Care Guide

Light

Bright, indirect light is ideal.

• East or north-facing windows suit it well

• Avoid direct sunlight — can fade the pink markings

• Too little light may reduce vibrancy

‘Dottie’ tolerates slightly lower light better than lighter variegated Calatheas.

---

Watering

Calatheas prefer consistent moisture.

• Water when the top 2–3cm of soil feels slightly dry

• Do not allow soil to completely dry out

• Reduce watering in winter

Tips:

• Use room-temperature rainwater or filtered water

• Ensure the pot has good drainage

• Avoid letting it sit in water

Inconsistent watering can cause curling or browning edges.

---

Humidity

High humidity keeps foliage looking its best.

• Ideal range: 60–80%

• Benefits from a humidifier

• Avoid placement near radiators

Low humidity may cause crispy edges or leaf curling.

---

Temperature

• Ideal: 18–26°C

• Avoid temperatures below 16°C

• Protect from draughts and sudden temperature shifts

Stable warmth is key.

Soil & Potting Mix

Use a moisture-retentive but airy mix:

• Peat-free houseplant compost

• Perlite

• A small amount of bark or coco coir

The soil should stay lightly moist without becoming waterlogged.

---

Feeding

Feed during the growing season (March–September):

• Balanced liquid fertiliser every 4 weeks

• Use at half strength

• Do not feed during winter

Overfeeding can cause leaf tip burn.

---

Growth Habit

• Compact and clump-forming

• Typically grows 30–40cm tall

• Produces new leaves from the centre

Leaves gently lift and fold slightly in the evening.

---

Common Problems

Brown edges

• Low humidity

• Mineral-heavy tap water

Curling leaves

• Underwatering

• Dry air

Yellow leaves

• Overwatering

Calatheas can appear “dramatic” but usually recover quickly once conditions stabilise.

Styling Ideas

• Perfect for adding depth to bright rooms

• Stunning contrast against white walls

• Pairs beautifully with lighter variegated plants

• Ideal for shelves, desks or plant cabinets

This variety would sit beautifully within a dark foliage collection, adding contrast through its vivid pink detailing.
