How to grow Typha
Whats common across all Typha varieties in our catalog — drawn from the care records of the 3 most-grown of them.
The Typha year
- DivideMarch and April100% of varieties
Lift and divide congested rhizomes to control spread or propagate new plants.
- Check for PestsJune and July100% of varieties
Inspect stems for boring caterpillars and wipe away aphid colonies on new shoots.
- Winter PrepNovember and December67% of varieties
Leave standing foliage intact through winter to provide wildlife cover and protect the crown from deep freezing.
- Spring CleanupMarch and April67% of varieties
Cut dead brown foliage and spent flower spikes back to the water line before new growth emerges.
Do
- Grow in full sun to ensure strong stem development and abundant flowering.
- Keep the soil constantly saturated or submerged, as drying out kills the root system.
- Use heavy, solid-sided pots to prevent the sharp rhizomes from escaping into the wider pond.
- Grow in heavy-duty containment pots to control the aggressive rhizomatous spread.
- Cut dead foliage back to the water level once a year in late winter.
Avoid
- Do not plant directly into unlined earth ponds or near flexible pond liners.
- Do not prune into live, green tissue during the active summer growing season.
- Do not handle the leaves roughly without gloves, as the sharp margins can cause skin cuts.
- Do not plant directly into unlined garden ponds or earth-bottomed features without root barriers.
What goes wrong with Typha
| Problem | What you'll see | What to do |
|---|---|---|
| Aphids | Clusters of small, soft-bodied insects on new green growth, causing minor leaf curling. | Blast the foliage with a strong stream of water to dislodge them; chemical controls are rarely necessary. |
| Spider mites | Fine webbing and stippling on the leaves during hot, dry periods. | Increase local humidity or wash the foliage thoroughly with water. |
| Cattail caterpillar (Bellura densa) | Larvae bore into the stems, causing localized wilting and collapse of the upper foliage. | Cut and remove affected stems below the water line to destroy the larvae inside. |
| Mammalian herbivores | Chewed foliage and damaged stems from deer or muskrats. | Install physical barriers or adjust water levels to discourage access. |
| Leaf spot fungi | Brown or black lesions appearing on the strap-like leaves during warm, humid weather. | Prune away heavily spotted leaves in late winter; the fungus rarely impacts the overall vigor of the plant. |
| Root rot | Decaying rhizomes and yellowing foliage under stagnant, low-oxygen water conditions. | Ensure some water movement or maintain appropriate water hygiene. |
| Fungal leaf spot | Small, dark spots on the foliage, typically occurring under poor air circulation. | Prune away affected leaves and improve spacing around the water feature. |
Making more Typha
Division
- Dig up established rhizomes in early spring before new growth begins.
- Cut the rhizomes into sections, ensuring each piece has at least one viable bud.
- Plant the divisions immediately into containers filled with heavy soil.
- Keep the soil saturated or shallowly submerged until new shoots emerge.
Rhizome Division
- Dig up an established clump in early spring just as new green growth begins to emerge.
- Use a sharp spade or knife to slice the thick rhizomes into sections, ensuring each piece has at least one healthy growth bud.
- Trim back any damaged roots or old foliage to clean up the division.
- Replant the divisions immediately into saturated soil or heavy containers at their original depth.
