Hence, it is best to place this plant in a location where it can receive adequate amounts of light without direct exposure to the scorching afternoon sun.
Temperature Requirements
Polystachya subcorymbosa Kraenzl. prefers a warm and humid environment. The ideal temperature range for its growth is between 18-30°C. The plant can tolerate occasional temperature drops to 15°C but cannot survive in freezing temperatures. It is essential to protect the plant from cold drafts and extreme temperature fluctuations.
Soil Requirements
Polystachya subcorymbosa Kraenzl. is an epiphytic plant that grows on the bark of trees in its natural habitat. It prefers a loose, well-draining potting mix with good air circulation. A mix of bark chips, sphagnum moss, and perlite can provide adequate substrate for the plant. The roots of this plant require a humid environment; therefore, it is advisable to water the plant on a regular basis. The use of a clay pot can also help keep the environment humid for the plant.
Cultivation of Polystachya subcorymbosa Kraenzl.
Polystachya subcorymbosa Kraenzl. is a terrestrial orchid that grows in tropical and subtropical areas. It is easy to cultivate and has beautiful flowers that bloom in the spring. The plant prefers medium light and high humidity, with temperatures ranging from 18-29°C.
The plant can be grown in a well-draining medium, such as a mixture of bark, perlite, and sphagnum moss. The plant should be repotted once every two years, or when the potting medium has broken down.
Watering Needs
Polystachya subcorymbosa Kraenzl. requires water to grow, but it is important not to overwater the plant. The soil should be kept moist, but not soggy. The plant should be watered once per week, or when the potting medium feels dry to the touch.
The plant can also benefit from occasional misting to maintain high levels of humidity around the leaves.
Fertilization
Fertilization is important to ensure the plant has the necessary nutrients to grow and bloom. A balanced fertilizer can be applied once per month during the growing season, which is typically from spring through summer.
It is important to follow the fertilizer instructions carefully, as overfertilization can harm the plant. Additionally, the plant should be watered prior to fertilizing to prevent root burn.
Pruning
Polystachya subcorymbosa Kraenzl. does not require much pruning, but dead or yellowing leaves and spent flowers should be removed. This will prevent the plant from wasting energy on dead parts and will also improve the plant's appearance.
When removing spent flowers, it is important to cut them back to the base of the stem, including any attached seed pods. This will encourage the plant to produce new flowers.
Propagation Methods of Polystachya subcorymbosa Kraenzl.
Polystachya subcorymbosa Kraenzl. can be propagated through different methods including:
Division
Division is the easiest method of propagation for Polystachya subcorymbosa Kraenzl. The plant can be divided in early spring when new growth appears. First, remove the plant from the pot and carefully separate the roots. Each division should have several healthy pseudobulbs and a few roots. Plant the divisions in a well-draining potting mix and water thoroughly. Place the plant in a bright, but indirect light location, and keep the soil moist until the roots are established.
Backbulb propagation
Polystachya subcorymbosa Kraenzl. can be propagated from backbulbs or old pseudobulbs. In spring, carefully remove backbulbs from the parent plant and plant them in a well-draining potting mix. Water thoroughly and place the plants in a bright, but indirect light location. Keep the soil moist until new growth appears.
Seed propagation

Common Diseases
Fungal infections: Common fungal infections that might affect the plant include anthracnose, leaf spot, and botrytis. Symptoms include brown spots on leaves, wilting, and discolored stems. To manage fungal infections, remove infected parts of the plant and avoid over-watering. Using a fungicide can also help inhibit the spread of the disease.
Viral infections: Viral infections can make the plant more susceptible to damage from pests while its growth is stunted. Symptoms include a mosaic pattern on leaves. It would be best to remove and destroy infected plants and maintain good hygiene practices. Using virus-free planting materials and practicing proper sanitation can also prevent the spread of viral infections.
Common Pests
Spider Mites: Spider mites are tiny pests that feed on plant juices. Infected plants have a stippled appearance on leaves, and webs may be visible. To manage a spider mite infestation, remove infected parts of the plant and help maintain a high humidity level to reduce the population of spider mites.
Mealybugs: Mealybugs are soft white insects that suck plant sap. Damaged plants have a wilted appearance, small leaves, and stunted growth. To control mealybugs, remove infected parts of the plant, and apply a suitable pesticide or insecticidal soap to control their population growth.
Thrips: Thrips are small, slender insects that cause leaves to appear silvery or scarred. To manage a thrips infestation, remove infected parts and spray the plant with insecticidal soap or a suitable pesticide that will control their growth and development.
In conclusion, Polystachya subcorymbosa Kraenzl. is susceptible to various diseases and pests that can negatively impact its growth and development.
