Water
St. John's Wort should be watered regularly, especially during dry spells, to keep the soil moist but not waterlogged. It's best to provide deep watering when the top inch of soil feels dry, which could be around once weekly, depending on the local climate and weather conditions. Aim for approximately 1 gallon of water per plant each time you water, allowing the moisture to soak deeply into the root zone. During the growing season, you might find the need to water more frequently, while in cooler months, less often. Always check the soil moisture before watering to prevent overwatering, which can lead to root rot.
Light
St. John's Wort thrives in full sun to part shade. The ideal location is a spot where it can receive at least six hours of direct sunlight per day. While it can tolerate some light shade, too much shade can result in fewer flowers and a leggy growth habit. Therefore, positioning this plant in an area with ample morning light and some afternoon shade in hot climates is beneficial.
Temperature
St. John's Wort prefers moderate temperatures and can survive in a range of climates. The plant is hardy and can endure minimum temperatures as low as 0 degrees Fahrenheit, making it suitable for many gardens. It can also tolerate heat well, surviving in temperatures up to 90 degrees Fahrenheit. The ideal range for this plant is between 50 and 70 degrees Fahrenheit to promote healthy growth.
Pruning
St. John's Wort should be pruned to remove dead or damaged branches and to shape the plant. Pruning is best done in early spring before new growth starts. Pruning can also encourage denser growth and more prolific flowering. Annual pruning also helps to rejuvenate the plant and maintain its compact size. Cut back about a third of the oldest stems to ground level to promote new growth.
Cleaning

Life cycle
Hypericum × hidcoteense 'Hidcote', commonly known as St. John's Wort 'Hidcote', begins its life cycle as a seed, typically requiring stratification to break dormancy. Once germinated, seedlings establish roots and shoots in spring, growing rapidly and forming a bushy, woody perennial structure. Throughout the summer, the plant enters its flowering stage, producing abundant star-shaped yellow flowers, which are attractive to pollinators and often lead to seed production if pollination occurs. After the blooming period, seeds mature by late summer or fall and are dispersed through various mechanisms, including animal activity and gravity. As temperatures cool and daylight shortens in autumn, the plant enters a period of dormancy, reducing growth and conserving energy. The cycle repeats when warmer temperatures and longer days in spring stimulate new growth, and the plant can also spread through vegetative means, such as cuttings or division.
Propogation
Propogation time
Summer
The most popular method of propagating Hypericum × hidcoteense 'Hidcote', commonly known as the Hidcote St. John's Wort, is through semi-ripe wood cuttings. This process is generally done in the late summer months. To propagate, one takes semi-ripe cuttings with several nodes present, typically reaching 4 to 6 inches (around 10 to 15 centimeters) in length, from the current year's growth. The lower leaves are stripped off, and the cut end can be dipped in rooting hormone to encourage root development. These cuttings are then inserted into a mix of peat and perlite or sand to provide good drainage and aeration, with the container being kept in a warm environment with indirect light. The soil should be kept moist but not wet, and, with proper care, roots will develop in several weeks, allowing the new plants to be gradually acclimated to outdoor conditions before being planted out in the garden the following spring.
