Ferns produce vivid green foliage.
Ferns range in size from a few inches tall to 6 feet tall.(See reference 1)They produce foliage in light to dark green colors. Some ferns are grown indoors, though due to low humidity levels, it's often easier to grow them outdoors.
Proper planting and care of ferns helps them thrive when planted inside or outside. Knowing the most ideal growing conditions is the best way to get your ferns off to a good start.
Moisture
Ferns require constant moisture in order to thrive. Confirm the fern receives at least 1 inch of water each week, either through nature or by hand. Some ferns are watered by placing the ferns in a pan of water and letting them soak for a while. While ferns do require a significant amount of water, letting them soak in water for too long may contribute to root rot. Root rot is caused by letting the roots of a plant sit in standing water for a long period of time. The roots become weak, thus impairing the ability to transport nutrients to the fern.
Shade
Ferns thrive when planted outside in partial shade. They tolerate indirect sunlight well. Some varieties tolerate full sun, though the majority prefer at least some shade during the day. If growing ferns indoors, provide a space near a window where it receives indirect sunlight. Rotate the fern so all sides receive the same amount of indirect light.
Nutrients
Ferns need regular fertilization to provide nutrients to the soil. Be careful not to over-fertilize the fern, as this contributes to scorched foliage. To prevent over-fertilizing ferns, always follow the recommended application rate on the fertilizer label. While many types of fertilizers exist, choose one that has equal parts of ammonia and nitrogen for best results.
Soil
Ferns prefer well-drained soil. Well-drained soil means the water runs through the soil at an even rate, without causing root rot. To improve the drainage ability of the fern's soil, consider adding peat moss or other organic materials to the soil, available at garden centers.
If you're planting the fern in a pot that had previously contained another plant, clean the pot well with soap and water. This helps prevent the chance of a plant disease spreading to the fern, if the previous plant was affected.
Humidity
Ferns grown indoors require a humidity level of at least 30 percent. Ideally, the humidity level should be 40 to 50 percent. Increase humidity by misting the fern with water once a day and by adding a humidifier in the room where the fern is growing.
