WaterThe Star Magnolia requires thorough watering to keep the soil consistently moist but not waterlogged. During the growing season in spring and summer, it should be watered once a week with approximately 1 to 1.5 gallons of water for a young plant; mature trees may need more depending on size and weather conditions. In hotter, drier periods, frequency should increase to twice a week, but it's important to let the soil dry out slightly between waterings. In the fall and winter, reduce the watering frequency as the plant goes dormant and requires less water.
LightStar Magnolias thrive best in full sun to partial shade. They should be planted in a spot that receives at least 4 to 6 hours of direct sunlight daily, but they can also benefit from some light afternoon shade in hotter climates to protect the blooms from fading.
TemperatureStar Magnolias are hardy in a range of temperatures and can tolerate a minimum of about 20 to -10 degrees Fahrenheit in winter. They grow optimally at average garden temperatures, but it's best to ensure they are not exposed to sudden freezes during their flowering period in spring. Ideal growing temperatures for these magnolias range from 65 to 75 degrees Fahrenheit during the growing season.
PruningPruning is generally done to shape the Star Magnolia or remove any dead or damaged wood, which helps maintain the tree's health and appearance. The best time to prune is soon after the tree finishes blooming in late spring to early summer. Prune sparingly as excessive cutting can reduce flowering; once a year is typically sufficient.
CleaningNot needed
SoilStar Magnolia requires well-draining, acidic to neutral soil with a pH of 5.5 to 7.0. A mixture of loamy soil with peat moss and compost is ideal to retain moisture while providing adequate drainage and nutrients.
RepottingStar Magnolias are slow growers and typically do not need to be repotted often. Repotting every 3 to 5 years or when the root system outgrows the container is sufficient.
Humidity & MistingStar Magnolia thrives in average outdoor humidity levels; they do not require special humidity conditions. Protection from strong winds can help maintain adequate humidity around the plant.

Life cycleThe Star Magnolia ('Centennial') begins its life cycle as a seed, which, after a period of stratification to overcome dormancy, germinates in spring. The seedling stage follows, characterized by initial root growth and the emergence of the first leaves. As it enters the vegetative stage, the plant focuses on leaf and stem growth, developing its characteristic bushy habit. Once mature, it enters the flowering stage, typically in early spring, producing fragrant, star-shaped white flowers. After pollination, typically by insects, the flowers develop into aggregate fruit with red seeds, which are dispersed to begin a new life cycle. In the final stage, the plant experiences senescence, where growth slows and, ultimately, the plant dies, although individual Star Magnolias can live for many decades with proper care.
PropogationPropogation time
Early Spring
The most popular method to propagate Magnolia stellata 'Centennial', commonly known as the Star Magnolia, is through hardwood cuttings. This process involves taking a cutting of about 6 to 8 inches (15 to 20 centimeters) in length from a healthy, mature plant during the dormant season, which is typically late fall or early winter. The cutting should have several nodes and be taken from the current or previous year's growth. The bottom cut should be made just below a node, and the top cut should be made just above a node to maximize potential rooting areas. The cutting is then dipped in rooting hormone to encourage root development and planted in a well-draining soil mix. It should be kept at a consistent moisture level and in a protected environment until roots have formed and the plant can be transitioned to its permanent location.
