About Erect Sword Fern
The erect sword fern is native to the Hawaiian Islands where it is known as kupukupu, okupukupu or ni'ani'au. It has been introduced to several habitats where it has become an invasive species, such as New Zealand and Florida. To protect your local ecosystems (especially if you live in a warm, tropical climate) we suggest growing this plant only indoors. 🪴

How to fertilize Erect Sword Fern
Most potting soils come with ample nutrients which plants use to produce new growth.
By the time your plant has depleted the nutrients in its soil it’s likely grown enough to need a larger pot anyway.
To replenish this plant's nutrients, repot your Erect Sword Fern after it doubles in size or once a year—whichever comes first.

Lemon Button Fern #ErectSwordFern I just got lemon and was wondering how do I take care of him. I'm pretty new to ferns and will take any advice on how to keep him alive.

How to help lemon button fern/erect sword fern thrive? Hey yall! I’m super new to plants, and I got this lemon button fern back in May. It’s my first ever houseplant that I’ve managed to keep alive for so long, and I’d like to keep it that way as best I can, lol. He’s been growing, but slowly. The best way I could describe it is surviving but not thriving. I have a humidifier nearby and I keep him in a north facing window. I notice the fronds lose leaves the closer they get to the soil. If any of yall have any tips to get him in better shape, I’d really appreciate it! ^_^ #NewPlantMom #PlantTherapy #HappyPlants #PlantsMakePeopleHappy #PlantAddict

Just got this little one. I have a spot that receives lots of filtered light but is a little darker, but near my bathroom so lots of daily humidity. Should I put it there even if the light is less? #ErectSwordFern

Is my fern big enough to propagate yet? Hi all! I have a closed terrarium and an erect sword fern inside. He’s getting a little big and I’m wondering if he’s big enough to prop by separation yet? #ErectSwordFern #Terrarium #HappyPlants #PlantsMakePeopleHappy #PlantAddict #NewGrowth #Propagation

i find it hard to keep alive, but watering it a little more often than the app suggests seems to do the trick

Picky with humidity and doesn’t like tap water. Does grow quickly and with gorgeous bright green growth. I keep mine at ~85% humidity with grow lights and spagnum moss covering the soil for extra moisture

Drinks water like a fish! Self-watering planters are a must. Lots of new growth after transplanting to SWF
