WaterThe Japanese Camellia, or Camellia japonica 'Mercury', prefers consistently moist soil so it should be watered thoroughly to ensure the soil is damp to a depth of a few inches. As a general rule, water the plant with about 1-2 gallons per week, adjusting for rainfall and the plant's response. During the growing season, especially in hot, dry weather, water might be needed more frequently, possibly every 3-5 days. In winter, reduce watering to prevent root rot but never let the soil completely dry out. A slower, deep watering method is preferable to encourage deep root growth, rather than frequent shallow sprinklings.
LightCamellia japonica 'Mercury' thrives in partial shade or dappled sunlight. It should be planted in a location where it can be protected from the harsh afternoon sun, which can burn the foliage, while still receiving bright morning light or filtered sunlight throughout the day. An eastern or northern exposure often works well, as it provides the requisite light conditions without the intense heat of the afternoon sun.
TemperatureThe Japanese Camellia prefers temperatures ranging from 70 to 85 degrees Fahrenheit during the day and should not be exposed to temperatures below 20 degrees Fahrenheit, as this may cause cold damage. The ideal temperature range for optimal growth and flowering is between 60 and 70 degrees Fahrenheit at night. Protecting it from cold winds and extreme temperature fluctuations will help to maintain its health and vigor.
PruningCamellias, including the Japanese Camellia 'Mercury', should be pruned to maintain shape, remove dead or weak branches, and encourage airflow within the canopy. Pruning is best done immediately after the bloom period ends in late winter or early spring, but before the new vegetative growth begins. Remove no more than one-third of the plant each year to keep it healthy and to avoid shock.
CleaningAs needed
SoilJapanese Camellia 'Mercury' prefers well-draining acidic soil with a pH between 5.5 and 6.5. A recommended mix includes 1 part peat moss or acidic compost, 1 part perlite or vermiculite, and 1 part pine bark fines for optimal growth.
RepottingJapanese Camellias, like the 'Mercury' variety, generally need repotting every two to three years. It is best to repot in late winter or early spring before the growing season begins.
Humidity & MistingJapanese Camellia 'Mercury' thrives in moderate to high humidity levels; ideally between 50% to 80%. Consistent humidity is important for healthy growth and blooming.

Life cycleCamellia japonica 'Mercury', commonly known as the Mercury Camellia, begins its life as a seed, which germinates in moist, well-drained soil with partial shade. After germination, the seedling emerges and establishes itself, developing a robust root system and foliage. As it matures into a young plant, the Mercury Camellia experiences vegetative growth, forming glossy, evergreen leaves and a woody stem structure. Once it reaches maturity, which can take several years, it enters the flowering stage, producing large, showy flowers typically in the winter to spring seasons. These flowers are pollinated by insects, leading to seed formation and dispersal, completing the reproductive cycle. The plant then continues its growth and may produce flowers annually for many years, with a potential lifespan of over a century if growing conditions are optimal.
PropogationPropogation time
Spring-Early Summer
Propogation: Camellia japonica 'Mercury', commonly known as the Japanese camellia, is most popularly propagated by rooting semi-hardwood cuttings. The optimal time for this method is in late summer or early fall, when the current season's growth has begun to mature. To do this, cut a 4 to 6-inch (10 to 15 centimeters) piece of semi-hardwood, strip the leaves from the lower half of the cutting and dip the cut end into a rooting hormone powder. The cutting should then be planted in a well-draining potting mix, ensuring that the leafless portion is buried. The pot then needs to be placed in a warm, humid environment but out of direct sunlight, and kept moist until roots have developed, which can take several months. Once the cuttings have rooted, they can be potted on or planted out into their final positions.
