Light Requirements
Eulophia robusta Schltr. typically requires a moderate to high amount of light to grow properly. Direct sunlight is well-tolerated but it is best to provide some shade during the hottest part of the day to prevent the plant from drying out. A shaded environment with dappled sunlight is ideal.
Temperature Requirements
Eulophia robusta Schltr. is a tropical plant that thrives in warm to hot temperatures. Optimal growth is achieved in temperatures ranging from 70 to 90°F (21°C to 32°C). It is important to note that this plant cannot tolerate frost or cold temperatures and will not survive in temperatures below 50°F (10°C).
Soil Requirements
Eulophia robusta Schltr. typically prefers well-draining soil that is rich in organic matter. The soil should be slightly acidic with a pH ranging from 5.5 to 6.5. It is important to avoid compacted soil as it can impede root growth and cause the plant to wither. In terms of moisture, the plant requires consistent watering to avoid dry soil, but excess water should be avoided as it can cause root rot.
Cultivation Methods
Eulophia robusta Schltr. is an epiphytic orchid species known for its beautiful flowers and ease of cultivation. The plant is native to Madagascar, where it grows on mossy rocks and trees in humid forests. To cultivate this orchid successfully, you need to provide a proper growing environment that mimics its natural habitat. The plant prefers a warm, humid, and shady environment and needs free air circulation.
You can grow Eulophia robusta Schltr. in pots or baskets, or you can attach it to a piece of cork, bark, or slabs. Whatever media you choose, make sure it is well-drained and holds moisture effectively. You can use a mix of bark, coconut husk chips, and perlite as a growing medium.
Watering Needs
Eulophia robusta Schltr. prefers consistent moisture but does not like to be waterlogged. Water the plant when the top layer of the medium is dry to the touch. In general, you will need to water once or twice a week. During hot and dry periods, you can increase the frequency of watering.
When watering, use filtered or rainwater and avoid using cold water. Water the plant thoroughly, soaking the medium and roots, and then let the excess water drain out. Avoid leaving stagnant water in the pot, as this can lead to root rot.
Fertilization
To promote healthy growth and blooming, you can fertilize Eulophia robusta Schltr. using a balanced orchid fertilizer. You can use a 20-20-20 or 30-10-10 fertilizer, applied every two weeks during the growing season (spring and summer). Reduce the frequency of feeding during the winter months, as the plant is dormant.
When fertilizing, dilute the fertilizer to half-strength and apply it when you water the plant. Avoid fertilizing a dry plant, as this can burn the roots.
Pruning
Eulophia robusta Schltr. does not require any pruning, but you can remove dead or yellowing leaves and flowers to keep the plant looking tidy. If the plant has outgrown its pot, you can repot it in a larger one during the spring when new growth appears. When repotting, remove any dead or rotted roots and replace the medium.
Be careful not to damage the roots when repotting, as this can cause stress and slow down growth. After repotting, reduce watering for about two weeks to allow the roots to adjust to the new environment.
Propagation of Eulophia robusta Schltr.
Eulophia robusta Schltr., commonly known as the Robust Eulophia, is a terrestrial orchid species found in India, Sri Lanka, and Southeast Asia. Propagation of the Robust Eulophia is typically done through two methods:
Seed Propagation
Seed propagation is the most common and preferred method used for propagating Eulophia robusta. The seeds should be collected from mature plants when they are dark brown or black in color, indicating maturity. Then, the seeds should be soaked in water for 24 hours and then sown in a pot containing a well-drained medium. The pot should be kept in a shaded area, and the medium should be kept moist. New growth should emerge in approximately 20-30 days.
Division Propagation
Division propagation is another method used for propagating Eulophia robusta. This method is done through separating the pseudobulbs of the plant. The plant should be dug up, and the pseudobulbs can be separated with a sharp, sterile knife. Each pseudobulb should have at least two healthy roots and a leaf. Then, the pseudobulbs should be planted in a well-draining medium in individual pots. The pots should be kept in a shaded area and the medium should be kept moist. New growth should emerge in approximately 6-8 weeks.
It is important to note that Eulophia robusta is a slow-growing plant, and it may take several years for the plant to reach maturity and bloom.
