Why are all the leaves falling off my Boston fern?

It could be it's way too dry. Ferns need a lot of humidity. Try putting it in your bathroom and turning a hot shower on and letting it steam once or twice a week.(Dont let the water hit the fern, just set it in the bathroom near the shower or in the back of the tub) If at all possible buy a humidifier for it..this will add more moisture to your air. During the winter, the air gets very dry indoors...too dry for certain plants. Misting the leaves lightly a few times a week is also good for them.


Good luck!

Why are all the leaves falling off my Boston fern?
Could be many reasons. Exposed to too much sun? Are the leaves burned too? Has it been exposed to cold temperatures? The leaves can be burned from the cold too. How often do you water it? Maybe it's too dry. If none of these suggestions could be the problem..maybe it has scale. Look on the under side of the fronds and see if there is a scaly looking substance. If so you will need a pesticide. If this still isn't the solution, then you may want to cut back your fern. If you look in the bottom of your fern, where the plant actually comes out of the soil you will see little sprouts/new growth. It will look like little curled up kinda hairy little green growths. You can actually cut your fern all the way back leaving only the new growth and it will all grow back in time. Be sure you are fertilizing it as well, probably twice a week if you cut back. Good growing.
Reply:That sounds like the fern has gone through some shock, and it is now shedding it's leaves. Maybe it was exposed to some cold weather for a little too long.
