Use fresh water and pour it directly around the base of the plant. No need for deep watering and bottom watering.

Hot weather increases the transpiration rate. Therefore, in a hot environment, you need to give more water to your plants.

Whereas in the winter season watering once in 2 weeks is enough to keep it healthy and alive.

I use filtered water for watering my all-indoor plants. They all are happily growing and never face overwatering and underwatering issues.

Filtered water is easy to absorb and plants can store it in large quantities in their leaves and stems.
