Fertilizers rich in nitrogen, potassium, and phosphorus can also be added to improve the soil quality and encourage the plant's growth.
Cultivation methods for Eulophia keniensis Schltr.
Eulophia keniensis Schltr. can be grown both indoors and outdoors, depending on the climatic conditions of the area. It thrives in well-draining soil, preferably sandy loam or clayey loam that holds moisture well. The plant needs partial shade to full sun exposure for healthy growth.
Avoid planting the Eulophia keniensis Schltr. in low-lying areas prone to waterlogging since it can lead to root rot. The plant prefers a warm and humid climate with temperatures ranging between 21°C to 26°C.
Watering needs for Eulophia keniensis Schltr.
Watering the Eulophia keniensis Schltr. plant is determined by several factors, including the climatic conditions, soil type, and growth stage. Water the plant when the top inch of soil is dry. Overwatering the plant leads to root rot, and underwatering leads to dryness and stunted growth.
During the growth stage, water the plant consistently, ensuring that the soil is moist at all times. However, during dormant periods, reduce watering the plant to avoid excess water retention in the soil.
Fertilizing Eulophia keniensis Schltr.
Eulophia keniensis Schltr. responds well to regular feeding with a balanced fertilizer. Apply the fertilizer every two weeks during the growing season. A slow-release fertilizer with all necessary nutrients is recommended.
For newly planted Eulophia keniensis Schltr., apply a balanced fertilizer with a higher nitrogen concentration to promote root and shoot growth.
Pruning Eulophia keniensis Schltr.
Pruning Eulophia keniensis Schltr. is necessary for the removal of dead, damaged, or diseased leaves and stems. Remove the affected parts of the plant immediately to prevent the spread of diseases to the healthy parts.
Remove the spent flowers to promote the development of new blooms. Ensure that you use clean and sterilized pruning shears to prevent the transfer of infections to the plant.
Propagation of Eulophia keniensis Schltr.
Eulophia keniensis Schltr., commonly known as the Kenyan Eulophia, is a terrestrial orchid species found in East Africa, particularly in Kenya and Tanzania. Propagation of this plant can be done through two main methods:
1. Division
Division is the easiest and most common method of propagating Eulophia keniensis. The plant can be divided when it outgrows its container or when it produces several pseudobulbs. The best time to divide the plant is during the dormant period, which is usually in early spring.
To divide the plant, carefully remove it from its container and gently shake off the soil from its roots. Using a sharp and disinfected knife, cut the rhizome into sections, making sure that each section has a healthy pseudobulb, at least two eyes, and several roots. Dust the cuts with a fungicide and leave them to dry for about an hour before planting them in separate containers filled with well-draining potting mix.
2. Seed
Propagation of Eulophia keniensis can also be done through seed. However, this method is a bit complicated and requires patience. The seeds of this plant do not have endosperms, so they need mycorrhizal fungi in the soil to germinate and grow.
To propagate the plant through seed, sterilize a container and fill it with a mixture of well-draining potting mix, peat moss, and vermiculite. Sow the seeds on top of this mixture, pressing them gently onto the surface, and then sprinkle a layer of mycorrhizal fungi on top of them.
Cover the container with a plastic bag or a lid and keep it in a warm and shaded place, away from direct sunlight. The seeds may take several months to germinate, and you may not see any growth for a while. Once the plantlets emerge, gradually remove the cover and transfer them to separate containers filled with a similar mixture of potting mix, peat moss, and vermiculite.
In summary, propagation of Eulophia keniensis can be done through division and seed. Division is the easiest and most common method, while seed propagation requires patience and specific conditions to succeed.
