Light levels dictate everything else.
The more light a plant consumes, the more water it needs. For example, this Pink Princess Philodendron and Lilies are getting tons of light.
That means they need lots of water.
The number one issue we see in plant care is overwatering.
Light sets a plant's growth. It determines everything else. It sets how fast of a car we're driving. Is it a Ferrari, or is it a Ford Pinto?
The more light we have, the more water we can consume, the more CO2 we can turn to oxygen.
Water consumption is driven by the amount of light.
Because light and water go hand-in-hand in consumption during photosynthesis, the more light a plant is exposed to the more water it will need.
Now, don't run off after seeing this next diagram (this isn't a 7th grade science lesson).
The photosynthesis diagram simply shows light being absorbed, which kicks off a process that helps the plant grow.
But it all begins with LIGHT!
Understanding this should allow you to care better for your plant. Are you wondering how much to water? Consider how much light your space has to provide.
If it's dark, don't water much. If it's bright, water more! Here's a video on that.

Thank you!!! My fiddle leaf fig seems to be suffering from root rot and I think it’s because I was overwatering – even though I was only watering when the top of the soil was dry, the room I have it in does not have enough indirect bright light so I think that made it easy to overwater & unfortunately susceptible to root rot. Not enough people talk about this relationship between light and watering! I let the soil dry completely and just watered with a hydrogen peroxide / water mix. Hopefully this and moving it to a brighter spot will help resolve the root rot.
That was helpful. Thank you.
