When to Water
Low Frequency - Water When most of the soil is dry [80% of the soil] 

Check the soil moisture level every 10 to 12 days.
Remove some of the pine bark on the soil and stick your finger or stick 5-7cm deep into the topsoil to see if it is dry. [if there are no soil stick in your finger or stick, it means the soil is dry]
Depending on the actual environment and plant conditions, adjustments may be needed.

The watering schedule may be less frequent during the winter month

Watering Volume
When you water, you can use 800ml as a testing point for floor plants and 250ml for table plants, evenly pour over the soil (not necessarily to remove the pine bark).

Check the saucer and see if there is any water in it. If yes, that means enough watering.

#Don’t forget to remove the excessive water in the saucer, a absorbent towel may also help, to avoid mosquitoes breeding.
#Overwatering may be caused to brown leaves, brown leaves spots, and soft leaves
