- Water
The Red Twig Dogwood should be watered deeply once a week, applying about 1 to 1.5 inches of water each time, ensuring moisture reaches the deep roots. During hot, dry spells, watering frequency should increase to twice a week. Newly planted shrubs require consistent moisture and may need watering every few days until they are established, usually during the first growing season. Adjust the watering schedule during the fall and winter months when the plant is dormant, as it will require less water. Always check the soil moisture level before watering to prevent overwatering, as soggy soil can lead to root rot.
- Light
The Red Twig Dogwood thrives best in a spot that receives full sun to partial shade. Ideally, it should get at least 4 hours of direct sunlight daily, but it can tolerate some shade, especially in the afternoon when the sun is strongest. A location that provides morning sunlight and afternoon shade can help prevent the leaves from scorching in areas with intense summer heat.
- Temperature
The Red Twig Dogwood is hardy and can tolerate a wide range of temperatures, withstanding minimum temperatures down to -30°F. It grows optimally in temperatures between 59°F and 77°F. The plant can survive up to maximum temperatures of around 95°F but may need additional watering and protection from extreme heat to prevent stress.
- Pruning
Prune the Red Twig Dogwood in late winter or early spring to remove any dead or damaged branches and to encourage vibrant stem color, as the younger stems exhibit the brightest hues. It's beneficial to periodically remove about a third of the oldest stems to promote new growth, which should be done every 2-3 years. In addition to promoting aesthetic appeal, pruning also improves air circulation, which helps prevent disease.
- Cleaning
As needed

- Life cycle
After seed germination, the Cornus 'Ascona', commonly known as a type of Dogwood, begins its life as a seedling, establishing a root system and sprouting initial leaves. As it enters the vegetative stage, it develops a woody stem and branches, expanding its foliage and increasing in height and spread. The plant then matures and enters the flowering stage, typically in spring, producing small, star-shaped flowers surrounded by large, showy bracts which can be white, pink, or yellow depending on the variety. Following pollination, these flowers develop into fruit, usually small, berry-like drupes that can attract birds and wildlife. In autumn, Dogwoods often display vibrant foliage colors before entering a period of dormancy in winter, shedding leaves in preparation for the cold. The cycle resumes in spring as the plant breaks dormancy with new growth, initiating the next cycle of flowering and fruiting.
- Propogation
Propogation time
Spring-Early Summer
Propogation: The most popular method of propagating Cornus 'Ascona', also known as a variety of Kousa dogwood, is through softwood cuttings. This technique is typically employed during late spring or early summer when the new growth is still soft and flexible. Softwood cuttings are taken from the current year’s growth, ensuring they are about 4 to 6 inches (10 to 15 cm) long with a few leaves at the top. The lower leaves are removed, and the cut end is dipped in a rooting hormone to promote root development. The cutting is then planted in a well-draining soil mix, ensuring at least one pair of leaf nodes is below the surface. A plastic bag or a propagator can be used to cover the cutting to maintain high humidity levels and provide a mini-greenhouse effect. Consistent moisture and warmth are important until the cutting establishes roots, which usually takes a few weeks.
