Temperature Requirements
This plant thrives in warm temperatures, with a preferred range of 60-85°F (15-30°C). It is tolerant of high temperatures but is prone to frost damage in extremely low temperatures. It is best to protect the plant during cold months.
Soil Requirements
The preferred soil of Hypericum turgidum Small is well-draining, slightly acidic soil that is rich in organic matter. It grows successfully in various types of soil, including loam, clay, and sandy soil, as long as the soil is well-draining. It is essential to keep the soil consistently moist, but it should never become waterlogged. Adding a layer of mulch around the base of the plant can help retain moisture and suppress weed growth.
Cultivation Methods
Hypericum turgidum, commonly known as Turgid-Stemmed St. John's Wort, is a hardy plant that is easy to grow. It thrives best in well-drained soil and prefers full sun exposure. It is recommended that you plant it in the autumn or spring when the soil is moist and not too cold. The plant is propagated through seeds, stem cuttings, or division of clumps.
Watering Needs
Watering your Turgid-Stemmed St. John's Wort regularly is important, but overwatering can cause root rot. It is best to water it deeply once a week or when the top two inches of soil are dry. Avoid overwatering the plant during the winter months when it is dormant.
Fertilization
Fertilizing your Turgid-Stemmed St. John's Wort once a year is enough to promote its growth and keep it healthy. Use a balanced fertilizer with equal amounts of nitrogen, phosphorus, and potassium. Apply it in the spring before new growth appears, but make sure to follow the instructions on the package to avoid over-fertilization.
Pruning
Pruning is not necessary for Turgid-Stemmed St. John's Wort, but it can promote bushier growth and a more compact shape. You can prune the plant in the early spring before new growth appears or in the late fall after the plant has gone dormant. To promote healthy growth, remove any dead or damaged branches and cut back any overgrown branches.
Propagation of Hypericum turgidum Small
Hypericum turgidum Small, also known as the Blue Ridge St. John's Wort, can be propagated through both sexual and asexual means.
Sexual Propagation
The plant produces small yellow flowers in the summer, followed by a capsule containing multiple seeds. To propagate through sexual means, collect the mature seeds in the fall and plant them in well-draining soil in a sunny location the following spring. Cover the seeds with a thin layer of soil and keep the soil moist but not waterlogged. The seeds will germinate in a few weeks to a few months.
Asexual Propagation
Hypericum turgidum Small can also be propagated asexually through stem cuttings or layering.
To propagate through stem cuttings, take a cutting from a healthy plant during the growing season, ideally in the spring or summer. Select a stem that is at least 4 inches long and has several leaves. Remove the lower leaves and dip the cut end into rooting hormone. Plant the cutting in well-draining soil and keep the soil moist but not waterlogged. The cutting should root in a few weeks to a few months.
To propagate through layering, select a long, flexible stem and bend it down to the ground. Make a shallow cut on the stem where it touches the ground and cover the cut with soil. Weigh down the stem with a rock or other heavy object. Keep the soil moist but not waterlogged. The stem will root in a few weeks to a few months, and can then be separated from the parent plant and transplanted.
