Rose of Sharon requires moderate watering, especially during dry spells. It's best to water deeply once a week, providing about 1-2 gallons per plant, depending on the size and weather conditions. Always allow the soil to dry out slightly between waterings to prevent root rot. Water the plant at the base to avoid wetting the foliage, which can lead to fungal diseases. In hot, dry conditions, you may need to water more frequently, but overwatering can be as harmful as under-watering.
Rose of Sharon thrives in full sun to partial shade. For optimal growth and bloom, plant it in a location where it can receive at least six hours of direct sunlight each day. While it can tolerate some light shade, too much shade may reduce flowering and cause the plant to become leggy as it reaches for more light.
Rose of Sharon is hardy and can withstand a range of temperatures, typically thriving in regions with temperatures between 60°F to 90°F. It can survive winter cold down to about -20°F but may need protection in zones with colder extremes. The ideal growing conditions for Rose of Sharon include warm, temperate climates where it can receive plenty of sunlight and heat.
Prune Rose of Sharon to maintain shape and encourage next season's blooms, as it flowers on new wood. Prune in late winter or early spring before new growth begins. This is also a good time to remove any dead, damaged, or crossing branches. Typically, pruning once per year is sufficient, but you can also prune lightly after the flowering period to shape the plant or control its size.

- Life cycle
The Rose of Sharon 'Diana' begins its life cycle when a seed germinates, typically in spring, after experiencing a period of cold stratification to break dormancy. The seedling stage follows, where the plant develops its first true leaves and establishes a basic root system. As it enters the vegetative stage, the plant grows rapidly, producing stems, leaves, and branches, which allows it to photosynthesize more efficiently and garner resources for blooming. Flowering occurs in the summer to early fall, where 'Diana' boasts large white flowers that are attractive to pollinators, leading to cross-pollination if there are viable mates nearby. After pollination, the plant sets seeds enclosed in capsules, which mature and are eventually dispersed to close the reproduction cycle. The Rose of Sharon 'Diana' is a perennial shrub, repeating this cycle each year while gradually increasing in size and capacity to produce more flowers and seeds.
The Rose of Sharon 'Diana' can be propagated through softwood cuttings taken in late spring or early summer. To propagate by cuttings, a healthy stem tip about 5 to 6 inches (roughly 12.7 to 15.2 centimeters) long is selected. Leaves are removed from the lower half of the cutting, and the cut end is dipped in a rooting hormone to enhance root development. The cutting is then placed in a well-draining potting mix, with the leafless portion buried. It's important to maintain a humid environment for the cutting by covering it with a plastic bag or placing it in a propagator, but one should ensure that the plastic doesn't touch the leaves to prevent fungal issues. The pot is kept in a bright, indirect light location until roots develop, usually within a few weeks, after which it can be gradually acclimatized to outdoor conditions.
