Hi @caitlinlovessnails
Thanks for your enquiry, and yes, you've come to the right place! The Garden Ninja forum is here to answer any plant, garden design or gardening query!
What's interesting is the plant you're asking about is not a house plant at all,but a large hardy perennial shrub!

Fatsia japonica other wise known as the castor oil plant will grow to about 2 meters tall. It survives pretty much most British climates even some frost. It has these huge tropical-looking leaves that gives the impression its tender but Fatsia is a bullet proof plant.

The reason your Fatsia is crisping up, turning brown and looking lacklustre is that it will have undoubtedly used up all the nutrients in that tiny pot. Fatsias need space and room to grow. Whilst not the fastest growing shrub they won't survive in small congtainers for long without looking sorry for themselves.
Once in the ground Fatsia will even flower with these alien looking beautiful flowers in Autumn when everything else is starting to fade which then turn into these strange dark purple berries.

My advice would be to get it outside somewhere at the back of a flower bed. If you've not got a garden or space then a really large pot going to be required inside. I'd personally give it to a friend with a garden and instead, pick a similar house plant like Monstera that's better suited indoors.
Happy gardening!
