Light Requirements
Mirabilis bigelovii Gray var. bigelovii requires full sun exposure for proper growth and development. They thrive in areas that receive at least six hours of direct sunlight every day. Lack of adequate sunlight can lead to weak stems, stunted growth, and poor flowering. Hence, it is essential to plant these flowers in a location with plenty of natural light.
Temperature
This plant species is native to the hot desert regions of the southwestern United States and northern Mexico. It can tolerate high temperatures ranging from 90 to 100 degrees Fahrenheit. However, it is also important to note that they require a cooler period to establish roots and ultimately flourish. Cooler months, between 50-60 degrees Fahrenheit, are suitable for germination and initial growth. As they mature, and before the heat of summer sets in, expect the plant to grow larger and set flowers.
Soil Requirements
The Mirabilis bigelovii Gray var. bigelovii prefers well-drained soils that are sandy, gravelly, or rocky in nature. They grow best in soils with a pH ranging from neutral to slightly alkaline. The plant has a shallow root system, and the soil should not be too compact, ensuring that the roots can spread out comfortably. Organic matter, such as compost, can be added to the soil to improve drainage, soil texture, and nutrient content. It is necessary to avoid overwatering, which can lead to root rot and other soil-related issues.
Cultivation
Mirabilis bigelovii Gray var. bigelovii, also known as Bigelow's desert four o'clock, is a drought-tolerant perennial that is native to the southwestern United States and northern Mexico. It grows well in full sun and can tolerate a range of soil types. To cultivate this plant, make sure it is planted in well-draining soil that is not too rich in organic matter. pH levels of 6.0 to 7.5 are ideal. Plant the seeds in the early spring or late fall to ensure that they have enough time to become established before extreme heat sets in.
Watering Needs
Mirabilis bigelovii Gray var. bigelovii requires minimal watering. It is a drought-tolerant plant that prefers to stay on the dry side. Water only when the soil is completely dry, and avoid getting water on the foliage, as this can cause the plant to rot. During the peak of summer, irrigation may be necessary once every two weeks, but it is essential not to overwater the plant.
Fertilization
Mirabilis bigelovii Gray var. bigelovii is a low-maintenance plant that does not require a significant amount of fertilizer. It has a slow growth rate, and the use of fertilizers should be minimal. Use a balanced fertilizer, such as a 10-10-10 blend, every spring to help the plant generate new growth. Avoid over-fertilizing, as this can cause the plant to produce an abundance of foliage and fewer flowers.
Pruning
Mirabilis bigelovii Gray var. bigelovii does not need to be pruned often. The plant is self-supporting and will not require staking. However, to encourage bushier growth and more flowers, pinch back the tips of the stems periodically during the growing season. This will stimulate the plant to produce more lateral shoots and more blossoms. Pruning should be done in the early spring before new growth emerges.
Propagation of Mirabilis bigelovii Gray var. bigelovii
Mirabilis bigelovii Gray var. bigelovii, commonly known as Bigelow's desert four o'clock or Colorado four o'clock, is a herbaceous plant native to North America. It is a member of the Nyctaginaceae family and can grow up to 60 cm tall.
Propagation by Seeds
The easiest and most common way to propagate Mirabilis bigelovii Gray var. bigelovii is by using seeds. The plant produces small, black seeds that can be collected from the flowers after they have withered. To increase the chances of successful propagation, it is best to harvest the seeds when they are fully mature and dry. Once you have collected the seeds, you can either start them indoors early or sow them directly into the soil where you want the plant to grow.
Propagation by Cuttings
Propagation by cuttings is also possible for Mirabilis bigelovii Gray var. bigelovii, although it may take longer to establish compared to the propagation by seeds. Cuttings can be taken in the summer when the plant is actively growing. Select healthy stems, cut them at a 45-degree angle, and remove the leaves from the bottom 2/3 of the stem. Dip the cut end of the stem into rooting hormone powder and plant it in moist, well-draining soil. Keep the soil moist and place the cutting in a shaded area until you see new growth, which indicates that rooting has occurred.
Propagation by Division
Mirabilis bigelovii Gray var. bigelovii can also be propagated by division. This method can be used to rejuvenate old plants or to create new plants from an existing one. It is best to divide the plant during the spring or early summer when it is actively growing. Dig up the plant and gently separate the roots into smaller sections using a clean and sharp knife. Each section should have a healthy root system and at least one stem. Plant the sections in well-draining soil and water them thoroughly.
Overall, Mirabilis bigelovii Gray var. bigelovii is a relatively easy plant to propagate, and you can choose the method that works best for you depending on your situation and preferences.

Common Diseases
Powdery Mildew: Powdery mildew is a fungal disease that affects the leaves of the four o'clock plant, causing the formation of powdery white or gray spots. It is caused by high humidity or poor ventilation. To manage this disease, remove the affected leaves, improve ventilation, and use fungicides.
Verticillium Wilt: Verticillium wilt is a fungal disease that causes the wilting of leaves and stems of the four o'clock plant. It is caused by soil-borne fungi that infect the roots of the plant. To manage this disease, remove the infected plant and avoid planting in infected soil.
Root Rot: Root rot is a fungal disease that affects the roots of the four o'clock plant, causing them to turn brown or black and become soft and mushy. It is caused by over-watering or poorly drained soil. To manage this disease, improve soil drainage, reduce watering, and use fungicides.
Common Pests
Spider Mites: Spider mites are tiny pests that feed on the leaves of the four o'clock plant, causing yellowing and wilting. They thrive in hot, dry conditions. To manage these pests, increase humidity around the plant, use insecticidal soap, or introduce natural predators like ladybugs.
Thrips: Thrips are small, slender insects that feed on the leaves and flowers of the four o'clock plant, causing a distorted appearance. They also transmit viruses that can cause plant diseases. To manage these pests, use insecticidal soap or predatory insects like lacewings.
Aphids: Aphids are small, soft-bodied insects that feed on the sap of the four o'clock plant. They secrete a sticky substance that attracts ants and can spread plant viruses. To manage these pests, use insecticidal soap or introduce natural predators like ladybugs.
By proper management of diseases and pests, one can ensure a healthy growth of the Mirabilis bigelovii Gray var. bigelovii plant to decorate their garden.
