Temperature Requirements
Eulophia pusilla Rolfe is a warm-growing plant that thrives in temperatures between 20°C-30°C (68°F-86°F). Sudden temperature changes may harm the plant, so ensure that it is placed in an area with stable temperatures. Avoid placing the plant in drafty areas or near air conditioning units.
Soil Requirements
The ideal soil for Eulophia pusilla Rolfe should have a slightly acidic to neutral pH between 6.0-7.0. The soil should be well-draining and rich in organic matter, such as leaf mold and peat moss. The plant prefers sandy or loamy soil that is capable of mimicking its native habitat. Ensure that the soil is kept moist but not waterlogged to prevent root rot.
Cultivation of Eulophia pusilla Rolfe
Eulophia pusilla Rolfe is a native terrestrial orchid of the tropical West Africa region. The orchid's natural habitat is the forest floor where it receives shade from the overhead canopy, and the soil is well-drained loam with abundant organic matter. In cultivation, Eulophia pusilla Rolfe prefers a well-drained potting mix with good aeration that mimics its natural habitat.
Watering Needs
Watering Eulophia pusilla Rolfe is a balance, and the frequency of watering depends on the potting mix, humidity, temperature, and season. Overwatering is detrimental to the plant as it results in rotted roots and death. It's essential to ensure the potting mix is almost dry before watering. Eulophia pusilla Rolfe also appreciates high humidity levels, and misting is a good way to increase moisture levels without overwatering the plant.
Fertilization
Eulophia pusilla Rolfe requires minimal fertilization, and an orchid specific 20-20-20 fertilizer can be applied once a month during the growing season (spring to fall). In the winter, the plant is dormant, and fertilization is not necessary.
Pruning
Eulophia pusilla Rolfe requires minimal pruning, and it's essential to let the plant go through its natural growth cycle. The plant develops new shoots and leaves in the growing season and becomes dormant in the winter. If necessary, pruning of dead or diseased stems can be done at any time of the year.
Propagation of Eulophia pusilla Rolfe
Eulophia pusilla Rolfe is a terrestrial orchid that is native to Southeast Asia. It is commonly known as the "dwarf Eulophia" due to its small size, and it is a prized ornamental plant for its beautiful flowers. Propagation of Eulophia pusilla Rolfe can be done using two main methods: seed propagation and division.
Seed Propagation
Seed propagation is a popular way to propagate Eulophia pusilla Rolfe. The seed pods of the plant mature in late summer to early fall, and the seeds can be sown immediately after they are harvested. It is important to sow the seeds in a well-draining medium and to keep them moist during the germination period. The ideal temperature for germination is around 20 to 25°C.
The seedlings can be transplanted into individual pots when they are large enough to handle. It is important to maintain a humid environment and to avoid direct sunlight during the early stages of growth. Once the plants are established, they can be grown under normal conditions and will flower in around two to three years.
Division
Division is another way to propagate Eulophia pusilla Rolfe. This method involves dividing the rhizomes of the plant to create smaller plantlets. The best time to divide the plant is during the dormant period, which is usually in late fall or early winter.
To divide the plant, carefully remove it from its container and gently separate the rhizomes. Each division should have several healthy pseudobulbs and a good root system. Plant each division in a well-draining medium and water thoroughly.
It is important to avoid overwatering during the early stages of growth, as this can cause rotting. Once the roots are established, the plant can be grown under normal conditions and will flower in around two to three years.
Both seed propagation and division are effective ways to propagate Eulophia pusilla Rolfe. With proper care and attention, these plants will produce beautiful flowers to enjoy for years to come.
