Painted Brake Fern Care Guide: How to Grow Pteris Tricolor Indoors or in Shade

The Painted Brake Fern, botanically known as Pteris tricolor (also sold as Pteris quadriaurita ‘Tricolor’), is a striking evergreen fern prized for its bronze‑red young fronds that mature to rich green. Compact, elegant and surprisingly tough, it’s an ideal fern for indoor growing, shaded patios, conservatories and woodland‑style planting.

What Is a Painted Brake Fern?

Painted Brake Ferns belong to the Pteris genus and are known for their upright, architectural fronds and vivid colour shifts. New growth emerges coppery‑bronze or reddish before softening into mid‑green tones, giving the plant season‑long interest even indoors.

Unlike many delicate ferns, this species copes well with varied light levels and remains tidy without constant pruning.

Ideal Growing Conditions

Light

• Bright, indirect light indoors
• Partial shade to full shade outdoors
• Avoid strong direct sun which can scorch fronds

Watering

• Keep soil consistently moist, never waterlogged
• Allow the surface to dry slightly between waterings
• Reduce watering slightly in winter, but never let it dry out fully

Humidity

• Enjoys moderate to high humidity
• Ideal for kitchens, bathrooms and conservatories
• Occasional misting helps maintain leaf quality

Soil

• Moist, free‑draining, humus‑rich compost
• Peat‑free fern or houseplant compost works well

Indoor vs Outdoor Growing

Indoors
Painted Brake Ferns excel as houseplants, especially in bright rooms away from radiators and draughts. Their colour holds well through winter, making them excellent long‑term indoor foliage plants.

Outdoors
In the UK, they suit sheltered patios, shaded borders and woodland planting. Protect from frost in colder areas, or grow in containers that can be moved indoors over winter.

Common Problems (and How to Fix Them)

• Brown tips → Air too dry or compost too dry
• Faded colour → Light too low
• Drooping fronds → Inconsistent watering

Once settled, Painted Brake Ferns are largely pest‑free and low maintenance.
