Buy small ferns (ideally that come in a tall container) or buy a larger fern and repot it in a larger container.
Place the fern outdoors once the outside temperatures begin to warm at night (above 45 degrees Fahrenheit) or bring the ferns inside if temperatures fall below 45 degrees.
Place the ferns in a location that is shady, receives indirect sunlight, or dappled light like on a porch or covered deck.
Make sure the fern receives plenty of water. Daily water is ideal but a minimum of once every 3 days (a deep soak) is a must.
Mist the ferns on dry/hot days to maintain a humid environment.
Fertilize but do not over fertilize.
Take the hanging fern baskets down on windy days to keep them from drying out or becoming damaged.
Remove spent and browned branches at the base of the fern as they appear.
Rotate the ferns weekly so that they grow symmetrically.
Once the fern becomes root bound it is time to divide the plant or repot into a larger hanging basket.
Deter birds and other critters from nesting in the ferns.
After the season is over, plant the in the ground if the fern is native to your area or bring the fern inside and place in a cool location that receives indirect light for the winter.
