Genus that includes 15-20 species of epiphytic orchids, originating from the humid forests of central-southern America. They do not possess pseudobulbs, they are fan-shaped rosettes of long arched, narrow and thin leaves, light green in color, quite rough and covered by a deep central vein; in late autumn and in winter at the base of the leaves, at the apex of short thin stems, large single white flowers bloom, with pink, blue or purple veins or spots, sometimes with a contrasting color lip; there are numerous hybrids, often of very bright colors, spotted with white. The petals are fleshy, waxy and thick, sometimes shiny; these flowers give off a delicate fragrance. The pescatorea have quite easy cultivation and are also suitable for beginners.
To best cultivate your pescatorea orchids, place the pots in a very bright place, but away from the direct rays of the sun which could cause burns on the leaves and compromise the development of the plant; these orchids fear the cold, and need average temperatures close to 18-20 ° C, which is why in winter they should be kept indoors, away from cold currents or frost, or in a temperate greenhouse where the ideal habitat is created for their cultivation.
Water regularly for the duration of the year, intensifying the watering in the summer months, usually warmer and drier, still allowing the substratum to dry a little between one watering and another; every 2-3 days vaporize the leaves with demineralized water, to increase the environmental humidity. From March to November provide specific fertilizer for orchids, mixed with the water of the watering, every 10-15 days.
Use a compound for epiphytic orchids, consisting of pieces of bark, polystyrene and vegetable fibers; repot at least every two years, to allow the plants to develop harmoniously. It is important to remember that the choice of land must be made taking into account the specific needs of our orchid; in fact, each plant needs a particular soil to develop and grow at its best. From the ground our plants acquire the main nutrients they need to live; hence the importance of this element.
The multiplication of the pescatorea orchid usually occurs by dividing the clumps of leaves, leaving a vigorous and well developed root at each obtained portion; new plants are immediately repotted in a single container; in general the divisions are practiced in late spring.
Pescatorea: Pests and diseases
As for diseases and pests that could attack the plant, it is important to pay attention to scale insects. These are tiny parasites which, feeding on the sap contained in the orchid leaves, weaken the entire plant. For manual removal of scale insects, use an alcohol swab; if the problem is widespread and not limited, prefer specific pesticide products.
A further problem that can present the pescatorea, is the presence of root rot. So pay attention to watering: let the soil dry between one irrigation and another.
