Light Requirements
Mirabilis gausapoides is a plant that requires a lot of sunlight. It is most suitable for growing in areas where it can receive direct sunlight for at least six hours a day. If grown in the shade, the plant will grow slowly and produce fewer flowers.
Temperature Requirements
The plant grows well in tropical and subtropical climates where the temperature ranges between 20-30°C. It is sensitive to frost and cannot tolerate temperatures below 10°C, which can cause the plant to wilt and die.
Soil Requirements
The soil must be well-draining and fertile. It should have a neutral to slightly acidic pH (6.0-7.5). Loamy soil with a mix of sand, silt, and clay is best suited for the plant's growth. It can also grow in poor soil conditions, but this will affect the quality and quantity of the plant's growth.
Cultivation Methods
Mirabilis gausapoides (Standl.) Standl., commonly known as the Guatemalan Four O'Clock, is a perennial plant that thrives in tropical environments. It prefers well-draining soil with a slightly acidic to neutral pH value. The plant requires full sun exposure, but it can tolerate some partial shade. In areas with colder climates, it is recommended to grow the plant indoors or in a greenhouse during the winter months to avoid frost damage.
Watering Needs
Mirabilis gausapoides (Standl.) Standl. requires frequent watering during the growing season. The soil should be kept moist but not waterlogged. During the winter months or in areas with low humidity, the plant's watering needs should be reduced to avoid root rot. Checking the moisture level at the base of the plant using a moisture meter is recommended. Additionally, the plant benefits from occasional misting to increase humidity levels.
Fertilization
The Guatemalan Four O'Clock benefits from regular fertilization during the growing season. A balanced fertilizer rich in nitrogen, phosphorus, and potassium promotes healthy growth and blooming. Fertilizer can be applied every two weeks or as directed on the product label. Avoid over-fertilization, as it can cause damage to the plant's roots and negatively affect its growth.
Pruning
Pruning Mirabilis gausapoides (Standl.) Standl. is recommended to control the plant's growth and shape. The plant can be pruned during the growing season to remove any dead or damaged stems, leaves, or flowers. Pruning can also stimulate the growth of new shoots and blooms. The plant's upper foliage should be trimmed to prevent it from becoming too tall and lanky. Additionally, removing spent flowers can increase the longevity of the plant's bloom period. To avoid damage to the plant, use clean and sharp pruning shears.
Propagation of Mirabilis gausapoides
Mirabilis gausapoides (Standl.) Standl. can be propagated through different methods such as seed propagation, vegetative propagation, and cuttings.
Seed Propagation
Propagation through seed can be done by collecting the matured pods around the month of December. After harvesting, the pods should be allowed to dry out and then crushed to extract the seeds. The extracted seeds should be cleaned and then soaked in water for about 24 hours before sowing in a well-drained sandy soil mixture. The sowing should be done during early spring. The seeds usually take around 2 to 3 weeks to germinate.
Vegetative Propagation
Varieties of Mirabilis gausapoides can be propagated through vegetative propagation. The stem fragments usually take around 2 to 4 weeks to root. For successful propagation, the stem cutting should be taken from healthy and disease-free plants.
Cuttings Propagation
Cuttings of branch tips can also be propagated by taking a 4-6 inch long cutting from the plant. It should then be pinched off the bottom leaves and should be stuck in rooting hormone powder. The cuttings will root within 3-6 weeks.
Disease and Pest Management for Mirabilis Gausapoides (Standl.) Standl.
Mirabilis gausapoides (Standl.) Standl. is a type of flowering plant that belongs to the Nyctaginaceae family. Like any other plant, it is susceptible to disease-causing organisms and pests that can affect its growth and development. Below are the common diseases and pests that may attack this plant and the ways to manage them.
Diseases
Root Rot: This is a fungal disease that affects Mirabilis gausapoides roots, causing them to rot. The infected plant may show yellow leaves, wilting, and stunted growth. Overwatering and poor drainage are the main factors that trigger root rot. To manage the disease, avoid overwatering, improve drainage, and remove infected plants from the garden to prevent the spread of the fungus.
Powdery Mildew: Powdery mildew is a fungal disease that appears as a white powdery substance on the leaf surface. It occurs in humid environments or when the foliage is excessively watered. The infected leaves may curl and become distorted, and the plant may experience stunted growth. To manage powdery mildew, maintain proper spacing between the plants, avoid overhead watering, and apply a fungicide labeled for powdery mildew.
Leaf Spot: Leaf spot is a fungal disease that affects the leaves of Mirabilis gausapoides. The disease manifests as circular spots on the leaves, which later develop a brownish-black color. The infected leaves may fall off, leading to defoliation and stunted growth. To manage leaf spot, remove the infected leaves from the plant or use a fungicide labeled for leaf spot management.
Pests
Aphids: Aphids are small insects that attack the leaves of Mirabilis gausapoides and suck the sap out of them. The plant may show yellowing leaves, stunted growth, and deformed leaves. To manage aphids, wash the plant with water to remove them, use insecticidal soaps or neem oil, and introduce natural predators such as ladybugs.
Cutworms: Cutworms are larvae of moths that feed on the stems of Mirabilis gausapoides and cut them off at the base. The plant may show wilting and stunted growth, and the cutworms may hide in the soil during the daytime. To manage cutworms, handpick them at night when they are active, use biological control such as Steinernema carpocapsae nematodes, or apply insecticides labeled for cutworm management.
Spider Mites: Spider mites are tiny arachnids that feed on the undersides of Mirabilis gausapoides leaves, causing them to turn yellow and drop off. The plant may experience stunted growth and produce a fine web-like substance on the foliage. To manage spider mites, spray the plant with water to dislodge them, use insecticides labeled for spider mite management or introduce natural predators such as predatory mites.
By following the above steps, you will be able to manage most of the diseases and pests that attack Mirabilis gausapoides and ensure that the plant thrives and remains healthy.
