The plant blooms from July to September. The Mirabilis linearis (Pursh) Heimerl var. subhispida Heimerl plant species prefers dry habitats and is often found in sandy or rocky soils.Light Requirements
Mirabilis linearis (Pursh) Heimerl var. subhispida Heimerl prefers full sun to partial shade for optimal growth. The plant requires at least six hours of sunlight per day to thrive. Inadequate sunlight may lead to stunted growth and poor development of flowers.
Temperature Requirements
This species of Mirabilis can tolerate a wide range of temperatures. However, it grows best in temperatures ranging from 65-80 degrees Fahrenheit. The plant is not hardy and does not tolerate low temperatures. Temperatures below 50 degrees Fahrenheit can cause severe damage to the plant.
Soil Requirements
The ideal soil for Mirabilis linearis (Pursh) Heimerl var. subhispida Heimerl is a well-draining, sandy loam with a pH of 6.5-7.5. The plant can also grow in a range of soil types, including loamy or clay soils, as long as they are not waterlogged. The soil should be rich in nutrients such as nitrogen, phosphorus, and potassium, which are essential for the growth and development of the plant.
Cultivation Methods
Mirabilis linearis (Pursh) Heimerl var. subhispida Heimerl requires well-drained soil with a pH range of 5.5 to 7.5. The plant prefers full sunlight for optimal growth. It can be propagated from seeds or stem cuttings. Sow the seeds in early spring, and keep the soil evenly moist. For stem cuttings, take 10-15cm cuttings, dip the cut end in rooting hormone, and plant in a potting mix. Keep the soil moist and warm, and the cutting should root in about four weeks.
Watering Needs
Mirabilis linearis (Pursh) Heimerl var. subhispida Heimerl needs regular watering in the growing season to keep the soil moist but not waterlogged. Water deeply about once a week or when the top inch of soil feels dry. Reduce watering during the dormant season to avoid overwatering, which can lead to root rot or fungal infection.
Fertilization
Mirabilis linearis (Pursh) Heimerl var. subhispida Heimerl benefits from fertilization to support growth and flowering. Use a balanced fertilizer with an N-P-K ratio of 10-10-10. Apply the fertilizer every four weeks during the growing season. Follow the package instructions for application rates, or dilute the fertilizer to half strength to avoid over-fertilization.
Pruning
Mirabilis linearis (Pursh) Heimerl var. subhispida Heimerl does not require pruning, but it benefits from deadheading to promote blooming. Cut off the spent flowers as soon as they fade to prevent the plant from wasting energy on seed production. You can also prune the plant to shape or control its size after it finishes blooming in the fall. Use clean, sharp pruning shears to avoid damaging the plant.
Propagation Methods for Mirabilis Linearis Var. Subhispida
Mirabilis linearis var. subhispida, commonly known as narrowleaf four o'clock, is a herbaceous perennial plant that belongs to the Nyctaginaceae family. Propagation of this plant can be done through seeds, stem cuttings or division of rhizomes.
Propagation through Seeds
Propagation through seeds can be done during the fall season or indoors under controlled conditions. The seeds should be scarified before sowing to increase their chances of germination. To scarify the seeds, they should be rubbed with sandpaper or filed lightly to break the hard outer covering.
Once the seeds are scarified, they should be sown in well-draining, fertile soil and lightly covered with soil. The germination process usually takes 2-3 weeks, after which the seedlings should be transplanted to larger containers or into the ground.
Propagation through Stem Cuttings
Propagation through stem cuttings is the easiest and fastest method of propagating Mirabilis linearis var. subhispida. The ideal time to take stem cuttings is during the spring or early summer when the plant is actively growing.
Using sterilized pruning shears, cut a 4-6 inch section of stem that has a few leaves attached. Remove the bottom leaves and dip the cut end of the stem in rooting hormone to stimulate root growth. Plant the stem cutting in well-draining soil and keep it moist until roots start to form. Transplant the rooted stem cutting to a larger container or into the ground.
Propagation through Division of Rhizomes
Propagation through division of rhizomes is best done during the fall season when the plant is dormant. Dig up the clump of plants and separate the rhizomes with a sterilized knife or garden fork. Each rhizome should have at least one healthy shoot and root system.
Transplant the individual rhizomes to a well-draining, fertile soil and water them thoroughly. Water the newly transplanted rhizomes regularly to establish their root systems.
By following these propagation methods, propagating Mirabilis linearis var. subhispida will be an easy and rewarding experience.
Disease Management
Like all plants, Mirabilis linearis (Pursh) Heimerl var. subhispida Heimerl is susceptible to various diseases, especially when conditions are favorable for their growth. The following are some of the common diseases that may affect this plant and methods of managing them:
Leaf spot
Leaf spot is a fungal disease that attacks the leaves of the plant, leaving them with dark spots that eventually become holes. To manage this disease, use a fungicide specifically designed for leaf spot. Also, remove and destroy any infected leaves and avoid watering the foliage since high humidity provides an ideal environment for the disease.
Root rot
Root rot is caused by a fungus that grows in poorly drained soils, leading to the decay of the plant’s roots. To manage this disease, ensure that you plant in well-drained soils and avoid overwatering the plant. In severe cases, use a fungicide designed for root rot.
Pest Management
Just like diseases, pests also pose a significant threat to the growth and development of Mirabilis linearis (Pursh) Heimerl var. subhispida Heimerl. The following are some of the common pests that might attack this plant and methods of managing them:
Spider mites
Spider mites are tiny arachnids that suck sap from the leaves of the plant, leading to stunted growth and yellowing leaves. To manage this pest, keep the plant foliage clean and free of dust and debris since spider mites thrive in dusty environments. Also, apply a miticide designed to kill spider mites.
Aphids
Aphids are small, pear-shaped insects that congregate on the undersides of leaves and suck sap from the plant, causing distorted growth and yellowing leaves. To manage aphids, blast them off the plant with a strong stream of water or use insecticidal soap or neem oil.
