    The Williamsii Camellia should be watered deeply to ensure the soil is moist but not soggy, typically once a week depending on weather conditions. During the growing season and in drier weather, it may require more frequent watering, possibly twice a week. It's important to water the plant with about 1-1.5 gallons of water each time to ensure the root zone is thoroughly saturated. Reduce watering in the winter when the plant is not actively growing, but do not allow the soil to completely dry out.

  • sunLight

    For the Williamsii Camellia, the ideal light condition is partial shade with some morning sunlight and protection from the hot afternoon sun. The best spot would be in a location where the plant is sheltered from intense midday rays while still receiving sufficient light to encourage healthy growth.

  • thermometerTemperature

    The Williamsii Camellia thrives in temperatures between 60°F and 80°F, which are ideal for growth and flowering. It can survive temporary dips down to around 20°F but should be protected from prolonged exposure to freezing temperatures. Avoid placing the camellia in locations where it could be subjected to extremely hot temperatures, as this can stress the plant.

  • scissorsPruning

    Prune the Williamsii Camellia to maintain its shape and encourage more vigorous growth. Pruning should be done immediately after the blooming season ends, typically in spring, to avoid cutting off next year's buds. Remove any dead or weak branches, and lightly shape the plant as desired to promote a healthier, more aesthetically pleasing structure.

    Williamsii Camellias generally need repotting every 2 to 3 years. It's best to repot in the spring but after the flowering season, using an acidic compost and a pot only slightly larger than the previous one.

  • circleLife cycle

    The Camellia × williamsii 'Hilo' begins its life cycle when a seed germinates, usually in early spring, developing a root system and a shoot that grows upward. As a seedling, it develops true leaves and gradually matures into a small shrub over several years. Once mature, typically after a few years, it begins to flower, usually from late winter to early spring, showing off its colorful blossoms that attract pollinators. After pollination, the flowers produce seed pods that eventually release seeds, completing the reproductive cycle. Throughout its life, which can be quite long—camellias can live for decades—the plant goes through cycles of growth, flowering, and dormancy, typically with a period of dormancy in the winter. With appropriate care, including adequate sunlight, proper watering, and pruning, Camellia × williamsii 'Hilo' continues to grow and bloom annually.

      Spring-Early Summer

    • The Camellia × williamsii 'Hilo', commonly known as a Camellia, can be propagated through semi-hardwood cuttings, typically taken during late summer or early fall when the plant's new growth has started to mature and harden slightly. The most popular method of propagation for Camellias involves taking semi-hardwood cuttings of about 4 to 6 inches in length. Leaves on the lower half of the cutting should be removed, and the cut end can be dipped into a rooting hormone to enhance root development. The cutting is then planted in a pot filled with a well-draining potting mix, such as a mixture of peat and perlite. To maintain high humidity, which is crucial for rooting success, a plastic bag can be placed over the pot or the pot can be kept in a propagator. The cutting should be kept in a warm, shaded place until roots have developed, which can take several weeks to a few months. It's important to avoid direct sunlight and to ensure the potting medium remains moist but not waterlogged throughout the rooting process.
