Growth Conditions for Polystachya Pudorina P.J.Cribb
Polystachya pudorina P.J.Cribb, commonly referred to as the Shy Polystachya, is an orchid species that is native to the African continent. Understanding the ideal growth conditions for this plant is crucial to its survival and optimal growth.
Light Requirements
This orchid species requires bright, but indirect light in order to thrive. Exposure to direct sunlight can damage the plant and lead to stunted growth, sunburns, and even death. In its natural habitat, the Polystachya pudorina is usually found in areas where it receives dappled sunlight from the surrounding trees. In addition, it is recommended to provide artificial shade if the natural light in the region is too bright.
Temperature Requirements
The Polystachya pudorina enjoys warm to intermediate temperatures which mimic the tropical temperatures of its natural habitat. The ideal temperature range for this orchid is between 15 and 28 °C. This species is also able to tolerate cooler temperatures that are as low as 10 °C, but not for extended periods of time. This orchid is very sensitive to temperature fluctuations and sudden changes in temperature can cause permanent damage to the plant.
Soil Requirements
Polystachya pudorina should be grown in a well-draining potting mix that is rich in organic matter. A loose mixture of fine bark, perlite, and sphagnum moss would be suitable for its growth. The mixture should be kept moist but not soggy, as the roots of the orchids can easily rot in overly wet soil. The use of a porous pot such as terra cotta is highly recommended as it promotes good drainage and air circulation to the roots of the plant.
Cultivation Methods
Polystachya pudorina P.J.Cribb is an epiphytic orchid that grows naturally on trees in the forests of Africa. To grow this plant, it is necessary to mimic its natural growing conditions. The best way to cultivate Polystachya pudorina is by mounting it on a piece of bark, wood or a tree fern slab.
Before attaching the plant to the mount, ensure that the roots are healthy and not damaged or rotten- remove anything that appears unhealthy. Once removed, fix the plant securely onto the bark with a piece of wire or a plant tie. It should be kept in a bright, indirect light location away from direct sunshine. Overexposure to direct light can cause leaf burns and other damage to the plant.
Watering Needs
Watering is essential for keeping Polystachya pudorina healthy; it should be done with care as the plant cannot tolerate too much moisture. This orchid should be watered regularly, preferably with rainwater or distilled water, but not tap water.
Watering only becomes necessary when the surface of the bark or mount becomes dry. Pour water slowly over the plant until it starts dripping out the bottom. Avoid getting water on the leaves or flowers. The frequency of watering depends on growing conditions, but most importantly, be careful not to let the mount dry completely as it can damage the roots and the plant itself.
Fertilization
Fertilization is a crucial part of cultivating Polystachya pudorina. This orchid requires moderate feeding that should be done every two weeks during the growing season-early spring to late summer. Do not fertilize during the winter season as the plant is usually dormant then. The best type of fertilizer for this plant is a balanced, water-soluble fertilizer mixed to half the recommended strength.
Pruning
Pruning is not required for this plant. However, if the orchid outgrows its available space, remove overgrown stems or roots to allow more room for new growth. Cut off any stems that appear dead, unhealthy, or have excessive damage on them. It is essential to use sterile tools when pruning to avoid damaging the plant and spreading diseases.
Propagation of Polystachya pudorina P.J.Cribb
Polystachya pudorina P.J.Cribb, also known as the shy-flowered Polystachya, can be propagated by various methods.
Division
The plant can be propagated by dividing the old pseudobulbs and planting them in a suitable potting mix. It is important to ensure that each division has at least one healthy pseudobulb and a few roots. The divisions should be planted in small pots with well-draining potting medium, and kept in a warm and humid environment.
Keiki Production
The plant can also produce keikis, which are miniature plantlets that grow on the stem near the base of the leaves. Once the keikis have developed roots, they can be removed and planted in separate pots. It is important to keep the keikis moist and in a humid environment until they are established.
Seed Propagation
The plant can also be propagated by seeds. The seeds should be collected from a mature pod and sown in a well-draining potting mix. The pot should be covered with a plastic wrap and kept in a warm and humid environment. The seedlings should be transplanted to separate pots once they have a few leaves and established roots.
Propagation of Polystachya pudorina P.J.Cribb requires patience and care. With proper attention, the plant can thrive and produce beautiful flowers.
