Pond Boss Forums INTRO Questions & Observations Will drying kill cattails?

The cattails never came back. It seems the pond draining, and drying out, killed them.

John, has the pond seen a full season with water in it yet?

As esshup suggests, refilling the pond may see some renewed cattail growths - all depending. If the all the roots died and decayed, then regrowth from roots should not happen. However do not discount the dormant, sprouting ability of old cattail seeds. I do not know if that has ever been researched. Whatever develops, remember to always stay current with controlling them each year. Cattails can easily become overabundant and troublesome.

I would agree with Bill. We put in a new pond last year on land where there were no active cattails, only a couple wet areas 1/4 to 1/2 mile upstream in an irrigation ditch. Yet this summer I pulled over 400 cattails that had seeded along the banks. I cannot discount the viability and tenacity of seeds.

Yes, from late fall 2022, until early summer this year, it was nearly brimming full. It has dropped some since then, due to persistent local drought.

Cattails never came back. There might be some other mechanism going on. After a couple of cutting sessions, the large cattail patch in my other (1/4 acre) muddy pond has 95% died out.

Nice "win" on the cattails!

Some tree species can be killed when you continually cut them back after each explosion of new growth. The energy for growth is (mostly) stored in the roots, so eventually you can exhaust the tree and kill it.

No idea if that works on cattails, but it does align with your results.
