When grown indoors, the plant should be placed near the brightest window in the room, and supplemental fluorescent lighting may be used to ensure adequate light levels.
Temperature Requirements
Emilia coccinea is a tropical plant that requires warm temperatures between 20°C and 30°C (68°F to 86°F). Temperatures below 13°C (55°F) can cause the plant to suffer, and frost can be fatal to it. Therefore, it should be grown in warm climates outdoors, or in temperature-controlled environments indoors.
Soil Requirements
Emilia coccinea prefers soil that is well-draining and slightly acidic with a pH of 5.5 to 6.5. It grows best in loamy, rich soil that is fertile and high in organic matter. The plant can tolerate mildly saline soil, but it struggles to grow in heavy clay soil. The soil should be kept moist but not waterlogged to prevent root rot and other fungal diseases.
Cultivation of Emilia coccinea auct.
Emilia coccinea auct. is a warm-season annual plant that requires a sunny location and well-draining soil to thrive. The plant can grow up to 2 feet tall and 1 foot wide, and it blooms from mid-summer until the first frost.
Watering Needs
Emilia coccinea auct. requires consistent watering to maintain healthy growth during the growing season. Watering should be done regularly to keep the soil moist but not waterlogged. It is best to allow the soil to dry slightly between watering to prevent root rot.
Fertilization
Emilia coccinea auct. benefits from regular fertilization throughout the growing season to promote healthy growth and prolonged blooming. A slow-release fertilizer with a balanced nutrient ratio, such as 10-10-10 or 20-20-20, will work well for this plant. The fertilizer should be applied according to the instructions on the package.
Pruning
Pruning can help maintain the shape and size of Emilia coccinea auct. while also encouraging prolonged blooming. Deadheading the spent blooms regularly can prevent the plant from going to seed too quickly. Trimming back the plant by one-third of its height in mid-summer will encourage bushier growth and more blooms.
Propagation of Emilia coccinea auct.
Emilia coccinea auct. can be easily propagated by seeds, stem cuttings, and division of root clumps.
Propagation by Seeds
Seeds of Emilia coccinea auct. can be sown directly into the soil or started indoors in pots. The seeds should be planted at a depth of 1 cm and kept slightly moist until germination occurs. It is recommended to sow the seeds in the spring or summer for best results.
Propagation by Stem Cuttings
Stem cuttings can be taken from the parent plant during the spring or summer months. The stem cuttings should be around 6 inches long and taken from healthy, mature plants. Remove the leaves from the lower half of the cutting and dip it in rooting hormone powder. Plant the cutting into a well-draining soil mixture, keep it moist and place it in a warm, bright location until roots start to develop.
Propagation by Division of Root Clumps
For propagating through division, dig up the plant in the spring or fall and divide the root clumps into smaller sections using a sharp, sterilized knife. Each section should have a few stems and roots attached. Replant the sections in the prepared soil mixture and water generously. Keep the soil slightly moist until the plant is established.
