Calathea White Fusion Growing Conditions

Since this plant is native to tropical regions of America it prefers an environment that resembles its native lands.  It should be set in an area that has temperatures that range between 60 and 77 degrees Fahrenheit.  It will also need humidity levels that are at least 75%.

It is also recommended that it be kept away from cold drafts and air conditioner and heater vents. During winter, it can get shocked from being in a heated room all day and then left in a room that is cold at night. Temperature range should be taken into consideration when deciding where to plant a Calathea White Fusion.

A plant humidifier or pebble tray and a heat mat can be utilized to provide the heat and humidity this plant needs without creating an indoor environment that is uncomfortable for humans and pets.

  • Slowed growth
  • It requires more than two watering sessions a week
  • Its roots are growing out of its container’s drainage holes
  • Its foliage looks too heavy for its current container

To reduce the chance of shock, the repotting process should only be done in the spring or summer.  This process will benefit the plant by providing it with fresh soil and more room for its root system to grow.  The steps for repotting a Calathea White Fusion plant are:

  1. Choose a plant container that is 2 inches larger in diameter than its current container
  2. Fill the plant container potting soil
  3. Create a hole in the soil for the plant to set inside
  4. Carefully remove the plant from its current container
  5. Gently dust off any excess soil from its roots
  6. Using a sterile cutting utensil, cut off any rotten roots
  7. Set the plant into the hole in the new container
  8. Spread the soil around so that the plant is secure in its new container
  9. Water the plant
  10. Set it in a warm spot with plenty of sunlight

Calathea White Fusion Potting & Soil

This plant requires soil that drains water well but can still retain some moisture.  This is so it doesn’t sit in either dry or soggy soil. It is particular about its soil condition since too much water can cause root rot. This is why it is so important that it be planted in a container that has drainage holes.

These are both great options to use for any Calathea plant:

Along with a well-draining soil mix, Calathea White Fusion requires soil that has a pH level ranging from neutral to acidic.  Use a Soil pH Meter to test soil pH levels to know which direction they should be adjusted.  To create higher levels of soil acidity for a Calathea Rattlesnake, add bone meal, hardwood ashes, or ground eggshells to it.  For a more detailed look at how to adjust soil pH levels, read this article.

Calathea White Fusion Water Requirements

This type of plant needs moist soil all the time.  The best way to confirm that a Calathea White Fusion needs a drink is to test its soil moisture.  If the top inch of its soil is dried out, it needs a drink; however, if the top inch of soil is soggy, it does not need a drink.

It is best to water this plant with either rainwater or distilled water that is lukewarm. It can be watered with tap water as long as the water has been set out for at least 24 hours so that the minerals in it have time to evaporate. Use a plant watering app to help track when a plant has been watered, set reminders to water it, and get answers to common plant care questions.

Calathea White Fusion Light Requirements

This plant should be set in an area that receives plenty of bright but filtered or indirect sunlight.  It should never be set in direct sunlight because this will cause the variegations on its leaves to fade or disappear.  However, if it is not given enough sunlight, its variegation will not develop. Use a light meter to ensure that this indoor plant is receiving adequate amounts of sunlight.
