Renanthera Imschootiana Information 

Renanthera imschootiana, commonly known as Red Vanda Flower, is a species of orchid native to Southeast Asia, including countries such as Thailand, Malaysia, and Indonesia. It is a highly prized orchid for its bright red flowers that are large and showy, with a distinctive shape that resembles a bird in flight. 

The Red Vanda Flower is an epiphytic orchid, meaning it grows on the surface of other plants, usually trees. Additionally, it has a monopodial growth habit, which means that it grows from a single stem and produces leaves and flowers from the top of the stem. Red Vanda Flower is a relatively easy-to-grow orchid that can be a great addition to any orchid collection, as well as a stunning ornamental plant for any home or garden.

Finally, place the plants in a warm, bright location and monitor their progress, checking for rot or pest infestations.

Requirements to Grow Red Vanda Flower

Red Vanda Flower requires bright, indirect sunlight to thrive. It prefers to grow in partial shade, such as under a tree canopy or on a shaded balcony.

The plant can tolerate some direct sunlight, but it should be protected from harsh midday sun and extreme heat. In general, the Red Vanda Flower needs around 4 to 6 hours of bright, indirect sunlight per day to support healthy growth and flowering. 


Red Vanda Flower is an epiphytic orchid, meaning it does not grow in soil, but instead grows on the surface of other plants, such as trees, and absorbs nutrients and moisture from the air and surrounding environment.

As a result, it does not require traditional soil for growth, but instead requires a well-draining growing medium that mimics the natural conditions of its epiphytic habitat. 


Renanthera Imschootiana orchids require frequent watering, typically every 2-3 days, especially during hot and dry weather conditions. They need a well-draining potting mix that retains some moisture but does not stay wet. It is important to water the orchid early in the morning, allowing time for the leaves and roots to dry before nightfall. 


Red Vanda Flower thrives in warm to hot temperatures, between 20-35°C (68-95°F). These orchids prefer a temperature drop of around 5-10°C (41-50°F) at night.

They require good air circulation and humidity levels of around 60-80% to prevent drying out of the leaves and roots.

Red Vanda Flower Care



Red Vanda or Renanthera Imschootiana orchids require a balanced fertilizer with equal amounts of nitrogen, phosphorus, and potassium (NPK) every 2-3 weeks during the growing season (spring and summer).

Use a high-quality orchid fertilizer that contains micronutrients, such as iron, magnesium, and calcium. Dilute the fertilizer according to the instructions on the package and apply it to the soil or substrate around the roots, avoiding direct contact with the leaves or flowers. 


Prune dead or yellowing leaves, stems, or roots of Red Vanda Flower using sterilized pruning shears to prevent the spread of diseases. Remove spent flowers by cutting the stem just above the node where the flower grew to promote new growth and flowering. 

Pest and Disease Care  

Red Vanda Flowers are susceptible to pests such as mealybugs, scale insects, spider mites, and thrips. Inspect the orchid regularly for signs of infestation, such as sticky residue, webbing, or distorted leaves.

Treat pests using a targeted insecticide, such as neem oil, insecticidal soap, or rubbing alcohol, following the instructions on the product label. 

Renanthera Imschootiana orchids can also suffer from diseases such as bacterial or fungal infections, root rot, and leaf spot. Avoid overwatering, overcrowding, or using contaminated soil or water that can spread diseases. I

f you notice any signs of disease, remove the affected Red Vanda Flowers parts and treat the orchid using a fungicide or bactericide, following the instructions on the product label.
