Light Requirements
Mirabilis hirsuta prefers full sun to partial shade exposure. It grows best when it receives at least 6 hours of direct sunlight per day. The plant can also tolerate some shade, but it might not produce as many flowers as when it is grown in full sun.
Temperature Requirements
The plant is a warm-season annual that thrives in temperatures between 70°F and 85°F. It does not tolerate cold temperatures, and frost can quickly kill it. It grows well in USDA Hardiness Zones 9-10.
Soil Requirements
Mirabilis hirsuta grows well in a well-drained and nutrient-rich soil. The soil should have a pH between 6.0 and 7.5. The plant is not very tolerant to salty soils, and the soil should be free from weeds and other competing plants. Adequate soil moisture is also important for proper growth.
Cultivation Methods
Mirabilis hirsuta is a hardy plant that grows well in full sun or light shade. It is best suited for well-drained soil with a pH range of 6.5 to 7.0. The plant can be propagated through seeds, cuttings, or divisions. During propagation, make sure the soil is moist and the temperatures are warm, ideally around 75°F. Once the plant is established, it requires minimal care.
Watering Needs
Mirabilis hirsuta requires moderate watering. When it comes to watering, it is important to keep the soil moist, but not too wet. During the growing season, water the plant once or twice a week. During the winter season, reduce watering and only water the plant when the soil feels dry to the touch. Make sure the plant has proper drainage to avoid waterlogging.
Fertilization
Mirabilis hirsuta benefits from regular fertilization. Fertilize the plant during the growing season with a balanced fertilizer, such as a 10-10-10 or a 20-20-20. Apply the fertilizer according to the manufacturer's instructions. Avoid over-fertilization, which can lead to excess growth and reduced flowering.
Pruning
Pruning is not required for Mirabilis hirsuta, but it can help to keep the plant healthy and robust. Trim the plant back in early spring before the new growth appears to remove any dead or damaged branches. You can also remove any branches that are crossing or rubbing against each other. Pruning encourages bushy growth and promotes more flowers.
Propagation of Mirabilis hirsuta
Mirabilis hirsuta, commonly known as hairy four o'clock, is a flowering plant that belongs to the Nyctaginaceae family. The plant is native to North America and grows well in well-drained soils. It is a perennial plant with hairy stems and leaves that can reach up to 2 feet in height.
Propagation methods
Mirabilis hirsuta can be propagated by both seeds and stem cuttings.
Propagation by seeds
The seeds of Mirabilis hirsuta are small, black, and have a hard outer covering. They can be collected from the plant when they are mature, usually during the fall. To prepare the seeds for planting, the hard outer covering should be removed by soaking them in warm water for a few hours. Once the outer covering is removed, the seeds can be planted directly in the soil.
It is essential to keep the soil moist and warm to promote germination. The seeds will germinate in about 2-3 weeks. Once the seedlings are large enough, they can be transplanted to their permanent location.
Propagation by stem cuttings
Mirabilis hirsuta can also be propagated by stem cuttings. The best time to take cuttings is during the spring or early summer when the plant is actively growing. To propagate the plant by stem cuttings:
- Take stem cuttings that are about 4-6 inches in length.
- Remove the leaves from the bottom 2 inches of the stem.
- Dip the bottom of the stem into a rooting hormone powder to encourage root growth.
- Plant the stem cutting in a well-draining soil mix.
- Keep the soil moist and warm to promote root growth.
- After a few weeks, the stem cutting should have root growth and can be transplanted to its permanent location.
Mirabilis hirsuta is an easy plant to propagate. With proper care, the plant will thrive and produce beautiful flowers that bloom in the late afternoon.
Disease Management for Mirabilis hirsuta (Pursh) MacM.
Mirabilis hirsuta is generally disease-resistant, but occasionally fungal infections, such as powdery mildew, can occur. Fungal infections tend to thrive in humid climates and can be identified by powdery white spots on the leaves, stem, and flowers. Maintaining good airflow around the plant and ensuring that it is not overwatered can help prevent fungal infections. If a fungal infection does occur, applying neem oil or copper fungicide can help manage the situation.
Pest Management for Mirabilis hirsuta (Pursh) MacM.
Mirabilis hirsuta is also generally pest-resistant, but some insects may be attracted to the plant. Common pests that might affect Mirabilis hirsuta include spider mites, aphids, and whiteflies. Spider mites are tiny and can be identified by the fine webbing they produce on leaves and buds. Aphids and whiteflies are also small and can be identified by their congregations on the undersides of leaves. To manage insect pests, one can apply insecticidal soap, neem oil, or use a small vacuum to carefully remove pests from the plant.
