Basic Boston Fern Care

We have a bit of a love-hate relationship with Boston Ferns because whilst their incredible leaves and tropical feel is worth all of the effort, their care routine can be a bit tricky to get right. They need just the right light level (not low light but not direct light) and will crisp up instantly if you aren’t watering enough or boosting the humidity. So the spray bottle will be your best friend when caring for a Boston Fern.

In this care guide, you’ll find all the information you need to help keep your Boston Fern looking and feeling healthy!

Detailed Boston Fern Care

Boston Ferns like bright, indirect light

Boston Ferns can deal with very bright spots but be careful not to expose your fern to too much direct sunlight as their leaves are quite delicate.

Boston Ferns thrive in damp soil

Dry soil is one of the main reasons why Boston ferns do not survive. It is very important to give your boston fern a little more humidity in the cold months as if you have the heating on, they can get very dry very quickly. To increase the humidity try misting your fern every few days.

Boston Ferns prefer cooler temperatures

Boston ferns prefer a slightly cooler environment and will struggle with temperatures above 24C. Try to keep fresh air flowing through the room to prevent heat from building up. 

Hold off the fertiliser

Boston ferns don’t really need to be fertilised often. A few times a year or so will do as overfertilisation can harm your plant. 

Propagate your Boston Fern using division

Boston Ferns are very easy to propagate as you can divide the plant into several smaller plants which will each flourish and continue to grow.

Make sure to mist your Boston Fern

Boston Ferns love humidity so it’s important that you mist their leaves every so often. This also removes any dust from the plant.

Boston Ferns love moisture

You can increase the humidity around your boston fern  by 70% by placing it on top of a tray of pebbles and water. Make sure to keep the water level below the plant so your fern isn’t sitting in stagnant water.

Boston Ferns are safe for pets

One of the great things about Boston Ferns is that they are non-toxic to pets. So you don’t need to worry about having these in your home if you have dogs or cats.
