    The Sweet Box should be watered moderately, aiming to keep the soil consistently moist without being overly saturated. During the growing season, typically in the spring and summer, water with approximately 1 gallon per week depending on the weather conditions; this amount may need to increase during particularly dry or hot spells. In the fall and winter, reduce the frequency to every other week or when the top inch of soil feels dry to the touch. Avoid letting the plant sit in waterlogged soil as this can lead to root rot. If grown in containers, ensure proper drainage is in place to prevent excess water accumulation.

  • circleLife cycle

    The life of Sarcococca hookeriana 'Winter Gem', commonly known as Sweet Box or Christmas Box, begins with the germination of seeds in moist, well-drained soil, preferably in shaded conditions. As it enters the seedling stage, the plant develops its root system and first leaves. Growth continues through the juvenile phase where the plant increases in size and begins to form its characteristic evergreen foliage. Upon reaching maturity, which may take several years, 'Winter Gem' blooms in late winter to early spring, producing small, fragrant white flowers that are followed by the development of glossy black berries if pollination occurs. The plant's growth slows down once it reaches maturity, but it will continue to produce new leaves and flowers each season. Over time, without significant disturbance, 'Winter Gem' can live for many years, maintaining a compact, bushy habit and providing year-round interest to gardens.

      Late winter-early spring

    • The most popular method to propagate Sarcococca hookeriana 'Winter Gem', commonly known as Sweet Box, is by semi-hardwood cuttings. This process should ideally be done in late summer. One would take a cutting of about 4-6 inches (10-15 centimeters) from new growth that has begun to harden, ensuring a few leaves remain on the cutting. The base of the cutting is dipped in rooting hormone powder to accelerate the development of new roots. Then, the cutting is inserted into a well-draining soil mix, ensuring at least two nodes are buried where the leaves were removed. The cutting should be kept under high humidity with bottom heat if possible, and in a few weeks, it should root successfully, ready to be potted on or eventually planted out once established.
