The plant can be grown outdoors in USDA hardiness zones 10 to 11.
Soil Requirements
Eulophia involuta Summerh. thrives in well-draining soil that is rich in organic matter. A good potting mix should consist of equal parts of perlite, peat moss, and orchid bark. Avoid using heavy, clay-like soils that retain moisture as they can lead to root rot. It is recommended to repot the plant every 2 years using fresh potting mix.
Cultivation of Eulophia involuta Summerh
Eulophia involuta Summerh. is a terrestrial orchid that grows naturally in the tropical and subtropical regions of Africa. This plant requires specific care and attention to thrive, but with some effort, it can bloom beautifully. Here is a guide for cultivating Eulophia involuta Summerh.
Watering Needs
Eulophia involuta Summerh. needs consistent and regular watering. However, it's crucial to avoid overwatering as this can damage the roots. Water the plant once every week during the growing season, and reduce the frequency to once every two weeks during the dormant season. Ensure that the soil is well-draining, and avoid waterlogging.
Fertilization
Fertilization is essential for the growth of Eulophia involuta Summerh. Use a balanced fertilizer during the growing season to promote healthy growth. It's advisable to fertilize the plant monthly or bi-monthly using a diluted solution. Avoid over-fertilization as this can burn the roots and damage the plant.
Pruning
Pruning is a crucial aspect of caring for Eulophia involuta Summerh. Remove the old or withered leaves as they can become a breeding ground for pests and diseases. Remove the spent or faded flowers to encourage the growth of new ones. When pruning, be careful not to damage the stems or roots.
Propagation of Eulophia involuta Summerh.
Eulophia involuta Summerh. can be propagated through various methods. Some of the popular propagation methods are described below:
Seed propagation
Seeds are an excellent way to propagate Eulophia involuta Summerh. Collect matured seed pods from the mother plant when they start to turn brown or black. The seeds should be sown in a well-draining soil mix that is high in organic matter. Cover the seeds with a thin layer of soil and keep the soil moist. The seeds should germinate within 2-3 weeks.
Division
Division is another popular method of propagating Eulophia involuta Summerh. This method involves separating the rhizomes from the main plant and replanting them in a separate location. This method is best done during spring when the new growth starts to emerge. Carefully dig up the plant and separate the rhizomes with a sharp, sterilized knife. Make sure that each section of the rhizome has multiple healthy shoots and roots attached. Plant each section in a new pot or directly into the ground.
Cuttings
Eulophia involuta Summerh. can also be propagated through stem cuttings. Take a cutting from the stem of the plant with a sharp, sterilized knife. The cutting should be about 4-6 inches long and have at least two nodes. Remove the lower leaves from the cutting and plant it in a well-draining soil mix. Keep the soil moist and keep the cutting in a warm and humid environment. The cutting should root within 4-6 weeks.
Eulophia involuta Summerh. is a beautiful and exotic plant that is easy to propagate through various methods. With proper care and attention, you can easily grow this plant in your garden and enjoy its beauty for years to come.
