Bracken Plant Care
Pteridium aquilinum (L.) Kuhn
Updated · Sources · How we source care data
Pteridium aquilinum, commonly called bracken, brake, pasture brake, common bracken, and also known as eagle fern, is a species of fern occurring in temperate and subtropical regions in both hemispheres. Originally native to Eurasia and North America, the extreme lightness of its spores has led to it achieving a cosmopolitan distribution.

How do you care for Bracken?
Water Bracken every 7–10 days, letting the top layer of soil dry out between waterings, and give it filtered sunlight or partial shade. It prefers temperatures of 60–75°F (16–24°C) and 50–70% humidity. Fertilize it every 6 months during the growing season.
Where Is the Bracken Native To?
What Is the Bracken?
Bracken (Pteridium aquilinum) belongs to the Dennstaedtiaceae family within the Pteridium genus. Bracken is native to Eurasia and North America, the extreme lightness of its spores has led to it achieving a cosmopolitan distribution. Bracken is also known as Bracken Fern, Common Bracken, Eagle Fern.
Bracken displays a large, spreading fern growth habit, reaching up to 3 ft tall with a spread of approximately 4 ft. Bracken produces non-flowering plant.
Leaf size: approximately 24 inches.
How Often Should You Water a Bracken?
Pteridium aquilinum requires watering every 7–10 days. Allow the top layer of soil to dry between waterings to prevent root rot. Reduce watering frequency during winter when growth slows.
Watering Frequency
Every 7–10 days
Let soil partially dry between waterings
What Light Does the Bracken Need?
Bracken thrives in filtered sunlight or partial shade. Avoid placing Bracken in direct, harsh sunlight for extended periods, as this can scorch the foliage.
Light Requirement
Filtered sunlight or partial shade
What Temperature and Humidity Does the Bracken Prefer?
Pteridium aquilinum grows best at temperatures of 60–75°F. Bracken prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

What Soil Mix Works Best for a Bracken?
Moist, well-draining soil with high organic matter content. Good drainage is essential for Bracken to prevent waterlogging, which leads to root rot and fungal issues.
How Often Should You Fertilize a Bracken?
Feed Bracken every 6 months during the growing season (spring and summer) with a balanced fertilizer diluted to the strength on the label.
Pause feeding in autumn and winter, when growth slows, and never fertilize dry soil — water first.
Fertilizing
Every 6 months
During the growing season
The PlantoScan app can remind you when to water and when to fertilize each plant.
How Do You Repot a Bracken?
Repot every 1-2 years in spring. Choose a pot one size larger than the current container, and ensure it has drainage holes to allow excess water to escape.
How Do You Propagate a Bracken?
Bracken can be propagated through spores. Similar propagation techniques also apply to common bracken plant care, which shares the same genus.
Is the Bracken Toxic to Pets and Children?
Pet safety not verified
The ASPCA does not list Bracken, so we can't confirm whether it is safe for cats and dogs. Keep pets from chewing it as a precaution.
This is a general caution, not veterinary or medical advice. If your pet ate a plant, contact your vet or animal poison control.

What USDA Hardiness Zone Does the Bracken Need?
Bracken grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. Bracken is native to Eurasia and North America, the extreme lightness of its spores has led to it achieving a cosmopolitan distribution. In cooler regions, grow Bracken as a houseplant or bring it indoors before the first frost.
