Soil requirements
Mirabilis aspera Greene prefers well-draining soils, rich in organic matter. The plant can tolerate various soil types, including sandy, loam, and clay soils, as long as the drainage is good. It prefers a slightly acidic soil pH range of 6.0 to 6.5.
Cultivation Methods
The plant Mirabilis aspera Greene can be cultivated either by seeds or cuttings. The seeds must be soaked in water overnight before planting. Once the soil temperature reaches 60°F, plant the seeds in a hole that is 4-6 inches deep. Cover and water well. Cuttings can be taken during the summer season and should be planted in soil mixed with sand and peat moss to increase water drainage. Place the pot in a shaded area and keep the soil moist until the roots have formed.
Watering Needs
The plant can tolerate drought conditions but requires regular watering every 7-10 days for optimal growth. Allow the soil to dry out a bit before watering. Ensure that the soil has proper water drainage to avoid waterlogging and root rot. A layer of mulch can help retain moisture in the soil and reduce the frequency of watering. Water the plant deeply once a week during the dry season.
Fertilization
Mirabilis aspera Greene requires a moderate amount of fertilizing. Apply a balanced fertilizer with equal amounts of nitrogen, phosphorus, and potassium (NPK) during the growing season every 4-6 weeks. The plant can also benefit from organic fertilizers such as compost tea or fish emulsion. Avoid over fertilizing as it can lead to poor growth, weaker stems, and burnt leaves.
Pruning
Pruning is necessary for maintaining the plant's shape and size. It is recommended to prune Mirabilis aspera Greene during late winter or early spring. Remove the dead or diseased stems and branches, and cut back any overgrown or straggly branches. Use clean and sharp pruning tools to avoid damaging the stems. Light pruning can be done during the summer to promote bushier and fuller growth.
Propagation of Mirabilis aspera Greene
Mirabilis aspera Greene, commonly known as “hairy umbrellawort” or “roughflower”, is a herbaceous plant that can grow up to 3 feet tall. It is known for its attractive flowers that bloom during the evening hours, and its leaves that possess medicinal qualities. If you are planning to propagate this plant, you must know that it can be propagated easily through seeds, cuttings, or division.
Propagation through Seeds
The easiest and most common method of propagating Mirabilis aspera Greene is through seeds. The seeds can be collected from the dried up flowers of the plant. Collect the seeds and sow them in pots or directly in the soil during late spring or early summer. The soil should be well-drained and moist. Cover the seeds with a thin layer of soil and keep them in a warm and sunny location. The seeds should germinate within 10-15 days.
Propagation through Cuttings
Propagation through cuttings is also a viable method for Mirabilis aspera Greene. Choose a healthy and disease-free branch from the plant and cut it at an angle of 45 degrees. Remove the lower leaves from the cutting and dip the cut end in a rooting hormone. Plant the cutting in a pot or directly in the soil. Keep the soil moist and well-drained, and place the pot in a warm and sunny location. Within a few weeks, the cutting will start to root and grow.
Propagation through Division
Mirabilis aspera Greene can also be propagated through division. This method involves separating the roots of an established plant into smaller sections and replanting them individually. To do this, carefully dig up the plant and separate the roots into sections, ensuring that each section has at least one stem and a good amount of roots. Replant the sections in pots or directly in the soil. Keep the soil moist and well-drained, and place the pots/ new plants in a warm and sunny location.

Pests
Mirabilis aspera is resistant to most pests, but it can still be affected by the following insects:
- Spider Mites - These pests are tiny and can be hard to spot until they cause significant damage to the plant. They suck the sap from the leaves, causing the plants to become yellow and wilted. To manage this pest, spray the plant with insecticidal soap or neem oil.
- Whiteflies - These pests suck the sap from the leaves, causing them to become yellow and wilted. They also leave behind a sticky residue called honeydew, which can attract ants and other pests. Use a yellow sticky trap to manage this pest.
By following proper disease and pest management practices, you can maintain the health and beauty of your Mirabilis aspera Greene plant for years to come.
