Growths on weeping willow tree trunk #411275

I have these growths on the trunk of my weeping willow. Hundreds of clusters, mostly about the size of a dime. The leaves are growing thick and green and show no signs of any spots, etc.
I found a picture online that closely matches the clusters, but it didn't say what the disease is or if it could be treated.
Can you give me information on how to save my tree?

Willows can grow adventitious roots or air roots that will extend to the ground and buttress the tree in its natural habitat along the bank of a river. If you search "willow adventitious roots" you'll see images that are like your tree.
1. I'm amazed to get an answer so quickly on a Sunday of what is a four day weekend to working people.
2. I never would have guessed at the word 'adventitious', so I really appreciate learning about it.
3. I'm assuming my tree should be OK. It's probably my fault it's making all those little roots, I've been snipping off little branches that are growing where I didn't want them. I'll stop pruning it during the summer.
4. THANK YOU! I'm immensely relieved and thankful for your response.

I don't think the adventitious roots came from pruning. They are anchor roots for a tree that lives in very wet conditions in nature. I found an article on pruning weeping willow you might enjoy.
