Q.Health Of Katsura Trees In Neighborhood

Zone 98029 | justincykler added on January 26, 2022 | Answered

Our neighborhood has 40+ Katsura trees lining our alley. They have grown tall over the last 15 years and now are creating lots of damage on the fences and rooflines that end up being under the canopy (especially during summer and fall). It seems that the trees drop a lot of “stickiness” on everything and anything that lies temporarily or permanently under them. Cars have even been damaged from the “sticky sap”. Do these Katsura trees typically do this after mature, or is it that they are potentially unhealthy or diseased?

This can be normal with high variability in temperature and humidity. This can be a sign of insect pest infestation, though, as well as bacterial infections.

Unfortunately, your photos did not come through. I will be unable to assess the situation, further.
