Ostrich Ferns just like many other type of ferns prefer to live their life in the shade. They don’t like bright direct sunlight as the rays can scorch their fronds. Instead they like to grow under the shelter of other plants and in the shade.
As these plants don’t tend to grow too big, are easy to trim and normally grow under the canopy of other plants anyway it shouldn’t be too difficult to keep them out of the sun. If you’re planting an Ostrich Fern in your garden then try to plant it where it will receive shade from a wall or fence or where it will be able to grow up underneath other plants in the area.
Another consideration is you’re planting one in your garden is to think how big do ostrich ferns get? Will you have the space for them? Remember that a garden will look beautiful if you give it lots of different levels and ferns can be a great way to achieve this.
If you’re looking to keep your Ostrich Fern inside then simply pull it back away from the windowsill so that it doesn’t receive too much light or consider placing it on a north facing windowsill rather than a south one. In the winter you can allow your fern access to more natural light as the rays will be a lot weaker during these months.
So to summarise: how much sun can Ostrich Ferns take? In cooler climates they can tolerate some sun but definitely prefer bright indirect light or a shady placement. At the end of the day you can choose where ever to put your plant but if you do place it in direct sunlight then you may find the fronds becoming damaged and the plant not doing as well as you want it to or even dying under extreme circumstances.
