How to make white orchids grow strong and vigorous?

One of the most important keys to growing white orchids is related to the climate. This determines if they can survive indoors or outdoors, in gardens and terraces.


If you live in a place where temperatures remain stable, above 10ºC, it is very likely that they will remain outdoors.

The main thing is to place the plant in a place that has very good natural lighting, as long as direct sunlight does not reach it, because that is fatal for its development.

If the area where you live is cold, with frosts and significant drops in temperature, then the most viable option to take care of the plant is a very bright place inside the house, clear, where sunlight reaches indirectly.

potted life

What humidity do white orchids need?

In closed environments of the house, it is very important that the plant is not placed in places where drafts circulate.

Regarding irrigation, a clear recommendation must be followed to the letter: water must be added only when the substrate dries, preferably rainwater, without lime or osmosis.
