River Birch Tree Is Dropping Long Worm-Like Seeds And Small Yellow Things

Question From: J. Stone - Charleston, West Virginia, United States
Q: My river birch tree has dropped long worm-like seeds, then whirlybird things. Now it's dropping small yellow-like things for 3 weeks now. It looks like it's snowing. I have to constantly sweep them off my porches and my driveway is a mess! What's wrong with it and how long will this last. Thank you very much!

A: Your birch tree bloomed and developed seedlings. The will be gone in a couple of weeks. Best And Happy Yardening, Nancy
