Orchids how to cure them

Orchids, a huge variety of species and families

The orchid family is very large, there are more than 775 species and they are widespread almost everywhere, mostly in the wetlands of the tropical zone. In Italy we have about 85 species that live in the wetlands of the mountains and on the coasts, some rare and in danger of extinction. Their habitat depends on whether they are epiphytes, that is, they have aerial roots, so they live on the trunks of other plants or on rocks, or if they are terrestrial, such as those widespread in temperate climates, then there are other aquatic ones. Orchids are the most commercialized flowers in the world because of the spectacular beauty of their flowers, they are sold mostly as cut flowers, however there are some species with particular ornamental value that are grown in special vases, giving a suggestive tone to the home environment. .

Lighting, habitat and irrigation

In nature, orchids live in a humid hot tropical climate, so to grow your orchids in a healthy way they must be placed near the windows, in a position that is not exposed to direct sunlight. Furthermore, it is advisable to place them where there are no drafts and direct sources of heat, such as radiators or stoves. Furthermore, it is absolutely necessary to avoid placing them in poorly lit areas of the house, because otherwise they will not bloom and in the worst case the leaves could fall off the stem. Orchids do not water like classic garden plants, orchids need very little water, because due to their nature, excess water could cause damage. There are two methods for watering orchids: the first is to use the nebulizer, spraying the water directly on the plant; in the second case, only if the orchid is small in size, it is necessary to place the orchid in a perforated pot and immerse it in a basin of water at room temperature in a bain-marie until the soil becomes moist. that the surface soil is dry.

Orchids, soil, repotting fertilizer and pruning

The orchid, being an epiphytic plant, needs a particular soil, the so-called substrate, composed of a very soft soil to which pieces of bark, coconut fiber and peat are added. The most used is the bark, composed of spruce and Douglas fir bark, which can be purchased from any nursery. Fertilization should be done every fortnight, using special fertilizers for orchids. Of course, very little water must be used for fertilization, spraying it on the plant. When the substrate begins to become compact and poorly draining, it means that it is losing its nutritional value and it is necessary to repot. To do this you need to get a vase slightly larger than the previous one, arrange a bottom of cork, or polystyrene, then the plant must be placed in the pot and covered with the new substrate, to which expanded polystyrene must be added to ensure proper drainage. Pruning should only be done when necessary, while it is necessary to eliminate dry leaves and stems daily using sterilized gardening scissors, to avoid plant contagion.

Orchids how to cure them: Many orchids, here are the most common on the market

Although the orchid comes from a tropical climate, thanks to its great adaptability it has become one of the most widespread plants in the world. The most common orchids on the market are: – Cymbidium orchid: not very suitable to be kept indoors, because it does not always manage to bloom and is subject to parasitic attacks. It is advisable to place it in balconies and gardens and use nitrogen-based fertilizers. -Orchid Dendrobium: it is an orchid with characteristic purple flowers, it is an evergreen provided that it is subjected to nebulizations at least once a month throughout the year and that it is kept in an environment with a constant level of humidity. -Phalaenopsis orchid: this is the home orchid par excellence, in fact it needs twenty degrees during the day and fifteen at night. It is subject to the phenomenon of stagnation, therefore it must be nebulized only if the soil is dry and a particularly draining soil must be used. It is also subject to the growth of multiple flowers on the same stem so it must be pruned frequently. -Orchid Vanda: its habitat is hot and humid therefore in the hot months it needs frequent nebulizations, if well cared for it guarantees fiuriture all year round.
