent excessive dehydration. With the right measures in place, Clematis plants can easily survive in colder climates.
Could Clematis plants be grown in a greenhouse?
Yes, clematis plants can be grown in a greenhouse. Due to their vine-like growth habit and tropical native origins, clematis plants thrive in the moist and warm environment of a greenhouse. Clematis are generally grown from cuttings or from dividing existing plants, and benefit from regular pruning and fertilizing. They will also enjoy the indirect light of a greenhouse and the protection from strong winds and temperatures that the humidity and contained environment provides.
