Pruning

Water
Joe Clematis prefers to be kept in moist but well-drained soil, so it's important not to let it dry out completely nor to waterlog the roots. During the growing season, water the plant once a week with about 1 gallon of water, ensuring it reaches deep into the soil to encourage deep root growth. In hot or dry weather, you might need to water twice a week. During the winter, reduce watering since the plant's water requirements decrease. Always adjust your watering frequency based on rainfall and check the soil moisture levels regularly.
Light
Joe Clematis thrives best in a spot with full sun to partial shade. Ideal lighting conditions involve getting around 6 hours of sunlight daily, so positioning the plant in a location where it can receive morning sun and afternoon shade is often recommended. This will help ensure the Joe Clematis gets enough light for growth without being exposed to the harsh, potentially damaging afternoon sun.
Temperature
Joe Clematis grows well in a range of temperatures and is hardy in USDA zones 4 through 9. The plant can survive winter temperatures down to about -30°F and summer temperatures as high as 85°F. For optimal growth, the Joe Clematis prefers temperatures between 65°F and 75°F. Avoid placing it in areas with extreme temperature fluctuations or drafts.
Pruning
Prune Joe Clematis to maintain plant health, control growth, and enhance flowering. The best time to prune this early-flowering clematis is immediately after the blooming period, which is typically in early spring. Cut back the stems that have just finished flowering to just above a set of healthy buds or a strong side shoot, which will encourage new growth and a subsequent bloom period. Remove any dead or damaged stems any time of the year as soon as you notice them.
Cleaning

Life cycle
Clematis 'Joe', also known as Joe Clematis, begins its life as a seed, which germinates in moist, well-draining soil where it receives plenty of indirect sunlight. The seedling develops into a juvenile plant with a network of roots and shoots, which over time becomes a mature plant with a robust, climbing vine structure and woody stems. During spring and early summer, it enters a vigorous growth phase, during which it produces large, showy white flowers that attract pollinators for sexual reproduction. Following pollination, the plant develops seed heads with feathery tails known as achenes, which disperse with the help of wind, allowing for the colonization of new areas. Over the seasons, the plant will enter a period of dormancy, usually in the colder winter months, where growth slows significantly, and it conserves energy. As the cycle repeats annually, the plant grows larger, and can live for many years, continuing to flower and produce seeds each season.
Propogation
- Propogation time
  Spring to early summer
- Clematis 'Joe', a hybrid variety known for its ornamental value, is commonly propagated by layering, a method well-suited for hobbyists and gardeners. The best time to begin propagation by layering is in late winter or early spring, before the plant starts to actively grow. To propagate Clematis 'Joe' using layering, you should identify a long, healthy stem that can be bent down to the ground. While still attached to the parent plant, make a small nick on the underside of the stem, apply rooting hormone to the wounded area to encourage root development, then secure the stem in a shallow trench filled with moist soil. Cover the nicked section with soil while leaving the rest of the stem and the tip above ground. The trench should be kept moist but not waterlogged to provide the right conditions for root growth. After several months, once the stem has rooted, it can be cut from the parent plant and transplanted to a desired location.
