We have cattails growing in the ditch behind our house and this ditch is there for drainage of bay water during high tide and hurricanes. Should they be removed?
It's true that if cattails' growth gets thick, they can impede flow of water through the drainage ditch. They probably should be thinned if not completely removed. You can contact the county extension service for advice on practical solutions for your area.

Cattails are growing wherever they have been before, but none of them have catkins, just the plants. This is in ND and SD.
Cattails are directly impacted by environmental conditions.
Water, temperatures and wind will effect the plants.
Last year the cattails were thin here, and this year the cattails are quite abundant. I am in Souther MN, we have had quite a bit of heavy wet weather.
I have ordered cattail seeds. When do I sow the seeds in my pond? Oh, and in the case you say cattails won't grow in Alaska, There are cattails growing in the lakes and ponds near Fairbanks, Alaska. Thanks, Joe
You can place in pots or direct sow.
The article recommends glyphosate - definitely a VERY BAD idea!!
We offer 'digging up' as an option for removing the cattails as well.
We understand the concerns on the use of glyphosate herbicide and offer as much information as available to the gardeners seeking information.
I am going to spray the cattails with RODEO. Do I spray the entire plant or do I spray at the water line to kill the plant?
Cattails are a perennial with a rhizome. Spraying anytime may kill the foliage, but not the plant. The greatest success comes in spraying glyphosate in the fall after the plant has flowered and as the plant begins to strengthen its root system for overwintering.
Use an aquatic labeled glyphosate.
I have viewed the care of cattails in containers but it doesn't reference the medium used (potting soil, etc. and how much. It does state that 12 inches of water is needed. Is that a hard rule What would be the minimum & maximum amount of water. Is it changed? I know nothing about gardening but I would like to grow these cattails. I am in a Zone 6. Thank you for your response. tony Parone
You can use any good quality potting soil. I would make sure to have a large container. These will require a good deep pot. I would also advise having dolomitic lime on hand, as this will save you a lot of trouble when it comes to controlling the pH. This will do it for you. You may need an all purpose fertilizer after a few months.
When do cattails bear their cylindrical brown blooms? What month of the year? are they native to river banks in Indiana?
Please do your homework well and get your cattail ID confirmed. Many cattails in Indiana are invasive species. https://www.nps.gov/rlc/greatlakes/upload/CATTAILS-for-website.pdf
Cattails are produced in late summer.
