Oak wilt
Austin TV news station said something like 20,000 live oaks have died due to
recent oak wilt problem. Also, they implied the recent wet weather from the last few months promoted it. And, also, there is no treatment to eradicate oak wilt. A local Austin tree arborist was part of that particular news clip. Video also included visuals of the wilt symptoms on the bark of the trees. Saw similar on some of the live oaks near my home inside the yard fenceline last year. Used a garden hose spray fungicide a couple of times last year, cut out the dead branches and so forth as well. Used boric acid to drive away the acrobat ants. Not a sign of the wilt or the ants on the trees this year. The trees are also getting water from a french drain with diluted sulfuric acid. Originates from aeration filtration system for hydrogen sulfide gas for my well water system. Maybe nature fixed it with rain at this particular location, I don't know. No more wilt. Dave |

Oak wilt
Good info...I've seen some of it before--a few years ago. We had an oak
that faltered but it was not wilt. It dropped some huge limbs and part of the tree was gone, but when they came out to take it down, they came to the front door and said part of it was still alive and begged us to let them try to save it. Well, OF COURSE! They cut it way back and we spiked around it with a few fertilizer stakes and watered it and it recovered. Wow, what a relief. What a devastating and difficult to halt disease oak wilt is. I can not imagine how much it costs to trench like that. The mind reels.... I remember when Dutch Elm disease took all the trees in our neighborhood when I was a kid. We had an incredible elm out behind our house. It shaded the whole house (big 2 story) and the year we took it down we had to get central A/C. So sad. -- ie ride fast, take chances.
