Calatheas are some of the most beautiful houseplants you can place in your home. With their dramatic patterns, colorful leaves, and unique movement of the leaves, they infuse any area with a touch of tropical beauty. It does take the proper harmony of care, though, particularly regarding sunlight. Too much sunlight can scorch their fragile leaves, but too little will cause them to fade out their beautiful patterns.

This manual will explain the best lighting conditions for Calatheas, typical light-related issues, and practical tips on how to keep your plant happy.

About Calathea Plants

Calatheas belong to the family Marantaceae, commonly popularly known as prayer plants because as evening descends, their leaves fold upwards, giving the impression of hands carrying out a prayer. Calatheas originated from Central and South American humid forests' lower canopies. Their natural growth environment reflects an impact on their light requirements since these will do very well in filtered light as opposed to direct sunlight. Calatheas are our favorite patterned plants.

Calatheas are among the most wonderful plants because of their friendliness around pets; hence, they are an outstanding choice for homes with dogs and cats. They symbolize new beginnings so you can gift them for weddings, anniversaries, and housewarmings.

Some of the most common types are:

  • Calethea Makoyana (Calathea makoyana): This one is mainly known for its striking foliage.
  • Calathea Rattlesnake ( Calathea lancifolia): A long, curly leaf plant with dark green stripes above and purplish in color.
  • Calathea Orbifolia (Calathea orbifolia): Well known for its big round-shaped leaves that have a soft silver-green marking.

All varieties add a touch of sophistication to the interior spaces but require exact lighting conditions to grow. 

How Much Light Does a Calathea Need?

Calatheas prefer bright or medium indirect light because they are badly harmed by direct sunlight since it causes their sensitive leaves to lose color, curl, or be covered by a brown spot. For example, if you grow them outdoors, then locate them in an area that is shaded but would still have access to gentle morning sun for about 4 to 6 hours.

If unsure about the home light condition, you can place your hand between the plant and the source of light, and it casts a shadow, albeit a soft one; then it is suitable. If the shadow is hard, it means that the light is too powerful, whereas if it casts no shadows, the light may be too dim.

Best Placement for Calatheas

Simulate the natural rainforest environment by placing your calathea in front of a window facing either north or east. These spaces trap brief afternoon rays of sunshine and benefit your plants with some morning sunshine. When placing your plant before a south—or west-facing window, use sheer curtains to filter the harsh sunlight and protect the leaves. It is one of the best plants for the living room.

Here are some ideas:

  • Several feet away from a bright window
  • Next to a window with sheer curtains
  • In a well-lit, humid bathroom 
  • On a shaded patio or balcony 

Can Calathea Grow Low Light?

Calatheas can generally tolerate low light, but they perform the worst in such circumstances. A lack of light often causes naturally slow growth and less vibrant leaf patterns. To correct this, grow lights can provide sufficient brightness, which would be very beneficial if natural light is limited.

Signs of Low Light Problems

  • Fading or dull leaf patterns
  • Slower growth
  • Smaller leaves
  • Drooping foliage
  • Stagnation in leaves (prayer plants tend to move up and down due to light variations)

Solutions for Low Light

  • Place your plant nearer a bright, indirect light source.
  • Employ a full-spectrum grow light for additional brightness.
  • Don't put it in dark places with no exposure to natural or artificial light.
  • Clean the leaves so they can absorb maximum light.

Can Calathea Get Too Much Sun?

Too much direct sunlight will harm your plant. Calatheas prefer to grow under the protection of trees, so direct sunlight will burn their leaves and parch them. As soon as you spot the results of over-sun, transplant your plant into a less sun-filled area. 

Symptoms of Too Much Sun

  • Color loss in the leaves
  • Browning, crisp edges
  • Curled-in leaves
  • White, bleached foliage patches
  • Patches of sunburn

Repairs for Excess Sunlight Exposure

  • Move the plant to a location with filtered or indirect light.
  • Utilize sheer curtains to filter out intense sunlight.
  • Raise humidity by misting the leaves or running a humidifier.
  • Water frequently, but do not overwater, as dryness can exacerbate leaf damage.

Keeping the Right Light Conditions All Year Round

Seasonal changes may impact the level of light your Calathea is exposed to. Here's how to modify care during the year:

  • Spring and Summer: When the sun is at its zenith, place the plant farther from the windows or shield it behind curtains to filter direct sunlight.
  • Fall and Winter: Since natural light is dimming, you can place the plant near a window or use a grow light for extra assistance.
  • Artificial Light: In regions with long, dark winters, a grow light provides the necessary glow for maintaining healthy growth. Preferably, pick an LED to produce light that emulates daylight.

Last-minute Tips for Your Healthy Calathea

  • Every few weeks, rotate your plant for even growth.
  • Avoid draughts from heaters or air vents. Hot, dry air will scorch the leaves.
  • Place mist leaves on a pebble tray, or use a humidifier to maintain humidity.
  • Check the moisture of the soil regularly. Calatheas enjoy humidity but dislike wet soil. Allow the top inch to dry out before watering again. Do not overwater them.
  • Use distilled or rainwater if you have it, as tap water causes mineral buildup, leading to brown tips on the leaves.

Final Thought

Calatheas are beautiful plants that love the right amount of light. Keep them in bright indirect light, away from direct sun, and rotate them as necessary, and you will then be able to enjoy the magnificent foliage throughout the year. Watch the leaves for signs that tell you when to adjust their light conditions; with a little bit of care and attention, your Calathea will reward you with rich, beautiful growth for years to come.
