Calathea warscewiczii, also known as Jungle Velvet or Velvet Calathea, is a stunning tropical plant known for its uniquely patterned and vibrant leaves. This Brazilian native thrives indoors when provided with the right care and growing conditions. Read on to learn everything you need to know about successfully growing and caring for Calathea warscewiczii in your home.
Light Requirements
Calathea warscewiczii prefers bright, indirect light. Place it near an east or west facing window where it will receive gentle morning or afternoon sun. Direct sunlight will scorch and fade the leaves.
This calathea does best with 12-14 hours of consistent daily light. The leaves will begin to lose their vibrancy if light levels are too low. Rotating the plant every few days can help ensure even light exposure. Use sheer curtains to filter harsh afternoon sun coming through a south or west window.
Supplement with a grow light during shorter winter days if needed. Position the light 2-4 feet above the plant. Fluorescent plant grow bulbs or full spectrum LED grow lights work well.
Ideal Temperatures
Warm indoor temperatures between 65-85°F (18-29°C) are ideal for Calathea warscewiczii. Temperatures cooler than 60°F (15°C) can cause leaf damage. Avoid drafty windows and vents to prevent cold air damage.
In the summer, temperatures above 85°F (29°C) may cause leaf scorching. Move the plant to a shadier spot or use an air conditioner during hot weather. The leaves will also benefit from regular misting on very hot days.
Humidity
High humidity is essential for thriving Calathea warscewiczii plants. This tropical variety thrives at 60-80% relative humidity. Less than 40% can cause crunchy, browning leaf edges.
Use a humidifier nearby to increase moisture in the surrounding air. Group plants together to create a microclimate. Pebble trays or humidifying pebbles can also help boost local humidity. Mist the leaves daily or place the pot on a wet pebble tray.
Soil Needs
Well-draining, nutrient-rich soil is vital for growing healthy Calathea warscewiczii. Aim for a soil mix containing:
- 2 parts potting soil
- 1 part peat moss or coco coir
- 1 part perlite or bark chips
This blend will hold some moisture while still allowing excess water to drain. The peat and perlite will help aerate the roots and prevent soggy soil.
When re-potting, choose a container with drainage holes just 1-2 inches wider than the current pot. Do not use a mix that is too dense or moisture-retentive. Calathea are prone to root rot if overwatered.
Watering
Allow the top inch or two of soil to dry out between waterings. The leaves will become limp and droopy when the plant needs water. Water thoroughly until it drains freely from the bottom drainage holes, then discard any excess from the saucer.
In general, Calathea warscewiczii will need water every 7-10 days in warmer months. Reduce watering frequency to every 10-14 days in the winter when growth slows. Take care not to overwater, as it can lead to root rot.
Always use room temperature filtered or distilled water if possible. Tap water containing salts, chlorine, or fluoride may cause leaf tip burn. Empty any water pooled in the leaves to prevent disease.
Fertilizer
Feed Calathea warscewiczii with a balanced liquid fertilizer diluted to half strength every 2-4 weeks during the spring and summer. Reduce to monthly applications over winter.
Look for a fertilizer labeled for tropical foliage plants. Avoid over-fertilizing, as excess salts can burn the leaf tips. Rinse the leaves after application to prevent buildup.
If desired, use a time-release fertilizer pellet at the start of the growing season in early spring. Mix it gently into the top few inches of soil and reapply every 6 months per package instructions.
Pruning
Prune off any dead, damaged, or diseased leaves at the base of the stem. Use sterilized pruning shears to prevent spreading disease. Avoid removing more than 20% of the foliage at one time.
Occasional pruning encourages bushier new growth. But take care not to over-prune, as Calathea warscewiczii needs lots of leaves for photosynthesis. Only prune for shaping, removing dead growth, or rejuvenating a struggling plant.
Propagation
Calathea warscewiczii is easily propagated by division when re-potting overgrown plants. Carefully separate rooted sections at the root ball, ensuring each division has 3-5 leaves and established roots. Re-plant divisions in small pots using well-draining soil.
This calathea can also be propagated by stem cuttings. Use a sterilized knife or pruners to take 4-6 inch cuttings below a leaf node. Remove the lower leaves and place the cutting into water or moist soil. Keep it warm and humid until new roots establish in a few weeks before re-potting.
Common Problems
Calathea warscewiczii is prone to a few issues when not provided with proper care:
- Leaf curling – Usually caused by too little humidity. Increase humidity levels and mist regularly.
- Leaf spotting or browning edges – Typically from dry air or irregular watering. Improve humidity, water carefully, and avoid drying it out.
- Root rot – Stem and base turn mushy and black from overwatering. Allow soil to partly dry out between waterings.
- Fading or curling leaves – Can indicate too little light. Slowly acclimate to brighter indirect light.
- Pests like spider mites – Wipe leaves with neem oil or insecticidal soap spray to remove.
Tips for Optimal Growth
Follow these tips for successfully growing healthy Calathea warscewiczii:
- Provide bright, indirect sunlight 12-14 hours per day. Rotate the plant periodically for even exposure.
- Keep temperatures between 65-85°F. Avoid cold drafts and hot midday sun.
- Maintain high humidity around 60-80%. Use a humidifier and mist leaves daily.
- Plant in well-draining soil. Allow the top few inches to dry between waterings.
- Fertilize every 2-4 weeks during the growing season with diluted liquid fertilizer.
- Prune only when necessary to shape, remove dead leaves, or rejuvenate.
- Watch for pests, treat promptly with neem oil or insecticidal soap spray.
With the right care, Calathea warscewiczii will thrive indoors and delight you with its stunning patterned foliage!

How much light does a Calathea Warscewiczii need?
These plants prefer bright, indirect light. An east or west facing window is ideal. Direct sun will scorch the leaves. Give Calathea Warscewiczii 12-14 hours of consistent, gentle light daily. Supplement with grow lights in winter if needed.
What temperature is best for Calathea Warscewiczii plants?
Calathea Warscewiczii grow best in warm temperatures between 65-85°F (18-29°C). Cooler temperatures under 60°F can cause leaf damage. Avoid drafty areas and use a space heater or air conditioner to maintain ideal temperatures.
How often should I water my Calathea Warscewiczii?
Allow the top 1-2 inches of the potting soil to dry out between waterings. Water thoroughly until it flows from the drainage holes. In general, Calathea Warscewiczii needs water every 7-14 days depending on light, humidity, and temperature conditions.
Why are the leaves on my Calathea Warscewiczii curling or browning?
Curling or browning leaves usually indicate conditions are too dry. Increase humidity through misting and using a humidifier. Make sure to water regularly when the top soil becomes slightly dry. Avoid dried out soil.
Should I mist my Calathea Warscewiczii?
Yes, misting is very beneficial for Calathea Warscewiczii plants. The leaves appreciate humidity levels between 60-80%. Mist the leaves daily to boost moisture and prevent browning edges. Group plants together and use a humidifier for added humidity.
What’s the best fertilizer for Calathea Warscewiczii?
Fertilize Calathea Warscewiczii every 2-4 weeks during the growing season with a balanced liquid fertilizer diluted by half. Look for something labeled for tropical houseplants. Reduce fertilizing over winter.
How do I propagate new Calathea Warscewiczii plants?
These plants propagate easily through division or stem cuttings. For division, separate rooted sections when re-potting. For cuttings, take a 4-6 inch stem cutting and root it in water or moist soil until new growth emerges. Then plant in potting mix.
Why are the leaves on my Calathea Warscewiczii turning yellow?
Yellow leaves often indicate overwatering. Allow the soil to partly dry out between waterings. Root rot from too much moisture causes yellowing leaves. Improper watering or dry air can also cause yellowing. Adjust watering frequency and increase humidity.
