PHALAENOPSIS culture sheet


October to April: Place the plant within 50cm of a well-exposed window with 2 to 4 hours of direct sunlight each day.

May to September: Same location but avoid direct sun from 10 a.m. to 4 p.m. which could burn the leaves. A light curtain may be sufficient to provide the necessary shade.


Temperate non-calcareous water see watering file HERE

Watering is done according to the color of the roots (or the weight of the pot)

Plant that requires watering

Temperature :

The majority of Phalaenopsis are greenhouse orchids: Ideal temperatures are 25-30 ° C during the day and 18-25 ° C at night. Hybrids can eventually adapt to cooler temperatures for a short time (without dropping below 16 ° C) provided the substrate is kept dry. The plant then comes to rest (it stops growing) and it is then necessary to let the substrate dry thoroughly between waterings and not to fertilize it.

Fertilizer :

Phalaenopsis are relatively greedy in fertilizer compared to other orchids. However, their needs have nothing in common with those of a classic green plant: A too concentrated fertilizer solution can seriously damage the roots. It will be necessary for each watering by measuring your water, see watering file HERE.


Young plants called keikis can appear on old flower stalks if left untrimmed. They are carbon copies of the mother plant. When the keiki has developed 3 leaves and 3 roots of at least 3 cm, it can be detached from the mother plant and be repotted separately in a very small pot.

Cut the stem or not?

When your phalaenopsis has finished flowering, some people will recommend that you cut the stem at the 2nd or 3rd "eye" in order to have a new bloom.


My advice: I especially recommend that you do not cut if the stem is not dry. By cutting, you run the risk of missing blooms which can start at the level of the bracts (the famous "eye") or keiki but above all of introducing viruses through this unnecessary cut.


After purchasing a Phalaenopsis and the end of its flowering, it is advisable to repot it in a suitable substrate.

!!! "Special orchid" type substrates sold in garden centers are not suitable! Composed of potting soil, they are suitable for Vanilla and Cymbidium.

Prefer a mixture prepared by a professional 

Repotting method:

Soak your Phalaenopsis for 30 minutes in lukewarm water to soak the roots with water and to be able to handle them with ease.

Discard the old substrate and clean the roots always with warm water.

Clean the old pot or opt for a slightly larger pot of an additional 1 or 2 cm in diameter if the roots have grown too much.

Put a little substrate between the roots and "turn" your plant as if you were screwing it into its new pot, pushing it in gently to bring in all the roots.

Complete with substrate, your plant is ready!
