Temperature

• Ficus trees need moist but not wet soil. If the temperature indoors is dry and hot, the tree may need water every other day or every few days as the soil will dry out more quickly. If the first inch of soil is dry, the tree needs water.
  
  

Light

• Trees that sit in direct sunlight, which is preferred, will need water every few days as the soil dries out. If the tree is in an area with low light, it will require watering less frequently.
  
  

Watering Correctly

• Watering the ficus thoroughly can help you determine when to water next. Add water to the ficus until the water runs out the bottom.
