  Ferns are ancient plants which have successfully adapted to a variety of growing conditions. By looking closely at how and where they thrive naturally, gardeners can learn how to supply their basic requirements in a variety of settings. Whether grown outdoors or indoors these plants can provide years of beauty if certain basic conditions are maintained.
  
  

Above Ground Considerations

• Provide moderate humidity for ferns to thrive.fern image by Lytse from Fotolia.com
  
  Most ferns do best in partial to full shade, such as that found in woodland settings beneath tall trees. Some symptoms of too much sun on ferns are sunscald on the tops of the leaves, bright green new growth or new growth that is stiff and upright. Ferns do well in the low lighting found indoors.
  
  Ferns also require a particular temperature and humidity level to thrive. The ideal humidity range is between 40 and 50 percent. In outdoor settings, humidity is almost impossible to control. Indoor humidity conditions can be modified with misting or the use of a humidifier. Ferns enjoy their fastest growth rate when the temperature is between 73 and 86 degrees Fahrenheit.
  
  

Soil Conditions

• Ferns do best in loose soil that is rich in organic matter. In nature, fallen leaves decay and form leaf mold compost. Peat is another organic substance which helps provide the easily drained soil which ferns love -- and is readily available for use with potted indoor ferns. Because ferns are delicate with shallow roots, it is important to plant them where they will be free from damaging foot traffic.
  
  

Water Needs

• The lushness of a heavily wooded rain forest is the ideal environment for ferns; fairly moist at all times but not saturated is the standard. In most residential settings, the tall trees that provide the great shade shadow necessary for fern growth may block much needed rainfall. Thus, an irrigation system is required to provide the steady moisture that ferns require.
  
  When you water potted ferns, never submerge the plant. Instead, give indoor ferns a frequent light watering. Misting with a spray bottle is a good way to simulate the humidity levels ferns enjoy.
  
  

• Most of the 12,000 species of ferns are low maintenance and do well in a stable environment where water and temperature levels stay in the mild zone. Observe them in a nearby park or wooded area to notice the essential conditions which encourage their growth. Adjustments necessary to grow them in your own environment can be made easily.
