Care Essentials
Get to Know Your Calathea Corona
The #1 killer? Overwatering. Let the soil dry between waterings and your Calathea Corona will thrive.
Light
medium to bright indirect
Most comfortable in medium to bright indirect light. Avoid prolonged direct sun exposure.
💡 Grow lights: Thrives under artificial grow lights (LED or fluorescent, 10-12 hours/day). A great option if your space lacks natural light.
Watering
every 10-14 days
Let the soil dry out significantly between waterings — this plant is very sensitive to overwatering. When in doubt, wait another day.
Humidity & Temperature
Appreciates some humidity but adapts to average home conditions. Brown tips in winter? Your air might be too dry — a light misting helps.
Standard room temperature (60-80°F / 15-27°C) is perfect. Avoid cold drafts and sudden temperature swings.
Soil
Standard well-draining potting mix works well. Add perlite for extra drainage if you tend to overwater.

Why is my Calathea Corona wilting?
Drooping or rotting stems on a calathea corona are attributed in the source to one of two named causes: overwatering (saturated soil that never fully drains) or cold temperatures, since calatheas are sensitive to chilly environments and any sudden change in indoor temperature

Why is my Calathea Corona wilting?
Drooping or rotting stems on a calathea corona are attributed in the source to one of two named causes: overwatering (saturated soil that never fully drains) or cold temperatures, since calatheas are sensitive to chilly environments and any sudden change in indoor temperature
Cause
Drooping or rotting stems on a calathea corona are attributed in the source to one of two named causes: overwatering (saturated soil that never fully drains) or cold temperatures, since calatheas are sensitive to chilly environments and any sudden change in indoor temperature.
Solutions
- Adjust watering so the soil is moist but never soaking wet, allowing the top 2" (5cm) to dry before the next drink and ensuring excess water drains out of the pot drainage holes so the plant is never sitting in water.
- Move the calathea corona into the recommended 65–77°F (18–25°C) range, away from drafts, chilly windows, and indoor heating sources that cause sudden temperature swings.
Prevention
Site the calathea corona in bright indirect light in a stable warm spot between 65 and 77°F (18–25°C), keep humidity high with misting or a pebble tray, and water only when the top of the soil has dried so the stems stay firm and upright.
Why are my Calathea Corona leaves turning yellow?
Yellowing leaves on a calathea corona can come from two clearly named causes in the source material: overwatering (saturated roots leading to yellowing leaves), or an accidental treatment with neem oil, which the book warns does not agree with calatheas and will cause the leaves to turn yellow and fall off

Why are my Calathea Corona leaves turning yellow?
Yellowing leaves on a calathea corona can come from two clearly named causes in the source material: overwatering (saturated roots leading to yellowing leaves), or an accidental treatment with neem oil, which the book warns does not agree with calatheas and will cause the leaves to turn yellow and fall off
Cause
Yellowing leaves on a calathea corona can come from two clearly named causes in the source material: overwatering (saturated roots leading to yellowing leaves), or an accidental treatment with neem oil, which the book warns does not agree with calatheas and will cause the leaves to turn yellow and fall off.
Solutions
- Stop watering on a schedule and only water the calathea corona once a week, checking that the top 2" (5cm) of soil is dry first, and always let excess water drain out of the pot drainage holes so the plant is never sitting in water.
- Switch pest treatments away from neem oil; if leaves have yellowed after a neem spray, rinse the foliage with a gentle stream of water and treat future infestations with the castile soap and water mixture recommended for the genus.
Prevention
Use only distilled water or rainwater on a calathea corona, keep it in bright indirect light away from drafts, and never let the pot sit in standing water so the roots stay aerated and the foliage keeps its patterned color.
Pests (1 topics · 1 cases)
Why does my Calathea Corona have spider mites?
Spider mites are listed as the most common pest on calathea (prayer plant) foliage, including calathea varieties grown as houseplants; they take hold on the patterned leaves of this tropical, humidity-loving genus that the book explicitly recommends keeping warm and humid

Why does my Calathea Corona have spider mites?
Spider mites are listed as the most common pest on calathea (prayer plant) foliage, including calathea varieties grown as houseplants; they take hold on the patterned leaves of this tropical, humidity-loving genus that the book explicitly recommends keeping warm and humid
Cause
Spider mites are listed as the most common pest on calathea (prayer plant) foliage, including calathea varieties grown as houseplants; they take hold on the patterned leaves of this tropical, humidity-loving genus that the book explicitly recommends keeping warm and humid.
Solutions
- Wash all the leaves and stems of the calathea corona with a gentle stream of water, then wipe with a mixture of castile soap and water, and finally rinse again with water.
- Make your own insecticidal soap spray by combining 1 Tbsp. (15ml) of castile soap with 3 oz. (1 L) of water; shake well and use immediately, and avoid neem oil because neem oil does not agree with calatheas and will cause the leaves to turn yellow and fall off.
Prevention
Keep the calathea corona in a warm, humid environment with frequent misting, a pebble tray, or a humidifier, and regularly inspect the undersides of the leaves so an infestation can be caught before it spreads across the foliage.
