Ficus benjamina, also known as weeping fig, is one of the most popular house plants. It thrives on a minimum of care and is virtually impervious to insect infestation and disease. During the life of your potted ficus, its main requirements are warmth, sun and sufficient and regular watering. But rather than blindly following a weekly watering schedule, you should get to know your ficus' specific water needs. Every ficus is different, and it's water demands depend largely on the location in which it is grown, the size of its container and the size of the ficus itself.
Insert a finger into your ficus' soil to check its condition. It only needs water when the top inch or so of its soil is dry.
Use a watering can to water the ficus with room-temperature water until you see water coming out of the drainage holes in the bottom of the pot. Avoid wetting the ficus's trunk and foliage.
Remove the water from the drainage tray beneath your ficus plant after 30 minutes. If left there, the excess water will be reabsorbed and will make the ficus's roots too moist.
Mist the ficus's foliage with distilled water once or twice weekly during spring and summer.
