San Diego Coastal area Liquidambar

36yo tree with a few brown leaves and a small section of leaves with Fall colors....is this a water issue?

 

Likely a shortage of water yes as it is a tree that likes moist conditions, but needs photos to see more clearly.

 

Have a look at Attach photos and files | UBC Botanical Garden Forums and type a reply with the photos, whole tree and close-ups.

 

Thank you that's what I thought.
