Growth Conditions for Evolvulus Nummularius (L.) L.
Evolvulus Nummularius (L.) L. is a perennial plant that belongs to the family Convolvulaceae. It is also called blue daze or Hawaiian blue eyes and is native to Brazil. This plant has been widely cultivated in different parts of the world due to its beautiful blue flowers and ease of cultivation.
Light Requirements
Evolvulus Nummularius (L.) L. thrives best in full sun. It requires at least six hours of direct sunlight daily to stimulate healthy growth and vibrant blue flowers. Insufficient sunlight may lead to a lanky plant with weak stems and fewer flowers. In areas with very hot temperatures, partial shade may be necessary to protect the plant.
Temperature Requirements
Evolvulus Nummularius (L.) L. is known for its adaptability to different temperature ranges. It can withstand both high and low temperature conditions. An optimal temperature range for this plant is between 60°F to 80°F. Temperatures above 85°F may cause the plant to go into dormancy, while temperatures below 40°F may result in the death of the plant.
Soil Requirements
Evolvulus Nummularius (L.) L. thrives best in well-draining soil that is rich in organic matter such as compost. The soil pH should be between 6.0 and 7.0. This plant cannot survive in waterlogged soils, so it is necessary to make sure the soil is well-draining. If the soil is poorly drained, it is advisable to grow the plant in raised beds.
Cultivation Methods
Evolvulus nummularius is a low maintenance plant that is easy to cultivate. The plant prefers full sun exposure and well-drained soil for optimal growth. It can grow in a range of soils, including sandy, loamy, and clay soils. It is an adaptable plant that does well in average temperatures and survives harsh conditions, including droughts.
Watering Needs
Evolvulus nummularius is a drought-resistant plant that can withstand long periods without water. However, to encourage better growth and health, it is recommended to water the plant regularly to keep the soil moist but not waterlogged. The frequency of watering may vary depending on the soil type and environmental conditions. In general, it is a good practice to water the plant when the soil feels dry to the touch.
Fertilization
To encourage optimal growth and improve flowering, it is recommended to fertilize Evolvulus nummularius every four to six weeks with a balanced fertilizer. The fertilizer should contain equal amounts of nitrogen, phosphorous, and potassium. Apply the fertilizer around the base of the plant, making sure not to over-fertilize as it may lead to burning the roots and damaging the plant.
Pruning
Evolvulus nummularius is not a plant that requires frequent pruning. However, to maintain its compact shape and encourage better blooming, it is recommended to prune the plant occasionally. Pruning should be done in early spring before the growth season begins. Cut back any dead, diseased, or damaged branches to the nearest healthy growth point. Additionally, trimming the top growth of the plant may encourage bushier growth and produce more flowers.
Propagation of Evolvulus nummularius (L.) L.
Evolvulus nummularius (L.) L., commonly known as Dwarf morning glory, is a beautiful plant that is native to tropical Africa, Asia, and Australia. Propagation of this plant can be done through a variety of methods, including:
Seed propagation
Propagation of Evolvulus nummularius (L.) L. through seeds is one of the easiest and most common methods. Collect the seeds from mature plants in late summer or early fall. Sow the seeds in the soil at a depth of 1/8 inch and apply water gently. Make sure to keep the soil consistently moist during the germination period, which takes about two weeks.
Vegetative propagation
Propagation of Evolvulus nummularius (L.) L. through vegetative means is also possible. This method involves taking cuttings from the mature plants. Cut a 4-inch section of stem just below a node. Strip the leaves from the bottom of the cutting, leaving at least two leaves on the top. Dip the stem into rooting hormone and plant it in a well-draining soil mix. Place it in a shaded area and keep the soil consistently moist.
Division
Division is another method that can be used to propagate Evolvulus nummularius (L.) L. This method involves dividing the mature plant into smaller sections. Dig up the mature plant and divide it into smaller sections, keeping the roots intact. Replant each section in well-draining soil and keep it consistently moist.
Disease Management
Evolvulus nummularius (L.) L. is generally a hardy plant with few disease issues. However, it is not completely immune and some common diseases that might affect it include:
- Leaf Spot Disease: This disease usually presents as yellow or tan spots on the leaves that may eventually turn brown. To manage this disease, it is recommended that any infected parts of the plant be pruned and destroyed, and the plant be treated with copper-based fungicides.
- Root Rot: Root rot disease may occur when the soil is too moist and waterlogged for an extended period. To prevent this disease, ensure that the plant is not overwatered and has adequate drainage. In the event that the plant becomes infected, it is recommended to remove affected parts of the plant and repot it in a fresh potting mix.
Pest Management
Some common pests that might affect Evolvulus nummularius (L.) L. include:
- Mealybugs: These are tiny, white pests that appear as fluffy, cotton-like masses on the leaves of the plant. They can be removed by gently wiping the leaves with a cotton swab dipped in alcohol. Alternatively, insecticidal soaps can be used.
- Aphids: Aphids are small, pear-shaped pests that are often found on the new growth of the plant. They can be removed by spraying the plant with a jet of water or by using insecticidal soaps.
- Spider Mites: These are minuscule pests that form webs on the undersides of the leaves. To control spider mites, increase the humidity around the plant and ensure that it is adequately watered. Insecticidal soaps may also be used.
Regularly inspecting the plant for signs of disease or pest infestations is the best way to prevent serious problems from developing. It is important to address any issues promptly to prevent them from spreading to other plants.
