    Cutting tool sterilization

    In more temperate plant zone 7 and others, it's always paint-oaks and tool-sterilization season. Some say screaming-hot summer, eg, July and August, are safe. But in central Texas, weather changes can be fast and fickle.

    Black ooze is oak's own Halloween decor?

    (jk.) What is this? Sticky. No strong smell. In photo, light areas are where I scraped bark to investigate seepage. Appeared overnight. Rain washed it away. Hasn't returned in 2 days. Texas red oak has several long scars I just guessed were antler rubs. The actually scary part: the tree is near...

    hackberry split

    This fissure recently appeared in my hackberry. It runs 2/3 the length of the tree, which is 2.5 stories tall. It's very near my house. What to do? Remove it or treat somehow? How urgently should I act? Thanks in advance for your help.

    Injected live oak at risk?

    I appreciate your added support for the "treat it" theory. Any other opinions? Some arborists say Alamo can stress an uninfected tree; so don't inject unless there's a threat -- or maybe they said "a new threat." Potential threats to my live oak may include 1) It's 10 yards from an untreated...

    Injected live oak at risk?

    A red oak (6 inches DBH) started dying from oak wilt about three weeks ago. Five feet away is a live oak (8 inches DBH) injected with Alamo almost exactly two years ago. Should I inject Alamo again? Thanks in advance for your help.

    Oak wilt or not?

    I don't know if oak wilt is too close to my motte of 3 big live oaks. For years, my Central Texas neighborhood has been an oak wilt center. My neighbor didn't know oak wilt existed but she had 3 sizable live oaks die "in the last year or two." I didn't see the leaves. This year, 150 feet from...

    Abandon Alamo for oak wilt?

    I've had good luck with Mauget's Tebuject (tebuconazole) micro injections for 10+ years. They sell it for oak wilt etc. but propiconazole is probably the only one officially approved. Alamo makes more sense because of the high volume of liquid used. But it's harder to do than micro injection.

    Abandon Alamo for oak wilt?

    People seem to avoid this question. Is it either too controversial or too basic to warrant a response? So double thanks for your insight and for responding at all. "They" are a couple of arborists who've seen my acre. They've been especially critical of me injecting "ordinary" trees as a ring...

    Abandon Alamo for oak wilt?

    "They" sometimes say Alamo loses preventive efficacy after several treatments two years apart. (I'm in an oak wilt center.) "They" say to spend the propiconazole $ on replacement trees. But I can't replace three big live oaks in a motte. I've successfully treated them and others three times...

    Lifetime limit on Alamo for oak wilt?

    Two related questions: An arborist told me that Texas A&M (Dr. Appel?) now says injecting propiconazole to prevent oak wilt can be done only twice, a couple of years apart, in a tree's lifetime. I can't confirm that online. Any opinions, facts? 2) I wonder if Mauget's Tebuject (tebuconazole)...
