Beaked stewartia Stewartia rostrata

Water

The Beaked Stewartia should be watered deeply enough to moisten the soil thoroughly each time, typically receiving about 1 to 1.5 gallons once a week during the growing season. In hotter, drier conditions, the frequency may increase to twice a week. It is essential to maintain a balance as the Beaked Stewartia prefers evenly moist soil but does not tolerate standing water around its roots. During winter months, reduce watering as the plant's growth slows down, but do not allow the soil to completely dry out.

Light

The Beaked Stewartia thrives best in conditions where it can receive partial shade to full sun. Ideal locations offer morning sunlight with protection from the intense heat of the afternoon. This plant can adapt to various lighting conditions, but too little light can lead to fewer blooms and poor growth while too much direct sunlight may scorch its leaves.

Temperature

The Beaked Stewartia favors temperate climates and is hardy in a range of 10 to 90 degrees Fahrenheit. The ideal temperature range for this plant is between 60 and 80 degrees Fahrenheit. While it can withstand brief periods of colder temperatures, prolonged exposure to freezing conditions should be avoided.

Pruning

The Beaked Stewartia benefits from pruning to maintain its shape, remove any dead or damaged branches, and encourage new growth. The best time for pruning is late winter or early spring before the new leaf buds open. Light annual pruning is typically sufficient to keep the plant healthy and well-shaped.

As needed

Soil

Beaked Stewartia thrives in acidic to neutral soil with a pH range of 5.5 to 7.0. The best soil mix for Beaked Stewartia consists of a well-draining mixture of loam, leaf mold, or compost, and sand. Adding organic matter will help retain moisture while ensuring proper drainage, which is crucial for the health of the plant.

Repotting

Beaked Stewartia generally doesn't need frequent repotting as it prefers to be left undisturbed. It could be repotted every 3 to 5 years or when it outgrows its current container. During repotting, gently tease the roots if they are circling and pot in a similarly structured soil mix.

Humidity & Misting

Beaked Stewartia prefers moderate to high humidity levels, ideally between 40% to 60%. If the air is too dry, the leaves may exhibit signs of stress. In an indoor setting, ensuring adequate humidity around the plant can maintain its health and vibrant foliage.

Suitable locations

• Indoor

  Provide bright, indirect light and maintain high humidity.

• Outdoor

  Place in partial shade and protect from harsh winds.

• Hardiness zone

  6-8 USDA

Life cycle

The Stewartia rostrata, commonly known as beaked stewartia, begins its life cycle as a seed, which upon germination in favorable conditions, typically in moist and well-drained soil, sprouts into a seedling. This seedling then enters a period of vegetative growth, establishing a root system and producing leaves as it matures into a sapling. As it continues to grow, the beaked stewartia enters the juvenile phase, during which it develops its characteristic features such as its smooth bark and serrated leaves. Upon reaching maturity, which can take several years, the plant begins its reproductive phase, producing beautiful, camellia-like flowers that attract pollinators. After pollination, the flowers develop into woody capsules that split open when dry to release seeds, thus completing the cycle. As a perennial, this tree can go through its reproductive cycle annually for many years, depending upon environmental conditions and health of the individual plant.

Propogation

• Propogation time

  Spring-Early Summer

• Propogation: The Stewartia rostrata, commonly known as Beaked Stewartia, is propagated most effectively through seed sowing. To ensure successful propagation, the best time to sow seeds is in late winter or early spring, following a period of cold stratification, which is a process meant to mimic the natural wintering-over of seeds. Stewartia seeds require a stratification period to break dormancy, often achieved by mixing the seeds with slightly moistened sand and placing them in a plastic bag. This bag should then be stored in a refrigerator, maintaining a steady temperature of approximately 33-41 degrees Fahrenheit (1-5 degrees Celsius), for a period of 1-3 months. After the stratification process, the seeds can be sown in a well-draining soil mix, barely covering them with soil. The seeds will generally germinate when exposed to temperatures around 70 degrees Fahrenheit (21 degrees Celsius). It is important to keep the soil consistently moist but not waterlogged to encourage the growth of the seedlings.
