Cottonwood Seedling Infestation

araknes(z8 WA)August 21, 2005

This is our first year in this house and discovered that there is a large grove of cottonwood trees in a greenbelt down the street. During spring our yard was covered with cotton -- we tried to clean it up but obviously didn't do a very good job because all of our planting beds, flagstone joints, and gravel paths have been full of cottonwood seedlings all sprint and summer. I pull out buckets of this stuff every week but a few days later it's as thick as ever. It seems endless! Any suggestions to get rid of all these seedlings growing in my mulch? I'm debating re-mulching but am worried that somehow the cottonwoods will find their way through and I'll be pulling them out again in a few weeks.

Thanks for your help!

From my experience, I'm afraid you're stuck with them.
Pulling is the only way to effectively reduce numbers but you must get down below the crown or they grow back.
They do kill with round-up and 24D but the dead stocks will need to be pulled anyway.
Good solid ground cover will stop them from sprouting.
