How much water is required for coconut trees?

Hi Sharon, here's some information: https://gardenerdy.com/coconut-palm-care

Where do you live?( this is world wide site) - minimum 50-120 litres a day just depends as I asked where you live rain fall you get(they need 40-60 "s annually),on shoreline somewhere -you have higher humidity can you install drip lines would be best for contiunal slow watering 3-4 per tree recommended. Great info. on this site just past watering charts http://www.agritech.tnau.ac.in/expert_system/coconut/coconut/coconut_irrigation_management.html

Water them normally daily, but don't overwater it. It should not sit in water.

Best way is to touch the soil with your fingers, if you feEl soil is dry then water it, otherwise if you feel soil is wet or moist then do not water it.
