Water
The Rose of Sharon requires watering deeply, ensuring that the water reaches the plant's roots, rather than just wetting the surface. During the growing season, water the plant once a week with about 1 to 1.5 gallons of water, depending on weather conditions like heat and wind that may increase the need for water. If rainfall is adequate, additional watering may not be necessary. It's crucial to reduce watering in the fall to prepare the plant for winter. Always check the soil moisture by feeling it a few inches deep; if it feels dry, it's time to water again.
Light
Rose of Sharon thrives best in full sun conditions, meaning it requires at least 6 to 8 hours of direct sunlight each day to perform optimally. Place it in a spot where it can receive unfiltered sunlight for most of the day. However, the plant can tolerate partial shade, especially in regions with very hot summers, where some afternoon shade can prevent overheating.
Temperature
The Rose of Sharon is hardy and can tolerate a wide range of temperatures. It can survive in temperatures as low as 20°F and high as 90°F, but it grows best in temperatures between 60°F and 80°F. Sudden frosts or extreme heat can damage the plant, so protection may be necessary if these conditions are expected.
Pruning
Prune the Rose of Sharon in late winter or early spring before new growth starts. Pruning helps to shape the plant, encourage bushier growth, and remove any dead or damaged branches. It should be done annually, but light pruning can be performed throughout the year as needed. The best time for heavy pruning is when the plant is dormant to minimize stress and maximize the upcoming season's bloom.
Cleaning
As needed
Soil
Rose of Sharon benefits from a well-draining, loamy soil with good organic content. The ideal pH range for Rose of Sharon 'Ruby Glow' is slightly acidic to neutral (pH 6.0 to 7.5). A mix of two parts loam, one part peat moss, and one part perlite or sand is recommended to ensure proper drainage and aeration.
Repotting
Rose of Sharon 'Ruby Glow' typically does not require frequent repotting, as it is often grown as a large shrub or small tree outdoors. However, if grown in containers, repotting every 2-3 years, or when the plant becomes root-bound, is advised to refresh the soil and provide additional space for growth.
Humidity & Misting
Rose of Sharon prefers moderate humidity levels but is quite adaptable to different humidity conditions. Strive for around 50-60% relative humidity for optimal growth if growing indoors.
Suitable locations
- Indoor
  Ensure bright, indirect light and consistent watering.
- Outdoor
  Place in full sun, protect from strong winds.
- Hardiness zone
  5-9 USDA
Life cycle
The life cycle of the Hibiscus sinosyriacus 'Ruby Glow', commonly known as Rose of Sharon 'Ruby Glow', begins with seed germination when temperatures become favorable in spring. Seedlings emerge and grow into young plants, developing characteristic three-lobed leaves and woody stems. As the shrub matures, it enters a stage of vegetative growth, where it focuses on leaf production and increasing its overall size. Upon reaching maturity, typically within a few years, 'Ruby Glow' begins its reproductive phase, producing deep ruby-red flowers with prominent stamens during late summer, attracting pollinators for sexual reproduction. After pollination, the flowers develop into seed pods, which eventually dry and release seeds in autumn, completing the cycle. Throughout its life, the plant undergoes periods of dormancy in winter, where growth ceases temporarily, resuming with warmer weather in spring.
Propogation
- Propogation time
  Spring to early summer
- Hibiscus sinosyriacus 'Ruby Glow', commonly known as Rose of Sharon, can be propagated through several methods, but the most popular is via stem cuttings. To propagate by cuttings, one should ideally take a 4 to 6-inch (10 to 15 cm) long stem from a healthy, mature plant during late spring or early summer. This stem should have several leaves but the lower leaves should be removed before planting. The base of the cutting is then dipped in rooting hormone to encourage root growth and planted in a well-draining potting mix. The cutting should be kept moist and in a warm spot with indirect light until roots have developed, which usually takes several weeks. Once the cuttings have rooted, they can be transplanted into the garden or larger pots for further growth.
