They are in fact very suitable plants even for those who are beginners or have the so-called black thumb (if this were your case, here is a perfect article for you).

In the next few lines you will find out everything there is to know about orchids. Let's begin!

The main characteristics of orchids

The orchids they are monocotyledonous plants of the order of Orchidales which can be found everywhere except in glaciers and deserts. Furthermore, they can be of two different types:

  • autotrophic, that is, able to use its aerial roots to absorb all the necessary nutrients from the water present in the surrounding environment
  • saprophytes, that is, able to obtain its nourishment from decaying organisms

Orchids are among the most popular flowers in the world

Orchids are gods perennial herbaceous plants, whose flowers have a rather recognizable structure: three upper sepals and three lower petals; one of these petals, called by the name of labellum, is different from the others as regards its shape, very particular and necessary to attract pollinating insects. It is also important to remember that the orchid flower twists 180 degrees at the time of development.

As for the leaves, these have a linear structure which can be tubular or fleshy. At their base you may find pseudobulbs, which function as reserve assimilators.

As for the roots, these can be, as we have seen, of two different types based on the type of orchid, that is, they can be in an aerial position or in the ground.

The aerial roots they appear covered by a layer formed by dead cells full of air, which performs a protective function and is the cause of their typical whitish color.

The underground root system, on the other hand, it is characterized by rounded rhizotubers, or by the presence of rhizomes or, again, by coralliform roots.

Orchids: care and exposure

Orchid care begins with them exposure. In fact, these plants love sunlight, but not excessively direct. We therefore recommend that you keep it indoors, in one bright room e, possibly, in front of a window.

As for the temperature, orchids do not like excessively low temperatures nor temperature changes. So make sure to place it in a place in the house, balcony or garden protected from the wind and where it is temperature remain more or less between 17 ° C and 24 ° C. The higher temperatures, say around 35 ° C, can only be tolerated by orchids in the presence of good ventilation and plenty of shade.

Caring for orchids is easy, but it requires attention and dedication

In addition, orchids thrive in the presence of a good rate humidity. A bowl of water placed near your plant will serve exactly this purpose. Alternatively, the vase containing the orchid can be placed inside a larger vase which will have on the bottom water and expanded clay. By doing so, the evaporation will keep the humidity level constant, but the water will not come into contact with the roots, eliminating the risk of root rot.

What soil for your orchids?

Orchids, for proper care, must grow in right ground. The latter must have three main characteristics:

  • allow the water to drain quickly
  • allow one good air circulation
  • provide the roots with a certain solidity to cling to

For these reasons the spruce bark substrate it is the most suitable for this type of cultivation.

Orchids: care and watering

Irrigation, you know, it can be one of the most complicated aspects of plant care and orchids are no exception. As a general rule orchids need to keep a moist substrate, but not too much.

Here are our tips for best watering this plant:

  • during the summer months, water the orchid three or four times a week
  • during the winter months you can reduce watering to once a week

Remember that with plants such as orchids it would still be better to run out of water rather than overdoing the water supply.

Always use rainwater or demineralized water, both of which are chlorine-free.

What other crop treatments?

There fertilization it is not a mandatory practice when it comes to orchids and their care, however we recommend that you do it every two weeks or so. The ideal fertilizer is specific for orchids and it is essential to never let it come into contact with the leaves. We have explored the subject in this article.

Finally, the vase. It would be preferable to use a transparent vase, so as to be able to more easily monitor the development of the roots and the onset of any problems.

Orchids cultivation and care

How is orchid grown? What are the diseases and parasites that attack it and what are the defenses and treatments?

Let's discover together the secrets of the elegant queen of flowers for the home: theOrchid.

His racemes produce splendid flowers, very durable, which beautify the home with their elegant design and their exotic beauty.

The epidendrum they are orchids native to South America and have about 400 different species. Most of these are orchids epiphytes that is, plants that grow on trees. However, there are many species terricolous and others that develop on rocks. The latter grow exclusively in Central and South America and since they cannot grow in a place other than their habitat, cultivation in our country is not possible.

The varieties that can be grown in Italy, and that we can find in nurseries, are about ten. These have no pseudobulbs and come with drums long and erect, similar to reeds. From these develop i flowers, smaller than those of the most common orchids. These inflorescences are very elegant and with various colors such as red, orange, yellow, purple, pink, white and green. The leaves they are ribbon-like or lanceolate and bright green in color.

Epidendrum orchids are grown by virtue of theirs decorative skills compared to other varieties they are able to bloom for several months. In fact, the flowers, after having withered, give way to other inflorescences. When this happens, it is good practice to remove the withered flowers with sharp and disinfected shears.



They propagate both for cutting, both for root division.


Epidendrums appreciate very bright environments, but the direct rays of the sun must be avoided as they can create problems for the plant.

In the vegetative rest phase, that is, during the winter, it is necessary to provide the plant with a habitat with a temperature not exceeding 15 ° C.


These orchids grow well in universal potting soil, even better when mixed with sphagnum is pieces of bark. This care allows you to maintain the right level of humidity to make the plant grow in health.


It is good to avoid too abundant watering, but it should be borne in mind that these plants are also very afraid of drought. For this reason it is necessary to provide constant but moderate irrigation. Failure to comply with this rule can cause shriveling of the leaves and subsequent fall.

In principle, irrigation must be provided when the soil is dry. Watering is usually done once a week in hot weather and once every 15 days in winter.

We also recommend spray water at room temperature on the leaves to recreate the humid habitat essential for plant growth.


In early spring it is good to administer specific fertilizer every 10 days until flower buds develop. At the appearance of the first inflorescences the fertilizations must be interrupted.

Parasitic diseases

Epidendrum orchids can be attacked by scale insects, these must be removed with specific pesticides or natural remedies based on garlic, or Marseille soap.

The periods of pruning

The ideal time for prune orchids usually coincides with the post-flowering and exactly, with the withering of the flowers. Orchids have different flowering times, both because in nature there are many different species, and because of the manipulation of man.

It is also good to remember that light and sudden changes in heat can affect the flowering of these plants. Even experts argue that pruning can somehow delay or anticipate the flowering of orchids even if it has been ascertained that they are able to bloom all year round. In any case, it is important to remember that the pruning of orchids should only be done after the flowers have dried. For plants that repeat the flowering on the same stem, it is good to cut the same about 20 cm from the origin, after the node from where new buds will be born. For orchids that will instead perform the new flowering on a new stem, it is better to proceed with the total cutting.

Although this botanical species is easy to grow, it is advisable to follow some simple rules to offer it the optimal conditions for life.

Phalaenopsis exposure

This orchid must be placed in a bright position but avoiding direct contact with sunlight. Better to avoid exposing this plant to too high temperatures. During the summer, in the case of temperatures above 30 °, it is preferable to place it in a more shaded position. These orchids are easy to grow and have a remarkable decorative effectiveness thanks to their elegant bearing and the beauty of the colored flowers.

Phalaenopsis cure

This plant it requires constant humidity as long as water stagnation is avoided, which risks causing root rot.

Keeping the light conditions and temperatures to which the plant is exposed under control is the best way to ensure optimal care. For the rest it is a fairly easy botanical species to grow even at home.

Phalaenopsis rotten roots

Root rot is one of the most common problems faced by plants. Even the moth orchid is likely to suffer from it due to an excessive supply of water and consequent water stagnation.

Particular attention should be paid to watering as, in case of rotten roots, the plant could succumb.

Phalaenopsis flowering

Cared for under optimal conditions, this orchid can bloom up to 2-3 times a year. The blooms tend to be long lasting and produce brightly colored buds, ranging from white to purple through shades of pink.

The possible absence of flowers it is to be attributed to a poor light or to temperatures that are not adequate for the needs of this plant. Usually the flowering period coincides with the winter months, in particular it is possible to admire the inflorescences from December to April.

However, these orchids don't always follow a rule with respect to flowering. Ensuring the correct exposure conditions is an important step in keeping this plant in excellent health.

Phalaenopsis flowering duration

The flowering period of these orchids is very protracted over time. Even when cut, the flowers are able to last for a long time.

Phalaenopsis how long it lives

The moth orchid plant can live a long time and bloom again several times. Flowering lasts at least three months.
