  • water dropWater

    The Rose of Sharon should be watered deeply to encourage root growth, which typically equates to about 1 inch of water per week. During the first growing season, it's important to maintain an even moisture level to establish a robust root system. Watering should be done either early in the morning or late in the afternoon to minimize water loss due to evaporation. In hot and dry conditions, you may need to water twice a week, whereas in cooler weather or if your soil retains moisture well, watering once a week might suffice. When watering, apply water directly to the soil rather than overhead to avoid wetting the foliage, which can lead to disease.

  • sunLight

    Rose of Sharon thrives best in full sun, meaning it should receive at least six to eight hours of direct sunlight each day. Choose a planting spot that is free from shadows for most of the day to ensure the plant gets enough light. Though it can tolerate partial shade, flowering is most abundant when the plant is placed in an area with ample sunlight.

During the growing season, maintaining temperatures within its preferred range encourages robust growth and flowering.

    Pruning the Rose of Sharon is essential to maintain its shape, encourage bushier growth, and promote more prolific blooming. The best time to prune is late winter or early spring before new growth begins. Remove any dead or damaged wood, and thin out crowded branches to improve air circulation. Pruning can be done annually, but be mindful to only remove about one-third of the plant material in a single session to avoid causing stress to the plant.

  • circleLife cycle

    Hibiscus syriacus 'Sup'Heart', commonly known as Rose of Sharon or Shrubby Althea, starts its life as a seed, which germinates in spring under the right moisture and temperature conditions. After germination, the seedling develops into a young plant, growing leaves and roots. As it matures, the plant enters a vegetative stage, during which it develops a woody stem and a robust root system. It reaches maturity in a few years, when it begins to produce its characteristic large, trumpet-shaped flowers, usually in summer to fall. Reproductive maturity continues annually, where the plant blooms, and the flowers are pollinated, leading to the production of seeds. In winter, the plant goes dormant, shedding its leaves in colder climates, and then resumes its growth cycle with the return of warm weather in spring.

      Spring-Early Summer

    • The most popular method of propagating the Hibiscus syriacus Sup'Heart, commonly known as Rose of Sharon, is through softwood cuttings. This technique is usually done in late spring to early summer when new growth is still flexible and not yet mature. Cuttings about 4 to 6 inches long are taken from healthy branches, making sure each cutting has several leaf nodes. The bottom leaves of the cuttings are removed and the cut end is dipped in rooting hormone to enhance root development. The treated cuttings are then planted in a mix of peat and perlite or sand, ensuring at least one leaf node is below the surface. The containers are kept in a warm, well-lit area but out of direct sunlight, and the medium is kept moist until roots have developed, which typically takes 4 to 6 weeks.
