Light Requirements
Evolvulus glaber Spreng. requires full to partial sunlight for optimal growth. It is recommended to place the plant in a location that receives at least six hours of direct sunlight per day. Excess shade can lead to poor growth and fewer flowers.
Temperature Requirements
Evolvulus glaber Spreng. thrives in warm to hot temperatures. The ideal temperature range for this plant is between 20-30°C (68-86°F). Temperatures outside this range can affect plant growth and flowering. It is important to protect the plant from sudden temperature changes.
Soil Requirements
Evolvulus glaber Spreng. prefers well-draining, sandy loam soil with a pH range of 5.5-7.5. The soil should be rich in organic matter and should not retain excess water. A mix of compost and sand can be added to the soil to improve drainage. It is important to avoid heavy soil or soil that is prone to waterlogging.
Cultivation Methods
Evolvulus glaber Spreng. is a hardy perennial plant that thrives in tropical regions. It requires well-draining soil that is moist and rich in humus. The plant prefers full sun exposure and thrives in temperatures between 60 and 85 °F. The seedlings should be planted four to six inches apart in rows that are 12 to 18 inches apart.
Watering Needs
Evolvulus glaber Spreng. needs regular watering to thrive. The soil should be kept moist, but not waterlogged. Water the plant deeply once or twice a week, depending on the weather and the soil type. If the soil is sandy, the plant may require more frequent watering. Avoid overwatering, as it can cause root rot and stunted growth.
Fertilization
Evolvulus glaber Spreng. benefits from regular fertilization to promote healthy growth and blooming. Use a balanced fertilizer with equal amounts of nitrogen, phosphorus, and potassium. Apply the fertilizer once every two weeks during the growing season. Avoid fertilizing the plant during the dormant season.
Pruning
Evolvulus glaber Spreng. requires minimal pruning, as it has a compact growth habit. However, it is advisable to trim off the dead and diseased branches to enhance the plant's appearance and health. Additionally, pruning can promote the growth of lateral branches and more flowers. Prune the plant in early spring before the active growth phase.
Propagation of Evolvulus glaber Spreng.
Evolvulus glaber Spreng., commonly known as Dwarf Morning Glory, is a perennial herb found widely in Central and South America. Propagation of Evolvulus glaber is typically done through seed, but it can also be propagated from stem cuttings.
Seed Propagation
Seeds of Evolvulus glaber can be easily collected from the plants after flowering. The seeds should be sown in well-drained soil, and it is best to plant them during the rainy season. The seeds should be sown at a depth of 1-2 cm and should be watered gently. The seeds usually germinate within 10-15 days and should be thinned out once the seedlings have a few true leaves.
Stem Cutting Propagation
Propagation of Evolvulus glaber can also be done through stem cuttings. To propagate through stem cuttings, select a healthy stem that is approximately 6-8 inches in length and has no flowers. Cut the stem just below a node, and remove all the leaves from the lower half of the stem. Dip the cut end of the stem in rooting hormone and plant it in a well-draining soil mix. Water the cutting well and place it in a warm, humid location. The cutting should root within 2-3 weeks and can be transplanted to a larger container after a few months.
