We cut the tree down and removed the main root but the remaining roots continue to sprout everywhere including my lawn. I have a retaining wall and the house foundation that I am concerned about being damaged. Any suggestions? I am tired of digging up roots that have an inch diameter out of my lawn. Thanks, Lisa
I have a cottonless cotton wood tree and it is sending out little sucker trees from its roots. How can I get rid of these suckers without killing the tree? Thank you.

We have had success with rooting an old, historical cottonwood with cloning gel. What next? We have leaves on two of our rooting attempts, but it is fall. What should we do with these two successful rootings over the winter?
I would continue to grow the propagated tree cuts under grow lights for the winter.
By spring the trees should be ready for planting outdoors.
How long does a cottonwood tree shed the cotton seeds? They are a nuisance around our pool and have clogged air conditioner units. Will regular pruning lessen the shedding of the seeds?
Bought a house in Arizona that has 6 cottonwood trees that seem to have matured overnight in that they doubled in size in 8 months. Trees are on a drip system and get water twice daily for 30 min 6am and 6pm. I noticed I have lots, some very large, sprouts and was wondering if I can cut the sprouts at their base where they are coming off the roots and then use a tree sealer. Will this stop them from growing back? I don't what else to do because I don't want to kill the trees by using a weed killer on them. I have a tight budget so I have to find something I can do myself. Thanks for advice!
I think cutting back the sprouts at the roots will be an effective strategy. You will have to be vigilant, because other sprouts may emerge from other areas of the soil, which you will have to keep removing. The tree sealer may not be helpful, since the sprouts won't grow from the cut end but from further down or directly from the roots, unless you can use it to seal cracks where the sprouts may emerge.
Why do cottonwood trees sap from some branches?
It sounds like your Cottonwood Tree is infected with Bacterial Wetwood or Slime Flux disease.
Here are some links that have more information for you.
Is it sick? Will it die? Will it spread to the other trees? Should I have it removed?
This could be a Canker disease or Bacterial Wetwood.
I've listed several articles to help you with your diagnosis.
You may want to have the tree inspected by a certified arborist.
