Marantaceae Care

Marantaceae Care in Phoenix

(Calathea, Goeppertia, Maranta, Stromanthe, Ctenanthe)

Plants in the Marantaceae family, often called Prayer Plants, include Calatheas, Marantas, Stromanthes, and Ctenanthes. They are known for their patterned leaves and the unique way many varieties fold their leaves up and down with the light cycle. These tropical plants can be considered “high-attention” houseplants, but with the right routine, they thrive beautifully in Phoenix homes.

Light

Prayer Plants prefer bright, indirect light. They are sensitive to harsh sun, especially in Phoenix summers.

Best placements include:

• East-facing windows

• Bright rooms with filtered light

• Bathrooms or kitchens with high humidity

• Near walls that reflect light rather than direct sun exposure

Avoid direct afternoon sunlight, which can bleach or scorch thin foliage.

Watering

Marantaceae plants like even moisture and are not forgiving when the soil dries fully. In Phoenix, small nursery pots dry quickly.

Watering guideline:

• Late spring and summer: About every 4 days

• Fall and winter: Every 6 to 8 days

Let the top 1 inch of soil dry before watering again. Always water thoroughly until excess drains out, and never let the plant sit in standing water.

For best results, use filtered or distilled water. Tap water minerals and chlorine often cause crisp edges, brown spotting, and leaf curl.

Humidity

These plants love humidity, making moisture a top priority in the desert.

Ways to help:

• Place near a humidifier

• Group with other plants

• Bathroom placement if bright enough

• Light misting for extra support during dry months

Avoid AC vents, heater vents, and drafts, which dry foliage rapidly.

Soil and Repotting

Use a light, moisture-retentive but well-draining soil. A mix of indoor potting soil, coco coir or peat, perlite, and a bit of orchid bark works well.

Repot every 1 to 2 years to refresh soil and support steady growth.
Maricopa Botanicals offers repotting services if you want expert help transitioning your Prayer Plants.

Fertilizing

Feed every 4 weeks in spring and summer with a gentle fertilizer.
Our house-made liquid fertilizer works especially well, as these plants prefer mild nutrients.

Pause feeding in winter when growth slows.

Cleaning and Maintenance

Dust blocks light and contributes to leaf stress. Wipe leaves regularly with our natural leaf cleaner to boost shine and photosynthesis.

Remove damaged or crispy edges as needed to keep foliage tidy. Expect occasional cosmetic imperfections with these plants — it is normal, especially in dry climates.

Common Issues

• Crispy leaf tips and edges: Dry air, tap water minerals, underwatering

• Leaf curling: Soil too dry or low humidity

• Faded leaves: Too much direct light

• Drooping: Missed watering or temperature swings

Adjust watering and humidity first — this solves most issues.

Final Thoughts

The Marantaceae family may be dramatic, but they reward consistency with stunning foliage and lively leaf movement. Give them filtered water, bright filtered light, consistent moisture, and added humidity, and they will thrive in Phoenix homes.
