Orchids have a reputation for being difficult to care for, especially when it comes to their flowers. However, on this occasion we have chosen to talk about orchids dendrobium, a species whose care is very simplemaking it ideal for those who do not consider themselves experts in gardening.

The idea is to demystify the complexity of orchids and show that they are worth growing. When they bloom, they draw all eyes. Only within this species there are more than 1500 varieties that have adapted to the geographical conditions that saw them develop.

We will review its most important characteristics, some of the most common varieties of orchids and the care we must take when growing them.

Types of Dendrobium Orchids

This type of orchids belongs to the family of epiphytic plants. This means that they need another plant to grow, such as trees.

In fact, his name makes it very clear. dendro comes from the Greek and is “tree”, while bium It refers to life. In any case, they also grow in the ground and in pots without problems.

They come from Asia and part of Oceania, although they have spread and adapted to climatic and geographical conditions around the world. Although they prefer warm climates, they can now be grown successfully in non-tropical areas.

With so much variety, it is not surprising to find a wide diversity, not only in terms of the colors of the flowers, but also the type of flower and parts of the plant in which they develop. It also changes the time of year they bloom and how long the flower lasts.

The orchids dendrobium They are classified into 6 groups. The dendrobium phalaenopsis is the most common. You can find it at any nursery or garden store.

Specimens of this species are evergreen and develop better in warm areas. They bloom in autumn, while in winter the plant seems to go into dormancy until spring, when it blooms again.

Orchids grow in pots. Although their natural habitat is in trees, they can be cultivated in other ways.

General care of Dendrobium orchids

We have already reviewed its most outstanding characteristics, so now we will focus on the care that this variety of orchid requires. The first distinction we will make will be between the soft cane and the hard cane.

The first tend to be without leaves in winter and sprout again completely with the arrival of spring. It is not a minor detail, since it is common for you to think that the plant has dried up and stop taking care of it.

He did not die, only entered a period of stagnation until the days of low temperatures are over. As for its leaves, they are light green and the plant in general is very leafy.

With regard to hard cane orchids, we can say that the main difference is that these do not lose their leaves in winter, are spiky bulbous and reach a good height. Also, the leaves are dark green.


The hard cane ones have green leaves all year round, so require regular watering at any time. It is important to clarify that regular irrigation does not imply that it is daily. In fact, the orchids dendrobium They are not watered every day.

Generally speaking, 2 times a week would be a suitable frequency. This is because the substrate does not have to be always wet. The ideal is to water it in the morning with abundant fresh water free of salts.

Soft cane orchids need little water during the fall. Nevertheless, you must be careful so that the pseudobulb does not wither that the plant has

The importance of not overdoing the water is that if the root rots, the flowers and leaves will fall. Then, spots will appear on the stems. This discomfort in the plant is not easy to reverse.


As for the light that orchids should receive, those of hard cane do not need much, while those of soft cane demand more. Ideally, place them near a window, but through which the sun’s rays do not enter directly.


Both types of orchids share the substrates. Keep in mind that the pot is not too big, as well as not compact the substrate too much.

One of the most common and simple alternatives is to add a special substrate for orchids, which you can buy at any nursery. It usually contains bark, gravel and porous material.

Those of hard cane need a permanent payment with fertilizer in the months of growth. Also in winter.


At this point there is also a coincidence between the orchids of hard cane and those of soft cane. Both need good environmental humidity. In dry seasons, you can spray its leaves with a special liquid for orchids.

The atomizer method to maintain the humidity of the plants is ideal. Simulates a concentration of water in the environment that replicates tropical atmospheres.


In relation to the ideal room temperature for orchids dendrobium, there are differences in requirements between hard cane and soft cane. The first ones need a temperature that oscillates between 30 °C and 16 °C. On the contrary, those of soft cane need a thermal amplitude, especially when flowering approaches: 30 °C during the day and about 10 °C at night.

cultivation of orchids

New plants can be made from an orchid that you already have at home. Just keep in mind that must be at least 4 years old and be in excellent condition.

With a knife and carefully, cut the rhizome and the roots that are in it, trying not to damage the root mass. Clean them and cut off any dry or brown roots.

Then, place them in a container slightly larger than the set of roots and add a special orchid substrate. After a couple of days, water the new plant.
