Blue Orchids Light Needs

Medium to bright indirect light. No direct sun though.

How Often to Water

Orchids are epiphytes, they grow on trees in the wild, not in soil. So you have to be careful and not let them sit in heavy wet soil. Check them every week in the winter and twice a week in the warmer months. Water them only when the top 50% of the medium is dry.


Use a well diluted balanced feed once a week to encourage growth.

Blue Orchids Soil

The best thing to do is give them a specialist dedicated orchid bark mix. This will mimic their natural habitat as best you can. Do not use normal potting compost for an orchid as it will very likely lead to root rot.

When To Repot

Repot it once it has died back after blooming. They will be fine in the same size pot a lot of the time, but it is a good idea to give it a fresh new potting medium.


Aim for 50-70% humidity for a blue orchid. You can up the humidity with a wet pebble tray.


15-30°C (59-86°F) is a good range to aim for.

How To Propagate Blue Orchids

You can propagate them using stem cuttings, you want a part of the stem with 2 nodes. Then put it in a take out tub of moist sphagnum moss, so hat the nodes are touching the moss. Put a few holes in the lid and then put the lid on, so that humidity will be high, but air can also move to avoid rot. Keep it in bright indirect sunlight. When it roots you can move it to an orchid bark mix.
