Blue Star Fern Light Needs
Medium to bright indirect sunlight is ideal. They tend to be happy anywhere, except in indirect sun.
How Often to Water
Water when the top half of the soil is dry, check it once a week. They must not sit in waterlogged soil, they can get root rot relatively easily as they do not live in heavy soil in their natural habitat.
Blue Star Fern Fertilizer
Use a balanced fertilizer once a month in the summer to encourage growth.
A standard potting will be too heavy, you need to make sure you have some really good drainage in it, like perlite and orchid bark. At the very least, add 25% perlite to the mix to ensure that the roots do not get water logged. The plant is an epiphyte naturally which means it grows in bark up in trees, not in the soil on the ground, so normal soil is likely to be too heavy for it and cause root rot.
When To Repot A Blue Star Fern
Repot once a year in Spring to renew the nutrients in the potting mix and pot it up a bigger size if the roots are crowded.
50-60% humidity is ideal, spray them occasionally, or put a pebble tray of water underneath them.
They do best in the range 18-26ºC (64-79ºF), so they’ll be fine in most houses.
Blue Star Fern Propagation
To propagate a blue star fern, divide it at the roots. Follow these steps:
- Empty the plant from it’s pot
- Take as much of the soil as possible away from the roots, you can do this by dunking the roots in a bowl of water to loosen them.
- Separate the plants out at the base. It is important that you take some of the roots and rhizome with each plant. You may need to break the roots or rhizome at times, but try to minimize the damage as much as possible.
- Let the new plants callous over for a couple of hours
- Pot them plants back up separately and water them.
Where To Buy

So, what are the fuzzy roots all about then? If you can see the fuzzy roots at the top of the pot what you are actually seeing is the rhizome, which is like a bulb that the plant shoots leaves upwards from and roots downwards.
