FAQ

When should I mist my indoor ferns?

Mist indoor fern plants in the early morning or late afternoon when water evaporation is the least. Ferns like humidity, so make sure to mist your ferns as often as possible. Keep a misting bottle near your plant so when you walk by you can give it a mist. Alternatively, place a pebble tray filled with water so that the evaporated water can increase the humidity around the plants.

Do indoor ferns require a lot of water?

Ferns require a lot of water (or moisture) constantly. Keep your ferns in a humid location like a bathroom or greenhouse. You can also keep a humidifier or mist them on a regular basis. Lastly, water your ferns whenever the soil feels dry.

why do fern leaves turn brown?

Low humidity and underwatering cause Fern plant leaves to turn brown. Ferns are tropical plants that require humidity. Indoor humidity is frequently too low, which saps moisture from the leaves, causing them to turn brown, crispy, dried out, and dying-looking. Underwatering causes the tips of ferns to turn brown.

Can Ferns Grow Outdoors?

Yes, Ferns can grow outside. Ferns can be planted outside all year in mild climates that do not experience frost. Ferns thrive when planted in the spring after frost danger has passed, but you can plant at any time during the summer with little risk of them withering.

Are ferns toxic to humans and Pets?

Yes, some Ferns are toxic to humans and pets. Some Fern species produce spores that, when eaten, can cause poisoning. Toxins in the spores can seriously harm the health of humans and pets. The harmful effect varies according to the type. Some symptoms range from vomiting to heart issues. However, some ferns, such as the Boston Fern, are typically non-toxic to pets and make excellent houseplants.

Conclusion
