WaterThe Willow Bottlebrush should be watered regularly during its first growing season to establish a deep root system. Watering once a week with about 1 to 1.5 gallons per watering should suffice. Once established, it's more drought-tolerant and will need less frequent watering. During the hot season, increase the frequency to twice a week but adjust based on rainfall and soil moisture levels. Always check the top few inches of soil for dryness before watering to avoid overwatering.
LightThe Willow Bottlebrush thrives in full sun to partial shade. The ideal spot provides direct sunlight for at least 6 to 8 hours a day. If located indoors, a sunny window or a room with ample natural light will be beneficial for the plant's growth. Avoid placing it in deep shade as it can hinder blooming and overall vitality.
TemperatureWillow Bottlebrush prefers a warm climate with temperatures ranging from 40 to 90 degrees Fahrenheit. The plant can survive temperatures down to around 20 degrees Fahrenheit but may suffer damage from frost. Ideal growing conditions are within the 70 to 85 degrees Fahrenheit range for optimal growth and flowering. Protect the plant from extreme cold by providing shelter or covering.
PruningPruning the Willow Bottlebrush is essential for maintaining its shape and encouraging a more compact growth. Prune after the flowering season, typically in late spring or early summer, to remove any dead or diseased branches and to shape the plant. You may also thin out the center to increase air circulation. It is not necessary to prune every year; doing it every 2 to 3 years or as needed to control size is sufficient.
CleaningAs needed
SoilWillow Bottlebrush thrives in well-draining, sandy loam that is slightly acidic to neutral in pH, ideally between 6.0 and 7.0. A soil mix of 2 parts sand, 2 parts topsoil, and 1 part compost or peat moss works well.
RepottingWillow Bottlebrush should be repotted every 2-3 years to prevent becoming root-bound and to refresh the soil, allowing for healthy growth.
Humidity & MistingWillow Bottlebrush prefers moderate to high humidity levels but is adaptable to average household humidity conditions.

Life cycleThe life cycle of Callistemon salignus, commonly known as White Bottlebrush, begins with seed germination, which occurs in moist soil conditions following dispersal by wind or wildlife. The seedling stage follows, marked by the emergence of the first leaves and establishment of a root system. As the plant enters the vegetative growth stage, it develops a woody stem and the characteristic lance-shaped leaves. Upon reaching maturity, which may take several years, the White Bottlebrush produces vibrant flower spikes composed of numerous individual blossoms that attract pollinators like birds and insects. After pollination, the flowers develop into woody capsules which contain seeds that will be released when mature, completing the reproductive cycle. This species also has the ability to resprout from the lignotuber after events such as bushfires, providing another means of survival and regeneration.
PropogationPropogation time
Spring-Early Summer
Propogation: The most popular method of propagating Callistemon salignus, commonly known as Willow Bottlebrush, is through semi-hardwood cuttings. This generally takes place during the late summer to early fall. To propagate, one would take cuttings of about 4 to 6 inches (10 to 15 cm) in length from the current year's growth, ensuring each cutting has several leaf nodes. Leaves are typically removed from the lower half of the cutting. The cut end is often dipped in rooting hormone to encourage root development and then placed in a well-draining potting mix. The cuttings are kept moist and in a warm environment with indirect sunlight. Roots usually develop in a few weeks, after which the new plants can gradually acclimate to outdoor conditions before being transplanted to their final location.
