Can I grow cattails in a small pond?

They are very aggressive and will quickly take over a small pond, so use a container to restrict their roots.

Do they need deep water?

They prefer shallow water, typically 0 to 30 centimeters deep.

Cattail.

Typha

Pronounced TIE-fuh

Also known as Bulrush, Bulrushes, Cattail, Cattail Bulrushes, Cattails, Cattails and Bulrushes, bulrushes and cattails, corn dog grass

Cattails are iconic wetland plants that thrive in shallow water or saturated soil. They are known for their distinct brown, sausage shaped flower spikes. These plants are excellent for naturalizing pond edges and supporting local wildlife.

At a glance

Care level: Easy
Plant type: Emergent aquatic perennial
Light: Full sun
Indoor light: Direct sun
Water: Every day
Mature size: 3 to 10 feet
Growth rate: Fast
Hardiness: USDA 3 to 10
Bloom time: Mid to late summer

Care

Keep the soil consistently wet or submerged in a few inches of water. Watch for yellowing leaves which may indicate the plant is drying out. These plants are very vigorous so keep them in containers to prevent them from taking over your entire water feature.

Watering: The soil must remain constantly saturated or submerged in water.
Feeding: Apply a slow release aquatic plant fertilizer once in the spring.
Pruning: Cut back dead foliage and spent flower spikes in late autumn or early spring.
Repotting: Divide the rhizomes every couple of years to keep the plant from becoming root bound.
Soil: Heavy clay or aquatic soil
Soil pH: 6.0 to 8.0
Temperature: -30 to 35°C
Humidity: 60 to 100%
Drought tolerance: Low
Lifespan: Perennial, can live indefinitely through rhizome spread.
Deer and rabbits: High

Signs it needs repotting

Roots growing out of the container drainage holes.
Plant growth slowing down significantly.
The container becoming unstable or crowded.

Safety

People: The plant is generally non-toxic, but the fluffy seeds can cause respiratory irritation if inhaled in large quantities.
Children: The sharp leaf edges and dense seed fluff can be irritating to small children.
Contact allergens: The leaves have sharp edges that can cause minor cuts.
Airborne allergens: The massive amount of windborne pollen produced in summer is a significant allergen for many people.
Edibility: Young shoots and rhizomes are edible when cooked, but ensure the water source is clean as they absorb heavy metals.

Grows in shallow water or mud

Height: 1.5 to 3m

Growing it

Propagation: division, seed
When to plant: spring, summer
Overwintering: The foliage will die back in winter, so you can cut the stalks down to the water line once they turn brown.
In containers: They grow well in containers, but use a large, heavy pot to prevent it from tipping over in the water.

Rhizome Division

1. Dig up a section of the rhizome in spring.
2. Cut into pieces with at least one growing bud.
3. Replant immediately in wet soil or shallow water.

Plant in a submerged container to prevent the rhizomes from invading the entire pond area.

Grows well with

Pickerelweed · It shares similar moisture requirements and provides a nice contrast in leaf shape.
Blue Flag Iris · This iris thrives in the same wet conditions and adds beautiful seasonal color.

Similar species

Common Reed · It is another tall wetland grass that is often confused with cattails.

Science

Where the name comes from

The name Typha comes from the Greek word typhein, meaning to smoke, referring to the use of the dried flower heads as torches.

Good to know

Cattails are often called nature's water filter because they absorb excess nutrients.
The fluffy seeds were historically used as stuffing for pillows and life jackets.
Native Americans used the pollen as a high protein flour additive.
