As I write this, central Texas is experiencing its worst winter weather event in decades (so what else can I do but write?). Having done tree work here for 40 years now, I've seen quite a few cold weather episodes in Austin. There was a five day stretch in December of '83 where we never got out of the 20's.
Many palms and most tallow trees around Austin froze to death that year, but there wasn't any precipitation, so breakage from snow and ice wasn't an issue. A couple years later ('85) we had two events a couple weeks apart that totaled about 7 inches of snow but also pretty bad icing, and we got some breakage with that.
In '89 we got the coldest blast I can remember, down to about 4F, but it was a quick dip, and I don't remember a lot of breakage with that one. Oak wilt continues to be an issue throughout Austin, central Texas and much of the central part of the U.S. This often fatal disease is spread by a fungal organism known as Bretziella fagacearum (previously Ceratocystis f., but scientists often change organism names just to mess with us arborists!)

Because I personally provide the services offered, I am usually in the field all day, everyday except Sunday. Please leave a number you can be reached at before 9 a.m. OR between 5 p.m. and 8:30 p.m., which is when I usually return calls. If you can only be reached during regular business hours, leave that number and let me know.
Oak Wilt
Report
Oak wilt is a very complex disease. This information is only intended to address how oak pruning impacts the spread of the disease. This is due in large part to the prevalence of live oaks here, and the propensity for root grafting which this species has. It has been recognized by researchers and expert arborists that the vast majority of the spread of oak wilt occurs underground, from live oak to live oak, through these grafts.
Pruning Tips
Report
Pruning is very likely the most common tree care practice in the U.S., representing a very large majority of the annual income produced by tree care service companies. But how beneficial is it? The answer is, when necessary and done properly, it can be very beneficial. When done improperly, it can be quite detrimental.
