Light Requirements
Metalasia umbelliformis P.O.Karis prefers to grow in full sunlight. It can tolerate partial shade, but it may become leggy and not flower as abundantly as it would in full sun. Therefore, it is best to plant it in an area of the garden or landscape that receives at least six hours of direct sunlight each day.
Temperature Preference
This plant can tolerate a wide range of temperatures, but it prefers a Mediterranean climate with warm summers and mild winters. It can survive in temperatures as low as 20°F (-6°C) and as high as 100°F (38°C). However, it may not thrive outside of these temperature ranges or in areas with extreme temperature fluctuations.
Soil Requirements
Metalasia umbelliformis P.O.Karis thrives in well-draining soil with a pH between 6.0 and 7.5. It can tolerate slightly acidic or slightly alkaline soil, but it grows best in neutral soil. It is tolerant of poor soil and can grow in sandy, loamy, or clay soil types as long as they are well-draining. However, it is important to avoid wet or waterlogged soil, as this can lead to root rot and other fungal diseases. Adding organic matter, such as compost, to the soil can help improve drainage and nutrient availability for the plant.
Cultivation Methods
Metalasia umbelliformis is a beautiful ornamental plant that is easy to cultivate. It can be grown indoors or outdoors, depending on your preference. When grown indoors, it must be placed in a brightly lit area and away from direct sunlight, while when grown outdoors, it prefers a sunny to semi-shaded location.
The plant requires well-draining soil that is slightly acidic and rich in organic matter. It is essential to ensure that the soil is moist but not waterlogged. The temperature must be maintained between 15-25°C for optimal growth.
Watering Needs
Metalasia umbelliformis requires regular watering, especially during the growing season. The plant must be watered once a week, ensuring that the soil is moist but not waterlogged. It is best to water the plant early in the morning or late in the afternoon to avoid scorching the leaves.
During the winter months, reduce the frequency of watering as the plant is dormant and will not require as much water.
Fertilization
Fertilization is essential for the growth and development of Metalasia umbelliformis. The plant requires regular application of a balanced liquid fertilizer, which should be administered during the growing season.
It is best to apply the fertilizer every two weeks to ensure that the plant receives all the necessary nutrients for optimal growth.
Pruning
Pruning Metalasia umbelliformis is essential to ensure that it remains healthy and robust. The plant must be pruned at the end of the flowering season to promote branching and bushier growth in the next growing season.
To prune, remove the dead and diseased branches, and cut back the long branches to promote bushy growth. You can also pinch back the tips of the branches to encourage branching.
Propagation of Metalasia Umbelliformis
Metalasia umbelliformis can be propagated through various means such as seeds, cuttings, and division.
Propagation through Seeds
Fresh seeds from the plant can be sown in a well-draining soil mixture. Seeds should be planted to a depth of 1-2 cm in the soil. The soil should be kept moist but not wet. The seeds will take approximately 4-6 weeks to germinate. When seedlings are big enough to handle, they can be transplanted to individual pots.
Propagation through Cuttings
Softwood cuttings of the plant can be taken in spring or early summer. Cuttings should be approximately 5 to 10 cm long and should be taken from the tips of healthy stems. Remove the lower leaves and dip cuttings in rooting hormone. Plant the cuttings in well-draining soil mix and keep them moist. Rooting should occur within 4-6 weeks.
Propagation through Division
Metalasia umbelliformis can also be propagated through division. The best time to divide the plant is in spring or early summer when growth is active. Dig up the clump of the plant and gently separate the roots into smaller sections. Each section should have a healthy growth bud. Replant these sections in well-draining soil mix and keep them moist.
