Calathea rattlesnake plants thrive when placed in environments with filtered light. You can do this by putting your Calathea rattlesnake plants near windows with drapes. Placing them in a well-lit room away from direct sunlight is also an excellent solution.
It’s essential to give your Calathea rattlesnake plants the right amount of sunlight. Exposing them to direct sunlight for extended periods can cause their colors to fade and their leaves to wilt.
Calathea rattlesnake plants grow over the summer period, so water them frequently during this time. To prevent waterlog and root rot, let their soil or potting mix dry between waterings. You can determine the moisture levels of the soil by sticking your finger into it.
