Hi alison~

I am in chas too!
The live oak is called a live oak because it appears that it never loses ites leaves. But that isn't altogether true. They hang on until the spring when the newest buds are established and are leafing out. The springtime is also when they drop all that hateful stuff bearing their pollen! Very plentiful & it makes a good addition to the compost heap.
The acorns drop in the fall.

If you have never done so, take the trip out to see the Angel Oak on John's Island. It is near the intersection of Maybank Hwy & Bohicket. There is a gift shop there that may have some info on this majestic tree.

I was there a few weeks ago & took this shot. It is free to get in...

One thing that is becoming important to Live Oak owners (and other oaks) is preventing the possible infection by a fungus spread by the Nitidulid beetle which is attracted to sap leaking from pruning cuts or injuries from storm damage etc. It is called Oak Wilt and it can kill your tree (even an old one) quickly. Find out if your area is affected and follow the instructions of your state agriculture extension. The recommened prevention here is to always prune in the months BEFORE spring and paint all cuts and injuries immediately. This goes ditto for other oaks which can spread the disease to others around them, such as red oaks and even white oaks.
