Also asked, can a Boston fern live outside?

Although Boston fern is often grown as a houseplant, it thrives outdoors in warm, humid climates in USDA zones 9-11. With adequate moisture, the plant may tolerate drier climates. Frost may kill the fern to the ground, but it will rebound in spring.

Additionally, are ferns indoor or outdoor plants? Ferns thrive in moist, shady outdoor areas, but the lush green foliage can also grow well in a hanging pot either indoors or outdoors. The smaller amount of soil and limited space means a fern growing in a container dries out faster than those planted directly in the ground.

Additionally, how much sun does a Boston fern need?

Boston fern light needs vary depending on the time of year. The plant benefits from bright, indirect light during fall and winter. A location where the plant gets at least two hours of indirect sunlight per day, preferably in the morning or late afternoon, is ideal.

How do you take care of a Boston fern indoors?

To care for Boston ferns, keep them outdoors if you live in a warm, humid climate, or keep them indoors if you live in a cooler climate. If you keep your ferns indoors, place a humidifier near them so they don't dry out. Water your ferns regularly so that their soil is always moist but not damp.

Do ferns need a lot of water?

Outdoor Ferns
As a rule, they prefer 1 to 2 inches of water a week, but this also depends on the soil and the growth rate. Ferns grown in light, sandy soil require more frequent watering than those grown in dense clay soil. Check the soil often and develop a watering routine that keeps the soil moist, but not soggy.

How often do you water ferns in hanging baskets?

Water only when soil is just dry to the touch. If leaves turn yellow and soil is wet 1 to 2 inches beneath the surface, you are watering too much. Ferns love humidity and appreciate an occasional misting.

Why are my outdoor ferns turning yellow?

Wet Soil. Overwatering ferns is a common problem that causes their leaves to turn yellow. After mixing the fertilizer with water, apply it directly to the soil. Yellowed fronds may dry and die, but new fronds will grow if the plants are watered properly with fertilizer applications.

Can you propagate ferns in water?

Cover a tray with pebbles and place under the pot with the fern. Pour some water on top of the pebbles. As the water evaporates, the humidity will help the fern grow. As the fern gets larger, use a spray bottle with a mist setting to gently moisten the leaves with room temperature water.

Why are my outdoor ferns dying?

The two most likely causes of the ferns turning brown are normal browning or not enough water. Your ferns are under a tree and may not have gotten enough water during the hot dry week. They do best in moist soil. Normal browning of fern fronds usually occurs on the oldest fronds that are closest to the base.
