They are plants that adapt perfectly to bright places without direct sun, for this reason, different varieties of orchids per apartment are perfect for decorating your home.
Although we have already talked about how to take care of orchids in another article, today we want to focus instead on the most common varieties of orchids and on the suggestions to make them last longer.
Caring for Phalaenopsis orchids
The flowering of Phalaenopsis is very long, therefore ideal for home decoration.
Phalaenopsis is one of the best known and appreciated varieties of apartment orchids. Perhaps for the long duration of its blooms (between 2 and 5 months) or the ease of cultivation.
It prefers a bright position without receiving the sun directly on the leaves. They are not very demanding in terms of light, so if you have other plants and limited space, you can decide to give priority to other plants.
Like other types of orchids, it loves the heat, always avoiding drafts.
Most Phalaenopsis are sold in transparent pots so that we can check the color of their roots: they will tell us when we need to water them.
They will have an intense and bright green color after watering, instead, they will take on a greyish green tone when they are dry.
A brown, cream or translucent color is a sign of putrefaction or excessive watering.
Phalaenopsis should be fertilized approximately every 15 days. In spring, with a nitrogen-rich fertilizer that will help it grow, and in autumn with a potassium-rich fertilizer that will induce flowering. During the rest of the year, use a balanced fertilizer (with the same amount of NPK nutrients).
When the flowers of your Phalaenopsis fall, do not cut the faded branch. Let a few weeks go by, see what happens. It may soon form new flowers, or new seedlings (called Keiki ). If it dries, cut it under the first knot starting from the base.
Caring for Cymbidium orchids
The floral branches of the Cymbidium orchids, when ready, grow from the hanging stems.
Contrary to what happens with Phalaenopsis, Cymbidium develops from rhizomes. Every year new stems appear falling in the base which will form new leaves and a floral branch.
Like the rest of the orchids, it prefers very bright places with no direct sun (except in the winter months).
In hot areas and without the risk of freezing, they can also be grown outdoors.
Abundant in summer, avoiding stagnant water. The ideal would be to prevent the substrate from drying out completely before watering again.
Fertilize every 15 days with the best fertilizer based on the time of year: in autumn it will appreciate a fertilizer rich in phosphorus and potassium to favor flowering. The rest of the year it will be sufficient to use a balanced orchid fertilizer and one rich in nitrogen during the spring to favor its growth.
It is possible to induce the plant to bloom in autumn by changing its position overnight. If the plant notices a change in temperature between night and day (it is sufficient to move it in a corridor or on the balcony), in most varieties of orchids as a reaction it will give rise to a new flowering.
You can divide the plant in the spring, separating the bulbs and removing the damaged roots. Use a special soil for orchids and do not transplant them into too large pots: orchids bloom sooner if they are “narrow”.
Caring for Dendrobium orchids
The shape of the flowers of some types of Dendrobium orchid can be confused with that of Phalaenopsis.
The Dendrobium variety forms its flowers on sticks or directly on the “canes”. If yours is white and has so many flowers that you can barely see the stems, it’s probably a noble Dendrobium.
It needs great brightness avoiding direct sun. The color of the leaves will indicate if the position is to your liking: dark green means lack of light, yellowish-green on the contrary too much.
In winter, you should prevent the temperature from falling below 10ºC, or the plant will be affected. It is advisable to avoid a position with drafts.
Dendrobium requires different irrigation depending on the season of the year. In spring and summer, it is to be watered when we notice that the soil is drying. During autumn and winter, we distance the irrigation, checking the appearance of the reeds and the hanging stems. They must remain smooth and wrinkle-free, biweekly irrigation will probably be more than enough.
After flowering, we will see that new shoots begin to form. Fertilize every 15 days to grow them and instead suspend when it is time to decrease the watering.
Do not change your Dendrobium orchid when its flowers are about to bloom. They don’t like changes and may lose all the flowers.
It is possible to cause it to bloom in a similar way to Cymbidium orchids. When we see the buds begin to form, we place the plant in a bright position, watering it more often. It is not convenient to change places when the flowers are about to open, because they may fall.
- The new plant (“keikis”) is formed along the reeds or at the base of the plant. Let it grow and form roots before separating it from the mother and transplanting it into a new pot. It detaches easily, with a simple rotation.
